TRUE

B.2 Name

Zagreus Services LLC

The legal issuer of ORCA has not been expressly identified in official public sources relating to the ORCA token.

However, the fixed supply of ORCA was issued totally in 9 August 2021 (orcaEKTdK7LKz57vaAYr9QeNsVEPfiu6QeMU1kektZE) is conducted by a mint authority identified as “Orca Multisig Authority” (GwH3Hiv5mACLX3ufTw1pFsrhSPon5tdw252DBs4Rx4PV). This indicates that ORCA was created and distributed through an identifiable entity or group, and that this entity may be playing a role in the development and launch of the ORCA protocol.

Publicly available sources, notably an SEC-related document (https://www.sec.gov/files/orca-creative-061725.pdf), reference Zagreus Services LLC as part of “Orca” and involved in the core development activities relating to the protocol.

Another entity identified, according to the official Orca Protocol website (https://www.orca.so/privacy-policy), is Orca Management Company S.A., a Panamanian corporation, as one of the entities forming “Orca”. The entity is described on its official website (https://www.orcamanagementcompany.com/) as being instrumental in the design, development, and maintenance of the core infrastructure and ongoing growth of the Orca Protocol. However, this entity was incorporated in 2023, which postdates the full issuance of ORCA tokens, which occurred in 2021.

Accordingly, based on our best assessment, we regard Zagreus Services LLC as the entity most closely associated with the development of the ORCA protocol and potentially the coordination of the token issuance process.

While no conclusive or verifiable evidence was identified in Orca official public sources directly confirming the connection, we consider Zagreus Services LLC to be a Delaware legal entity. This assessment is based on the close alignment between the Delaware entity’s registration date in 2021, which coincides with the commencement of ORCA protocol activity, and the fact that the majority of Orca employees are located in the United States.

D.4 Crypto-asset project description

Orca is a decentralised exchange on Solana. The project enables users to swap supported Solana tokens, provide liquidity through concentrated liquidity pools and create token pools. Orca uses Whirlpools, a concentrated liquidity automated market maker program on Solana, which allows liquidity providers to allocate liquidity to specific price ranges rather than across all prices. Developers may also interact with Orca programmatically through its open-source smart contracts, software development kits and public API. The Orca project is governed through a decentralised governance system in which ORCA token holders may propose changes, vote on decisions and participate in shaping the protocol.

D.8 Description of past milestones

Past milestones

Orca launched on Solana mainnet in February 2021 as an automated market maker and received an early grant from the Solana Foundation. ORCA, the protocol’s governance token, was launched on 9 August 2021. In October 2021, Orca published a roadmap identifying planned developments including Whirlpools, additional token listings and liquidity pools, SDK upgrades, further integrations, improvements to the user interface, mobile user experience improvements, community development and broader access to ORCA.

In May 2022, Orca introduced Whirlpools, its open-source concentrated liquidity automated market maker (CLMM) program on Solana. It is used for swaps, liquidity position management, trading applications, autonomous agents and LP management bots. Orca also states that, throughout 2022 and 2023, third-party DeFi applications including Jupiter, Kamino and HawkFi built on top of Orca’s liquidity infrastructure.

In 2024, Orca supported Solana-based stablecoin and liquid staking markets, including PayPal USD, liquid staking tokens and liquid restaking tokens. ORCA was listed on Binance in December 2024. The Whirlpools program was upgraded on 28 May 2024 to support TokenExtensions, with later support for additional extensions including InterestBearing from 11 October 2024.

In early 2025, Orca reported that it had processed more than USD 300 billion in cumulative trading volume, supported more than 480 tokens and 1,295 trading pairs, and that more than 8.5 million unique wallets had interacted with the Whirlpools program since launch. Orca also reported that it had reached its highest single-day trading volume in 2025, exceeding USD 10 billion.

In March 2025, Orca launched the first two phases of the Liquidity Terminal. Phase 1 introduced visualisation tools for liquidity providers, including real-time price charts, position ranges and portfolio card views. Phase 2 added functionality to view and modify positions on the same screen, access position tables, create new positions without leaving the terminal and access the terminal directly from the portfolio. Orca also launched Liquidity Locking, short-term estimated yield timeframes, an enhanced portfolio experience and developer tooling improvements, including a transaction sender library for Rust and TypeScript.

In April 2025, the Orca community approved a protocol upgrade intended to realign protocol incentives. Following approval, Orca states that 25million ORCA tokens were burned, reducing total supply by 25%, and that a systematic ORCA buyback mechanism became live, using 20% of all protocol fees generated from Whirlpools to purchase ORCA on the open market. Orca also reported Liquidity Terminal refinements, a documented CPI integration repository for developers and comprehensive Token Extensions support across the platform.

xORCA staking is live, ORCA holders may stake ORCA to receive xORCA, participate in governance and receive exposure to fee-funded ORCA buybacks, subject to variable returns, a seven-day cooldown for unstaking and smart contract risk.

Liquidity Terminal is live and displays pool statistics, price charts, position management tools, history, closed positions and simulation functionality. Autoswap is live, enabling users to trade and deposit in a single flow, and that Liquidity Locking is live, allowing full-range liquidity positions to be locked while fees and rewards remain harvestable.

Orca has also introduced Adaptive Fee Pools and Dynamic Tick Arrays in June, 2025.Adaptive Fee Pools dynamically adjust trading fees based on market volatility. Orca’s Dynamic Tick Arrays update is expressly described as already live and supported by the latest Rust SDK, reducing the cost of creating liquidity pools and allowing tick arrays to initialise with minimal size and resize dynamically as positions are opened or closed.

D.8 Description of future milestones

Future milestones

Continued development of new products and features for liquidity providers and developers, further strengthening of Orca’s role as a liquidity layer for the Solana ecosystem, and support for innovation across crypto, DeFi and AI, are planned for the Orca project. Orca has also identified Liquidity Terminal Phase 3 as a forthcoming development, although official sources reviewed do not expressly confirm that this phase has been released under that name.

Orca has identified AI-driven DeFi as a future development area. Over the coming months, the project intends to expand AI-related functionality by improving developer tooling, including more robust APIs and documentation to simplify on-chain interactions; extending collaborations with additional AI agent frameworks and projects in the AI and crypto ecosystem; and introducing advanced trading features designed to automate and optimise liquidity provision on Orca.

D.9 Resource allocation

A total supply of 100 million ORCA was launched on 9 August 2021. The SPL token address for ORCA is orcaEKTdK7LKz57vaAYr9QeNsVEPfiu6QeMU1kektZ.

At launch, ORCA was distributed through a structured allocation, with an initial circulating supply of 5.25 million ORCA. Early distribution focused on ecosystem growth, including approximately 4 million ORCA for liquidity providers, 1 million ORCA for traders, and 250,000 ORCA for advisors. Additional tokens were gradually emitted over time through liquidity mining programs.

Orca Treasury holds protocol funds, coming from trading fees, to be used for development, grants and initiatives that support Orca’s growth. The treasury includes the Community ORCA Treasury and the accumulating Orca Fee Treasury, which may be used by token holders to fund development grants or other initiatives supporting the long-term health of the Orca protocol.

In 2025, an approval of a protocol upgrade proposal led to the permanent burn of 25 million ORCA tokens, reducing total supply by 25% and significantly increasing scarcity by permanently removing tokens from circulation. At the same time, a buyback mechanism was introduced, using 40% of the 12% share of trading fees allocated to the protocol fee mechanism. These funds are used to buy ORCA on the open market, and the purchased tokens are then deposited into the xORCA vault. The remaining 60% of protocol share is allocated to the Orca Fee Treasury for development, grants and operations. Increased protocol activity may result in a greater amount of protocol fees being allocated through this mechanism.

Part F - Information about the crypto-assets

N Field Content
F.1 Crypto-asset type

Crypto-assets other than asset-referenced tokens or e-money tokens

F.2 Crypto-asset functionality

ORCA is the native governance asset of the Orca protocol on Solana. The token is used to support decentralised decision-making, protocol alignment, xORCA staking and DAO participation. ORCA holders may vote on proposals concerning the Orca protocol, including proposals relating to fee structures, treasury allocation, upgrades and other protocol matters. ORCA and xORCA holders may also delegate voting power, submit proposals where applicable and participate in the election of the DAO Council.

ORCA may be staked to receive xORCA. The xORCA system is designed to allow participants to receive exposure to protocol fee-funded ORCA buybacks while participating in Orca governance. Protocol fees are partly used to buy ORCA and add it to the xORCA vault, and that the exchange rate between xORCA and ORCA increases when buybacks add ORCA to the vault without minting new xORCA. Unstaking xORCA requires a seven-day cooldown period before ORCA can be withdrawn. Returns from xORCA are variable and depend on trading volume and the ORCA price; xORCA also involves price exposure and smart contract risk.

ORCA is also used in Orca governance. Token holders can propose changes, vote on decisions and shape the future of the protocol. The governance process includes community proposals, discussion, voting by ORCA or xORCA holders and implementation of approved proposals by the team or DAO Council. Governance proposals may include protocol upgrades, parameter changes, treasury allocation and governance changes.

In the absence of such an agreement, the laws of the competent court will depend on the location of the issuer and the given crypto asset-holder and characteristic performance of the legal relationship, and any agreed intention of the issuer and crypto asset-holder.

H.2 Protocols and technical standards

Networking, transport and session

ORCA is an SPL token deployed on the Solana blockchain at mint address orcaEKTdK7LKz57vaAYr9QeNsVEPfiu6QeMU1kektZE, with an initial total supply of 75 million ORCA minted on launch date of 9 August 2021, and reduced to a fixed total supply of 75 million through a burn in April 2025. Token transfers and protocol interactions propagate over Solana's permissionless peer-to-peer network, which uses a gossip protocol for node communication and a leader-based block production model in which each slot has a designated leader responsible for producing a block. Validators propagate transactions to the current leader's mempool, where they await inclusion.

The Orca protocol's principal on-chain application is Whirlpools, an open-source concentrated-liquidity automated market maker deployed on Solana at program address whirLbMiicVdio4qvUfM5KAg6Ct8VwpYzGff3uctyCc. Whirlpools does not operate a separate networking layer; all interactions are submitted as standard Solana transactions via conventional RPC endpoints. A REST API for pool data and analytics is available for read-only queries. A separate program, Wavebreak, has also been deployed under the Orca protocol and audited independently.

Serialisation

Solana transactions use a compact binary encoding. Each transaction contains a header, an account addresses array, a recent blockhash, and one or more instructions. Instructions directed at the Whirlpools program are encoded using the Anchor framework's discriminator-based format, where each instruction is identified by an 8-byte discriminator derived from a hash of the instruction name, followed by its arguments in little-endian binary layout.

Cryptography and key formats

Solana uses the Ed25519 elliptic-curve signature scheme for transaction authentication. User wallets hold Ed25519 key pairs; the public key serves as the account address. ORCA token transfers require the owner of the sender's token account to sign the transaction using their Ed25519 private key. Associated Token Account addresses and all Whirlpools program-derived account addresses are computed using SHA-256-based program-derived address derivation, which applies a bump seed to produce a deterministic off-curve address from a set of seeds. This ensures that all account locations within the Whirlpools account hierarchy are derivable from their inputs and cannot be pre-signed by external parties.

Ledger

ORCA balances are recorded through Solana's token-account structure. The mint account stores global metadata for the ORCA token, including the fixed total supply and mint authority. Each token account records the mint it belongs to, the owner authorised to transfer tokens, and the amount held. Associated Token Accounts provide a deterministic default holding address for a given owner and mint combination.

The Whirlpools ledger is structured as a hierarchy of program-derived accounts. A WhirlpoolsConfig account defines the authorities governing the pools it owns, including default fee settings and the authority to collect protocol fees. Whirlpools visible on the Orca interface are derived from and controlled by a WhirlpoolsConfig account owned by the Orca Foundation; other users and protocols may deploy their own WhirlpoolsConfig accounts on the same program. A WhirlpoolsConfigExtension account holds additional authorities for managing Token-2022 assets and TokenBadge accounts. Each FeeTier account records a specific fee rate, defined per WhirlpoolsConfig and tick spacing. A Whirlpool account represents a concentrated-liquidity pool between a token pair and holds all pool accounting data alongside two vault token accounts, one per pooled token; only the Whirlpools program has authority to withdraw from those vaults, with neither the program owner nor the WhirlpoolsConfig owner holding withdrawal authority. TickArray accounts record the liquidity and fee state across price ranges. Position accounts represent a unit of liquidity distributed across a price range within a single Whirlpool, and position ownership is tokenised as a non-fungible token held in the owner's wallet. A PositionBundle account allows up to 256 positions to be managed under a single non-fungible token, reducing rent overhead when rebalancing frequently.

Execution

ORCA transfers execute through Solana's Token program. The Transfer instruction moves tokens between token accounts and requires the owner of the sender's token account to sign the transaction. The token's total supply is fixed at 75 million ORCA; no active minting capability is in operation against the ORCA mint. Whirlpools swap execution occurs through the deployed Whirlpools program, with all state transitions recorded in the Whirlpools account hierarchy described above.

Token standards

ORCA is an SPL token on Solana. The Token program contains the instruction logic for interacting with fungible and non-fungible tokens on the network. The Whirlpools program additionally supports the Token-2022 standard, also referred to as Token Extensions. V2 instructions handle tokens owned by the Token-2022 program, enabling pools that combine standard SPL tokens with Token-2022 assets. TokenBadge accounts serve as a whitelist mechanism for tokens carrying extensions that pose elevated risk to pool users; a token with such extensions may only be used for pool initialisation if the TokenBadge authority has issued a TokenBadge for that specific mint.

External APIs

Developer access to Whirlpools is provided through TypeScript and Rust high-level software development kits, lower-level generated clients for account, instruction, and error parsing, and core utility, mathematics, and quoting packages. A REST API exposes pool data and analytics for read-only integrations. These interfaces support transaction construction and data retrieval against the deployed Whirlpools program and do not constitute a separate settlement or consensus layer for ORCA

H.3 Technology used

Implementation and architecture

ORCA is implemented as an SPL token on Solana. Its on-chain representation follows Solana's mint-account and token-account architecture, separating the token's global identity and supply data from individual ownership records.

The Orca protocol's primary on-chain application component is Whirlpools, written in Rust and built using the Anchor framework. The Whirlpools monorepo contains the Rust smart contract, TypeScript software development kits, Rust software development kits, generated clients, core utility packages, documentation, and legacy SDK materials. Dependencies between packages are managed automatically by NX, which resolves the Rust and TypeScript codebases within the monorepo.

xORCA is the staking derivative of ORCA. Users stake ORCA to receive xORCA, which appreciates in value over time as protocol fee buybacks add ORCA to the xORCA vault. The exchange rate between xORCA and ORCA increases monotonically as buybacks accrue. Unstaking requires a seven-day cooldown period; upon initiating redemption, the user receives a Claim Ticket non-fungible token representing the pending claim, and the applicable exchange rate is locked at that moment. After seven days, the user may withdraw the corresponding ORCA amount.

Runtime and build parameters

The Whirlpools program is deployed using a verifiable build, meaning the hash of the on-chain program can be independently compared against the hash of the published source code to confirm build integrity. Local development targets Anchor v0.32.1 and Solana v2.1.0.

Dependencies

The ORCA token's direct on-chain dependency is Solana's Token program, which contains the instruction logic for token transfers and balance management. The Whirlpools program depends on the Anchor framework and Solana, and supports interactions with both the standard SPL Token program and the Token-2022 program. The monorepo uses NX for cross-package dependency resolution.

Deployment and addresses

The ORCA mint address is orcaEKTdK7LKz57vaAYr9QeNsVEPfiu6QeMU1kektZE. The Whirlpools program address on Mainnet-Beta is whirLbMiicVdio4qvUfM5KAg6Ct8VwpYzGff3uctyCc. All Whirlpools program accounts are program-derived addresses deterministically derivable from their parent account in the account hierarchy. Treasury-related addresses disclosed in the token treasury documentation include the Orca Fee Treasury, the Climate Fund wallet, the Community ORCA Treasury, and a wallet holding undistributed Solana fees.

Client interfaces and SDKs

Developers interact with Whirlpools through the orca-so/whirlpools TypeScript package and the orca_whirlpools Rust package for high-level operations. Lower-level integrations use generated clients for account and instruction parsing. These are non-consensus interfaces for constructing and submitting Solana transactions to the deployed program.

H.4 Consensus Mechanism

ORCA, as an SPL token on Solana, inherits Solana's network-level consensus for all token transfers and Whirlpools program executions. Ordering and finality are determined entirely by Solana's validator network.

Solana generates a source of time through a Verifiable Delay Function known as Proof of History. Time is divided into slots, each with a designated leader elected from the active validator set. The leader produces a block for each slot, and validators communicate their fork preference through signed votes identifying the validator and the block being voted for. The leader schedule is recalculated at epoch boundaries, with each validator updating its own root fork and leader schedule each time the slot height crosses an epoch boundary.

Tower BFT augments the voting system with lockouts. When a validator votes on a fork, a lockout is imposed for a number of slots during which the validator cannot switch to a non-descendant fork without forfeiting that commitment. Lockouts increase in duration exponentially with each successive vote on the same fork, making rollback of deeply confirmed forks progressively more costly. Validators that violate lockouts by voting for a diverging fork within the lockout window are subject to slashing, where the concurrent vote can be proven to the cluster.

H.5 Incentive Mechanisms and Applicable Fees

Network-level execution fees

Every Solana transaction requires a fee paid in SOL. The base fee is calculated per signature at 5,000 lamports, split evenly between burning and validator compensation. An optional priority fee may be set by the submitter to increase scheduling likelihood and is paid in full to the validator. The default compute-unit limit is 200,000 per instruction, with a maximum of 1,4 million compute units per transaction.

Orca does not charge fees to create a Whirlpool or to open a position in an existing pool. Solana network fees and rent apply to all transactions; rent associated with position creation is refundable on position closure, whereas network fees are not.

Protocol-level fees and economic flows

Whirlpool swaps may use either a fixed fee structure or an adaptive fee structure, depending on pool configuration. Under the fixed model, the total swap fee is a proportion of the input amount determined by the pool's stored fee rate, expressed in hundredths of a basis point. Of that total fee, the protocol fee is the portion diverted to the wallet controlled by the WhirlpoolsConfig collectProtocolFeesAuthority. Liquidity providers receive the remainder after the protocol fee is subtracted.

Under the adaptive fee model, the total swap fee is the sum of a static base fee and a dynamic variable fee component that responds to market volatility. The variable fee is computed using a volatility accumulator measuring recent price movement across tick groups and decays over time, allowing fees to rise during volatile conditions and fall during calm periods. A hard cap of 10% applies to the total adaptive swap fee.

The fee allocation for Orca-controlled pools is 87%of trading fees to liquidity providers, 12% to the DAO Treasury, and 1% to the Climate Fund. Of the 12% protocol share, 40% is used to buy back ORCA and add it to the xORCA vault as staker rewards, and 60% flows to the Orca Fee Treasury for development, grants, and operations.

Validator incentives

Validator incentives for ORCA transactions are Solana network-level incentives denominated in SOL. Base fees are split 50 % burnt and 50 % paid to the validator; priority fees are paid 100 % to the validator. There are no ORCA-denominated validator rewards and no distinct ORCA validator set.

Parameter governance and fee disclosure

Governance of protocol parameters is exercised by ORCA and xORCA holders. Any ORCA holder may submit a proposal; proposals are discussed on the Orca governance forum at gov.orca.so before on-chain voting on the Realms platform at realms.today/dao/ORCA. Voting weight is determined by ORCA and xORCA holdings, with xORCA carrying boosted voting weight relative to unstaked ORCA. Approved proposals are implemented by the protocol team or the DAO Council.

The DAO Council is an elected body that executes governance decisions and manages day-to-day protocol operations within bounds defined by token holders. Its remit covers parameter adjustments, emergency responses, routine maintenance, proposal execution, treasury management, and ecosystem relations. The Council operates transparently and may be replaced by community vote. Governance proposal types include protocol upgrades, parameter changes, treasury allocation, and governance changes.

ORCA MiCA White Paper

Part I - Information on risks

N Field Content
I.1 Offer-related risks

Market price volatility and liquidity

ORCA may experience material price fluctuations driven by broader crypto-asset market conditions, trading volume, venue depth, and investor sentiment unrelated to protocol fundamentals. Secondary-market liquidity can vary substantially across centralised and decentralised venues, and periods of low depth may widen spreads or make large positions difficult to exit at predictable prices.

Irreversibility of transactions

On-chain transactions involving ORCA are final once confirmed on Solana and cannot be reversed at protocol level. Mistaken, fraudulent, or accidental transfers cannot be recovered through any protocol mechanism; recovery depends entirely on control of the relevant private keys and the voluntary cooperation of any receiving party.

Network fee and failed-transaction cost risk

All Solana transactions require fees paid in SOL, including base fees and optional priority fees. Network fees are deducted before execution and are charged regardless of whether a transaction succeeds or fails. Increased network congestion can raise priority fees necessary for timely transaction inclusion, adding to the effective cost of ORCA-related activity.

Access and interface dependency

Access to the Orca protocol depends on the availability of the official interface, third-party wallets, RPC endpoints, and other access channels. The official interface may be restricted in certain jurisdictions. Third-party interfaces through which users may access the protocol are not owned, administered, or controlled by Orca, and may apply their own terms, restrictions, or access policies.

Key custody and wallet-provider risk

Control over ORCA balances depends on secure management of the private keys corresponding to the owner of each token account. Loss, theft, or compromise of private keys results in permanent loss of access to ORCA; no protocol mechanism can restore access or reverse a transfer made under a valid signature. Wallet software and hardware used to manage keys are third-party products not operated by Orca.

Regulatory, tax and jurisdictional risk

Digital-asset regulatory and tax frameworks remain evolving across jurisdictions. Changes in national or international rules may affect the permissibility, exchange, transfer, reporting, taxation, or value of ORCA. Regulatory developments may also restrict access to trading venues or interfaces through which ORCA is held or transferred.

Delisting Risks

Bitstamp Europe S.A. might remove the token from trading in line with Bitstamp Markets Trading Rules.

I.2 Issuer-related risks

Whirlpools configuration authority risk

The WhirlpoolsConfig account owner, currently the Orca for pools displayed on the Orca interface, holds authority over default fees, protocol-fee collection, and pool configuration. Compromise or misconfiguration of these authorities could affect fee collection, pool settings, or supported pool parameters. Vault assets can only be withdrawn by the Whirlpool program itself, not by the configuration owner, which limits but does not eliminate the scope of this authority risk.

I.3 Crypto-assets-related risks

Governance and utility dependency

ORCA's primary on-chain utility is governance participation and staking for fee-linked rewards through the xORCA system. Its relevance and demand depend on continued use of the Orca protocol, sustained trading volume, active governance participation, and the maintenance of the xORCA staking and buyback mechanism. A material decline in protocol activity, trading volume, or governance engagement would reduce the practical utility of ORCA.

Fixed supply and treasury-distribution risk

ORCA has a stated fixed total supply of 75million tokens. Community governance proposals may direct treasury ORCA allocations toward grants, development, or other purposes. Such treasury movements can affect circulating supply, market expectations, and perceived token scarcity. The community treasury wallet addresses are publicly disclosed and can be monitored on-chain.

xORCA staking liquidity and redemption risk

Staking ORCA creates a seven-day cooldown before redemption is complete. During this period, a Claim Ticket non-fungible token is issued to represent the pending claim, and the redemption rate is locked at the moment of initiation. ORCA staked in the xORCA vault is subject to smart-contract risk for the duration of the staking period. Stakers cannot access their underlying ORCA immediately in the event of adverse market conditions during the cooldown.

Public-ledger transparency risk

ORCA transfers, swap activity, liquidity positions, staking transactions, and associated wallet addresses are permanently and publicly recorded on Solana. These records can be analysed, combined with other data sources, and used to infer user activity patterns or identify participants. This is an inherent characteristic of public blockchain infrastructure and cannot be mitigated at the protocol level.

Token price and market manipulation risk

ORCA market prices can move rapidly due to market conditions, regulatory developments, security events, sentiment changes, or deliberate manipulation by market participants. Crypto-asset markets may be susceptible to wash trading, spoofing, pump-and-dump activity, and other abusive practices across decentralised and centralised trading venues, which can cause material and rapid price movements.

I.4 Project implementation-related risks

Proposal implementation and delivery risk

Governance proposals must pass through community discussion, feasibility review, voting, and implementation stages. Delivery depends on proposal quality, implementer capacity, participation levels, technical feasibility, and adherence to milestones. Proposals that are approved may nonetheless be delayed, modified, or not fully implemented if implementation conditions change after voting.

Governance participation risk

On-chain voting requires a minimum participation threshold and is weighted by token holdings. Low voter turnout, apathy, or disengagement by token holders may result in proposals passing without representative community support, or may prevent quorum from being reached. Participation is not mandatory and cannot be compelled.

Third-party interface and wallet dependency

Users access the Orca protocol through third-party wallets, interfaces, and RPC providers not controlled by Orca. Outages, policy changes, geographic restrictions, or discontinuation of these services can impair access to protocol functions, affect the ability to submit transactions, and disrupt asset management.

Treasury and funding dependency

Protocol development, grants, and operational activities depend on funds held in the Orca Fee Treasury and Community ORCA Treasury. Ineffective treasury management, governance disputes over allocation, or depletion of treasury resources could constrain development capacity, ecosystem grants, and implementation timelines.

Data handling and privacy risk

Orca collects wallet addresses, device data, usage behaviour, transaction history, and communications data through the site and via third-party service providers. This data may be shared with vendors, analytics providers, affiliates, and public authorities, and may be transferred to jurisdictions outside of users' home countries. Users have limited ability to prevent collection of on-chain transaction data, which is inherently public.

Jurisdiction and dispute-resolution complexity

Orca Management Company S.A. is a Panama corporation. Arbitration under the Orca Terms of Use is subject to applicable law selected under those terms. Multi-jurisdictional legal arrangements may complicate user recourse, regulatory engagement, and the enforceability of dispute outcomes across different legal systems.

RPC and API dependency

Orca software development kits require an active RPC endpoint to communicate with the Solana network. The Orca REST API provides pool data, protocol metrics, and token information that integrators and users rely on. Degradation or unavailability of RPC providers, indexers, or Orca API services can affect state visibility, integration reliability, and user decision-making.

Service continuity and force-majeure risk

Access to the Orca interface or related services may be suspended, restricted, or terminated due to system failures, adverse events, regulatory action, natural disasters, or other emergencies. Such disruptions can interrupt access to protocol functions without advance notice.

Community governance and vote concentration

The Orca protocol is governed by ORCA and xORCA token holders, with voting weight proportional to token holdings. Concentrated holdings or coordinated voting blocs may exert disproportionate influence over proposals affecting fee structures, treasury allocation, protocol upgrades, and governance changes. Delegated voting power may further concentrate effective voting authority.

DAO Council execution and operational discretion

The DAO Council executes approved governance decisions and manages day-to-day protocol operations, including emergency responses and parameter adjustments. Operational failures, coordination gaps, or incorrect Council execution could affect protocol maintenance, incident response, or the implementation of approved community decisions. The Council operates within community-defined limits and is subject to replacement by community vote, but this oversight is itself subject to governance participation levels.

xORCA administrative control risk

The xORCA staking system includes a 3-of-5 multisig requirement for program changes and an emergency pause capability. Compromise of a sufficient number of signing keys or misuse of the pause function could affect staking operations, fee-buyback execution, or user access to governance participation through xORCA. User ORCA redemptions are stated to remain available during a pause

I.5 Technology-related risks

Smart-contract and concentrated liquidity logic risk

ORCA and the Whirlpool protocol depend on Rust smart contracts deployed on Solana. Whirlpools use concentrated liquidity, meaning execution quality depends on whether active liquidity exists within the relevant price range at the time of a swap. In the absence of in-range liquidity, swaps may fail or result in high slippage. Adaptive fees can increase automatically during periods of elevated price volatility, raising transaction costs for users. Defects in smart-contract logic, SDK implementations, or fee calculations could cause incorrect execution, fund inaccessibility, or unintended pool behaviour.

Solana Layer-1 dependency

ORCA and all Whirlpools operations depend entirely on Solana's network for transaction inclusion, ordering, and finality. Solana network congestion, validator outages, protocol-level bugs, or extended downtime would prevent ORCA transfers, Whirlpool interactions, staking, and governance participation. Priority fees, compute-unit constraints, and failed-transaction fee deductions are inherent to the Solana fee model and affect all ORCA-related activity.

SPL token infrastructure dependency

ORCA is issued as an SPL token and its transferability depends on the correct operation of Solana's Token program, associated token accounts, and account rent mechanics. Users must hold a compatible Solana wallet with sufficient SOL to cover account rent and transaction fees. Errors in token account setup, signing authority, or associated token account derivation can prevent receipt or transfer of ORCA.

Whirlpools configuration and fee-authority risk

WhirlpoolsConfig and FeeTier accounts define fee rates, tick spacing, and collection authorities for pools. Misconfiguration or compromise of these authorities could affect pool-level fee settings, protocol-fee collection, or supported pool parameters. The program-only vault withdrawal restriction limits the scope of this risk to configuration and fee parameters rather than pooled liquidity directly.

TokenExtensions compatibility risk

Certain Solana Token-2022 extensions can introduce elevated risk to pool operations and user outcomes. Tokens bearing such extensions require a TokenBadge issued by the TokenBadge authority before they can be used for Whirlpool pool initialisation. Errors in TokenBadge issuance, or the introduction of new extension types that are not yet covered by the badge mechanism, could affect pool safety or expose users to unexpected token behaviour.

xORCA contract and emergency-control risk

ORCA staked into the xORCA vault is held in smart contracts. Contract defects, compromise of the 3-of-5 multisig signer set, or misuse of the emergency pause capability could affect staking operations, fee-buyback execution, or user access to pending redemptions. While withdrawals are stated to remain available during a pause, the interaction between the pause mechanism and in-progress redemption Claim Tickets is a source of residual risk.

Vault-withdrawal and custody-boundary risk

Whirlpool vault assets can only be withdrawn through the execution of the Whirlpool program itself. No party, including the program owner and the WhirlpoolsConfig owner, can withdraw vault assets directly. Users remain exposed to correct program execution and to the distinction between assets held within program-controlled vaults and assets held in individual wallets. Any defect in program withdrawal logic could affect liquidity provider access to pooled assets.

Quantum computing risk

Solana uses the Ed25519 elliptic-curve signature scheme for all transaction authentication. A cryptographically relevant quantum computer capable of running Shor's algorithm could in principle derive private keys from their corresponding public keys, compromising the security of ORCA token accounts and all Solana-based key pairs. program-derived addresses, which rely on SHA-256-based hashing, carry greater resistance to quantum attack under Grover's algorithm but are not immune. No quantum computer currently capable of executing these attacks at a cryptographically relevant scale exists, and the timeline for such capability is uncertain. The National Institute of Standards and Technology finalised its first post-quantum cryptography standards in August 2024, recognising the long-term threat to elliptic-curve-based systems. Solana has not published a post-quantum migration roadmap, meaning any migration would depend on future community and validator coordination that has not yet been defined.

I.6 Mitigation measures

Offer-Related Risks

  • Market price volatility and liquidity: Pool-level liquidity, TVL, token balances, fee rates, and adaptive-fee status are available in real time through the Orca Whirlpools REST API, allowing users and integrators to assess pool conditions and available depth before executing transactions.
  • Access and interface dependency: The Whirlpools program is permissionless and accessible via any Solana-compatible RPC endpoint and wallet, independently of the official Orca interface. Interaction does not require use of the Orca front end; the open-source Whirlpools SDK can be configured against any valid RPC URL.

Issuer-Related Risks

  • Whirlpools configuration authority risk: The Whirlpool program enforces in its on-chain logic that vault assets can only be withdrawn through program-controlled execution. This constraint is not overridable by the WhirlpoolsConfig owner or the program deployer, and is independently verifiable in the open-source contract code at github.com/orca-so/whirlpools.

Crypto-Asset-Related Risks

  • Fixed supply and treasury-distribution risk: The ORCA total supply of 75 million tokens is recorded in the on-chain mint account at address orcaEKTdK7LKz57vaAYr9QeNsVEPfiu6QeMU1kektZE and is verifiable by any party on Solana Explorer without reliance on issuer representations.
  • xORCA staking liquidity and redemption risk: Upon initiating unstaking, the applicable xORCA-to-ORCA exchange rate is locked at the moment of redemption initiation and recorded in the Claim Ticket non-fungible token issued to the user. This prevents exchange rate deterioration from affecting the redeemable ORCA amount during the seven-day cooldown period.

Project Implementation-Related Risks

  • Proposal implementation and delivery risk: Governance proposal templates require implementer identification, milestone definition, risk and consideration sections, and DAO Council feasibility review before a proposal proceeds to on-chain voting. This structure creates a documented accountability framework tied to each approved change.
  • Treasury and funding dependency: The Orca Fee Treasury, Community ORCA Treasury, Climate Fund wallet, and undistributed-fee wallet addresses are publicly disclosed and monitorable on-chain, allowing token holders and the public to observe treasury balances and movements without reliance on issuer reporting.
  • Governance participation risk: A minimum participation threshold is applied to on-chain votes, and proposals must pass through a mandatory community discussion period on the Orca governance forum before voting opens. These requirements prevent low-participation outcomes from being produced by a small number of votes.
  • RPC and API dependency: The Orca software development kit accepts a configurable RPC URL, allowing integrators and users to substitute their own RPC provider or use any public Solana RPC endpoint, reducing dependence on any single infrastructure provider for transaction submission.
  • Community governance and vote concentration: ORCA and xORCA holders may delegate voting power to any address of their choosing, distributing governance influence beyond direct token holdings. Voting and proposal activity occur on the publicly auditable Realms platform at realms.today/dao/ORCA, where all submissions, votes, and outcomes are verifiable on-chain. The DAO Council is subject to removal by community vote at any time.
  • DAO Council execution and operational discretion: Council powers are bounded by community-approved limits; actions outside those bounds require full governance approval. Decision logs, meeting notes, and operational communications are published through the Orca governance forum at gov.orca.so, maintaining a public record of Council activity against which departures from mandate can be identified.
  • xORCA administrative control risk: Program changes to the xORCA system require approval from at least three of five designated multisig signers, distributing change-management authority and making unilateral modification by a single party impossible. User redemptions are stated to remain accessible during an emergency pause.

Technology-Related Risks

  • Smart-contract and concentrated liquidity logic risk: The Whirlpools program has undergone eight independent security audits by Kudelski Security, Neodyme, OtterSec, and Sec3 between January 2022 and January 2026. The program is deployed using a verifiable build that allows any party to independently confirm that the on-chain executable matches the published source code. An active bug bounty program on Immunefi offers rewards of up to USD 500,000 for qualifying vulnerability disclosures against deployed Orca contracts.
  • TokenExtensions compatibility risk: Tokens bearing Token-2022 extensions that pose elevated risk to pool operations require a TokenBadge issued by the designated authority before they can be used to initialise a Whirlpool. This on-chain gating mechanism is enforced by the Whirlpools program logic and prevents pools from being created with tokens carrying potentially harmful extensions without explicit authorisation.
  • Vault-withdrawal and custody-boundary risk: The program-only vault withdrawal restriction is implemented in the open-source Whirlpools contract and is enforceable exclusively through Whirlpool program execution. This structural constraint is independently auditable in the published source code and has been confirmed across multiple independent security reviews.

S.4 Consensus Mechanism

ORCA, as an SPL token on Solana, inherits Solana's network-level consensus for all token transfers and Whirlpools program executions. Ordering and finality are determined entirely by Solana's validator network.

Solana generates a source of time through a Verifiable Delay Function known as Proof of History. Time is divided into slots, each with a designated leader elected from the active validator set. The leader produces a block for each slot, and validators communicate their fork preference through signed votes identifying the validator and the block being voted for. The leader schedule is recalculated at epoch boundaries, with each validator updating its own root fork and leader schedule each time the slot height crosses an epoch boundary.

Tower BFT augments the voting system with lockouts. When a validator votes on a fork, a lockout is imposed for a number of slots during which the validator cannot switch to a non-descendant fork without forfeiting that commitment. Lockouts increase in duration exponentially with each successive vote on the same fork, making rollback of deeply confirmed forks progressively more costly. Validators that violate lockouts by voting for a diverging fork within the lockout window are subject to slashing, where the concurrent vote can be proven to the cluster.
