| 08 | Characteristics of the crypto-asset |
SKY is a crypto-asset used within the Sky Protocol, a decentralised blockchain-based financial system that evolved from the MakerDAO ecosystem. The Sky Protocol operates on the Ethereum Blockchain and provides infrastructure for decentralised governance and on-chain financial mechanisms. SKY primarily functions as a governance crypto-asset. Holders of SKY may participate in governance processes relating to the operation, parameters and evolution of the Sky Protocol. Governance participation is typically exercised through voting mechanisms in accordance with the rules and procedures defined by the protocol. Participation in governance may require holders to stake or otherwise commit their SKY holdings in line with the applicable governance framework. In addition to governance participation, SKY may be used within ecosystem mechanisms, including staking, incentive programmes and other protocol modules made available through the Sky Protocol. The availability and conditions of such mechanisms are determined by the protocol rules and may change over time. Holding SKY does not confer ownership, profit participation, repayment or redemption rights against a central issuer. SKY does not represent a claim on assets or revenues and does not provide holders with a guaranteed right to compensation or value protection. The value of SKY is determined by market conditions and may fluctuate. |

| D.4 | Crypto-asset project description |
Sky Protocol is a decentralised blockchain-based on Ethereum, a financial system that evolved from the MakerDAO ecosystem. The project provides infrastructure for decentralised governance and on-chain financial mechanisms, including stablecoin-related functionality, staking and incentive modules. Sky Protocol operates through smart contracts on distributed ledger technology and is governed by its community through a governance framework that enables holders of the SKY crypto-asset to participate in decisions relating to the protocol’s operation and evolution. The Sky Protocol consists of software code deployed on the Ethereum blockchain, designed to enable the Sky Ecosystem to operate autonomously and allow users to interact directly with blockchain-based infrastructure. It is built from self-executing smart contracts that are trustless, decentralised, and permissionless. These smart contracts embed the rules and agreements that form the foundation of the Sky Protocol, enabling the efficient creation, transfer, and verification of digital assets, as well as supporting Sky Ecosystem governance. The Sky Protocol hosts multiple assets including USDS, DAI, sUSDS, stUSDS, SKY, and MKR as well as core components such as the Sky Savings Rate, Sky Token Rewards, the Staking Engine, specialised Expert Modules, and other supporting infrastructure. At its core, the protocol uses overcollateralised vaults to back stablecoins such as USDS (the upgraded stablecoin successor to DAI) and DAI itself. Users deposit approved collateral into these vaults to generate stablecoins, with the system maintaining an over-collateralisation requirement to support stability and solvency. Sky was one of the early DeFi protocols to introduce RWAs into a stablecoin system, allowing tokenised real-world financial instruments such as bonds, real estate linked tokens, and other off-chain assets to be used as backing for stablecoin issuance and generate yield. These RWA Vaults differ from traditional on-chain crypto vaults in that they require legal frameworks, off-chain valuation mechanisms, and governance oversight to tokenise and manage such assets. USDS is an ERC-20 stablecoin token in the Sky ecosystem, and the protocol provides a DAI–USDS converter that facilitates 1:1 conversions between DAI and USDS via supported interfaces. SKY, the governance token of the Sky Protocol, to which MKR may be upgraded at a fixed ratio of 1 MKR to 24 thousand SKY (subject to the Delayed Upgrade Penalty as applicable. It implements an on-chain governance framework through which token holders can vote on protocol decisions and implement changes through smart-contract execution, and ecosystem applications and interfaces, including Sky.money as a non-custodial interface for upgrades and for access to protocol features such as the Sky Savings Rate (SSR) and Sky Token Rewards. |

| D.8 | Description of past milestones |
Past Milestones: From 2017 to 2023, MakerDAO launches and operates as a decentralised protocol governing the DAI stablecoin. MKR functions as the governance crypto-asset for protocol decisions, risk parameters and system upgrades. Over this period, MakerDAO developed large-scale on-chain financial infrastructure and decentralised governance mechanisms. From 2022 to 2023, MakerDAO governance discussions introduce the long-term “Endgame” framework, outlining a future transition to a new protocol structure, governance model and token architecture. Governance proposals begin laying the groundwork for a protocol rebrand and token evolution. August 2024, the Sky Protocol is formally introduced as the successor framework to MakerDAO. SKY is introduced as the new governance crypto-asset, replacing MKR. A protocol-level upgrade mechanism is made available allowing MKR holders to convert MKR into SKY at a predefined ratio. Governance transitions to the Sky Protocol framework, while maintaining continuity of on-chain financial infrastructure. Late 2024, governance processes continue under the Sky Protocol structure. SKY holders participate in protocol governance, parameter adjustments and ecosystem decisions. Stablecoin-related functionality (USDS), savings mechanisms and incentive modules remain operational within the new protocol framework. The migration announcement was completed on 2 May 2025, when an official post detailing the SKY migration was published on the Atlas forum and the migration was publicly announced in detail. The governance poll was completed on 12 May 2025, enabling all MKR holders to participate in the governance poll. Communications was completed on 13 May 2025, with the launch of a community-wide marketing campaign for the Sky Ecosystem. Spell Publication was completed on 15 May 2025, when the governance upgrade spell was published for community review. Migration Go-Live took place on 19 May 2025 when the governance upgrade spell was executed. Staking Rewards Activation was completed on 29 May 2025, with the publication of the spell activating USDS rewards for the Staking Engine. Delayed Upgrade Penalty Kick-Off was scheduled for 18 September 2025. From that date, a Delayed Upgrade Penalty applied to all MKR not upgraded to SKY before 18 September. As soon as the penalty took effect, a 1% penalty was applied to MKR-to-SKY upgrades, increasing by an additional 1% every three months thereafter. Penalty Ramp-Up commenced in December 2025 and continues on an ongoing basis, with the delayed upgrade penalty increasing by a further 1% every three months unless Sky Governance determines otherwise. |
||||||||
| D.8 | Description of future milestones |
Future Milestones: Future developments are expected to occur through governance-driven upgrades. Potential areas of evolution include governance refinement, incentive mechanisms, protocol modules and infrastructure integrations. |
||||||||
| D.9 | Resource allocation |
Protocol resources (including protocol-controlled assets, surplus, and flows) are publicly tracked through Sky’s treasury and surplus reporting dashboards and are allocated through governance processes implemented via on-chain voting and smart-contract execution (including executive votes/spells approving treasury management actions, funding transfers, compensation, and system-surplus mechanisms such as Smart Burn Engine parameterisation). The Sky Ecosystem allocates protocol surplus as part of its resource management strategy through an on-chain buyback mechanism powered by the Smart Burn Engine. These buyback activities constitute a governance-directed allocation of protocol surplus resources and are subject to change by Sky Governance. All figures are variable, model-based, and not guaranteed. As of the date of this white paper, the protocol has utilised approximately 112.28 million USDS in surplus revenues to repurchase approximately 1.79 billion SKY, representing around 6.95% of the circulating supply of USDS. Supply allocation data indicates that approximately 67.43% of total SKY (15.82 billion) is staked (circulating but locked), 19.95% (4.68 billion) is circulating and otherwise classified, 9.91% (2.32 billion) remains circulating but not migrated, 1.8% (422.43 million) is held in treasury as non-circulating supply, and approximately 0.91% (213.51 million) falls within other categories. |
||||||||
| D.10 | Planned use of Collected funds or crypto-Assets |
Ongoing and future protocol surplus revenues are expected to follow the established governance framework and may be allocated to buybacks in accordance with the existing mechanism. No other funds are planned to be raised or implemented in connection with this crypto-asset, as no offer to the public is intended. |

| F.1 | Crypto-asset type | Crypto-assets other than asset-referenced tokens or e-money tokens |
| F.2 | Crypto-asset functionality |
The primary functionality of SKY is governance participation. Holders of SKY may participate in the Sky Protocol’s governance processes, including voting on proposals relating to protocol parameters, system upgrades, risk management frameworks and ecosystem development. Governance participation is exercised in accordance with the protocol’s governance rules and procedures and may require holders to stake or delegate their SKY holdings as specified by the governance framework in force at the relevant time. SKY is also used within protocol-level economic and incentive mechanisms, including staking-based participation and reward structures made available through the Sky Protocol. These mechanisms are designed to support protocol operation and governance participation rather than to provide access to a discrete good or service supplied by a central issuer. The Sky Protocol incorporates mechanisms for managing both surplus and deficit within its stablecoin system. Excess stablecoin proceeds including net revenue and stability fees may accumulate in the protocol’s internal buffer. When the buffer exceeds a governance determined threshold, surplus stablecoins are put into surplus auctions, where they are exchanged for SKY governance tokens that are subsequently removed from circulation, thereby helping to balance overall economic conditions within the protocol. Conversely, if the protocol incurs uncovered debt that cannot be covered by available surplus, debt auctions may be triggered, in which newly minted governance tokens are sold for stablecoins to recapitalise the system. These auction-based mechanisms surplus auctions to retire governance tokens and debt auctions to address shortfalls form core elements of the protocol’s financial stability framework, directly supporting the integrity of the stablecoin and broader ecosystem operations. USDS is the native stablecoin of the Sky Protocol., and governance decisions taken by SKY holders may influence parameters and mechanisms relating to stablecoin operation, savings modules and other on-chain financial components of the ecosystem. |
| F.3 | Planned application of functionalities | Not applicable |
| F.4 | Type of crypto-asset white paper | |
| F.5 | The type of submission | |
| F.6 | Crypto-asset characteristics |
SKY is a fungible crypto-asset that is transferable between compatible blockchain addresses without the involvement of a central intermediary. It does not represent ownership, equity, a claim on assets or revenues, nor does it confer any right to repayment or redemption against a central issuer. The primary characteristic of SKY is its governance function. Holders of SKY may participate in governance processes relating to the operation, parameters and evolution of the Sky Protocol, subject to the applicable governance rules and procedures. Governance participation may require delegation, staking or other procedural steps defined by the protocol at the relevant time. MakerDAO rebranded to Sky in 2024 and introduced SKY as the new native governance token. MKR and SKY coexist, with conversion available from MKR to SKY. Sky Ecosystem governance has been transitioning governance from MKR to SKY, with SKY becoming the governance token for on-chain voting on the new governance system. The protocol conversion rate is 1 MKR to 24 thousand SKY. However, governance can apply a Delayed Upgrade Penalty over time that reduces the net SKY received for later upgrades. |

| H.1 | Distributed ledger technology | N/A as DTI is provided in F.13 |
| H.2 | Protocols and technical standards |
Networking layer Ethereum operates a permissionless peer-to-peer network using DevP2P protocol suite for node communication. Nodes discover peers through discv5 (discovery version 5), implementing Kademlia-based distributed hash table for decentralised peer location without central coordination. Full nodes maintain connections to approximately 50-100 peers, propagating transactions and blocks through gossip protocols ensuring network-wide distribution within seconds. Transaction Propagation User-signed SKY transactions broadcast from wallet software reach connected Ethereum nodes entering local mempools (pending transaction pools). Nodes validate transaction signatures, nonce sequencing, and gas parameters before relaying to peers. Gossip propagation ensures transaction distribution across the network, reaching validator mempools where they await inclusion in proposed blocks. Transaction replacement follows EIP-1559 priority fee mechanics, with higher-fee transactions displacing lower-fee equivalents in resource-constrained mempools. Interface Layer Non-custodial interfaces such as sky.money serve as transaction construction interfaces, submitting signed transactions to the Ethereum network without holding user funds or operating intermediary infrastructure. SkyLink components facilitate asset bridging between Ethereum mainnet and layer-2 networks including Base, Arbitrum, Optimism and Unichain, maintaining canonical state records on mainnet while enabling cross-chain interoperability. Application layer The application layer implements protocol functionality through interconnected smart contract modules:

| H.3 | Technology used |
Execution environment SKY operates within the Ethereum Virtual Machine executing Solidity-compiled bytecode at contract address 0x56072C95FAA701256059aa122697B133aDEd9279. Transaction validation occurs through Ethereum validator clients (Geth, Nethermind, Besu, Erigon) with gas metering constraining computational resources. Core software components The protocol employs modular smart contract architecture. Vat contract provides central accounting, tracking collateralised positions through normalised debt (art) and collateral units (ink) with 18-decimal precision. Fee accrual operates via rate accumulation variables, calculating stability fees as time-weighted obligations. Collateral handling coordinates across Vat (accounting), Spot (collateralisation enforcement), and Clipper (auction execution) modules. Chief aggregates voting weight through SKY token deposits, implementing continuous approval voting. Pause enforces mandatory time delays on governance actions. Spell contracts execute parameter changes as atomic bundles. Smart Burn Engine coordinates surplus auctions with automated token destruction. Wallet technologies SKY requires standard Ethereum wallets supporting ERC-20 interactions and contract calls. Non-custodial implementations (MetaMask, Ledger, Trezor) enable direct protocol access. SKY implements EIP-2612 permit for gasless approvals via off-chain signatures and EIP-1271 for smart contract wallet authorisation. Protocol interactions (Lockstake staking, VoteDelegate delegation, farming rewards) execute through wallet-initiated contract calls creating non-custodial positions owned by user addresses. Key management Users maintain exclusive private key control with no issuer-managed keys or custodial solutions. Private keys generate Ethereum addresses via ECDSA (secp256k1) public key derivation and Keccak-256 hashing. Hardware wallets isolate keys in security chips requiring physical confirmation. Software wallets encrypt key material using passwords or biometrics. BIP-39 seed phrases enable cross-wallet recovery. Multi-signature and account abstraction (ERC-4337) support distributed control and programmable authorisation while maintaining non-custodial architecture. Oracle infrastructure Price feed oracles supply collateral valuations with Oracle Security Module enforcing one-hour delay before activation, mitigating flash crashes and manipulation. Governance-selected providers push updates to OSM storage. Emergency oracles can freeze compromised feeds and initiate global settlement. Keeper infrastructure Independent economic actors monitor vault ratios triggering liquidations when undercollateralised, and surplus levels initiating auctions when reserves exceed buffers. Keepers operate without protocol infrastructure, incentivised through liquidation penalties and auction participation. Supporting systems Protocol interfaces with Ethereum's peer-to-peer network for transaction propagation. IPFS hosts governance documentation via content-addressing. SkyLink bridges coordinate cross-chain transfers to Base, Arbitrum, Optimism, and Unichain through lock-and-mint mechanisms. |
| H.4 | Consensus Mechanism |
Ethereum's proof-of-stake consensus secures all SKY protocol state transitions. Validators deposit 32 ETH into the Ethereum staking contract, gaining block proposal privileges and attestation responsibilities. Time progresses in 12-second slots aggregated into 32-slot epochs. Each slot features one randomly selected proposer and a validator committee providing attestations. Validators deterministically order transactions within proposed blocks based on priority fee bidding and position within mempool queues. This ordering mechanism ensures consistent execution sequence for interdependent SKY operations, preventing front-running of governance votes. This is achieved through transaction reordering and maintaining fairness in liquidation auctions where multiple keepers compete for collateral. Block proposals occur every 12 seconds, with validators randomly selected via RANDAO, distributing proposal opportunities across the validator set and preventing predictable censorship windows. SKY transfers, Chief voting weight updates, and vault state modifications execute in their included block's sequence, with finalisation guaranteeing irreversible ordering after checkpoint epochs. Finality derives from checkpoint-based voting: when two checkpoint epochs form a supermajority link (votes representing ≥66.67% of total staked ETH), all transactions in the finalised epoch become irreversible. Reverting finalised blocks requires destroying substantial validator stake through slashing mechanisms, creating economic barriers to chain reorganisation attacks. SKY transfers, mint/burn operations and governance executions inherit Ethereum's finality guarantees. Once transactions settle in finalised blocks, state changes become economically irreversible, backed by the aggregate value of staked ETH securing the network. |
| H.5 | Incentive Mechanisms and Applicable Fees |
Network-level fees All Ethereum transactions incur gas fees denominated in ETH, calculated as gas_used × gas_price. Users pay gas fees for SKY transfers, MKR-to-SKY conversions, vault operations and governance votes. These fees compensate validators for block inclusion and execution, flowing entirely to Ethereum network participants rather than Sky Protocol. SkyLink bridging operations between the Ethereum mainnet and layer-2 networks (Base, Arbitrum, Optimism, Unichain) involve separate fee structures depending on the target network's gas model and bridge architecture.

| I.1 | Offer-related risks |
Market price volatility and valuation risk SKY may experience material price volatility, including abrupt price changes that are not correlated with protocol fundamentals. This risk is amplified during the MKR-to-SKY transition, as liquidity and price discovery shift across venues and routes. Liquidity and conversion-route concentration risk Secondary-market liquidity for the SKY token may be limited or fragmented across various platforms and venues. During transition from MKR to SKY, the Converter contract could be viewed as the most reliable route for converting MKR to SKY. This preference may lead to effective liquidity concentrating in this single on-chain contract, potentially amplifying certain market dynamics or execution risks for users. Trading and access restriction risk SKY token trading and liquidity access rely on external platforms, including decentralised exchanges, centralised exchanges, DEX aggregators, and web-based front-end interfaces who implement their own operational policies and jurisdictional restrictions, policy changes, or delisting decisions. Lack of Intrinsic Value The token does not possess inherent utility, functioning solely as a speculative asset. Its valuation is predominantly influenced by community engagement, speculative activities, and overall market sentiment, which presents considerable challenges to sustaining long-term value stability. Delisting Risks Bitstamp Europe S.A. might remove the token from trading in line with Bitstamp Markets Trading Rules. |
| I.2 | Issuer-related risks | Not applicable, as SKY does not have an identifiable issuer under MiCA; SKY tokens are generated and governed through a fully decentralised, permissionless smart contract protocol on Ethereum, with no centralised legal entity controlling issuance or distribution. |
| I.3 | Crypto-assets-related risks |
Token contract privileged-role risk The SKY token contract is controlled by “wards” with privileged access, including the ability to add/remove wards and mint SKY. Compromise or misuse of privileged access could affect supply and holder interests. Transaction finality and execution risk SKY transfers and interactions occur on Ethereum and are therefore subject to congestion, fee volatility, execution delays/failures, and other network conditions. Converter mechanics and rounding risk The bidirectional conversion path uses a fixed rate, and the SKY-to-MKR path rounds down when the SKY amount is not a multiple of the rate, which can result in small conversion losses. Allowance/signature validation risk SKY supports permit-based approvals and EIP-1271 contract signature validation. User error or integration mistakes in approval/signature flows can lead to unintended approvals or failed transactions. Transfer restriction edge-case risk The audited design of SKY includes restrictions such as disallowing transfers to the zero address or to the token contract itself, which may cause unexpected transfer failures for some operational workflows. Scams Due to the irreversible execution of blockchain transactions and the limited ability to identify counterparties in decentralised environments, crypto-asset markets are particularly exposed to fraudulent activity. Once assets are transferred, recovery is typically not possible. Investors should therefore exercise heightened caution when acquiring or transferring crypto-assets. Fraudulent schemes may include, among others, the issuance of counterfeit tokens bearing similar names, phishing attempts via email or social media, fake promotions or airdrops, and impersonation or identity theft. Market Abuse Crypto-asset markets may be particularly vulnerable to market abuse due to the characteristics of the underlying blockchain infrastructure and the fragmented nature of trading across platforms and jurisdictions. Practices such as front-running, spoofing, pump-and-dump schemes, wash trading, and other forms of manipulation may occur across different systems, trading venues, or geographic locations. These risks may be amplified for crypto-assets with low market capitalisation, limited liquidity, or a small number of trading venues. Such conditions can increase price volatility and susceptibility to manipulation, potentially resulting in significant losses, including the total loss of the invested funds |
| I.4 | Project implementation-related risks |
Migration and upgrade execution risk Integrators are required to support both MKR and SKY during transition, highlighting operational steps and timelines. Failures or delays by integrators (wallets, DEXes, exchanges, lending protocols) may cause user disruption and liquidity issues. Dependency and third-party service provider risk Availability depends on third-party service providers and vendors; outages or failures can degrade or interrupt access to protocol interactions through the official interface. Third-party subdomain / ecosystem site risk Certain sky.money subdomains accessible through the interface are controlled by independent third parties and may have different governing terms. This can create user confusion and inconsistent risk controls. |
| I.5 | Technology-related risks |
Smart contract vulnerability risk Sky’s codebases have undergone multiple audits, but both the audit summary and the audit report emphasise that audits are time-boxed and cannot uncover all vulnerabilities; exploitation could cause loss of assets or protocol malfunction. Governance-module technical risk The Pause design relies on scheduled plans, delegatecall via proxy, and constraints (plot/exec/drop); flaws in these invariants or misconfiguration could enable harmful governance actions or prevent corrective action. Oracle and external data risk Oracle failures, including price data manipulation, incorrect valuations, delayed updates, or complete feed downtime, may directly compromise vault safety calculations and liquidation trigger thresholds. Malfunctioning oracles can cause premature liquidations during flash crashes, delayed liquidations allowing protocol undercollateralisation, or incorrect collateral ratio calculations enabling unauthorised USDS generation against insufficient backing. Front-end integrity / phishing and signing risk Interface compromises may attempt to trick users into signing malicious transactions or display incorrect information; users remain responsible for wallet security and signing decisions. Bug bounty scope limitation risk The bug bounty is managed by Immunefi and is subject to its scope and rules; exclusions or scope gaps may leave some issues undiscovered by the programme. |
