| 08 | Characteristics of the crypto-asset |
ZK is the native crypto-asset of the zkSync network, a settlement network designed to provide privacy, institutional control, cryptographic enforcement, and Ethereum finality. The total maximum supply is fixed at 21,000,000,000 tokens, with no inflation. Tokens are distributed through capped minters rather than a pre-minted treasury. ZK powers governance and is designed with a flexible structure whereby governance may expand its economic function as the network evolves. Holders may participate in governance by voting on protocol upgrades, fee structures, and economic parameters. Governance is conducted through a three-body model comprising the Token Assembly (holder voting), the Security Council (technical review of upgrades), and the Guardians (emergency safeguard). No single body controls the protocol. ZK is used for protocol fees across the zkSync network. Institutional transactions within the Prividium architecture use ZK for protocol fees, which are routed according to governance-defined mechanisms. |

| D.4 | Crypto-asset project description |
The zkSync project is focused on the development of a Layer-2 blockchain network built on Ethereum, designed to improve scalability and efficiency through the use of zero-knowledge proof technology. The network operates as a validity rollup, where transactions are processed off-chain and subsequently verified and settled on the Ethereum mainnet. The project includes zkSync Era, which provides an execution environment compatible with Ethereum, enabling the deployment of decentralised applications while benefiting from reduced transaction costs and increased throughput. Transactions processed within the network are aggregated and validated using cryptographic proofs before being submitted to Ethereum for final settlement. In addition, the project encompasses the development of the ZK Stack, a framework that enables the deployment of independent, interoperable chains based on the same underlying zero-knowledge technology. These chains may operate with their own configurations while remaining connected through a shared settlement layer, enabling interoperability and coordination across the broader zkSync ecosystem. The zkSync network is designed to support advanced use cases, including institutional applications, through architectures such as segregated execution environments that allow for controlled access and privacy while maintaining settlement guarantees on Ethereum. The project also includes governance frameworks and supporting infrastructure to enable decentralised decision-making in relation to protocol upgrades, parameter adjustments, and ecosystem development. The network is intended to evolve over time through protocol improvements and governance processes. |

| D.8 | Description of past milestones |
Past milestones The concept of zk-rollups as a general-purpose scaling solution for Ethereum was introduced by Matter Labs in 2019, forming the technical foundation of the project. This was followed in June 2020 by the deployment of the first version of the network (later referred to as zkSync Lite), which enabled payments, token transfers and limited non-fungible token functionality using zero-knowledge rollup technology. Subsequent development focused on expanding functionality towards general-purpose computation. After an initial testing phase beginning in 2021, zkSync Era, a zkEVM-compatible system, was introduced in a restricted mainnet environment in 2022 and later made publicly available to developers in 2023, enabling permissionless deployment of smart contracts. The zkSync architecture has also evolved to support modular scaling through frameworks such as the ZK Stack, which enables the deployment of interoperable chains based on zero-knowledge technology. During 2023, the project introduced an updated proof system known as Boojum, designed to improve efficiency and reduce hardware requirements for proof generation, thereby facilitating broader participation in the network’s validation processes. In 2024, development efforts included research and initial implementation steps towards decentralising the proving infrastructure, including collaboration with external contributors. In June 2024, the native token was launched and distributed through a claim process via minting contracts. In September 2024, a governance framework was activated, comprising multiple bodies responsible for decision-making and protocol oversight. During 2025, further developments were implemented. A pilot phase of a decentralised prover network was introduced, enabling external participants to contribute to proof generation in a testing environment. Protocol upgrades also introduced compatibility with Ethereum Virtual Machine bytecode execution through an interpreter mechanism. Additional infrastructure components were deployed, including a coordination and aggregation layer for cross-chain transactions (referred to as zkSync Gateway), as well as infrastructure supporting private or permissioned blockchain environments. The project also continued work on proof system design and performance improvements, including exploration of alternative architectures. |
||||||||||||||||||||||||||||||||
| D.8 | Description of future milestones |
Future milestones As of 2026, the zkSync project has outlined further planned developments relating to the evolution of the network architecture, scalability, and decentralisation. These plans include continued work towards a fully decentralised proving infrastructure, with the objective of enabling broader participation in proof generation and reducing reliance on centralised components. The project also envisages further development of interoperable chains within the zkSync ecosystem, including expansion of the ZK Stack framework to support a network of interconnected chains with shared settlement. Additional planned developments include enhancements to cross-chain coordination and messaging infrastructure, including further development of aggregation and settlement layers designed to facilitate interaction between multiple chains and execution environments. The project also indicates continued improvements to execution environments, including compatibility and performance enhancements related to Ethereum Virtual Machine functionality. The roadmap further refers to ongoing research and development of proof systems and performance optimisation, including efforts to improve efficiency, reduce hardware requirements, and support scalability of the network. These developments are intended to contribute to the long-term evolution of the zkSync protocol and its associated ecosystem. |

| D.9 | Resource allocation |
The crypto-asset ZK has a maximum supply of 21,000,000,000 tokens. The token is deployed on the zkSync Era network and is transferable to the Ethereum mainnet. The token contract is identified by the address 0x5A7d6b2F92C77FAD6CCaBd7EE0624E64907Eaf3E. The total supply is subject to a supply cap; however, the token supply may be increased through protocol governance decisions. Not all tokens are minted at deployment. Instead, the issuance mechanism relies on “capped minters”, which are smart contracts authorised to mint tokens up to predefined limits. This mechanism enables the progressive creation of tokens rather than the immediate minting of the entire supply. At allocation, the total supply of 21,000,000,000 tokens is distributed across several categories. A portion of 29.27% (6,146,000,700 tokens) is allocated to the Token Assembly, to be distributed through governance decisions. A further 19.90% (4,179,000,000 tokens) is allocated to ecosystem initiatives administered by the zkSync Foundation. An amount of 17.50% (3,675,000,000 tokens) is allocated through a one-time airdrop without lock-up restrictions. Investors and advisors are allocated 19.78% (4,154,642,006 tokens), while 13.55% (2,845,357,294 tokens) is allocated to team members associated with Matter Labs. Token allocations to investors and team members are subject to vesting conditions over a four-year period from June 2024 to June 2028, including a one-year cliff. Following the cliff period, a portion of tokens is released initially, with subsequent tokens unlocking on a periodic basis until the end of the vesting period. The capped minter structure assigns minting rights to specific contracts corresponding to allocation categories, including the zkSync Foundation, airdrop distribution, investor allocations, and team vesting arrangements. The allocation associated with the Token Assembly is not pre-assigned to a capped minter; instead, minting rights for this portion are granted through governance decisions. This token distribution and issuance structure results in a distinction between the maximum supply defined in the protocol and the amount of tokens minted and circulating at any given time. |

The number of ZK crypto-assets in circulation may vary over time due to the token’s issuance model and distribution mechanisms. While the protocol defines a maximum supply of 21,000,000,000 tokens, not all tokens are minted at launch. Instead, tokens are created progressively through capped minter contracts, which mint tokens on a “just-in-time” basis within predefined limits. As a result, the circulating supply is lower than the maximum supply and increases over time as tokens are minted and released in accordance with allocation schedules, governance decisions, and vesting arrangements applicable to certain categories such as team members and investors. At the time of writing, the circulating supply is approximately 9755003900 ZK. |

ZK is the native crypto-asset of the zkSync network and is used in connection with governance, network operations, and protocol-level economic functions. ZK enables participation in governance. Holders may vote on network-level decisions, including protocol upgrades, fee structures, and economic parameters. Governance is implemented through a multi-body structure comprising the Token Assembly, the Security Council, and the Guardians, with decision-making processes distributed across these bodies. Decision-making authority is distributed among them, and no single body has unilateral control over the protocol. Governance processes, including proposal submission, review, and execution, are defined through formal procedures and implemented via smart contracts and associated infrastructure. These proposals may relate to protocol changes, parameter adjustments, and allocation of resources. Voting is conducted through defined procedures, and outcomes are implemented through protocol mechanisms following the applicable governance process. ZK is also used for protocol fees. Transactions within the zkSync network, including those conducted within specific execution environments, may require the payment of fees denominated in ZK. The allocation and routing of such fees are determined through governance mechanisms. |

Networking ZKsync Era is a Layer 2 zero-knowledge rollup built on Ethereum that executes transactions off-chain, aggregates them into batches and submits cryptographic validity proofs to Ethereum for settlement. ZKsync Era exposes Ethereum-compatible JSON-RPC and ZKsync-specific JSON-RPC interfaces for transaction submission, state queries and event monitoring. Submitted transactions enter the sequencer for execution and preliminary confirmation before proceeding to proof generation and Ethereum Layer 1 verification. ZKsync Era does not publicly specify its peer discovery mechanism, peer-to-peer overlay, transport encryption or session hardening rules. Serialisation ZKsync Era supports Ethereum legacy and EIP-1559 transaction formats alongside a ZKsync-specific EIP-712 typed transaction format. The ZKsync format introduces a gas-per-pubdata-byte limit, a per-byte cap on what a transaction pays for data published to Ethereum. This parameter applies to all transactions in the ZKsync Era environment, including ZK transfers, permit authorisations, voting delegation and governance interactions. Cryptography and key formats ZKsync Era uses zero-knowledge proofs to verify execution correctness on Ethereum. Accounts use secp256k1 key pairs and Keccak-256 address derivation, consistent with Ethereum. The ZK token contract additionally uses EIP-712 typed structured data signing for off-chain permit authorisations. Ledger The ZK token is maintained through smart contracts on ZKsync Era. Token state, comprising ERC-20 balances, delegated voting power and minting permissions, forms part of the ZKsync Era state, which is committed to Ethereum via state diffs. Execution ZKsync Era executes transactions in EraVM, a register-based virtual machine optimised for zero-knowledge proof generation. Ethereum smart contract bytecode is supported through an EVM Bytecode Interpreter. Privileged system contracts handle transaction processing, deployment, bridging and fee management; they may only be changed through upgrades initiated from Ethereum Layer 1. Token standards ZK is an ERC-20 governance token with EIP-2612 permit functionality and EIP-5805 voting delegation. Permit enables approvals via off-chain signed messages. Voting delegation allows a holder to assign governance voting power to any address, including themselves, whilst retaining beneficial token ownership. When tokens transfer, voting power moves between the respective delegates accordingly. The ZK token is implemented through ZkTokenV1, which is the smart contract that constitutes the ZK token on ZKsync Era, and is deployed as a transparent upgradeable proxy with role-based access control. The token admin role is held by the ProtocolUpgradeHandler; minting roles are held by the Token Governor timelock. Prior administrative roles were revoked following governance bootstrapping. Token distribution uses capped minters and a Merkle distributor. Each capped minter allows a designated role to mint ZK up to a specified maximum, enabling just-in-time minting rather than pre-minting the full 21,000,000,000 programmed supply cap at launch. The Merkle distributor controls airdrop claims through an immutable Merkle root representing eligible accounts and amounts. |
| H.3 | Technology used |
Architecture ZK uses a smart contract architecture on ZKsync Era comprising ZkTokenV1 as the core token contract, ZkCappedMinterV3 contracts for governed minting and a Merkle distributor for airdrop claims. The broader ZKsync Era system, sequencer, proving pipeline, Layer 1 verification contracts and data publication to Ethereum, provides ZK's execution environment, bridge context and finality model. Proof system and data availability ZKsync Era uses a SNARK-based proof system. After each batch is executed, a proof of the state transition is generated and submitted to Ethereum alongside compressed state diffs, Layer 2 to Layer 1 messages, logs and bytecodes. The Layer 1 verifier confirms proof validity and data availability before a batch is finalised. ZK state can therefore be reconstructed independently from Ethereum without relying on the sequencer Token deployment ZK is deployed at 0x5A7d6b2F92C77FAD6CCaBd7EE0624E64907Eaf3E on ZKsync Era. The ZkCappedMinterV3Factory is deployed at 0xABF70d9a1fe52ca5e9339A6Ef76759614C1b5eE9 on ZKsync Era. Active capped minters cover allocations for the airdrop (three successive distributor contracts), Matter Labs, the ZKsync Foundation, the Guardians, the Security Council and the ZKsync Association. New capped minters require at least one security review before deployment. The governance infrastructure comprises three governor and timelock pairs on ZKsync Era, the Protocol Governor, Token Governor and GovOps Governor, alongside a ProtocolUpgradeHandler and Emergency Upgrade Board on Ethereum. Governance contract addresses were updated following ZIP-5; current addresses are published in the ZK Nation documentation. Dependencies Token and governance contracts are written in Solidity using OpenZeppelin's upgradeable library for the proxy pattern, ERC-20 implementation, permit and access control. Governance contracts use Foundry for Layer 1 testing and Hardhat with ZKsync plugins for Layer 2 deployment. Both the standard Solidity compiler and the ZKsync-specific EraVM compiler are used. |
| H.4 | Consensus Mechanism |
ZK does not operate an independent consensus mechanism. It is a smart contract token on ZKsync Era and inherits the ordering, execution and finality characteristics of the ZKsync Era rollup and its Ethereum settlement layer. ZKsync Era sequences and executes transactions through the sequencer. Executed transactions are grouped into batches committed to Ethereum, proven by zero-knowledge proofs and then finalised by Ethereum Layer 1 verification. Preliminary confirmations from the sequencer are available ahead of on-chain finalisation, but economic finality is contingent on the relevant proof being accepted by Ethereum. The Layer 1 contracts verify proof validity, confirm data availability and process any Layer 2 to Layer 1 messages before a batch is considered final. Ethereum's proof-of-stake consensus secures the settlement layer on which ZKsync Era depends for finality. Validators stake ETH and are assigned responsibilities for block proposals and attestations. Ethereum time is divided into 12-second slots and 32-slot epochs. One validator is randomly selected as block proposer per slot; committees of validators attest to the proposed block. Finality is established when a supermajority link between two consecutive checkpoint epochs receives attestations representing at least two-thirds of total staked ETH. Reverting a finalised block requires the destruction of relevant validator stakes through slashing, making such reversion economically prohibitive. |
| H.5 | Incentive Mechanisms and Applicable Fees |
Network-level fees ZKsync Era fees reflect Layer 2 execution costs and Ethereum data publication costs. Layer 2 costs cover execution in EraVM and zero-knowledge proof generation for the batch. Since EIP-4844, ZKsync Era publishes data to Ethereum using blob-carrying transactions, reducing publication costs relative to calldata. The gas-per-pubdata-byte limit introduced in the ZKsync-specific transaction format (described in H.2) caps what any single transaction pays for that published data. A batch-level base fee is calculated from the prevailing Ethereum gas price, incorporating proof generation overhead and the cost of committing and verifying the batch on Ethereum. Protocol-level fees The ZK token contract imposes no transfer surcharge, burn fee or protocol fee. For ZK bridged to Ethereum, a deposit locks tokens in the Layer 1 shared bridge; a withdrawal returns the Layer 2 tokens and releases the locked balance. Validator incentives ZK is not an Ethereum validator reward asset. Ethereum validators receive ETH rewards for block proposals and attestations and are slashed for equivocation or other provably dishonest behaviour. These incentives secure the settlement layer described in H.4. Within the ZKsync Era, transaction fees are directed to a designated fee recipient; fee parameters and validator settings are governed by the ZKsync governance process. Governance of fee parameters ZK token voting power governs changes to protocol rules, token supply and operational parameters through the governance structure described in H.3. The Security Council and Guardians hold review, veto, freeze and emergency upgrade powers. Emergency procedures allow temporary freezes of Ethereum Layer 1 contracts. Protocol and token parameter changes require Token Assembly approval; the governance system is not controlled by any single entity. |

| I.1 | Offer-related risks |
Market volatility and liquidity The market value of ZK can fluctuate and execution quality may vary across trading venues and liquidity conditions. Large-holder and allocation concentration ZK allocations include approximately 33% for investors, advisers and team members, 19.9% for the ZKsync Foundation, 29.3% for ZKsync Governance and 17.5% for the airdrop. Large or closely sequenced disposals by significant holders may affect execution quality, liquidity and price formation. Access, eligibility and interface dependence Access to ZKsync-related services may depend on official interfaces, including bridge, portal, documentation, explorer and checkout sites. Eligibility restrictions, sanctions controls or interface unavailability may affect the ability to access, bridge or use ZK. Withdrawal delay and capital mobility Withdrawing ZK from ZKsync Era to Ethereum involves a minimum three-hour delay, with actual timing dependent on network activity and proof generation. This may constrain a holder's ability to move assets rapidly between layers during periods of market stress. Misleading asset and address-selection risk Third parties may create digital assets with misleading names or fake contract addresses. Bridged ZK token addresses on Layer 2 differ from Layer 1 addresses, so mistaken asset selection may affect users interacting with venues, wallets or bridges. Transaction finality and custody Once a transaction has reached the relevant finality point, recovery requires a further authorised transaction rather than protocol-level reversal. Loss or compromise of private keys can make on-chain recovery impracticable. Delisting Risks Bitstamp Europe S.A. might remove the token from trading in line with Bitstamp Markets Trading Rules. |
| I.2 | Issuer-related risks |
Governance and delegation concentration The Token Assembly is made up of ZK tokenholders who may delegate voting power. Concentrated delegation, low participation or co-ordinated voting may influence the Protocol Governor, Token Governor or GovOps Governor. The ZKsync Association does not control these governance bodies and cannot direct their outcomes. Once governance bootstrapping was completed, all three admin roles were transferred to on-chain governance contracts, and the Association's privileged roles were revoked. Admin-key and privileged-configuration risk In April 2025, an admin key administered by the ZKsync Association was compromised, enabling approximately 111,000,000 ZK tokens to be minted from three Merkle Distributor contracts via the sweepUnclaimed function. The key did not control the ZK token contract, governance contracts or any active capped minters, and user funds were not affected. The attacker returned approximately 90% of the stolen tokens under a safe harbour arrangement. Scoped admin permissions retained by the issuer entity can create token-specific operational risk even after broader governance decentralisation. |
| I.3 | Crypto-assets-related risks |
Supply mechanics ZK has a stated 21,000,000,000 total maximum supply with no inflation, and distribution uses capped minters rather than a pre-minted treasury. Errors, misconfiguration or governance decisions affecting minting, burning or allocation contracts may affect effective supply dynamics within the stated design. Governance utility and demand dependency ZK is used to vote on protocol upgrades and initiatives, and its economic function may be expanded through governance. Demand for ZK therefore depends on governance participation and adoption of ZKsync network functions. Token economics change risk Protocol fee structure, fee collection, allocation and token burns are subject to governance. Changes to economic parameters may affect perceived value, utility and holder expectations. Mint and burn authority risk The Token Governor can process proposals assigning minting and burning rights, and the November 2025 upgrade added permissionless burning and a BURNER_ROLE. Misuse or defective configuration of these powers may affect holder balances or circulating supply within the maximum-supply constraint. Address and bridged-token representation risk Tokens bridged between Layer 1 and Layer 2 have different addresses, and default bridge support is limited to standard ERC-20 functionality. Incorrect address selection or unsupported token behaviour can cause mistaken operations or failed integration assumptions. |
| I.4 | Project implementation-related risks |
Upgrade and migration execution risk ZKsync has an active upgrade and migration path covering governance contracts, bridge architecture, Gateway, interop messaging, ZKsync OS and token burn changes. Breaking changes or testing issues may affect implementation schedules and user operations. Governance execution dependency Protocol, token and governance operations proposals are handled through separate governors, timelocks and governance procedures. Proposal delay, rejection, veto or emergency procedure activation can alter delivery timelines and implementation outcomes. Emergency governance and freeze powers The Security Council can freeze the ZKsync protocol in emergencies, and emergency upgrades require approvals involving the Security Council, Guardians and the ZKsync Foundation. These powers support urgent response but create concentrated authority during emergency conditions. Guardian veto discretion Guardians have an independent power to veto proposals considered abusive, malicious or adverse. This discretion may prevent harmful proposals but can also delay or block changes that otherwise have tokenholder support. Supporting-entity dependence Matter Labs operates ZKsync sites and is one participant in the ZKsync ecosystem, while the ZKsync Foundation provides grants and enters into ecosystem agreements, and the ZKsync Association deployed the initial governance and token contracts. Disruption to these supporting roles may affect interfaces, governance operations or ecosystem support. Bridge implementation The ZKsync bridge operates through Ethereum Layer 1 smart contracts that process lock-and-mint deposits, burn-and-release withdrawals and cross-chain message finality. Defects in bridge contract logic, failed cross-chain messages or breaking changes introduced during bridge upgrades may cause misrouted assets, failed withdrawals or reconciliation failures between Layer 1 and Layer 2 balances. Third-party and interface dependency User operations may depend on the Portal, block explorer, APIs, wallets and service providers for bridging, transaction history, contract verification and visibility. Outages, inaccurate indexing, stale contract address data or interface restrictions can impair practical access even where protocol settlement remains available. Custom data availability and multi-chain configuration risk ZKsync supports custom data availability layers, and chains outside the official Chain Type Manager may carry different security guarantees. Incorrect configuration or weaker dependency assumptions may affect chain-specific risk profiles. Incident response coordination risk The April 2025 admin-key incident required coordination among Matter Labs, SEAL 911, the ZKsync Association, the ZKsync Foundation and the Token Assembly. Response quality and speed depend on clear authority, evidence gathering and governance follow-through. Regulatory and eligibility exposure Access to ZKsync-related interfaces and services is controlled by Matter Labs. Changes in the legal or regulatory framework, or in the implementation of compliance controls, may affect users’ ability to access such interfaces, participate in governance, or use related services. Data handling and privacy exposure Personal information may be processed for security, fraud prevention, legal compliance and service provision, and may be shared with service providers or transferred internationally. These practices create privacy, cross-border transfer and third-party processing risk for users interacting with official interfaces. |
| I.5 | Technology-related risks |
Smart-contract and protocol logic defects ZKsync relies on Layer 1 and Layer 2 contracts for bridging, governance, state-transition management and protocol operation. Defects in these contracts can affect deposits, withdrawals, upgrades, token mechanics or state verification. Upgradeable mechanisms and admin hooks ZKsync protocol contracts are upgradeable through an on-chain governance process administered by the Protocol Governor and timelock. Emergency situations may be handled through the Emergency Upgrade Board, which can bypass the standard proposal and delay the process to execute an upgrade immediately. Whilst this mechanism provides necessary response capability, emergency upgrades involve concentrated authority and accelerated execution, increasing the risk that an upgrade affecting protocol contracts or bridge operations is not fully reviewed before taking effect. Misconfiguration or a compromised governance participant during such a process could affect contract behaviour across the protocol. Sequencer ordering and censorship risk ZK rollups may rely on a sequencer or operator for batch production and transaction ordering, and centralised operators can influence ordering or exclude users. ZKsync's stack includes a sequencer component, creating an operational concentration point for transaction ordering and inclusion. Sequencer and prover operational dependency ZKsync OS Server is the sequencer and Airbender is the ZK proof generator. Availability or performance issues in sequencing or proving may delay transaction inclusion, proof production or settlement workflows. Prover and validity-proof risk ZKsync OS execution is decoupled from proving and Airbender generates validity proofs. Proof-generation resource constraints, prover defects or verification failures can delay settlement or weaken confidence in state-transition correctness. Bridge and interoperability risk Defects in bridge contract logic, token representation or cross-chain message handling can delay withdrawals, misroute assets or create reconciliation issues between Layer 1 and Layer 2 balances. Data availability and settlement dependency ZK rollups depend on published data and validity proofs so that state can be reconstructed and verified. Custom data availability support and settlement choices may change the security assumptions of particular ZKsync chains. Ethereum Layer 1 consensus and finality dependency ZKsync inherits Ethereum settlement-layer risks, including validator operation, execution and consensus client operation, and proof-of-stake finality assumptions. Severe Ethereum client, consensus, network or validator events may delay or impair final settlement and visibility for ZKsync operations. Resource accounting and execution constraint risk ZKsync OS tracks EVM-equivalent gas and native proving resources. Incorrect resource pricing, demand spikes or proving-resource bottlenecks can increase costs, delay transactions or cause execution failures. |
