Eligibility Criteria

Eligibility for the zkSync airdrop was based on the following requirements:

Usage-Based Airdrop

Every address that transacted on ZKsync Era or ZKsync Lite was checked against the eligibility criteria. Each address needed at least one point from the following activities:

  • Interacting with at least 10 non-token smart contracts.
  • Using paymasters for at least 5 transactions.
  • Trading at least 10 distinct ERC-20 tokens on ZKsync DEXs.
  • Providing any liquidity to tracked DeFi protocols.
  • Holding at least 1 Libertas Omnibus NFT.
  • Being active for 3+ months on ZKsync Lite.
  • Donating to Gitcoin rounds on ZKsync Lite.

Allocation

Allocation was determined by a value-scaling formula, which accounted for:

  • The amount of crypto-assets bridged to ZKsync Era.
  • How long assets remained in the wallet.
  • Crypto-assets held in DeFi protocols were valued at 2x their nominal value.

Multipliers

Certain activities increased token allocations:

  • Holding specific ZKsync NFT collections.
  • Holding $50+ of certain ZKsync native ERC-20 tokens.
  • Using smart contract wallets created via ZKsync native account abstraction.
  • Holding 50%+ of ARB/OP/ENS airdrops for 90+ days.
  • Being among the first 1,000 addresses to interact with high-value Ethereum smart contracts.

Sybil Detection

To prevent bot activity, a conservative heuristic framework was applied:

  • CEX Deposit Address Reuse: EOAs sending funds to the same CEX deposit address were grouped.
  • Common Funding Patterns: Addresses funded from the same sources in similar time frames were grouped.
  • Filtering Large Clusters: Clusters of 20+ linked EOAs were removed from the airdrop.

Contribution-Based Airdrop

The following groups received additional allocations:

  • ZKsync Native Projects: 215,250,000 ZK allocated to projects building on ZKsync Era (DeFi, gaming, infrastructure, etc.).
  • Builders: 86,895,375 ZK allocated to individual contributors, including GitHub Developers (25+ commits), Ethereum researchers (Protocol Guild), and GitHub discussion participants.
  • Security Researchers: Participants in security audits via Code4rena, Cantina, or Codehawks.
  • Community Moderators: Moderators and zkStars program members.
  • Event POAP Holders: Individuals who attended ZKsync in-person events and collected specific POAPs.

Onchain Communities Airdrop

A portion of the airdrop was allocated to experimental onchain communities:

  • $DEGEN Airdrop Recipients: Season 1 $DEGEN airdrop recipients on Farcaster.
  • $BONSAI Airdrop Recipients: Season 1 $BONSAI airdrop recipients on Lens.
  • Crypto The Game: Participants in Season 1, Season 2, and the CTG team.
  • Pudgy Penguin & Milady Maker Holders: Holders of these NFTs (allocated per address, not per NFT).
