In a bold move to uphold international sanctions, ZK has announced the blocking of certain jurisdictions from participating in its highly anticipated airdrop. The restricted regions include Cuba, Iran, North Korea, Russia, Syria, and specific areas within Ukraine: Crimea, Donetsk, and Luhansk. These geographical limitations are necessary to comply with the sanctions regulations set forth by the U.S. Department of Treasury’s Office of Foreign Assets Control (OFAC), the United Nations Security Council (UNSC), the European External Action Service (EEAS), and His Majesty’s Treasury (HMT). Additionally, residents of the United States will also be prohibited from claiming the airdrop.
The second wave of ZK token claims is now live, and eligible participants can check their eligibility. This includes members of the Protocol Guild, contributors to external projects, and those nominated by ZKsync native ecosystem projects. This claim wave represents 1.91% of the total airdrop.
The snapshot for the ZK airdrop was taken on March 24, 2024, at 00:00:00 UTC, marked by Era Block Number 29710983 and Lite Block Number 187273. The airdrop claims for ZKsync users will commence the week of June 17th, 2024, and continue until January 3rd, 2025. A staggering 3,675,000,000 tokens will be distributed among 695,232 eligible wallets.
The airdrop is divided into two primary categories: Users and Contributors. Users, comprising 89% of the airdrop, have bridged funds onto ZKsync Era and met at least one of the seven eligibility criteria. Contributors, making up 11%, include individuals, developers, researchers, communities, and companies who have contributed to the ZKsync ecosystem through development, advocacy, education, or participation.
The usage-based airdrop process involves meticulously checking every address transacted on ZKsync Era and ZKsync Lite against the eligibility criteria. These criteria encompass interactions with smart contracts, paymaster activities, token trading, providing DeFi liquidity, holding Libertas Omnibus NFTs, ZKsync Lite activity, and donations to Gitcoin.
Allocations for eligible addresses are determined based on a value-scaling formula that adjusts an address’s allocation based on the amounts sent to ZKsync Era and the duration for which those crypto-assets remained in the wallet. Crypto assets in DeFi protocols are valued at twice their nominal value to emphasize their utility. The time-weighted average balance is calculated by summing the daily balances and dividing by the total number of days in the snapshot period, which lasted 366 days.
Addresses can receive additional multipliers based on certain activities that indicate a high likelihood of human behavior or contribution to ZKsync. These multipliers include holding specific ZKsync native NFTs or ERC-20 tokens, creating smart contract wallets via ZKsync Era native account abstraction, holding a percentage of the ARB/OP/ENS airdrop for more than 90 days, and early interactions with qualifying Ethereum smart contracts.
To ensure fairness and prevent bot swarms, a conservative sybil detection methodology is employed. This methodology groups externally owned accounts (EOAs) with common funding patterns or CEX deposit address reuse into clusters. Clusters with more than 20 EOAs are filtered out to eliminate potential bots.
