According to X user @lingland09, an individual within the zkSync ecosystem appears to be operating as an airdrop hunter, possessing 21,877 interacting addresses. His strategy involves providing a minimal amount of ETH to fund all of their wallets, followed by deploying a non-open-source token called “Gemstone.” Subsequently, they list all 21,877 of their witch addresses on the token's whitelist, allowing them to claim all tokens self-deployed.
The airdrop hunter has also created a non-open-source DEX, indirectly establishing an index for application trading between their witch addresses. He then added over 80 ETH in liquidity to the Gemstone token on his self-made DEX, imparting value to Gemstone. He further achieved interactions by exchanging previously claimed Gemstone tokens from the 21,877 wallets in the Gemstone/ETH trading pair, continuously repeating this process. All transactions are executed automatically by their self-authored bots, rather than manually.
Since all liquidity is personally added, it remains unaffected by slippage and accumulates ten transactions in the cheapest manner possible on the zkSync Era network. They extended this pattern algorithm to over 21,000 wallets without being affected by slippage.
This address conducts transactions on a monthly, weekly, and daily basis, with transaction fees ranging from $1.5 to $2 per witch address. They completed a total trading volume of $10,000 and ten transaction counts, aligning their on-chain behavior with eligibility for airdrop issuance similar to other Layer 2 projects.
