Problem Statement

Sybil self-reporting inspired by LayerZero https://medium.com/layerzero-official/addressing-sybil-activity-a2f92218ddd3.Using EthSign it allows to store self-reports data onchain and reuse in every possible future airdrop. Users can report themselves and revoke their reports. To clarify - the attesters are the one who report themselves.

Solution

EthSign schema was created https://scan.sign.global/schema/onchain_evm_8453_0x31 on Base. Example attestation transaction is https://basescan.org/tx/0xb37324a178b829e85cc857fe291a3f13078f03ca2947fe5661939eb0634a794a.Then I created a frontend to interact with using rainbowkit+wagmi+ethsign sdk. EthSign indexing service is used to identify the status of the user.
