#signdigitalsovereigninfra $SIGN Multi-chain compliant airdrop: Trustless solution from Sign Protocol
In Web3, airdrops are an important tool to attract users, but they always come with issues such as Sybil, unfair distribution, and KYC/AML risks. Relying on centralized KYC parties increases costs and reduces transparency.
@SignOfficial addresses this by using multi-chain verification, allowing KYC data to be verified and utilized across multiple blockchains like Ethereum, Solana, TON, and Base.
How it works
Create schema for KYC data
Issue attestation (electronic signature) linking wallet with KYC status
Cross-chain attestation through SignScan
TokenTable automatically verifies and distributes airdrop through smart contract
Only eligible wallets receive tokens, according to mechanisms like cliff and linear unlock — all transparent, on-chain, and no intermediaries required.
Real case: ZetaChain 2024 airdrop distributed 17.79M ZETA (~29.7M USD) to 14,700 KYC wallets, via Sign + TokenTable + SumSub.
In total, TokenTable has processed over 4 billion USD, reaching more than 40 million users.
