In the world of Web3, Sign (SIGN) is a specialized omni-chain attestation protocol. Its primary goal is to move beyond "don't trust, verify" by providing a universal infrastructure where any claim—be it a legal contract, a university degree, or a social media identity—can be cryptographically verified on-chain.

Core Components of the SIGN Ecosystem

Sign Protocol: Acts as a digital notary. It allows users to issue "attestations" (signed statements) that are tamper-proof and accessible across different blockchains like Ethereum, Solana, and TON.

TokenTable: A distribution engine that uses these attestations to manage token airdrops and vesting schedules. For instance, a project might only distribute tokens to users who have a "signed" attestation proving they participated in a specific testnet.

EthSign: The flagship decentralized application (dApp) for signing digital agreements. It replaces traditional services like DocuSign with blockchain-backed security, ensuring that once a document is signed, its history is immutable.
