Sign Protocol

Sign is building a global distribution platform for good services and assets. Signatures, Sign's first product, allows users to sign legally binding agreements using their public key, creating an on-chain record of agreement to the terms of the contract. Sign's second product is TokenTable, which helps the Web3 project execute, track and enforce the project's use in distributing its tokens.
What is Sign Protocol?
Sign Protocol is an omni-chain attestation protocol that enables users to verify and attest information on the blockchain. It focuses on creating a transparent, secure, and efficient token distribution infrastructure for both humans and AI agents. By leveraging decentralized technologies like blockchains and zero-knowledge cryptography, Sign aims to improve verification processes across various applications, such as contract signing, token management, and credential validation.
How Does Sign Protocol Work?
Sign Protocol offers a scalable solution for verifying claims and assertions on the blockchain. It supports multiple blockchains, providing a chain-agnostic platform for issuing attestations. Users can verify claims or credentials across different blockchain networks, including EVM-based chains, Starknet, Solana, and TON. The protocol provides two modes for storing attestations: on-chain mode for decentralized data storage and off-chain mode utilizing platforms like Arweave for cost-effective storage. It also supports zero-knowledge proofs, digital signatures, and other cryptographic proofs to verify consent, ensuring broad interoperability.
What Makes Sign Protocol Unique?
Sign Protocol's key features include omni-chain attestation, supporting multiple blockchains for cross-platform compatibility; flexible storage options with both on-chain and off-chain modes; verifiable consent through zero-knowledge proofs and digital signatures; and privacy features allowing passwordless private attestations, making it ideal for sensitive applications like contract signing and credential verification.
Who Are the Founders of Sign Protocol?
Sign Protocol traces its roots back to the EthSign project, which debuted as a blockchain-based document signing tool in Q3 2021. In early 2024, the team rebranded and officially launched the omni-chain attestation service as Sign Protocol. The project is led by co-founders Xin Yan (CEO), who sets the strategic vision, and Jack X (CTO), a blockchain veteran and former USC lecturer.
