Sign Protocol is a suite of solutions that enable users and enterprises to create secure and verifiable attestations of claims or assertions, in the real world and on the web.
Sign focuses on your everyday use cases: contract signing, airdrop reward claiming, and more.
Sign Protocol is an omni-chain attestation protocol, enabling users to freely attest and retrieve structured and verifiable data on-chain. It also accommodates large size data by offloading storage to IPFS* and Arweave.
