Whenever you need to prove something onchain — identity, action, ownership, or permission — you don’t need to write a new smart contract or spin up a ZK system.
Attest provides a proof infrastructure to build anything from network states, DAOs, DePIN, and RWA. With our Unified Trust Framework, developers on Stellar can integrate reputation and trust mechanisms in their dApps.Add proof to anything, on-chain without writing a line of code.
AttestProtocol is a Soroban-based framework that lets you attach attestations to any wallet, asset, or event. Whether that’s proof of identity, contribution, credential, or ownership. No contracts, no infrastructure, no ZK black magic required.An Open Standard for Trust
Using our Attestation Service you get an open standard for verifying statements, transactions, and authorities — identity proofs on the blockchain. Our Soroban framework enhances the reliability of digital interactions on the Stellar Network with a composable blockchain-based Attestation Service.Use Cases
