YieldProof
Human-verified RWA yield claims with on-chain attestation and reputation
Demo
About
YieldProof is an on-chain verification protocol for real-world asset (RWA) yield claims. Issuers submit yield claims with supporting evidence, while independent attestors stake funds and verify the claims. World ID helps establish unique-human attestors and reduce Sybil risk, while ENSv2 gives verified attestors a portable on-chain identity and reputation. Multiple attestations are combined through protocol-defined consensus to produce a transparent, verifiable result on-chain.
How it's made
YieldProof is built with Solidity smart contracts and a web frontend, with RWA evidence committed through IPFS. The protocol manages claim creation, attestor registration, staking, attestations, consensus, rewards, slashing, and reputation on-chain. We integrated World ID/IDKit into the attestor onboarding flow so unique-human verification is an actual eligibility requirement rather than just authentication. ENSv2 is used to create portable attestor identities and expose reputation such as verification status, trust score, and verified claims. The frontend connects users to the deployed contracts through their wallets and provides the complete claim-to-verification workflow.
