CredLink: On-Chain Credit Bureau

CredLink is an on-chain credit bureau that stores a canonical score per wallet. A Chainlink CRE workflow computes a score off-chain, reaches consensus, and writes the score on-chain for DeFi consumers.

Architecture

HTTP Trigger -> Fetch Scoring API -> Compute Hashes -> Consensus -> Chainwrite setScore()

Components

  • contracts/: CreditBureau registry + LoanManager consumer policy
  • scoring-api/: deterministic scoring API (mockable)
  • workflow/: CRE workflow that hashes signals and writes to Sepolia

Where Chainlink/CRE is used

  • The CRE workflow fetches the scoring API, performs hash computation, reaches consensus, and performs the chainwrite to CreditBureau.setScore(...).
