TrustLayer
For Developers

On-Chain Proofs Reference

Every off-chain proof has an on-chain commitment. Contracts can trust TrustLayer without calling any centralised service.

Core view functions

  • trustScoreOf(address wallet) → uint256
  • hasBadge(address wallet, bytes32 badgeId) → bool
  • vouchedBy(address vouchee, address voucher) → bool
  • merkleRoot(uint256 epoch) → bytes32

Merkle proof verification

For gas-sensitive integrations, use the epoch Merkle root plus an off-chain proof. TrustProofVerifier.verify(proof, leaf, root) returns true if the wallet was included in that epoch snapshot.
