Tools

• bind_identity ~146 tokens
  Bind a fleet DID to an ERC-8004 identity. Produces an order-independent, content-addressed (unsigned) binding attestation.
• describe_agent ~51 tokens
  Return the bridge's capabilities and input contract.
• export_attestation ~126 tokens
  Export the agent's current trust score as an UNSIGNED ERC-8004 Validation Registry-shaped payload, content-addressed and ready for YOUR OWN signer to anchor on-chain.
• export_validation_response ~228 tokens
  Build UNSIGNED ERC-8004 Validation Registry validationResponse args from an Outcome Receipt (ORC v0.1): responseHash = receipt commitment, tag "orc/0.1", response 100 only if the bridge re-verifies the receipt AND your replay succeeded. Sign and submit with your own signer; this brid
• import_feedback ~158 tokens
  Import ERC-8004 Reputation Registry feedback records for an agent. Each item: {value: bool|0..1, at: ISO-8601, source?, weight?, feedback_id?}. Idempotent per feedback_id.
• import_registration ~214 tokens
  Import an ERC-8004 Identity Registry record (chain_id + ERC-721 token_id + agentURI + owner). Idempotent: re-import updates in place. Returns the canonical record with its deterministic bridge DID (did:viridis:erc8004:<chain>:<token>).
• list_registrations ~50 tokens
  List all imported ERC-8004 registrations.
• resolve_agent ~132 tokens
  Resolve an imported ERC-8004 registration by bridge DID or by (chain_id, token_id).
• score_agent ~163 tokens
  Decay-weighted trust score in [0,1] + tier over the agent's imported ERC-8004 feedback — recent behavior outweighs old; no feedback scores a neutral 0.5 prior (no blind trust, no unfair zero).
• verify_attestation ~85 tokens
  Recompute a payload's content hash and report whether it is intact.
