Tools (10)

bind_identityBind a fleet DID to an ERC-8004 identity. Produces an order-independent, content-addressed (unsigned) binding attestation.
describe_agentReturn the bridge's capabilities and input contract.
export_attestationExport 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_responseBuild 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 bridge holds no keys and writes to no chain.
import_feedbackImport 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_registrationImport 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_registrationsList all imported ERC-8004 registrations.
resolve_agentResolve an imported ERC-8004 registration by bridge DID or by (chain_id, token_id).
score_agentDecay-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_attestationRecompute a payload's content hash and report whether it is intact.
