MolTrust Trust Registry

Production trust infrastructure for autonomous AI agents. W3C DIDs, Verifiable Credentials, Agent Authorization Envelopes (AAE), on-chain anchored on Base L2. Reference implementation of the Trust Registry Binding for A2A v1.0.

Skills

• Agent Trust Score
  Returns W3C DID-based trust score (0-100) with behavioral history breakdown, sybil penalty, anomaly flags, on-chain proof. Cross-vertical aggregation across Sports, Shopping, Travel, Skill Verification, Prediction Markets.

• DID Resolution
  Resolves W3C Decentralized Identifiers (did:moltrust) to DID Documents with verification methods and service endpoints. DIF Universal Resolver compatible (driver published at uresolver.moltrust.ch).

• Verifiable Credential Verification
  Verifies W3C Verifiable Credentials including Agent Authorization Envelopes (AAE) with delegation chain validation. Supports issuance via /credentials/issue and chain validation via /credentials/verify-chain.

• Wallet Binding Verification
  Verifies cryptographic binding between agent DID and blockchain wallet address (EVM Base + Solana). Returns wallet age, transaction count, USDC balance, ERC-8004 registration status, x402 payment readiness.

• Wallet Track Record Credential
  Issues a TrackRecordCredential over a wallet bound to the DID, stating what that wallet has done on Base: transactions sent, age in days, transfer count, USDC volume, next to the thresholds the issuance was judged against. Issued via /credentials/track-record; the first one per DID is free. A gate configured for it reads the anchored credential in place of a trust score that has not been computed, which is the route open to an agent with no endorsers yet.

• Sybil & Anomaly Detection
  Two-layer sybil detection: (1) embedded in trust-score response (flags array + sybil_penalty in breakdown), (2) dedicated paid endpoint via MoltGuard with on-chain wallet age, counterparty graph, funding-source clustering. Paid via x402 ($0.10 USDC).

• EU AI Act risk classification
  Classify an AI system under Regulation (EU) 2024/1689: risk tier (prohibited/high/limited/minimal), obligations checklist, gap analysis, with EUR-Lex article pins.

• EU declaration of conformity (Annex V)
  Issue an Annex V EU declaration of conformity as a signed W3C Verifiable Credential (MolTrustConformityDeclaration).

• Batch reputation
  Reputation scores and ratings for up to 500 agent DIDs in a single call.

• Merkle batch anchoring
  Merkle-batch a set of evidence hashes into a single root with per-leaf proof paths.

• Amazon Ads Verdict Gate
  Allow, hold or forbid for an intended Amazon Ads MCP Server tool call (budgets, bids, campaigns), checked against the agency's mandate for that ad account before the call runs. Deny-by-default; user-access tools are never grantable; every verdict carries a recomputable record. MolTrust holds no Amazon credentials and never calls Amazon. MCP tools ads_onboard, ads_mandate_template, ads_check at https://api.moltrust.ch/mcp; REST POST /enforce/check (X-API-Key), POST /ads/demo. Free: 1 ad account, 1,000 checks/month; Pro USD 49 per ad account/month.
