MolTrust

• Name: MolTrust
• URL: https://moltrust.ch/
• Category: agent trust gate / credential-and-screening middleware / x402 sidecar
• Tags: ethereum-ecosystem
• Summary: MolTrust is a trust gate for agent payments, not a payment rail. Scores, credentials, and threshold policy are the product; x402 is just where the gate bites. Useful because it makes the gate explicit instead of hiding it inside seller policy.
• What it does:
  • Provides wallet-level trust scoring for Base addresses using onchain activity, counterparties, balances, ERC-8004 registration, reputation cross-references, and Sybil penalties
  • Runs the MoltGuard API for agent scoring, Sybil detection, Polymarket anomaly monitoring, and verifiable-credential issuance and verification
  • Issues W3C Verifiable Credentials signed with Ed25519 and anchored to MolTrust’s DID and identity infrastructure
  • Supports agent discovery and trust exchange through DID:web, ERC-8004 references, A2A-compatible agent cards, and MCP tools
  • Accepts agent-native payment patterns via x402 on Base and Lightning payments, while also offering public free-tier endpoints during early access
  • Ships developer integration surfaces including an MCP endpoint and the @moltrust/x402 middleware that checks paying-wallet trust scores before allowing x402 payment flows to continue
• Key claims:
  • The live product is the trust gate: scoring, credential issuance, and screening before payment proceeds.
  • MoltGuard is the useful surface because it exposes actual score inputs, Sybil checks, anomaly monitoring, and credential tooling instead of vague trust-language marketing.
  • The @moltrust/x402 middleware is the real control point: inspect the payment header, query MolTrust, enforce a threshold, and decide whether the sidecar fails open or fails closed.
  • Treat MolTrust as Base-heavy trust middleware riding above stronger payment and authorization rails, not as a settlement or protocol center.
• Whitepaper: No canonical standalone MolTrust or MoltGuard whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, MoltGuard product page, API docs entrypoint, and public middleware repository; see ../whitepapers/moltrust-primary-sources-2026-05-03.md.

Internal linkages

• Strongest adjacent reads: x402 and agent-passport-system.

Control surface

• The leverage sits in score inputs, credential issuance, fail-open versus fail-closed policy, threshold setting, and which wallets or agents the middleware lets transact.

• That matters, but it is still a trust gate riding above stronger payment and authorization rails rather than the rail itself.
