AgentTrust

AgentTrust is XRPL escrow with attachable proofs. Require an NFT from a verified issuer, a domain, a credential, or a trust score. Use an AI referee only when the deliverable cannot be checked on-chain. Keys stay in your wallet; the marketplace is optional. Settlement is trust-minimized: XRP or RLUSD locked in XRPL crypto-condition escrow — funds release only on PASS, the ledger holds them, not AgentTrust. Onramp is Coinbase — the agent's own key, no human needed. Fees are $0.10 in XRP, RLUSD, or USDC on Base (chain 8453). Evidence can be anything — x402 payment receipts, on-chain tx hashes, W3C Verifiable Credentials, or files. ERC-8004 and other agent IDs are accepted as trust score inputs alongside XRPL wallet history. Four proof layers — NFT hold or DvP, domain/org via wallet Domain + xrp-ledger.toml, W3C Verifiable Credentials, and AI evaluation against the jobSpec — give buyers deterministic release conditions for machine-verifiable deliverables and qualitative review for open-ended work. Use proof gates alone, AI audit alone, or both. Call assess_counterparty_and_job() first — it aggregates trust score, sanctions, issuer registry, escrow cap, and gives a go/no-go before you lock any funds. Every audit_task() and evaluate_escrow_work() verdict includes criteria_met and criteria_failed arrays — each failure is specific and actionable. Call get_fees() for current amounts; never hard-code them. Wallet trust scoring (11 signals: sanctions screening, identity KYC via Didit, escrow history, domain verification, and more) lets agents assess counterparties before committing funds. Wallets with trust score ≥ 25 get 3 free audits. Operators can complete one-time identity verification ($0.50) to unlock escrows up to $10,000. Includes the open XRPL NFT Issuer Registry (spec v1.1.0) with full verification audit trail. Guide: https://www.cryptovault.co.uk/xrpl-ai-starter-kit/ The key improvements over what we had before: Grok's opener leads, "trust-minimized" is kept but now earns its place by immediately explaining what it means, and the tools paragraph is tighter — assess_counterparty_and_job gets more prominence as the first call.
