Problem Statement
AI agents operating on-chain have no way to verify whether another agent or contract is trustworthy. Reputation today is unfalsifiable — any agent can claim 99% accuracy with zero proof. When agents delegate funds to or trade with unverified counterparties, they risk real money on unverifiable claims. ERC-8004 gives agents identity but not trust verification. There is no on-chain mechanism to economically test and price an agents reliability before transacting with it.
On-chain trust scoring and prediction insurance for AI agents on Base. Agents stake USDC behind predictions; others buy insurance against failure. The insurance price becomes a real-time, Sybil-resistant trust signal. Key innovation: economically falsifiable reputation. Insurance pricing creates a continuous, market-driven trust score. Bad agents get expensive insurance. Good agents get cheap insurance. The price IS the trust metric. Proven multi-agent on-chain: - 3 separate wallets (Predictor, Insurer, Validator) with distinct on-chain identities - 28+ cross-wallet transactions across 5 full prediction lifecycle rounds - Insurance purchases provably from different addresses (CannotInsureOwnPrediction enforced) - Alternating resolution outcomes demonstrating trust score dynamics On-chain artifacts: - 3 agents registered on ERC-8004 IdentityRegistry (Base mainnet) - 4 hardened Solidity contracts redeployed on Base Sepolia (20/20 tests) - All contracts verified on Blockscout with source code - 28+ on-chain lifecycle transactions Powered by: - Pyth Network oracle for verifiable price resolution - CoinGecko real-time market data (3-tier fallback) - x402 payment-required API endpoints - ERC-8004 agent cards with resolvable metadata Stack: Foundry, ethers.js v6, TypeScript, Next.js, Express, OpenZeppelin, Pyth, CoinGecko

Planning to integrate with real ERC-8004 IdentityRegistry on Base mainnet, add Chainlink oracle for price resolution, and deploy as production infrastructure for the Solder ecosystem.
