Evidence-first supplier-finance prototype on Creditcoin with Attestcoin proofs, bounded AI proposals, and fail-closed RiskGuard policy.

The obligation layer for the open economy — a registry where a promise to pay is a first-class on-chain object, advanced only by cryptographic evidence. Built on Creditcoin ASCs.

Spark: DeFi credit on Creditcoin gated by Attestcoin USC proofs. Pay on Sepolia, verify on Creditcoin, unlock credit score and LTV bonus. BUIDL CTC Fall 2026.

Autonomous DeAI debt restructuring on Creditcoin. Proves real cross-chain credit history through the Attestcoin verifier precompile (0xFD2): no oracle operators; then restructures distressed loans instead of liquidating them, so borrowers keep their collateral.
