Dual-layer on-chain liquidity protocol

A dual-layer architecture for pricing event-triggered real-world assets — specifically preclinical biotech milestone rights, where no liquid market exists to price binary R&D outcomes.

Permissioned ERC-3643 SPV token on Ethereum Sepolia for the asset itself; LS-LMSR automated market maker on Base Sepolia for price discovery; bridged via Circle CCTP for USDC settlement. Scoring-rule pricing implemented in Solidity using PRBMath UD60x18. Includes a "seed-and-retreat" cold-start mechanism.

Validated via a 4-class multi-agent trading simulation (credentialed, noise, momentum, adversarial) across a ~3,900-cell parameter sweep — showing ≥97% convergence to true probability under credentialed-dominant agent mixes (median 312 ticks), robust to adversarial attacks ≤25% of seeded liquidity. Solidity–Python parity verified.
