Aegis Protocol

On-chain binary prediction markets on Solana — LMSR pricing, batch-settled orders and a decentralised oracle network.

Dynamic b scaling gives 300,000× the manipulation resistance of a static b. The fixed-point LMSR with Taylor-series softmax cleared 158 million libFuzzer executions with zero failures.

Next.js and wagmi dApp, deployed on Sepolia.

Sentinel Mind

Five AI agents, one contract. Each owns a different attack surface — vulnerabilities, economics, access control, documentation.

They debate, conflict, and converge into a single battle-tested audit report.
