Providus
Providus is an institutional-grade risk engine that runs directly on-chain using Arbitrum Stylus. It computes Value at Risk (VaR) and Expected Shortfall (ES) — the same metrics banks use to evaluate portfolio risk without relying on a centralized server or a trusted oracle. The core breakthrough is a Log-Space Optimization that removes computationally expensive exponential functions from the Monte Carlo simulation loop. This makes 10,000-path simulations viable on-chain for the first time — something impossible on standard EVM due to gas constraints. Arbitrum Stylus (Rust → WASM) is the only execution environment where this works. The full product ships with: a live Protocol Stress Test Simulator (Aave V3, Maker, Compound presets), cryptographic on-chain proof generation, PDF report export, a developer API with tiered billing, API key management, webhooks, and a TypeScript SDK.

DeFi protocols today over-collateralize to compensate for having no real-time risk math — you deposit $150 to borrow $100. Providus gives them a verifiable, on-chain risk number they can use to dynamically manage collateral instead. Even a 5% reduction in idle over-collateralization across DeFi's ~$100B TVL frees $5B in capital.
