BridgeRadar

BridgeRadar is a cross-chain transaction risk simulator that shows what could go WRONG before you bridge—not just the best route.

Every bridge transaction is a leap of faith. Users have no visibility into security, liquidity depth, or failure modes before committing funds. BridgeRadar solves this by simulating your cross-chain transaction across all available routes before you execute.

Key features: • Multi-route risk scores (A–F grades) based on bridge security, liquidity, and execution time • Stress test simulation: "What if liquidity drops 30%? Gas 3x?" • Pre-flight checklist: security audits, upgradeability warnings, liquidity depth • ENS identity + wallet bridge history display • Shareable analysis URLs for judges and social proof

Others optimize for price. We optimize for NOT getting rekt.

BridgeRadar is built with Next.js 16, viem, wagmi, and Reown AppKit for wallet connection. The LI.FI SDK powers multi-route fetching across Arbitrum, Optimism, Polygon, Base, and Ethereum mainnet. We built a custom risk scoring engine using bridge security data (audits, exploits, TVL), liquidity depth, and execution time. ENS resolution via viem provides wallet identity and avatars. The stress test engine simulates disaster scenarios (liquidity -30%, gas 3x, price swings) client-side. We use Recharts for the radar visualization and Framer Motion for polish. All APIs are rate-limited; AI route explanation falls back to rule-based when OpenAI is unavailable. Deployed on Vercel.
