BLOCKCHAIN FUZZING

Cross-Chain Solver Validation

Problem

DeFi solver aggregating routes across 5+ chains with complex liquidity calculations. Traditional testing missed edge cases in cross-chain state synchronization.

Architecture

Built Foundry fuzz test suite with Anvil fork orchestration. Simulated 10,000+ route permutations with randomized slippage, gas prices, and liquidity depths.

Impact

Caught 3 critical pricing bugs before mainnet. Reduced regression time from 4 hours to 15 minutes via parallel fork execution.

AI-AUGMENTED AUTOMATION

AI-First QA Pipeline

Problem

E2E test suite for DeFi card infrastructure required constant maintenance. UI changes broke selectors weekly, consuming 30% of QA capacity.

Architecture

Integrated Claude MCP for test generation and self-healing selectors. Built validation pipeline using Cursor + LLM for logic verification and debugging.

Impact

80% of test generation now automated. Selector maintenance reduced to near-zero. QA velocity increased 3x without additional headcount.
