ProtocolX

ProtocolX is an autonomous multi-agent DeFi system that monitors on-chain markets, detects arbitrage, risk, and yield opportunities, and executes cross-chain strategies automatically. Agents interact programmatically with Uniswap v4 for trade execution, use LI.FI for cross-chain routing, and settle capital through Arc as a unified USDC liquidity hub, ensuring a single-balance experience across chains. The system uses simulation-first execution, deterministic decision logic, and transparent transaction logging to provide reliable, auditable autonomous financial operations.

ProtocolX is built as a modular agent engine using TypeScript and Node.js, with on-chain execution powered by Wagmi/Viem and protocol SDKs. The arbitrage, risk, and yield agents continuously monitor the on-chain state, compute deterministic strategy decisions, simulate transactions using Uniswap v4 Universal Router calls, and execute only after profitability and safety checks pass. Cross-chain asset movement is handled through the LI.FI SDK, enabling automated routing and bridging across chains, while Arc is used as the USDC liquidity and settlement hub so all strategies operate from a unified capital base. ENS integration provides agent identity and delegation. A notable implementation detail is the simulation-first execution pipeline: every strategy constructs the exact calldata, runs a local transaction simulation to estimate slippage, gas, and outcomes, and commits the transaction only then, ensuring reliability and preventing failed or unprofitable executions.
