CoW Protocol Services Overview
CoW Protocol Services is the backend infrastructure powering CoW Protocol, a decentralized trading system using batch auctions. The services handle order validation, auction management, solution computation, and settlement across multiple EVM networks.
Key Capabilities
The system offers several important features:
- MEV Protection: Batch auctions protect traders from frontrunning and sandwich attacks by executing all orders at uniform clearing prices
- Best Execution: Competition between solvers sources liquidity from multiple venues
- Gasless Trading: Solvers cover gas costs upfront, enabling efficient batching
- CoW Matches: Direct peer-to-peer settlement when buy and sell orders overlap
Multi-Chain Operations
The services operate on Ethereum Mainnet, Gnosis Chain, Arbitrum One, Base, Polygon, BNB Chain, and additional networks including testnets. Each deployment operates independently with its own orderbook and settlement infrastructure.
Core Components
Four main service modules coordinate the system:
- Orderbook - HTTP API for order submission and status queries
- Autopilot - Manages auction lifecycle and solution ranking
- Driver - Handles liquidity collection and on-chain submission
- Solver - Computes optimal routing and order matching
Technical Foundation
The services use Rust with Tokio for asynchronous operations, PostgreSQL for storage, and Alloy for blockchain interactions. The system is licensed under GPL-3.0-or-later.
