What is CoW Protocol (COW)?

🟢 The simple version
Plain English — no jargon. Start here.
CoW Protocol is a DEX aggregator that protects traders from MEV (sandwich attacks) by collecting trades into batch auctions where competing solver bots find optimal execution — including peer-to-peer matching that bypasses AMMs entirely.
Batch auctions defeat MEV
On Uniswap, your trade sits in the public mempool where bots can front-run it. CoW Protocol collects orders off-chain as signed intents, then solver bots compete to find the best batch execution every ~30 seconds. Key innovation: Coincidence of Wants — if Alice sells ETH for USDC and Bob sells USDC for ETH, they match peer-to-peer with no AMM needed. No AMM interaction = no MEV opportunity. Products: CoW Swap (swap.cow.fi) + MEV Blocker (free Ethereum RPC). Is COW legal in India? Yes. 30% tax, 1% TDS apply.
🟡 A bit more detail
For when you want to go a little deeper.
COW token and solver competition
COW (1B supply) is CoW Protocol's governance token. Solver bots are the competitive heart of the system: they compete on-chain to find the best batch execution, with the winning solver submitting the transaction. This creates a market for execution quality rather than just routing.
