QuickSwap is a decentralized exchange (DEX) where you swap tokens and provide liquidity straight from your own wallet. Trades run against smart-contract liquidity pools, not an order book or a company's balance sheet. It began on Polygon PoS and, as of October 2026, its docs list nine supported networks, including Base and Ethereum 12. QuickSwap runs three pool designs (V2, V3 and V4) and also offers limit orders, farms and a perpetuals venue. Holders of its QUICK token vote on protocol changes 567.
