SimpleSwap is a self-custodial, multi-source crypto swap aggregator that lets users exchange cryptocurrency directly wallet-to-wallet, rather than depositing funds into an exchange-held account. The SimpleSwap exchange has operated since 2018 and today is integrated into 6,000+ partner products and crypto services — meaning many users encounter its swap functionality embedded inside another wallet, app, or platform rather than on simpleswap.io directly.
As an aggregator, SimpleSwap doesn't run its own single order book. Instead it routes each order across 20+ centralized exchange (CEX) and decentralized exchange (DEX) liquidity providers, aiming to fill the trade using the combined liquidity of that network. This is what allows it to list 2,800+ cryptocurrencies and 3.2M+ trading pairs.
