Looking to trade on the Coinbase App or Coinbase Exchange? The Trade API is for onchain token swaps on Ethereum and Base networks. To trade on the Coinbase App, use the Coinbase App API (for individual traders) or check out our selection of Institutional APIs.

​
Overview

An onchain trade (otherwise known as a swap) is a transaction that exchanges one token for another, enabling automated trading, arbitrage opportunities, and sophisticated DeFi front-end applications.
The Beta launch of our Trade API supports Ethereum and Base mainnet networks only - stay tuned for additional network support!
The Trade API provides real-time price discovery and token swaps across multiple DEXes, enabling traders to access deep liquidity pools and execute at the best available prices. For the smoothest developer experience, use CDP Trade API with our Wallets - supporting both regular accounts (EOAs) and Smart Accounts with gas sponsorship. We also support the use of external wallet libraries like viem and web3.py for building with your own infrastructure.

​
