0x

0x is a trading infrastructure platform for developers that want to add token swaps, routing, and onchain execution to their apps.

Its APIs aggregate liquidity from a large set of sources across many supported networks, returning quotes and transaction data without requiring teams to integrate every venue separately.

Builders use 0x for embedded swaps, gasless flows, trade analytics, and cross chain routing, while users keep control of their wallets and sign transactions directly onchain through the apps that integrate it.
