What blockchains does 0x support?

0x supports a wide range of chains across its products. This article gives the current high-level picture. Because 0x adds chains regularly, the Supported Chains and Providers page in the docs is always the canonical, up-to-date source.

Swap API and Gasless API (EVM chains)

The Swap API supports the following EVM chains: Ethereum (Mainnet), Abstract, Arbitrum One, Avalanche C-Chain, Base, Berachain, BNB Smart Chain, HyperEVM, Ink, Linea, Mantle, Monad, OP Mainnet, Plasma, Polygon, Scroll, Sonic, Tempo, Unichain, and World Chain.

The Gasless API supports the same chains, with one exception worth noting: Linea is supported on Swap API but not on Gasless API. Every other chain in the list above supports both.

Solana Swap API

Beyond EVM, 0x offers a dedicated Swap API for Solana (the SVM ecosystem), provided as a separate product from the EVM Swap API.

Cross-Chain API

The Cross-Chain API spans a broad set of networks — including the EVM chains above plus Solana, HyperCore, and Tron — and routes across many bridge providers to move tokens between them. Coverage varies by chain (some networks are supported only as an origin or only as a destination), so check the docs for the specifics of any given route.

For the full, current list

Chain availability changes often, and exact details — including chain IDs, per-chain Gasless support, and Cross-Chain bridge-provider coverage — live in the Supported Chains and Providers documentation. Always treat the docs as the source of truth.
