For the avoidance of any doubt, the most up to date list of routers is available in GitHub here. Note that UniswapX is subject to certain chain restrictions: UniswapX V2 only supports swapping on Mainnet (1), Arbitrum (42161), Base (8453), and Unichain (130). UniswapX V3 only supports swapping on Arbitrum (42161). If you submit a quote request in which the protocols are limited to just UNISWAPX_V2 or UNISWAPX_V3 and you specify an unsupported chain, the request will fail. Further note that all UniswapX protocol quote requests on an L2 network require a minimum 300 USDC-equivalent value. For most integrators we recommend only utilizing UNISWAPX_V2.

How Do I Swap Native Tokens?

To swap native tokens, use the address 0x0000000000000000000000000000000000000000. Please note that token trading for native input is not currently available for UniswapX.

​
Supported Tokens for Swapping

Generally any two tokens on any supported chain can be swapped. However, Uniswap Labs maintains a list of “unsupported” tokens, for which we do not permit swapping through any method due to legal or regulatory restrictions. Those tokens and their chains are available here: https://unsupportedtokens.uniswap.org/. If one or both tokens in the swap pair are on the unsupported token list, no quote will be returned. Note that all tokens do not necessarily have regular or sufficient liquidity to perform a swap between any two tokens at any volume. We always recommend submitting a quote request prior to performing a swap to confirm that there is an available route, or filler, to complete the swap and available liquidity. We recommend that end users always do their own due diligence before swapping any tokens.

​
Supported Tokens for Bridging

To get a list of tokens which can be bridged, and the chains between which they can be bridged, please make a request to the swappable_tokens endpoint.

​
How Often are New Tokens Added

As new tokens are created they are automatically detected and made available for swapping within minutes of creation. New tokens may not be immeidately swapable as it is dependent on their being sufficient liquidity in a pool for swapping to take place. The Verified tokens list is updated periodically as new tokens are supported by major centralized exchanges.
