# Supported Chains

> Chain identifiers and swap provider coverage for composable actions

## Chain identifiers

Chain identifiers are either **names** or **chain IDs**. The following names are accepted wherever a `ChainIdentifier` is expected (`useQuote`, the action builders, `useEarnMarkets`, `uniswapV3.onChain(...)`, …):

```
apechain, arbitrum, arbitrum-nova, avalanche, avalanche-c, b3,
base, binance, bsc, bnb, etherlink, gnosis, hyperevm, katana,
mainnet, ethereum, monad, optimism, polygon, soneium, somnia,
sonic, xai
```

Chain IDs (e.g. `8453` for Base, `42161` for Arbitrum) work interchangeably.
