# Reference: `sushi/svm` Chain

The SVM chain module exposes SVM-only chain metadata.

| Export | Purpose |
|---|---|
| `svmChains`, `svmChainIds` | Known SVM chains and IDs. |
| `SvmChainId` | Enum-like SVM chain ID lookup. |
| `isSvmChainId`, `getSvmChainById` | Guard and lookup by ID. |
| `SvmMainnetChainId`, `isSvmMainnetChainId` | Mainnet type and guard. |
| `SvmChainKey`, `isSvmChainKey`, `getSvmChainByKey` | Chain key type, guard, and lookup. |
| `defineSvmChain` | Define an SVM chain object. |

```ts twoslash
import { SvmChainId, getSvmChainById } from 'sushi/svm'

const solana = getSvmChainById(SvmChainId.SOLANA)
```
