# svm: Clusters

> Clusters: the declaration and description of each of the 2 exports of @eco-incorp/sauce/svm.

`@eco-incorp/sauce/svm` is the Solana side: the client (`createSauceSvmClient`), clusters, PDAs, account resolution against the compiler's account manifest, Kitchen and engine instructions, transactions and sending, token accounts, and compute planning for `@sauce/router`'s Solana venues. `@eco-incorp/sauce/svm/engine` exports the engine's wire format and instruction builders, `@eco-incorp/sauce/svm/verify` verifies settle programs and engine CPI data, and `@eco-incorp/sauce/svm/engine-artifacts` (Node only) returns file paths to the packaged engine and Kitchen binaries.

```typescript theme={null}
import { createSauceSvmClient, SOLANA_CLUSTERS } from "@eco-incorp/sauce/svm";
```

Generated from the type declarations of `@eco-incorp/sauce`.

### `SolanaCluster`

*Interface* · `@eco-incorp/sauce/svm`

Solana cluster definition (parallel to the EVM `Chain` registry in chains/).

Carries no RPC endpoint: the SDK ships none. Pass your cluster's URL as `rpcUrl` to
`createSauceSvmClient`.

```typescript theme={null}
export interface SolanaCluster {
    cluster: "mainnet-beta" | "devnet" | "testnet" | "localnet";
    engineChainId: bigint;
    engineProgramId?: Address;
}
```

### `SOLANA_CLUSTERS`

*Variable* · `@eco-incorp/sauce/svm`

```typescript theme={null}
SOLANA_CLUSTERS: Record<SolanaCluster["cluster"], SolanaCluster>
```
