# svm: Clusters

> Clusters: 2 exports of the svm module of @eco-incorp/sauce, including SolanaCluster, SOLANA_CLUSTERS.

`@eco-incorp/sauce/svm` is the Solana side: staging a program through the kitchen, resolving accounts against the compiler's account manifest, building and sending transactions, and verifying settle programs. Solana execution goes through the Kitchen client here; the SDK's SVM route helpers emit a legacy instruction that the released engine does not accept.

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

This page covers `sdk/dist/svm/clusters.d.ts`.

<Note>
  Generated from the type declarations shipped in `@eco-incorp/sauce` 0.99.4. Each entry shows the package authors' JSDoc and declaration for this SDK version. For runtime compatibility and deployed addresses, see [architecture and deployments](/programmable-transactions/sauce/architecture-and-deployments).
