# svm: Arguments

> Arguments: 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`.

### `encodeArgSlot`

*Function* · `@eco-incorp/sauce/svm`

Encodes one runtime value against its layout slot (scalar → 32B BE word, bytes → raw).

```typescript theme={null}
export declare function encodeArgSlot(slot: ArgsLayoutSlot, value: ArgValue): Uint8Array;
```

### `encodePayloadArgs`

*Function* · `@eco-incorp/sauce/svm`

Encodes the full payload-args tail against the caller-supplied `ArgsLayout`: slot i's
bytes land at exactly layout.slots\[i].offset, back to back - the compiled
prologue's baked SLICE offsets leave no room for drift, so any layout/value
mismatch throws instead of producing silently shifted reads.

```typescript theme={null}
export declare function encodePayloadArgs(layout: ArgsLayout, values: readonly ArgValue[]): Uint8Array;
```
