### `sarosDlmm`

*Variable* · `sdk/dist/svm/venues/saros-dlmm/index.d.ts`

Family facade for the recipe orchestrator (ladder-only - no v1 adapter).

```typescript theme={null}
sarosDlmm: {
    slug: string;
    programId: Address<"1qbkdrr3z4ryLA7pZykqxvxWPoeifcVKo6ZG9CfkvVE">;
    tokenProgram: Address<"TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA">;
    fetchPoolConfig: typeof fetchSarosDlmmConfig;
}
```

### `pairArrayIndexes`

*Function* · `sdk/dist/svm/venues/saros-dlmm/index.d.ts`

The two bracketing bin-array indices for `activeId` - matching the real
program's own swap-account convention (cross-validated: the pair chosen
this way is exactly what a real swap accepts, both directions, at every
tested size - see the module header). `lowerIndex < upperIndex` always;
both cover `SAROS_DLMM_MAX_BINS` worth of headroom on either side of
`activeId` (256-bin arrays, an 8-bin walk never needs a third array).

```typescript theme={null}
export declare function pairArrayIndexes(activeId: number): [
    number,
    number
];
```

### `priceFromId`

*Function* · `sdk/dist/svm/venues/saros-dlmm/index.d.ts`

```typescript theme={null}
export declare function priceFromId(binId: number, binStep: number): bigint;
```

### `fetchSarosDlmmConfig`

*Function* · `sdk/dist/svm/venues/saros-dlmm/index.d.ts`

Fetch + gate one Saros DLMM pair (see the module header for the gate list)
and freeze both directions' bin windows. Read-only against the loader.

```typescript theme={null}
export declare function fetchSarosDlmmConfig(load: AccountLoader, pair: Address): Promise<SarosDlmmPoolConfig>;
```

### `SAROS_DLMM_MEMO_PROGRAM`

*Variable* · `sdk/dist/svm/venues/saros-dlmm/index.d.ts`

```typescript theme={null}
MEMO_PROGRAM: Address<"MemoSq4gqABAXKb96qnH8TysNcWxMyWCqXgDLGmfcHr">
```

### `SarosDlmmBin`

*Interface* · `sdk/dist/svm/venues/saros-dlmm/index.d.ts`

```typescript theme={null}
export interface SarosDlmmBin {
    arrayIndex: 0 | 1;
    offset: number;
    binId: number;
    price: bigint;
}
```

### `SarosDlmmWindow`

*Interface* · `sdk/dist/svm/venues/saros-dlmm/index.d.ts`

```typescript theme={null}
export interface SarosDlmmWindow {
    binArrayLower: Address;
    binArrayUpper: Address;
    lowerIndex: number;
    upperIndex: number;
    bins: SarosDlmmBin[];
}
```

### `SarosDlmmPoolConfig`

*Interface* · `sdk/dist/svm/venues/saros-dlmm/index.d.ts`

```typescript theme={null}
export interface SarosDlmmPoolConfig extends PoolConfig {
    venue: typeof SLUG;
    direction: "xToY" | "yToX";
    tokenXMint: Address;
    tokenYMint: Address;
    vaultX: Address;
    vaultY: Address;
    binStep: number;
    activeId: number;
    baseFactor: number;
    variableFeeControl: number;

        xToY: SarosDlmmWindow;
        yToX: SarosDlmmWindow;
    };
