```

### `USDC_USD_PYTH_FEED`

*Variable* · `sdk/dist/svm/venues/hylo/index.d.ts`

```typescript theme={null}
USDC_USD_PYTH_FEED: Address<"6HAuqASbHEh4w4REJEUUUCginTLfj1kwCh215ZLtMkrT">
```

```typescript theme={null}
HYLO_ACCOUNT_SIZE = 511
```

### `HYLO_DISCRIMINATOR`

*Variable* · `sdk/dist/svm/venues/hylo/index.d.ts`

sha256('account:Hylo')\[0..8].

```typescript theme={null}
HYLO_DISCRIMINATOR: number[]
```

### `USDC_PAIR_ACCOUNT_SIZE`

*Variable* · `sdk/dist/svm/venues/hylo/index.d.ts`

```typescript theme={null}
USDC_PAIR_ACCOUNT_SIZE = 173
```

### `USDC_PAIR_DISCRIMINATOR`

*Variable* · `sdk/dist/svm/venues/hylo/index.d.ts`

sha256('account:UsdcPair')\[0..8].

```typescript theme={null}

```

### `hylo`

*Variable* · `sdk/dist/svm/venues/hylo/index.d.ts`

```typescript theme={null}
hylo: SvmVenueAdapter
```

### `hyloGate`

*Function* · `sdk/dist/svm/venues/hylo/index.d.ts`

Prepare-time SELF-DROP gate (see module header GATES): pause state (recoverable) and the
USDC/USD Pyth oracle's own validity (verification level, confidence, staleness vs `now` - mirrors `hylo_core::pyth::query_pyth_oracle` except the `posted_slot` sub-check, which needs
the live SLOT this hook does not receive - disclosed narrower-than-real-gate residual). All
from the FETCH-TIME snapshot (this hook has no loader) - a live CPI still enforces the real,
current state regardless (SVM execution-time re-check is a platform impossibility).

```typescript theme={null}
export declare function hyloGate(cfg: PoolConfig, now: bigint): void;
```

### `hyloMintOut`

*Function* · `sdk/dist/svm/venues/hylo/index.d.ts`

TS mirror of the emitted mint (aToB) fragment.

```typescript theme={null}
export declare function hyloMintOut(live: HyloLiveState, priceScale: bigint, x: bigint): bigint;
```

### `hyloRedeemCapacity`

*Function* · `sdk/dist/svm/venues/hylo/index.d.ts`

The redeem-direction input cap (see module header CAPACITY) - 0 when the pool is unquotable.

```typescript theme={null}
export declare function hyloRedeemCapacity(live: HyloLiveState, priceScale: bigint): bigint;
```

### `hyloRedeemOut`

*Function* · `sdk/dist/svm/venues/hylo/index.d.ts`

TS mirror of the emitted redeem (bToA) fragment - `x` already clamped to the capacity above.

```typescript theme={null}
export declare function hyloRedeemOut(live: HyloLiveState, priceScale: bigint, x: bigint): bigint;
```

### `SvmHyloDriftError`

*Class* · `sdk/dist/svm/venues/hylo/index.d.ts`

Recoverable live-state drift (pause / stale-or-low-confidence oracle) between discovery and
prepare - the SAME class `the consuming app SVM solver entry`'s own `SvmWindowDriftError` names (that class
is private to index.ts, so this venue module carries an identically-treated local marker;
`the consuming app SVM solver entry`'s FAMILIES wiring re-throws this as its own `SvmWindowDriftError` so the
self-drop classification stays centralized there).

```typescript theme={null}
export declare class SvmHyloDriftError extends Error {
}
```

### `HyloPoolConfig`

*Interface* · `sdk/dist/svm/venues/hylo/index.d.ts`

```typescript theme={null}
export interface HyloPoolConfig extends PoolConfig {
    venue: typeof SLUG;
    direction: "aToB" | "bToA";
    priceScale: bigint;
    protocolPausedAtFetch: boolean;
    pairPausedAtFetch: boolean;
    verificationTagAtFetch: number;
    priceRawAtFetch: bigint;
    confRawAtFetch: bigint;
    publishTimeAtFetch: bigint;
    intervalSecsAtFetch: bigint;
    confToleranceBitsAtFetch: bigint;
}
