### Added

- Add shared snap state helpers `IStateManager`, `State`, and `InMemoryState` (Tron-style write mutex plus blob/path locking). ([#288](https://github.com/MetaMask/internal-snaps/pull/288))
- Add shared caching utilities for network snaps ([#287](https://github.com/MetaMask/internal-snaps/pull/287))
- `ICache`, `CacheEntry`, and `TimestampMilliseconds` for describing a generic cache
- `InMemoryCache`, a TTL-backed in-memory cache
- `StateCache`, a cache backed by a snap state manager
- `useCache` and `useCacheUntil` for wrapping functions with fixed-TTL and dynamic-expiry caching
- Add shared proof-of-ownership message parsing utilities, batch request/response structs, and batch request/response types. ([#268](https://github.com/MetaMask/internal-snaps/pull/268))
- Add a `UuidStruct` Superstruct for validating UUID v4 strings. ([#243](https://github.com/MetaMask/internal-snaps/pull/243))
- Add helpers `serialize`, `deserialize`, and `Serializable` for round-tripping `BigNumber`, `bigint`, `Uint8Array`, and `undefined` through snap state ([#197](https://github.com/MetaMask/internal-snaps/pull/197))
