# ChainstateManagerOptions Builder for constructing a [`ChainstateManager`](/documentation/BitcoinKernel/ChainstateManager) — configures data paths, worker-thread count, reindex behavior, and in-memory-database flags. ``` final class ChainstateManagerOptions ``` ## Overview Instantiate with a context and a data directory, tune with the setters, then pass to [`init(options:)`](/documentation/BitcoinKernel/ChainstateManager/init(options:)). On Apple platforms, place the data directory inside Application Support with `isExcludedFromBackup = true` — chainstate is reproducible from the network and doesn’t belong in iCloud backups. Wraps the opaque `btck_ChainstateManagerOptions` type; `deinit` calls `btck_chainstate_manager_options_destroy` when the last Swift reference drops.
