-LDK provides a simple default `KeysManager` implementation that takes a 32-byte seed for use as a BIP 32 extended key and derives keys from that. Check out the [Rust docs](https://docs.rs/lightning/*/lightning/chain/keysinterface/struct.KeysManager.html).

 # Spending On-Chain Funds
 
-When a channel has been closed and some outputs on chain are spendable only by us, LDK provides a `util::events::Event::SpendableOutputs` event in return from `ChannelMonitor::get_and_clear_pending_events()`. It contains a list of `chain::keysinterface::SpendableOutputDescriptor` objects which describe the output and provide all necessary information to spend it.

It contains a list of `sign::SpendableOutputDescriptor` objects which describe the output and provide all necessary information to spend it.
 
 If you're using `KeysManager` directly, a utility method is provided which can generate a signed transaction given a list of `
 SpendableOutputDescriptor` objects. `KeysManager::spend_spendable_outputs` can be called any time after receiving the `SpendableOutputDescriptor` objects to build a spending transaction, including delaying until sending funds to an external destination or opening a new channel. Note that if you open new channels directly with `SpendableOutputDescriptor` objects, you must ensure all closing/destination scripts provided to LDK are SegWit (either native or P2SH-wrapped).
