-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).

-However, LDK also allows to customize the way key material and entropy are sourced through custom implementations of the `NodeSigner`, `SignerProvider`, and `EntropySource` traits located in `chain::keysinterface`. These traits include basic methods to provide public and private key material, as well as pseudorandom numbers.
