  * horizons.

+ * If access to a local mempool is not feasible, feerate estimates should be fetched from a set of
+ * third-parties hosting them. Note that this enables them to affect the propagation of your
+ * pre-signed transactions at any time and therefore endangers the safety of channels funds. It
+ * should be considered carefully as a deployment.

  * Note that all of the functions implemented here *must* be reentrant-safe (obviously - they're
  * called from inside the library in response to chain events, P2P events, or timer events).

+ * LDK may generate a substantial number of fee-estimation calls in some cases. You should
+ * pre-calculate and cache the fee estimate results to ensure you don't substantially slow HTLC
+ * handling.
