Class FeeEstimator


  • public class FeeEstimator
    extends Object
    A trait which should be implemented to provide feerate information on a number of time 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).
    • Method Detail

      • destroy

        public void destroy()
        Destroys the object, freeing associated resources. After this call, any access to this object may result in a SEGFAULT or worse. You should generally NEVER call this method. You should let the garbage collector do this for you when it finalizes objects. However, it may be useful for types which represent locks and should be closed immediately to avoid holding locks until the GC runs.
      • get_est_sat_per_1000_weight

        public int get_est_sat_per_1000_weight​(ConfirmationTarget confirmation_target)
        Gets estimated satoshis of fee required per 1000 Weight-Units. LDK will wrap this method and ensure that the value returned is no smaller than 253 (ie 1 satoshi-per-byte rounded up to ensure later round-downs don't put us below 1 satoshi-per-byte). The following unit conversions can be used to convert to sats/KW: satoshis-per-byte * 250 satoshis-per-kbyte / 4
