estimatesmartfee conf_target ( "estimate_mode" )
Estimates the approximate fee per kilobyte needed for a transaction to begin
confirmation within conf_target blocks if possible and return the number of blocks
for which the estimate is valid. Uses virtual transaction size as defined
in BIP 141 (witness data is discounted).
Arguments:
1. conf_target (numeric, required) Confirmation target in blocks (1 - 1008)
2. estimate_mode (string, optional, default="economical") The fee estimate mode.
unset, economical, conservative
unset means no mode set (default mode will be used).
economical estimates use a shorter time horizon, making them more
responsive to short-term drops in the prevailing fee market. This mode
potentially returns a lower fee rate estimate.
conservative estimates use a longer time horizon, making them
less responsive to short-term drops in the prevailing fee market. This mode
potentially returns a higher fee rate estimate.
Result:
{ (json object)
"feerate" : n, (numeric, optional) estimate fee rate in BTC/kvB (only present if no errors were encountered)
"errors" : [ (json array, optional) Errors encountered during processing (if there are any)
"str", (string) error
...
],
"blocks" : n (numeric) block number where estimate was found
The request target will be clamped between 2 and the highest target
fee estimation is able to return based on how long it has been running.
An error is returned if not enough transactions and blocks
have been observed to make an estimate for any number of blocks.
