* Add fee estimation to wallet * Add fee rate to kaspawallet parse * Update go version * Get rid of golint * Add RBF support to wallet * Fix bump_fee UTXO lookup and fix wrong change address * impl storage mass as per KIP9 * Use CalculateTransactionOverallMass where needed * Some fixes * Minor typos * Fix test * update version * BroadcastRBF -> BroadcastReplacement * rc3 * align proto files to only use camel case (fixed on RK as well) * Rename to FeePolicy and add MaxFee option + todo * apply max fee constrains * increase minChangeTarget to 10kas * fmt * Some fixes * fix description: maximum -> minimum * put min feerate check in the correct location * Fix calculateFeeLimits nil handling * Add validations to CLI flags * Change to rc6 * Add checkTransactionFeeRate * Add failed broadcast transactions on send error` * Fix estimateFee change value * Estimate fee correctly for --send-all * On estimateFee always assume that the recipient has ECDSA address * remove patch version --------- Co-authored-by: Michael Sutton <msutton@cs.huji.ac.il>
