Kaspa transaction fee now
A Kaspa fee is the transaction's mass in grams × the fee rate in sompi per gram. Mass counts the transaction's size, its outputs and its signature operations (compute mass); KIP-9 adds a storage mass that grows for very small outputs. A standard payment from one input to two outputs has a compute mass of 2,036 grams.
