Native currency fees for mining / validating transactions

Question

Hi Multichain folks,

I have a few questions when it comes to native currency fees. when using api calls like sendassetfrom and issuefrom:

1. does the wallet calculates the fee required according to the minimum-relay-fee, how is the fee calculated
2. does the wallet then add the change output for the inputs - fee?
3. the unclaimed native currency (input - change output) gets picked up by the mining/validating node address

Thanks.

Answer 1

Thanks, to answer your questions:

1. Yes, the wallet calculated the fee automatically based on transaction size and the minimum-relay-fee.
2. Yes, the wallet adds a change output – in fact even without fees a change output is always added, because the wallet needs a UTXO to spend for the next transaction.
3. Yes, any unclaimed native currency gets collected by the block miner, just as in bitcoin.
