Just a friendly reminder to get your coins off exchanges such as Coinbase. Exchanges do not have sufficient insurance coverage and alot of people will lose substantial amounts at some point. Don´t be lazy, buy a hardware wallet ¯\_(ツ)_/¯

Wallet design: What to do with dust amounts in change?

I’m working on some quirks of a wallet I’m developing, and one of the issues is what to do with change amounts that are larger than dust ~600 satoshis, but less than a practical amount to be sent again with a fee. Should I return the near-dust amount as change, or just tack it on as additional mining fees?

For example, let’s say a user spends an amount that after paying to an output and a sufficient fee leaves only 1,000 satoshis as change. Should I send those 1,000 satoshis as change even though 1,000 satoshis is too small to be spent again with a sufficient fee?

Even with fees as low as 10 satoshis per byte with one input and output (P2PKH) you’d need at least 2,000 satoshis for fees.

I’m thinking it might be better to just put the leftover towards additional mining fees if change amount is below a certain threshold, say 3,000 satoshis. An address with just 1,000 satoshis is mostly useless, and would just add to the growing UTXO set that would likely never be spent. Does this approach seem appropriate, or am I “robbing” users of their dust?
