Hi, I’d like to find a standard/preferred way to dispose of “dust attack” UTXOs in on-chain wallets. In particular the dust I’m looking to get rid of are the ones created by an adversary to trick wallet users into revealing common ownership between otherwise unrelated UTXOs. This happens when the adversary sends dust amount UTXOs to all the anonymous on-chain addresses they are interested in and hope that some of these will be unintentionally spent together with an unrelated UTXO. (see 

The best data I could find on the distribution of output sizes in the UTXO set is from 

. But this report focuses on spam meta protocols and doesn’t break out details for dust attack UTXOs which are generally at or around the core dust limit.
