Removing dust UTXOs from your wallet using electrum to prevent accidental spending. This example creates an OP_RETURN transaction with the entire dust amount being used as the transaction fee. The transaction fee will be ~3 to 5 sat/vB and may take some time to be confirmed. To prevent linking between multiple dust transactions, wait at least until the transaction is confirmed before submitting another.
