What is Dust?
In the language of cryptocurrencies, the term dust refers to a tiny amount of coins or tokens.
The Bitcoin (BTC) protocol sometimes needs to generate tiny output of coins when users send Bitcoin back and forth. Other UTXO blockchains that are forked from Bitcoin exhibit this same tiny outputs, namely Bitcoin Cash (BCH), Litecoin (LTC) and Dogecoin (DOGE).
Why does a Dust Error occur?
As explained further on the article about UTXO (Unspent Transaction Output), there are unspent output transactions that are generated whenever a transaction is made. These coins that are so small in value that they require more fees to spend than they’re actually worth.
Data storage does not come free, and the network requires some time to process, verify and include individual transactions in the network. This slows down the network and creates costs to those who run Bitcoin servers. And thus, to prevent the network from being “spammed”, these transactions get ignored on the network and returns as an error.
What can I do?
Do not send small transactions with a higher fee. Since the network will attempt to create a UTXO from a small transaction, the transaction will fail.
Try adding more funds first to the wallet before sending them all out. Having a larger transaction will ensure that the network accepts the transaction right away.
Lower the transaction fee. Before you send the transaction, you can adjust the byte price.
Leave a considerable amount on the wallet so that the network will not consider it as a dust transaction. The remaining balance will not be flagged as a dust UTXO.
