What are Dust Transactions?
Dust, in cryptocurrency language, is used to specify the tiny, in some cases almost negligible, amount of coins or tokens left after making a transaction. The dust value in monetary terms could be anywhere from as low as a fraction of a cent to a few dollars. Usually, the dust in a dust transaction is less than the fee that will be paid to transfer it. However, it should be noted that a universal threshold for dust is not set; hence different participants may set different dust thresholds.
Generally, any amount which is less than the transaction fee could be considered to be a dust. Dust can be identified on popular public blockchains such as Bitcoin, Dogecoin, Bitcoin Cash, etc. Some exchanges allow users to convert the dust, although it cannot be traded because there is a defined minimum trading size.
