A dust transaction refers to the transfer of a very small amount of cryptocurrency, often less than the network fee required to process the transaction. These tiny amounts, known as “dust,” may be left in a wallet after making transactions, and are often too insignificant to be spent because the cost to send them outweighs their value.Dust transactions are typically used in specific contexts, such as privacy strategies. By mixing small amounts of coins with larger ones, a user can obscure the source of funds. However, they can also clutter a wallet, making it more complex to manage balances.On some networks, dust transactions can create operational challenges. They might lead to bloated blockchain sizes and increased transaction fees when trying to consolidate or spend these small amounts later on. Some users might even choose to ignore these trivial amounts instead of incurring additional costs to move them.
