Definition
The dust limit is a minimum value threshold below which a very small amount of cryptocurrency is treated as too tiny to move economically on a blockchain. It is typically defined in relation to network fees, so that any amount below this limit would cost as much or more in fees to spend than the amount itself is worth.
In Simple Terms
The dust limit is the smallest amount of a coin that is considered practical to send. If a balance is below this limit, it is usually seen as “dust” because paying the network fee to move it would waste most or all of its value.
Context and Usage
The dust limit is commonly mentioned when discussing small on-chain balances, minimum withdrawal amounts, and the economic size of blockchain transfers. It appears in conversations about network fee conditions, how wallets display tiny leftover amounts, and how systems decide whether to combine or ignore very small outputs when preparing or analyzing transactions.
