Dust Limit
policy · fee
The minimum output value a node or miner relays because smaller outputs cost more to spend than they are worth.
1.definition
The dust limit is a relay or wallet policy threshold for uneconomic outputs. Outputs below this value are usually nonstandard because spending them would require more in fees than their value, creating UTXOs that burden wallets and nodes.
2.note
- Exact thresholds vary by chain and policy rules
- Wallets typically prevent creating dust outputs
