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