Stacks Fees
Fees are used to incentivize miners to confirm transactions on the Stacks blockchain. The fee is calculated based on the estimate fee rate and the size of the raw transaction in bytes. The fee rate is a market determined variable.
At Fordefi, when creating a new Stacks transaction, the user can decide between three different total fee levels: low, medium, high. Those three levels are determined by the node itself, and affected by the network state.
