Struct ExitFeeEstimate 

pub struct ExitFeeEstimate {
    pub exit_broadcast_fee: Amount,
    pub claim_fee: Amount,
    pub fee_rate: FeeRate,
    pub txs_to_broadcast: usize,
    pub fundable: bool,
}

A breakdown of the estimated onchain cost of unilaterally exiting a set of VTXOs.

exit_broadcast_fee is paid now from confirmed onchain funds; claim_fee is paid later out of the recovered value. Use ExitFeeEstimate::total for the sum. See fee_rate for how each leg is priced.

Fields

exit_broadcast_fee: Amount

The total fees required to broadcast every not-yet-confirmed exit transaction.

This is the minimum offchain-balance required to pay for an emergency exit.

claim_fee: Amount

Fee for transaction that drains the exit outputs. It is substracted from the exited VTXO amount.

fee_rate: FeeRate

The fee rate used to price the exit-broadcast (CPFP) leg. Unless an explicit fee rate was supplied, the claim leg is priced separately at the chain’s regular rate, so this is not necessarily the rate behind claim_fee.

txs_to_broadcast: usize

The number of exit transactions that still need to be broadcast and CPFP-bumped.

fundable: bool

Whether the wallet’s current confirmed onchain balance covers the full exit-broadcast walk.

A unilateral exit is funded serially across confirmed UTXOs (a CPFP child can only spend confirmed coins, so each bump’s change must confirm before it can fund the next one). An exit can therefore stall midway if confirmed funds run short even when a single per-step fee looks affordable. The walk is simulated bump by bump against a replica of the wallet; false means confirmed funds ran out partway through it.
