Constructor Detail

Method Detail

• allowDust

   abstract BumpFeeTxBuilder allowDust(Boolean allowDust)

  Set whether the dust limit is checked.

  Note: by avoiding a dust limit check you may end up with a transaction that is non-standard.

• currentHeight

   abstract BumpFeeTxBuilder currentHeight(UInt height)

  Set the current blockchain height.

  This will be used to:

  • Set the nLockTime for preventing fee sniping. Note: This will be ignored if you manually specify a nlocktime using TxBuilder::nlocktime.

  • Decide whether coinbase outputs are mature or not. If the coinbase outputs are not mature at current_height, we ignore them in the coin selection. If you want to create a transaction that spends immature coinbase inputs, manually add them using TxBuilder::add_utxos. In both cases, if you don’t provide a current height, we use the last sync height.

• finish

   abstract Psbt finish(Wallet wallet)

  Finish building the transaction.

  Uses the thread-local random number generator (rng).

  Returns a new Psbt per BIP174.

  WARNING: To avoid change address reuse you must persist the changes resulting from one or more calls to this method before closing the wallet. See Wallet::reveal_next_address.

• nlocktime

   abstract BumpFeeTxBuilder nlocktime(LockTime locktime)

  Use a specific nLockTime while creating the transaction.

  This can cause conflicts if the wallet’s descriptors contain an "after" (OP_CLTV) operator.

• setExactSequence

   abstract BumpFeeTxBuilder setExactSequence(UInt nsequence)

  Set an exact nSequence value.

  This can cause conflicts if the wallet’s descriptors contain an "older" (OP_CSV) operator and the given nsequence is lower than the CSV value.

• version

   abstract BumpFeeTxBuilder version(Integer version)

  Build a transaction with a specific version.

  The version should always be greater than 0 and greater than 1 if the wallet’s descriptors contain an "older" (OP_CSV) operator.
