currentHeight

abstract fun currentHeight(height: UInt): TxBuilder(source)

Set the current blockchain height.

This will be used to:

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

  2. 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.
