unlocking
open override fun unlockingScript(flatTx: ByteArray, inputIdx: Long, sigHashType: ByteArray, inputAmount: Long, spendingProposal: SpendingProposal?): SatoshiScript
Create a spend (input) script that will satisfy the constraints specified by the lockingScript and the templateScript (if applicable). This script will contain the redeemScript in the P2SH case. Many scripts require signatures. This API provides the data needed for this class to craft signatures, and provides additional derived-class defined params.
Parameters
spending
If this destination requires additional information to spend (atomicSpending == false), you cannot successfully call unlockingScript until you have a completed SpendingProposal
