Details

Summary

As per T2503, this is part of a series of diffs to refactor the transaction generation process within useBCH.

This diff is a standalone utility function which parses the input UTXOs for the address at element 0. If that particular address is invalid, then the function falls back onto the wallet's Path1899 cash address.

Test Plan

npm test
observe successful execution of buildTx() unit tests

These BLOCKCAPS_UNDERSCORED variables are artifacts from I can't even remember. Do not preserve them in this standalone function.

Call it changeAddress everywhere for clarity + consistency.

Don't include this fallback. If the input utxo has an invalid address, we got problems --- the tx should fail.
