tool to check how your STX p2pkh and p2sh decode use it well it helped me reverse engineer everything from hirosystems

npm install --force modules must always be patched manually......hunt them down and change them with your chainparams.cpp from your coin hex is always 0x and decimal is always the bare number

25 = B 

bitnet io legacy addresses start with a B
segwit with 'bit' prefix 

https://en.bitcoin.it/wiki/List_of_address_prefixes

and 22 is the p2sh hash in decimal
adjust to your network

FOR LEATHER WALLET PATCHING HERE

npm install --force
modify the node_modules exactly the same way for
bitcoinjs-lib
bip32/src/bip32.js
c32check/address.js
c32check/encoding/js
@stacks/transactions/dist/constants.js
@stacks/transactions/dist/esm/constants.js

in the leather source code not the node_modules

nano shared/crypto/bitcoin/bitcoin.network.ts
