Search for tx in mnemonics

main.sh

#!/bin/bash

# given a list of mnemonics, try to find tx count for each address in:
# - derivation path 44, 49 and 84:
#   - locking script p2pkh, p2wpkh, p2shwpkh and p2tr

# requires hal (https://github.com/stevenroose/hal)
# requires jq (https://jqlang.github.io/jq/)

# example usage:
# ./main.sh "embrace traffic prepare fatigue burger hood shed comic royal whisper sibling suspect silver spoon erupt edge top squirrel ancient seek start noble window autumn" "other mnemonic..."

# font colors
GREEN='\033[0;32m'
