How to generate vanity seed fingerprints, bitcoin addresses, and txids

Note: This is all just for educational / fun purposes. Do not use this code to generate a real seed that you intend to store real value on!!

Setup

Create a python3 virtualenv and install the one dependency:

pip install embit

kdmukai

from binascii import a2b_base64, unhexlify
from copy import deepcopy
from io import BytesIO

from embit.networks import NETWORKS
from embit.psbt import PSBT, OutputScope

# one input, one external recipient + change
psbt_base64 = "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"
