claude-dev-suite embit
Python Bitcoin library by Crypto Advance team. Optimized for embedded contexts — runs on MicroPython.
Repo: github.com/diybitcoinhardware/embit.
Install
pip install embit
For MicroPython: package as frozen module on firmware.
Quick examples
Address generation
from embit import bip32, bip39, networks, script
mnemonic = "abandon abandon abandon ... about"
seed = bip39.mnemonic_to_seed(mnemonic)
root = bip32.HDKey.from_seed(seed)
acc = root.derive("m/84h/0h/0h")
xpub = acc.to_public()
addr = script.p2wpkh(acc.derive("0/0").key).address(networks.NETWORKS["main"])
print(addr)
PSBT
from embit import psbt
psbt_obj = psbt.PSBT.from_string(psbt_b64)
# inspect, sign
for inp in psbt_obj.inputs:
inp.partial_sigs[some_pubkey] = sig_bytes
print(psbt_obj.to_string())

Common pitfalls
- API differences from python-bitcoinlib; not a drop-in replacement.
- MicroPython port has subset of features; verify before relying.
