Wrapper around hwi, such that one can sign bdk PSBTs directly
Project description
Wrapper around hwi, such that one can sign bdk PSBTs directly
-
This provides an abstraction layer ontop of hwi, such that only bdk is needed from the outside
-
Currently supported are
- Coldcard
-
It also provides
- AddressTypes, which are the commonly used bitcoin output descriptor templates
- seed_tools.derive_spk_provider to derive xpubs from seeds for all AddressTypes (bdk does not support multisig templates currently https://github.com/bitcoindevkit/bdk/issues/1020)
- SoftwareSigner which can sign single and multisig PSBTs, this doesn't do any security checks, so only use it on testnet
Demo
Run the demo with
python demo.py
Tests
Run tests
python -m pytest -vvv --log-cli-level=0
Library Usage
- For xpub derivation bip_utils is used
- For signing a psbt python-bitcointx is used
