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
- Bitbox02
- Jade
-
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
- HWIQuick to list the connected devices without the need to unlock them
Demo
Run the demo with
python demo.py
Tests

python -m pytest -vvv --log-cli-level=0
