Implements Bitcoin message signing and verification according to BIP-137 standard. This adds a new `message` module with `signMessage` and `verifyMessage` functions that work with ECPair keys. Issue: BTC-2866 Co-authored-by: llm-git <llm-git@ttll.de>
Add methods to properly compare BIP32 keys and safely serialize them: - `equals()` method for checking key equality without serialization - `toJSON()` that safely returns xpub even for private keys - Custom Node.js inspect representation for better debugging - Rust implementation of key equality comparison Issue: BTC-2866 Co-authored-by: llm-git <llm-git@ttll.de>
Port test utilities from utxo-core for descriptor wallet testing: - Add fixture handling and object serialization helpers - Add descriptor template functions to create common test descriptors - Add mock PSBT utilities for descriptor wallet testing Issue: BTC-2866 Co-authored-by: llm-git <llm-git@ttll.de>
Adds a new method to PSBT that returns outputs with resolved address strings derived from each output script. This allows getting proper addresses formatted for specific coin networks without needing to call address.fromOutputScript separately for each output. Issue: BTC-2866 Co-authored-by: llm-git <llm-git@ttll.de>
Add a new export for testutils in package.json to allow other modules to import helper functions and test fixtures. Issue: BTC-2866 Co-authored-by: llm-git <llm-git@ttll.de>
