…handling Adds Transaction and ZcashTransaction wrapper classes to provide a clean, typed API over the WASM bindings. Extracts Zcash transaction parsing logic into a separate module for better reusability, making the implementation more modular and maintainable. Issue: BTC-2659 Co-authored-by: llm-git <llm-git@ttll.de>
Add support for Dash transactions, including special transaction format used for Evolution (EVO) features. This implementation: - Adds parser/serializer for Dash transaction format with extra payload - Implements DashTransaction class for round-trip processing - Extends PSBT handling to support Dash's transaction format - Adds unit tests with fixtures to verify correct handling Issue: BTC-2659 Co-authored-by: llm-git <llm-git@ttll.de>
Add test cases to verify proper handling of large Dogecoin values (up to 1e19). This ensures PSBT creation, signing, and extraction work correctly with amounts that exceed JavaScript's safe integer limits but fit in u64. Issue: BTC-2659 Co-authored-by: llm-git <llm-git@ttll.de>
Add Dash support to WASM package by creating a new module and exposing the Dash transaction wrapper for JavaScript interoperability. Issue: BTC-2659 Co-authored-by: llm-git <llm-git@ttll.de>
