feat(wasm-utxo): add BitGoPsbt.getUnsignedTransaction()#284
Merged
Conversation
Adds get_unsigned_tx_bytes() to the BitGoPsbt Rust core, a #[wasm_bindgen] get_unsigned_tx() wrapper in the wasm layer, and getUnsignedTransaction() in the TypeScript BitGoPsbt class. Unlike extractTransaction(), the new method does not require finalization or partial signatures — it serializes the raw unsigned transaction embedded in the PSBT global map, equivalent to utxo-lib's UtxoPsbt.getUnsignedTx().toBuffer().
