Transaction Cross-Test (examples/txtest)

This directory contains a small integration test that guarantees the Go and TypeScript implementations of the Keymaster multisig pool create bit-identical transactions from the same fixture data.

Contents

Prerequisites

• Go 1.20+
• Bun ≥ 1.0 (for running TypeScript)
• Node dependencies installed (bun install at project root)

Running the test

From the project root:

# 1. Generate TS transactions (optional – useful while debugging)
bun run examples/txtest/ts_runner.ts

# 2. Generate Go transactions (optional)
go run examples/txtest/go_runner/main.go

# 3. One-shot comparison (recommended)
go run examples/txtest/compare.go

Expected output on success:

PASS: Go and TS transactions are identical

If you see FAIL, the program will show the differing Step hex so you can diff them and locate the root cause (signature hash, script, fee, etc.).

Debug Tips

• Both runners print the generated signature-hash preimage (TS sighash:) and its double-SHA256 digest (sighash32). Comment out these console.log / fmt.Printf lines or guard them with an environment variable when you no longer need verbose output.
• Keep compare.go in your CI pipeline to ensure future changes maintain byte-level parity between languages.
