I’ve implemented BIP-322 signature verification in a production DeFi protocol and ran comprehensive security testing.
Implementation Details:
- Protocol: ReserveBTC (Bitcoin-backed DeFi on MegaETH)
- Use case: Verify Bitcoin address ownership without custody
- Scale: Production-ready for 10,000+ users
Security Test Results:
✅ 32/32 tests passed (100%)
✅ 0 vulnerabilities found
Test breakdown:
- Cryptographic attacks: 8/8 passed
- Injection attacks: 7/7 passed
- Input validation: 12/12 passed
- Protocol compliance: 3/3 passed
- DoS prevention: 1/1 passed
- Legitimate operations: 1/1 passed
Supported address types:
- P2WPKH (bc1q…, tb1q…)
- P2TR (bc1p…)
- P2SH-P2WPKH (3…)
- P2PKH (1…)
Open source:
Questions:
- Are there any edge cases beyond standard test vectors I should validate?
- Any recommendations for production BIP-322 deployments?
- Would contributing our test vectors be useful to the community?
Happy to share implementation details or test cases!
