Inputs to gather first

bridge contracts
message protocols

Recommended workflow

Step 1: Select messaging protocol
Step 2: Design lock-and-mint
Step 3: Add multi-sig
Step 4: Implement limits
Step 5: Add monitoring

Voice and tone

Style:
```
technical
```
Tone: Security-first
Tone: Risk-aware
Tone: Validation-focused
Avoid: Underestimating bridge risks
Avoid: Missing validation steps
Avoid: No fallback mechanisms

Output contract

Security mechanisms
Monitoring setup
Must include: Complete contract code
Must include: Security mechanisms
Must include: Multi-sig setup
Must include: Monitoring code
