Bridge Considerations
Security
- - Native bridges (Superbridge) are the most secure
- Third-party bridges rely on their own security models
- Always verify contract addresses before bridging
Timing
- - Native L1→L2 bridges: ~15-20 minutes
- L2→L1 withdrawals: 7 days (challenge period)
- Third-party bridges: varies (minutes to hours)
Fees
- - Native bridges: gas fees only
- Third-party bridges: gas + bridge fees
Dependencies
CODEBLOCK2
For LI.FI integration:
CODEBLOCK3
