Bridging Assets
How Bridges Work
- Lock tokens on source chain
- Mint equivalent on destination
- Smart contract manages process
- Takes minutes to hours
Popular Bridges
- LayerZero / Stargate: Omnichain
- Across Protocol: Fast bridging
- Portal (Wormhole): Multi-chain
- Official chain bridges
Bridge Safety
- Bridges are frequent hack targets
- Use established bridges only
- Start with small test amounts
- Verify destination addresses
- Check bridge TVL and audit status
Cross-Chain Strategies
Arbitrage
- Same token, different prices across chains
- Factor in bridge fees and time
- Speed is critical
- Diminishing opportunities
Yield Optimization
- Farm yields on chain with best rates
- Move capital to highest APY
- Consider bridge costs
- Net yield after fees matters
New Chain Opportunities
- Early protocols on new chains
- Airdrop farming across chains
- Lower competition initially
- Higher risk on new chains
Portfolio Across Chains
- Track positions on all chains
- Use portfolio trackers (DeBank, Zapper)
- Keep gas tokens on each chain
- Secure each chain separately
- Document bridge transactions for taxes
