DeFi now spans dozens of networks. Cross-chain bridges and swaps let you move assets between chains, accessing opportunities across the multi-chain ecosystem.
How Bridges Work
Bridges lock assets on the source chain and mint representations on the destination. Different bridges use different security models—trusted validators, cryptographic proofs, or optimistic verification with fraud proofs.
Bridge Options
- Native bridges (Arbitrum, Optimism) – Highest security, longer withdrawal times
- Third-party bridges (Hop, Across, Stargate) – Faster, additional trust assumptions
- Aggregators (LI.FI, Socket) – Route through optimal paths automatically
Security Best Practices
Test with small amounts first. Verify destination addresses carefully. Use established bridges with strong track records. Understand the security model before bridging significant value.
Cross-chain capability is increasingly essential as DeFi expands beyond single-chain limitations.
