Cross-chain bridges allow assets and messages to travel between chains that cannot directly verify each other. Bridge designs trade off security, speed, and capital efficiency: canonical bridges (Optimism, Arbitrum) inherit L1 security; liquidity bridges (Stargate, Hop) front capital for instant transfers; intent bridges (Across, deBridge) use solver auctions for the best execution.
