What is the main risk of cross-chain bridges?

Bridges have been the largest exploit target in crypto. Bridge security relies on validator sets, multisigs, or optimistic fraud proofs. Ronin ($625M), Wormhole ($320M), and Nomad ($190M) bridge hacks are cautionary examples.

What is the difference between lock-and-mint and liquidity bridge designs?

Lock-and-mint bridges hold tokens on source chain and mint wrapped tokens on destination. Liquidity bridges swap tokens with existing liquidity pools on both sides. Liquidity bridges are faster but limited by pool size.
