Cross-chain bridges remain critical but fragile components of DeFi. In 2025, they still represent one of the largest attack surfaces, with billions in TVL exposed. Bridges are essential for liquidity migration, yet hacks have repeatedly eroded confidence. As ecosystems fragment, reliance on bridges grows, raising systemic risk. A major exploit could cascade across chains, triggering liquidity freezes and price shocks. While solutions like native interoperability and message-passing protocols are emerging, bridges remain the weakest link. Investors must assess whether liquidity concentration in cross-chain hubs creates the next black swan risk.
