Cross-Chain Bridges Refocus on Security After Multi-Year Loss Toll
Bridge protocols continue to redesign around lighter trust assumptions after cumulative exploit losses in the billions.
Cross-chain bridges have continued to redesign around lighter trust assumptions, following cumulative exploit losses running into billions of dollars over recent years. Newer designs from LayerZero, Wormhole, Chainlink CCIP and Across have all leaned on either restaked collateral, zero-knowledge proofs or optimistic verification models.
Analysts at Chainalysis and Immunefi note that headline bridge exploits have become less frequent in recent quarters, though sophisticated address-poisoning and phishing campaigns targeting bridge users have partially replaced protocol-level breaches as the dominant loss vector.
Interoperability standards including ERC-7683 and ERC-7786 have gained traction as attempts to unify user experience across bridge providers.
