Gravity Bridge, a cross-chain protocol connecting Ethereum and Cosmos, suffered a security breach resulting in the theft of approximately $5.4 million in assets including USDC, wrapped Ether, USDT, and PAXG. The protocol has been halted for investigation into a suspected signing key compromise.
Cross-chain bridges are critical infrastructure in the decentralized finance (DeFi) ecosystem, enabling the transfer of assets between different blockchain networks. However, their complex architecture and reliance on multi-signature schemes or validator networks make them frequent targets for hackers. The Gravity Bridge exploit highlights the persistent security risks within DeFi, where vulnerabilities in access controls, rather than smart contract code, often lead to significant fund losses.
