Curve Finance Suspends LayerZero Cross-Chain Bridging Function in Response to rsETH Infrastructure Hack

2026-04-20 by admin

Deep Tide TechFlow News, April 20th: According to an official announcement from Curve Finance, due to a hack on the rsETH LayerZero infrastructure, Curve Finance has announced a suspension of its LayerZero infrastructure for security reasons, with resumption pending further investigation into the root cause. This suspension affects: CRV cross-chain bridging functionality from chains such as BNB Chain, Sonic, Avalanche, Fantom, Etherlink, and Kava (chains using native bridging are unaffected), as well as crvUSD fast bridging functionality (L2 slow bridging remains operational). Meanwhile, it is reported that KelpDAO also suffered a vulnerability attack, involving approximately $291 million, with specific losses still under investigation.

PANews, June 22 – According to Blockaid monitoring, Taiko’s ERC20 Vault on Ethereum was attacked, resulting in a loss exceeding $1 million. The root cause of the vulnerability lies in a flaw in the source signal proof verification of the Taiko cross-chain bridge, where a fabricated message proof was accepted as valid on Ethereum L1 without a corresponding legitimate MessageSent event on the Taiko source chain. This allowed the attacker to register and extract fraudulent cross-chain messages, thereby releasing assets from the ERC20 Vault without authorization.
