Ethereum's liquid staking protocol Lido Finance has paused new bridging deposits after discovering a potential security vulnerability in the wstETH bridging contract on the ZKsync network. Currently, the vulnerability has not been exploited, and user assets are safe. Lido is working on a fix through decentralized governance, with a governance vote expected to take place in late March 2026. This incident has caused short-term pressure on the related tokens.
