Lido has partnered with Chainlink to make CCIP the official cross-chain infrastructure for wstETH.

Liquidity staking protocol Lido announced the integration of the Chainlink Cross-Chain Interoperability Standard (CCIP), with the Chainlink CCIP serving as the official cross-chain infrastructure for staking Ethereum (wstETH). Through this integration, all wstETH cross-chain transfers will leverage the Cross-Chain Token (CCT) standard, with security provided by the Chainlink CCIP. Over the next few months, wstETH will be deployed in phases across all 16 chains, with the implementation process involving multiple detailed steps. Furthermore, early expansion of wstETH onto chains such as Plasma, Monad, Ink, and 0G is already underway through CCIP.
