Lido will directly expand ETH staking to four Layer 2s

Lido announced the integration of direct ETH staking functionality for Arbitrum, Base, Linea, and Optimism Layer 2 networks into its official staking interface, which was announced on October 15. This process is supported by Chainlink's cross-chain interoperability protocol CCIP, allowing users to directly obtain wstETH on the originating network without manually transferring ETH across chains to Ethereum and back.

Lido stated that users' ETH will be exchanged for wstETH through dedicated liquidity pools on the same L2, with the Chainlink price feed reflecting the exchange rate of the Lido protocol rather than the exchange market price. The underlying staking still occurs on the Ethereum mainnet: the ETH deposited by users on L2 will automatically be transferred to Ethereum and staked through Lido, after which wstETH will be sent back to replenish the local liquidity pool. Users receive the wrapped version of stETH, wstETH, which maintains a fixed balance while its value reflects staking rewards.

This functionality integrates existing cross-chain infrastructure into Lido's own interface. Lido previously introduced relevant channels for Arbitrum, Base, and Optimism in October 2024, with third-party frontends including XSwap, OpenOcean, and Interport, while Linea followed up in October 2025. In terms of fees, users will still need to pay L2 transaction gas, and cross-chain costs come from the separately funded contract balance rather than staker deposits;
