Lido added direct Ethereum staking from Arbitrum, Base, Linea and Optimism to its own interface on Thursday, removing a step that previously forced users to bridge ETH to mainnet before they could stake it.
"Direct staking on Ethereum L2s is live via the Lido UI," the protocol wrote on X. "Stake ETH on Arbitrum, Base, Linea & Optimism in just a few clicks, all without manually bridging to Ethereum and back. Powered by Chainlink CCIP."
The feature is live now at stake.lido.fi.
Lido explained the mechanics in a follow-up post:
"Your ETH is exchanged for wstETH from a dedicated liquidity pool on the same L2, using a Chainlink price feed that reflects the exchange rate provided by the Lido protocol. Behind the scenes, ETH is automatically bridged to Ethereum and staked through Lido, with wstETH returned to replenish the pool."
What actually happens behind the one-click flow
The staking itself still takes place on Ethereum mainnet, where Lido's protocol has handled ETH staking since launch. What changes is the path to get there. A user on an L2 deposits ETH into a liquidity pool that already holds wstETH, the non-rebasing wrapped version of stETH whose token balance stays fixed while its underlying value rises with accrued staking rewards. The pool hands over wstETH immediately, priced using a Chainlink feed that tracks Lido's actual exchange rate rather than whatever rate a decentralized exchange happens to be quoting at that moment. Separately, and without the user waiting on it, the deposited ETH gets bridged to mainnet and staked through Lido, with the resulting wstETH sent back to refill the same pool for the next user.
Chainlink's Cross-Chain Interoperability Protocol carries the ETH over to mainnet, while each network's own native bridge handles the return trip for wstETH. Lido's technical fee documentation states that the cost of replenishing the pool comes from a separately funded contract balance rather than being deducted from what stakers deposit, and users still pay standard L2 gas fees for their transaction.
This isn't Lido's first attempt at cutting out the bridge step
Lido had already built this cross-chain staking rail once before, just not inside its own interface. The protocol introduced the underlying infrastructure in October 2024 for Arbitrum, Base and Optimism, but access ran exclusively through third-party frontends, including XSwap, OpenOcean and Interport. Linea support followed in October 2025, also through outside interfaces before this week's update. Thursday's launch is the first time Lido has offered this flow directly through its own stake.lido.fi site, rather than asking users to trust and navigate a separate platform to reach it.
That history matters for anyone judging how mature this feature actually is. The routing logic, the pool-based liquidity model and the Chainlink price feed have already run in production for roughly a year across three of these four networks, which gives the system more of a track record than a brand new integration would carry.
Why liquidity depth decides how fast the swap feels
Chainlink's integration guide instructs frontends to read each pool's configured fee before calculating a quote, and the one-click experience only works as advertised when the local wstETH pool holds enough tokens to cover the deposit. Lido's interface can flag a warning when a deposit outsizes available liquidity, pointing users toward a wait of roughly an hour while the pool refills through the mainnet bridge round trip.
That liquidity dependency is the same tradeoff that shows up across most liquid staking and cross-chain bridging products built around pooled reserves rather than instant mint-and-burn mechanics. Networks like Across and Stargate rely on comparable liquidity-pool models for fast cross-chain transfers, and all of them share the same weakness, a large enough transaction can temporarily drain a pool faster than it refills, which pushes the user from an instant swap into a slower settlement path. For most retail-sized ETH deposits this should stay invisible, but users moving larger amounts should expect the wait-time warning to show up more often, particularly on networks where Lido's pool liquidity is thinner.
Lido's stETH currently represents the largest liquid staking position on Ethereum, with the protocol's own statistics page showing more than 9.6 million ETH staked and a stETH market capitalization above $22.7 billion. That scale gives Lido both the liquidity base to support pooled cross-chain swaps and the incentive to keep reducing friction for L2-based users, who represent a growing share of where Ethereum activity actually happens day to day.
