Lido, the largest liquid staking protocol on Ethereum, has extended one-transaction ETH staking to four major Ethereum layer-2 networks: Arbitrum, Base, Linea and Optimism, according to an announcement reported by Crypto Briefing.

The change removes a multi-step workflow that has defined staking for L2 users since the networks launched. Previously, a user on Arbitrum or Base who wanted to stake ETH through Lido had to bridge assets to Ethereum mainnet, execute the staking transaction there, and bridge the resulting liquid staking token back to the L2. Each hop carried fees, settlement delay and bridge risk. The new flow compresses that into a single transaction executed on the L2 itself.

What does this change for L2 users and integrators?

For retail users, the practical difference is cost and latency. A one-transaction flow eliminates two bridge crossings, which on Ethereum mainnet have historically been the dominant friction in small-ticket staking. For decentralized applications built on Arbitrum, Base, Linea and Optimism, the change means staking can be embedded directly into on-chain interfaces — wallets, dashboards, and DeFi front ends — without routing users across chains or requiring them to hold mainnet ETH for gas.

The expansion also widens the distribution surface for Lido's liquid staking tokens across the L2 ecosystem, where decentralized finance activity has migrated steadily over the past two years. Arbitrum and Optimism are among the most established optimistic rollups by total value locked, while Base, launched by Coinbase, and Linea, built by Consensys, represent newer but rapidly scaling deployments. Lido's presence on all four networks positions its staking products as default infrastructure across effectively the entire major optimistic-rollup segment.

Why distribution on L2s matters

Liquid staking is a scale business. Growth now depends less on mainnet deposits, where the market is largely saturated, and more on reaching users where they already transact. L2 networks process the majority of Ethereum transactions at a fraction of mainnet gas costs, making them the natural acquisition channel for staking products. A one-transaction flow on each network lowers the barrier far enough that staking becomes an incidental action rather than a planned cross-chain operation.

For competing liquid staking protocols, the move raises the distribution bar. Protocols without equivalent L2-native flows now face a starker trade-off for users: accept multi-step bridging or accept a smaller staking provider.

What comes next

The rollout is live now on all four networks. The open question for practitioners is integration depth: how quickly wallets and DeFi protocols on Arbitrum, Base, Linea and Optimism adopt the one-transaction flow as a default staking entry point will determine whether this becomes standard infrastructure or simply another option in the market.
