Deposited ETH is bridged to Ethereum mainnet, where Lido stakes it and mints staked ETH, known as stETH. That stETH is then wrapped into wstETH and routed back to the Layer 2 to refill the local pool.

Around mid-2025, Lido also worked with partners including XSwap to offer direct staking on Arbitrum, Base, and Optimism in phased rollouts. The October 2026 launch pulls that ...
