Lido, the dominant liquid staking protocol on Ethereum, has activated the largest upgrade to its core infrastructure since Lido V2. The protocol has begun migrating more than 8 million staked ether—worth roughly $16.5 billion—onto Ethereum’s newer, high-capacity validator design. That stake represents about a fifth of all ETH currently staked on the network.
The migration falls under Curated Module v2 (CMv2), which the Lido DAO ratified on July 23, 2026, after audits and testnet trials. It is the most significant structural update since Lido V2 launched in 2023. The overhaul applies the validator framework introduced in Ethereum’s Pectra upgrade, which raised the maximum effective balance per validator from 32 ETH to 2,048 ETH. Before Pectra, Lido needed a massive fleet of validators to manage its position. Now, those individual 32 ETH nodes can be folded together.
The immediate network effect is a sharp reduction in validator count. Lido expects the consolidation to cut Ethereum’s total validator count by about one-third. Attestation messages—the signals validators broadcast each epoch to confirm the state of the chain—are projected to drop by roughly 29% per epoch. This eases the load on the consensus layer, though it will not directly reduce gas fees or speed up transactions for end users.
