Lido, the largest liquid staking protocol on Ethereum, said this week that 40% of its staked ETH is now running on 0x02 validators. The 0x02 credential type is the newer standard that lets validators hold more than the original 32 ETH maximum and manage withdrawals differently than the older 0x00 and 0x01 formats. Lido's disclosure puts a concrete number on a migration that has been ticking along in the background of Ethereum staking for months.
What 0x02 actually changes under the hood
Ethereum validators have long been identified by their withdrawal credentials. The original 0x00 format couldn't trigger withdrawals at all. The 0x01 format, introduced around the Merge and Shanghai upgrade, tied a validator to an execution-layer address so it could exit and pull its balance. The 0x02 format goes further: it allows a validator to carry an effective balance above 32 ETH, which means rewards can compound in place instead of being swept out.
For a staking provider like Lido, that matters because it shrinks the operational overhead that comes with every chunk of ETH it stakes. Fewer validators moving through the queue, fewer withdrawal sweeps to manage, and a cleaner path toward compounding. Lido's note says the shift could streamline the network and potentially increase staking rewards. The word "potentially" is doing real work there — reward outcomes depend on how much of the rest of the validator set follows.
Why Lido is moving first among the big stakers
Lido's size is the reason. When you run a meaningful share of all staked ETH, small efficiency gains compound into real operational savings, and small frictions compound into real headaches. Every 0x01 validator that maxes out at 32 ETH is another validator Lido has to spin up, provision, and eventually exit. Consolidating into 0x02 validators lets the protocol do more with fewer validator slots.
There's also a network-level argument. Ethereum's validator set has swelled into the hundreds of thousands, and a chunk of the community has grumbled for a while about the resulting gossip and consensus overhead. If large operators consolidate onto 0x02 credentials, the total validator count can come down without touching the amount of ETH securing the chain. Lido putting a hard 40% figure on its own migration is one of the clearest signals yet that the big staking pools are taking that seriously.
The part that isn't settled yet
Lido hasn't said when it expects to finish the migration, and it hasn't quantified the reward improvement it's targeting. That's the number everyone will actually want. Compounding rewards sound good in a sentence, but the delta between a swept 0x01 validator and a compounding 0x02 one depends on execution-layer fees, MEV flows, and how the protocol passes rewards through to stETH holders. None of that was in the disclosure.
There's a competitive angle too. Other large staking operators still run heavily on 0x01 credentials. If 0x02 consolidation produces a measurable yield edge for Lido, expect the rest of the field to follow quickly — and expect the pitchforks over staking centralization to come back out, because fewer, larger validators is exactly the shape some critics have warned about. Lido hasn't addressed that criticism in this update. It probably won't have to until the rest of the pack starts converting.
For now the next concrete checkpoint is Lido's own progression past 40%. The protocol hasn't published a target date, so watch for the figure to move in future updates — or for a competitor to announce a 0x02 push of its own.
