Lido's 0x02 CSM testnet is now live, with a mainnet launch planned for October 2026. The new module allows up to 2,048 ETH per validator, a 64x jump from the current 32 ETH cap. ETH update: this change aims to simplify operations for large stakers while keeping the system open. Built on CSM v3, it will run alongside the 0x01 module. ETH news: the upgrade supports compounding rewards without breaking compatibility.

Lido’s next-generation Community Staking Module just hit testnet, and the numbers tell a story about where Ethereum staking is headed. The 0x02 CSM, now live at csm.testnet.fi, allows validators to operate with withdrawal credentials supporting compounding balances of up to 2,048 ETH per validator. That’s 64 times the current 32 ETH cap under the existing 0x01 framework.

Mainnet deployment is targeted for October 2026, following approval by the Lido DAO. If that timeline holds, it would represent one of the most significant upgrades to Ethereum’s staking infrastructure since Lido launched its original CSM in 2024.

What the 0x02 upgrade actually changes

The existing 0x01 CSM limits each validator to a maximum effective balance of 32 ETH. That means if you want to stake more, you need to spin up additional validators, each requiring its own bond and operational overhead.

The 0x02 module flips that model. A single validator can now compound rewards up to 2,048 ETH, dramatically reducing the operational complexity for larger stakers while maintaining the permissionless ethos that made the original CSM appealing to solo operators.

The deposit process is split into two phases. Validators start with an initial 32 ETH deposit, then layer on additional top-ups over time.

Bond parameters proposed for the module call for 32 ETH on the first key and 30 ETH for subsequent keys, paired with an 8% DAO rewards allocation. The capital efficiency gains are substantial: Lido estimates that fully topped-up validators could see roughly a 2.26x efficiency multiplier compared to traditional solo staking.

Why Lido split the modules

Supporting both 0x01 and 0x02 withdrawal credential types within a single module creates hybrid compatibility issues. Different credential types have different operational mechanics, bond caps, and compounding behaviors. By separating them, Lido can tailor bond parameters and operational rules to the specific needs of each validator type. The 0x01 module continues to serve validators who prefer the simplicity of the 32 ETH model. The 0x02 module caters to those who want to consolidate capital and reduce validator sprawl.

The new module is built on version 3 (v3) of the existing CSM architecture.

Market implications and Lido’s positioning

The permissionless design maintains open entry without KYC requirements or minimum capital thresholds beyond the initial 32 ETH deposit, with validators able to scale toward the 2,048 ETH ceiling.

That combination of capital efficiency and open access could pull validators away from competing staking providers. If you can achieve 2.26x the capital efficiency of solo staking through a permissionless module, the economic incentive to migrate is straightforward math rather than brand loyalty.
