dev.to published a compatibility review of the ether.fi Stake protocol on 4 October 2026. The report covers a TVL of approximately $5.18 billion across Ethereum and L2 networks. ether.fi Stake aggregates deposits and delegates them to the Ethereum consensus layer. The protocol uses a UUPS and Diamond proxy architecture for upgrades.
The review assessed the transition from version v2.3 to v2.4. The overall risk score is 6 out of 10, indicating medium-high risk. Technical feasibility is confirmed, but compatibility gaps remain.
These gaps could allow attackers to exploit the system or cause fund loss. The upgrade path is considered architecturally sound. Recommendations include fixing storage gaps and adding re-entrancy guards. A full rehearsal and third-party audit are advised before the DAO timelock submission.
