Ethereum patch prevents staked ETH misallocation
6.7 Tech Ethereum devs fixed a Glamsterdam upgrade flaw that could have sent validator deposits to block builders. The correction separates builder and validator deposits, preventing ETH misallocation. No losses occurred.
Ethereum developers have resolved a critical vulnerability in the upcoming Glamsterdam upgrade. The flaw, discovered in October, could have allowed block builders to receive ETH meant for new validators if both shared the same public key. This issue was linked to the enshrined proposer-builder separation (ePBS) mechanism, which divides block proposal and construction roles. Initially, the proposed fix was rejected, but after further testing, it was accepted and merged into the consensus specifications on October 26. The update ensures builder and validator deposits are separated based on withdrawal credentials, preventing misallocation of funds. No losses have been reported. Client teams are now required to implement and test the revised rules before the Glamsterdam upgrade can launch on mainnet. The fix only impacts deposits queued at the fork, and a separate contract compatibility review has delayed the Hoodi activation within the upgrade.
