Ethereum fixes Glamsterdam bug that could have sent staking deposits to builders

Ethereum developers patched a potential flaw in the planned Glamsterdam upgrade that could have misdirected validator deposits to a builder when they shared a public key. No losses were reported, and client teams still need to incorporate the revised deposit rules.

• The flaw involved pending deposits under a shared public key potentially being credited to a builder rather than a new validator, leaving staking services unable to recover funds.· 1 source
• The proposed fix was closed on October 19, reopened after further review and merged on Monday; the revised rules sort deposits by withdrawal credentials.· 1 source
• No losses were reported, and client teams must implement the changes; Glamsterdam’s October 26 Hoodi test-network launch was postponed.· 1 source
