The Ethereum Foundation’s April 2025 Pectra announcement scheduled the upgrade for 7 May 2025. Its account changes centred on EIP-7702, which allows an externally owned account to delegate behaviour to code.
The notice describes possibilities such as batching actions, alternative authentication and recovery mechanisms. It also explains that selecting a delegation target grants substantial control, making that choice an important security consideration.
Pectra’s announcement covers changes to blob capacity and validator operation as well. This archive brief reports what the original upgrade notice contained. It is not a current operational checklist; readers working on today’s network should check subsequent client documentation and protocol changes.
