A contract interaction needs more testing
ChainSecurity published an analysis on October 13 describing a possible interaction between EIP-8038 and existing failure-handling logic. Under some conditions, a failed call could leave enough gas for a failure handler to execute unexpectedly. In other cases, a previously valid operation could fail because the gas accounting changed.
The concern does not mean that Ethereum mainnet has already been affected. Developers delayed Hoodi so the behaviour can be tested before the same changes move further through the release process.
Sepolia activated earlier, but Hoodi now needs a new schedule
Glamsterdam activated successfully on the Sepolia testnet on October 6. Hoodi had been configured for epoch 132352, slot 4235264, at 17:42:48 UTC on October 26. Those numbers are now historical and must not be treated as the current schedule.
The wider Glamsterdam package includes enshrined proposer-builder separation and block access lists. Those features continue to be developed. The delay gives client and application teams more time to test their interaction instead of locking in a date before the open issue is resolved.
| Network or component | Status |
|---|---|
| Sepolia | Activated on October 6, 2026 |
| Hoodi | October 26 activation postponed; no new date |
| Old Hoodi coordinates | Epoch 132352, slot 4235264 |
| Gas limit | 200 million change removed from the delayed activation |
| Mainnet | No activation date announced |
Node operators should follow releases from each client team
Updated releases include Lodestar 1.50.1, Besu 26.10.1, the Ethrex 30.0.1-rc.2 prerelease and Nethermind 2.2.1. Releases come from the individual client teams; they should not be described as software issued by the Ethereum Foundation.
Operators using Grandine, Lighthouse, Nimbus, Prysm, Teku, Erigon, Geth or Reth should wait for confirmation from the relevant project. Mainnet users do not need to move funds or change wallets. The practical task belongs to Hoodi node operators and developers testing the upgrade.
