# Description Adds support for the upcoming Ethereum Electra upgrade, while maintaining backwards compatibility for the current Deneb fork. ## Integration Relayers should be updated to send updated Electra consensus data structures. ## Review Notes The [Ethereum Electra hard-fork consensus](https://github.com/ethereum/consensus-specs/blob/dev/specs/electra/light-client/sync-protocol.md) changes affecting the Ethereum light client are mainly isolated to the [Generalized Indexes](https://github.com/protolambda/eth2.0-ssz/blob/master/specs/navigation/generalized_indices.md) of data structures changing. Before Electra, these values were hardcoded in config. For Electra, these values change and needed to the updated. Methods were added to return the correct g-index for the current fork version. Data structures used by the Ethereum client did not change in this hard-fork. The BeaconState container has been updated with additional changes, but because the on-chain code does not reference the BeaconState directly (only indirectly through merkle proofs), it is not a concern. Off-chain relayers use the BeaconState to generate proofs, and so the relayer code has been updated accordingly. ### Companion PR for off-chain relayers Snowfork/snowbridge#1283 --------- Co-authored-by: claravanstaden <Cats 4 life!> Co-authored-by: Ron <[email protected]> Co-authored-by: Vincent Geddes <[email protected]> Co-authored-by: Alistair Singh <[email protected]> Co-authored-by: Vincent Geddes <[email protected]> (cherry picked from commit dd7562a)
