Gnosis Chain Chiado - Pectra Hardfork

Action Required: Update Your Nodes NOW!

Attention Chiado Validators,

The Gnosis Chain Chiado testnet is scheduled for a hard fork on March 6, 2025, at 09:43:40 UTC (Slot 15171584, timestamp 1741254220). This upgrade, known as Pectra, brings significant improvements and requires immediate action from all Chiado node runners.

To ensure uninterrupted participation and fully benefit from the Pectra upgrade, please update your nodes to the compatible client versions listed below before the hard fork.

Execution Layer Clients:

• Nethermind: Upgrade to version v1.31.3 (Docker image: nethermind/nethermind:1.31.3)

• Erigon: Upgrade to version v2.61.2 (Docker image: erigontech/erigon:v2.61.2) or v3.0.0-rc1 (Docker image: erigontech/erigon:v3.0.0-rc1)

Consensus Layer Clients:

• Lighthouse: Upgrade to version v7.0.0-beta.0 (Docker image: sigp/lighthouse:v7.0.0-beta.0)

  • Important: Requires a custom configuration. Download https://github.com/gnosischain/configs/tree/main/chiado, remove the `--network` flag and add `--testnet-dir="/chiado"` to both the beacon client and validator.

• Lodestar: Upgrade to version v1.27.1 (Docker image: chainsafe/lodestar:v1.27.1)

• Nimbus: Upgrade to version v25.3.0 (Docker image: ghcr.io/gnosischain/gnosis-nimbus-eth2:v25.3.0)

• Teku: Upgrade to version v25.2.0 (Docker image: consensys/teku:25.2.0)

  • Requires a custom configuration.

    curl https://raw.githubusercontent.com/gnosischain/specs/refs/heads/master/consensus/preset/gnosis/electra.yaml >> configs/chiado/config.yaml
    

    2. Add the following flags to Teku:

    --network="/configs/chiado/config.yaml"
    --genesis-state="/configs/chiado/genesis.ssz"
