We’re excited to see Gnosis Chain preparing to become a rollup in the Ethereum Economic Zone. It’s a big step for the Gnosis team and for Ethereum!
The transition will introduce protocol changes that are incompatible with the current Shutter encrypted mempool implementation on Gnosis Chain. We will therefore decommission this deployment on Wednesday, 25 November 2026.
Gnosis Chain was the first mainnet to run a Shutter encrypted mempool. It has operated in production for over two years, demonstrating the design on a live network and providing practical experience for our work on Ethereum.
Thank you to the Gnosis team, Nethermind, Erigon, the Keypers, and the validators who ran a Shutterized client and made this work possible.
What this means for you
If you use the Shutter RPC endpoint (erpc.gnosis.shutter.network) in your wallet, switch to a standard Gnosis Chain RPC before 25 November. You can find alternatives on the Gnosis Chain website. After that date, transactions sent through the Shutter endpoint will no longer be processed.
If you run a validator with Shutter enabled, please disable it via the corresponding configuration setting. There is no action needed beyond that.
What’s next
We’re building on our experience on Gnosis Chain as we work on an EIP to bring encrypted transactions to Ethereum mainnet, together with 26 other members of the Encrypt the Mempool coalition.
That work continues with a new draft EIP. It builds on LUCID, the proposed encrypted mempool design for Ethereum, and proposes a solution to the optionality problem. Read the draft and share your feedback on Ethereum Magicians.
