In alignment with the upcoming Ethereum Pectra network upgrade, we would like to inform you that Tatum has already deployed all necessary updates to our Ethereum Mainnet infrastructure.

• No downtime is expected on our side during the upgrade window.
• All Ethereum Mainnet services will remain fully operational.
• Please note that while some issues were observed on public testnets during the Pectra rollout, these were related to the broader Ethereum network and are outside of Tatum's control.

For more information about the upgrade, refer to the official Ethereum blog:
