• Mekong testnet allows developers to test UX and staking updates ahead of the Pectra upgrade.
• Stakers can experiment with new deposit and withdrawal workflows.

The Ethereum Foundation has launched the Mekong testnet, a crucial step towards the upcoming Pectra upgrade. The testnet, which is a short-term environment, is designed to allow developers to explore user experience (UX) improvements and familiarize themselves with staking changes ahead of the Pectra fork. This development follows an extensive evaluation of the fork’s scope, including a successful interoperability event and four developer networks.


Mekong incorporates all Ethereum Improvement Proposals (EIPs) planned for the Pectra fork. Key updates include EIP-7702, which focuses on enhancing user experience. EIP-7251, which introduces staking changes, and EIP-6110 and EIP-7002, which modify deposit and withdrawal mechanisms. These updates aim to improve the overall functionality of Ethereum and prepare it for smoother integration into the mainnet.

Previewing Ethereum’s Pectra Upgrade

The testnet is an opportunity for wallet developers to experiment with new UX features and for stakers to test the upcoming changes. The Ethereum Foundation has emphasized that while the Mekong is a short-lived testnet. It is feature-complete with all the intended updates. Any minor adjustments or additional EIPs may arise, but the core features will eventually be deployed on existing public testnets and, ultimately, the Ethereum mainnet.

To use the Mekong testnet, developers and users can visit the network’s landing page. From there, they can add the network to their browser wallet, access block explorers, request funds from the faucet, and connect to a JSON RPC endpoint.

Running a node on Mekong requires both an Execution and Consensus layer node, similar to Ethereum’s mainnet. Stakers will also be able to experiment with changes to the staking workflow, particularly regarding deposits and withdrawals.

Moreover, The name “Mekong” was chosen to honor the Mekong River, which flows through Southeast Asia. This symbolic reference connects the testnet to the upcoming Devcon event in Bangkok, further highlighting Ethereum’s global community.

Despite its brief existence, the Mekong testnet is vital for ensuring the successful implementation of Pectra. It will not impact the Ethereum mainnet or other testnets like Holesky or Sepolia but will inform the eventual deployment of the Pectra upgrade across Ethereum’s networks. Developers are encouraged to provide feedback to help refine the features ahead of the mainnet launch.
