Ethereum has launched the “short-lived” Mekong testnet to test key upgrades for the upcoming Pectra fork.

The Ethereum ecosystem is taking another step toward the Pectra fork with the launch of the Mekong testnet, a short-lived environment designed to test key updates ahead of the mainnet upgrade.

The testnet integrates a range of Ethereum Improvement Proposals, including user experience adjustments, staking modifications, and changes to the deposit and exit mechanisms, the Ethereum Foundation explained in a Nov. 7 blog post.

“We may see some minor spec changes or smaller EIPs, but the features included here will make it into existing public testnets and finally Ethereum mainnet.”

Per the blog announcement, the testnet, which will run for a limited time, is feature complete with all the major updates slated for inclusion in Pectra. It is unclear though for how long the testnet will go live. While minor adjustments may still occur, the core changes will make their way to Ethereum’s public testnets and, eventually, the mainnet, the foundation says.

Those interested in participating in the testnet can access the Mekong network via its landing page, where they can connect their wallets, explore block data, and request test funds. Instructions for running a node on the testnet are also available, with participants required to operate both an Execution and Consensus layer node, as they would on Ethereum’s mainnet.

The foundation also noted that the Mekong testnet will not affect other Ethereum networks, like Holesky or Sepolia, but the insights gained from testing will inform the broader implementation of Pectra. It is assumed that the upgrade will go live in Q1 2025.
