According to Golden Finance, the Ethereum Foundation published an article in its official blog that the Mekong development network was originally intended to provide wallet developers with a place to experiment with user experience (UX) changes, and also allows stakeholders to be confident about future changes in Pectra. The Pectra network upgrade has been activated on Ethereum's Sepolia and Holesky test networks. These networks can now be used to test the functionality of Pectra upgrades. In view of this, the Mekong test network will be discontinued on March 7, 2025.
