The Ethereum Foundation has announced a short-lived testnet called Mekong. This testnet provides developers with the opportunity to try out upcoming upgrades before they hit the Ethereum mainnet. Mekong provides a space for wallet developers to test UX changes and for stakers to gain confidence in upcoming changes. The foundation noted that Mekong includes all EIPs for the Pectra hard fork and will not impact mainnet. Developers are welcome to provide feedback, focusing on UX changes. Share your thoughts in the comments.
