Wu Shuo learned that the Ethereum Foundation announced that the first short-term Pectra fork testnet, Mekong, is now online, which includes all EIP proposals that will soon be applied to the Pectra upgrade, including EIP-7702 to enhance user experience, EIP-7251 to modify staking rules, and EIP-6110 and EIP-7002 to change the deposit and withdrawal mechanisms. This testnet will run for a short term, does not affect the existing network, but the test results will provide a reference for the final deployment of Pectra on Sepolia, Holesky, and the Ethereum mainnet.
