On February 14th, according to the official blog of the Ethereum Foundation, the Pectra network upgrade plan has been launched on the Ethereum testnet. It will go live on Holesky at epoch 115968 (February 25th, 05:55 Beijing time), and then on Sepolia at epoch 222464 (March 5th, 15:29 Beijing time). The Pectra testnet client versions are listed below. After the successful upgrade of the two testnets, a mainnet activation epoch will be chosen. Pectra is launched following last year's Dencun upgrade. It introduces enhanced Ethereum accounts, improved validator experience, support for L2 scaling, and more features.
