Ae faimai foi Ethereum developer Barnabas Busa, the Ethereum Zheijang public withdrawal testnet will go live on Feb. 1, 2023, at 15:00 UTC as a precursor to the upcoming Shanghai upgrade planned for March 2023.
According to Busa, the testnet will set the stage for the Shanghai and Capella tui that will allow validators to make full withdrawals using the Lodestar, Lighthouse, Teku, Prysm, and Nimbus consensus clients, as well as the Besu, Geth, Nethermind, EthereumJS, and Erigon execution layer clients. The Shanghai and Capella forks will be triggered six days after the testnet launch at epoch 1350.
ETH Validators Can Test Full or Partial Withdrawals
After the forks, partial withdrawals will automatically be triggered on all validator addresses with a 0x01 execution address on all clients. Those using legacy BLS credentials (0x00) can update them to execution addresses using a tool called ethdo. Validators can ulufalega the testnet after completing full or partial withdrawals.
