This new testnet, which will go live at 10 a.m. ET (15:00 UTC), will provide the ability to test staked ETH withdrawals (EIP-4895). Users won’t immediately have the ability to participate in the simulated withdrawals until the testnet goes through an upgrade on Feb. 7. For now, users will be able to deposit ETH to validators on the testnet, and then withdraw them the following week.
