Last update: Aug 15th, 2025
This existing ETH+ vault will transition to an UPGRADED ETH+ Alpha vault on August 20th + up to 48hrs for last NAV update. Users of the existing vault have until August 11th to submit a withdrawal request. The vault will no longer take deposits after the 11th. If no submission is made, funds will automatically transition to the upgraded ETH+ Alpha vault, which is denominated in wETH. If you transition, you receive shares at parity with prior investment in ETH+. This move is to improve potential returns for users.
Users can ALSO wait to withdraw after the transition, receiving equivalent amount of wETH instead of brtkETH when claimable. BrktETH will continue functioning normally as an aggregate token for LST rewards but NO LONGER serve as the denominated asset of the new ETH+ strategy.
👉 ETH+ DeFi Yield vault will no longer accept deposits on Aug 11th
👉 Withdraws before Aug 11th: you’ll get back your brktETH > LSTs
👉 Final withdrawals will be processed on the last NAV lock, August 18th + 48hrs. The vault page will remain up so that any withdraw claims can be made after closure.
👉 If you remain in the vault through the last NAV lock: you’ll be transtioned to ETH+ Alpha - if you'd like, you can submit a withdrawal from the upgraded vault after it starts, >August 21st 2pm EDT.
