1. dYdX v3 balance

   $500 · 1 position

   dYdX v3 was shut down and its exchange was set to 'frozen' on Ethereum. Your USDC can still be taken out through the escape hatch, or withdrawn if already released.

   1. Open dYdX's v3 sunset post and use the Escape Hatch link in its last update. It is hosted by an independent third party.
   2. Escape needs a proof for your stark key and position. The page builds it; the escape call goes to StarkPerpetual 0xD54f502e184B6B739d7D27a6410a67dc462D69c8.
   3. Then call withdraw from your registered Ethereum address to receive the USDC. You pay Ethereum gas.

2. zkSync Lite balance not claimed

   $72 · 2 positions

   zkSync Lite was shut down on 2026-05-04. Remaining balances are claimable on Ethereum through a claim contract and a withdrawal portal. Your account is on that list and has not claimed.

   1. Open the zkSync Lite withdrawal portal and connect the wallet that owned the account.
   2. The portal finds your address in the final state, builds the proof and sends the claim. Follow its prompts.
   3. Confirm the Ethereum transaction. Tokens go to your L1 address. Matter Labs sponsors gas for the first 100,000 withdrawals.
