1. zkSync Lite balance not claimed

   $3 · 1 position

   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.

2. Funds on shut-down Swellchain

   <$1 · 1 position

   Swell closed Swellchain: the final withdrawal deadline was 2026-06-15 and the chain was to run until 2026-06-30. Withdrawals started before 15 June can still be finalized on Ethereum.

   1. If your withdrawal was started before 15 June: after the 7-day proof wait, prove it on the Ethereum OptimismPortal2 0x758E0EE66102816F5C3Ec9ECc1188860fbb87812 (proveWithdrawalTransaction).
   2. Then call finalizeWithdrawalTransaction on the same contract. You pay ETH gas.
   3. If you never started one: Swell said contract withdrawals were possible until 30 June but are technical. Ask Swell support.

3. Across deposit never filled

   $0 · 5 positionsMay not work

   You sent a deposit through Across but nobody filled it on the other chain. Expired deposits are refunded by Across in batches. If no refund arrived long after expiry, contact Across support.

   1. Find your deposit transaction hash on the origin chain explorer.
   2. Look up the hash in the Across Deposit Status Tracker (linked in the Across docs). Status 'expired' means the refund is queued.
   3. Refunds go through batches that take several hours. If nothing arrives long after expiry, send the hash to Across support.
   4. No refund address was set? The refund goes to the depositor address.
