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. Cat in a Box stETH deposit

   <$1 · 1 position

   Cat in a Box was a loan system backed by stETH. catinabox.finance still loads but shows no data, and the contract still works, so you can try to take out your stETH deposit.

   1. Open the contract from your row's 'contract' column in the explorer, Write tab, and connect your wallet.
   2. If your row shows debt, repay the synthetic token first, or withdraw only up to the loan limit.
   3. Call withdraw(amount). Pay the fee in ETH.

3. Polygon zkEVM balance

   <$1 · 3 positions

   Polygon zkEVM's sequencer stopped on 1 July 2026. Wallet-held funds not bridged before then can be claimed on Ethereum in a claim UI. Polygon treats unclaimed assets as abandoned after 2027-12-31.

   1. Open the Polygon zkEVM claims site and connect the wallet that held the funds.
   2. Pick your balances and send the claim transaction on Ethereum.
   3. Funds locked inside DeFi contracts are not auto-migrated. Ask Polygon through the forum post.
