1. zkSync Lite balance not claimed

   $9 · 4 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.

2. ReactorFusion deposit (zkSync)

   ReactorFusion (zkSync)

   $8 · 1 position

   ReactorFusion lending is shut down and the website is gone. Your deposit receipt token may still be redeemable, but only for the cash left in the market, after you repay any debt.

   1. Open the receipt token contract of your market (in your row) in the block explorer, Write tab, and connect your wallet.
   2. If you have an open loan, repay it first.
   3. Call redeem or redeemUnderlying (or withdraw, if the contract shows that name). You get at most the cash still in the market.
   4. Not tested by us. Pay the network fee in the chain's coin. A developer may be needed.

3. Unclaimed OP Stack chain withdrawal

   Blast, Mantle, Mode, Zora, Lisk, Ink, Unichain and other OP chains

   $3 · 1 position

   You withdrew from an OP Stack chain to Ethereum but never completed the last step. The funds wait in that chain's bridge.

   1. Use the official bridge of the chain you withdrew from (linked next to each of your positions).
   2. Connect the receiving wallet and open your transactions. Press Prove, wait out the challenge period shown on the page, then press Finalize.
   3. Pay the Ethereum gas fee each time.

4. Nucleus vault shares

   Nucleus (BoringVault)

   <$1 · 1 position

   Nucleus deprecated its vaults on 19 Dec 2025 and the withdraw page is gone. You can redeem vault shares through the Teller contract, but only for assets the vault still holds.

   1. Read the Nucleus deprecation guide first.
   2. Check which tokens the vault still holds, and your vault token balance, on Etherscan (or the Plume explorer).
   3. On the vault's Teller contract, Write tab, call bulkWithdraw(withdrawAsset, shareAmount, minimumAssets, to). The guide says to use 0 for minimumAssets.

5. Unclaimed Arbitrum withdrawal

   Arbitrum One, Arbitrum Nova

   <$1 · 2 positions

   You withdrew ETH or tokens from Arbitrum to Ethereum but never did the final claim on Ethereum. The challenge period (about 6.4 days) is long over, so the funds can be claimed now.

   1. Open the Arbitrum bridge and connect the receiving wallet.
   2. Open Transactions and find the withdrawal marked Claim, or paste the withdrawal transaction hash.
   3. Press Claim and confirm. You pay the Ethereum gas fee. The funds go to the recipient.
