1. zkSync Lite balance not claimed

   $133 · 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.

2. Nucleus vault shares

   Nucleus (BoringVault)

   $37 · 3 positions

   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.

3. K2 (Karak) chain balance

   $13 · 1 positionNeeds the team

   The K2 team's bridge on Ethereum now pays balances by Merkle proof (a list that proves your balance). The merkle root is set and claims are not paused. After 2027-09-12 the guardian can sweep what is left.

   1. Ask the K2 team for your Merkle proof. We could not find an official page that gives proofs.
   2. On the OptimismPortal 0xeeCE9CD7Abd1CC84d9dfc7493e7e68079E47eA73 call claimETH(_amount, _proof) for ETH.
   3. For tokens, call claimTokens(_tokens, _amounts, _proof) on the L1StandardBridge 0xBA61F25dd9f2d5f02D01B1C2c1c5F0B14c4B48A3.

4. Archived L2 bridge funds

   Archived L2s

   <$1 · 1 positionMay not work

   This chain shut down and its state is gone, so no one can prove a withdrawal now. The Ethereum bridge still holds the money; only the chain team can release it.

   1. Use the official bridge of the chain you withdrew from (linked next to each of your positions).
   2. Check that chain's official site for a refund or recovery notice.
   3. Without the chain's final state nobody can prove a withdrawal. Only the chain team can release the bridge funds.

5. Across deposit never filled

   $0 · 3 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.

   1. Open cBridge and connect the wallet that sent the transfer.
   2. Open transfer history and find the transfer marked as refundable.
   3. Press Request Refund and confirm. You pay the gas fee on the source chain.
