1. K2 (Karak) chain balance

   $184 · 2 positionsNeeds 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.

2. Unclaimed Arbitrum withdrawal

   Arbitrum One, Arbitrum Nova

   $141 · 1 position

   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.

3. Polygon zkEVM balance

   $23 · 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.

4. Funds in frozen StarkEx apps

   Sorare, Immutable X, ApeX Pro, edgeX v1, Myria

   $5 · 1 positionMay not work

   Some StarkEx apps keep balances off-chain. A pending withdrawal can be claimed now. A deposit-only record cannot: the app operator must first publish data.

   1. Check the row type. A pending withdrawal can be claimed now; a deposit ledger row cannot.
   2. For a pending withdrawal, call withdraw with your owner key and asset type on the app's StarkEx contract (Etherscan). Funds go to your registered address.
   3. For a frozen app, the escape hatch needs the operator or data committee to publish state first. See the StarkWare docs.

5. Archived L2 bridge funds

   Archived L2s

   $2 · 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.

6. zkSync Lite balance not claimed

   <$1 · 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.

7. Orbit Lending deposit on Blast

   <$1 · 2 positions

   You supplied funds to Orbit Lending on Blast, which was exploited. You can still withdraw, but some markets hold less cash than is owed, so first come, first served.

   1. Open your cToken contract (listed in the row) on Blast's block explorer, Write tab, connect wallet.
   2. Call redeem(cTokenBalance) or redeemUnderlying(amount).
   3. If you have a borrow in the same market, repay it first; your collateral is locked until then.
