1. Unfinished zkSync withdrawal

   zkSync Era

   $113 · 1 position

   You started a withdrawal from zkSync Era (or a similar ZK Stack chain) to Ethereum, but never finalized it on Ethereum. The money sits in the L1 bridge.

   1. Open the ZKsync bridge and connect your wallet.
   2. Find the withdrawal that is ready to finalize. Withdrawals are delayed about 3 hours after they are sent.
   3. Press Finalize and pay the Ethereum gas fee. The funds go to the receiver address.

2. Funds on shut-down Swellchain

   Swellchain, Swell

   $11 · 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. Expired veCRV lock

   Curve

   $10 · 1 position

   Your veCRV lock ended but the CRV was never withdrawn. It is still locked in the contract until you call withdraw.

   1. Open the veCRV VotingEscrow contract on Etherscan, Write Contract.
   2. Connect the owner wallet and call withdraw().
   3. If the owner is a smart contract that cannot make this call, the CRV stays locked.

4. Harmony balance (chain halted)

   $4 · 5 positionsNeeds the team

   Harmony proposed (non-binding, 7 Sept 2026) a final snapshot and an ERC-20 ONE airdrop on Ethereum. This list shows positions at the last block our data saw. You cannot sign anything on the chain now.

   1. Do not expect to withdraw this yourself. The chain is halted.
   2. Watch Harmony's official channels for the vote result and the snapshot rules.
   3. Keep access to your wallet. The proposal says the airdrop would go to the same address on Ethereum.

5. K2 (Karak) chain balance

   $2 · 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.

6. Curve fees not claimed (3CRV)

   $1 · 1 position

   You locked CRV in veCRV and earned fee rewards in 3CRV from the old Curve fee distributor, but never claimed them. They are still in the contract.

   1. Open the contract's Write tab on the block explorer and connect your wallet.
   2. Call claim with your address. Anyone can call it; the tokens go to you.
   3. If many weeks are unclaimed, repeat the call; each call covers up to 20 weeks.
   4. Check your wallet for the 3CRV.

7. 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.

8. Funds in frozen StarkEx apps

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

   $0 · 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.
