1. K2 (Karak) chain balance

   $2,948 · 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.

2. Funds in old Ethereum contracts (2015-2021)

   $268 · 4 positions

   You have a balance in an old Ethereum contract (The DAO, EtherDelta, IDEX, the 2017 ENS registrar, DigixDAO and others). Each contract has its own withdraw call. Use the wallet that owns the position.

   1. The DAO: on the DAO token 0xbb9bc244d798123fde783fcc1c72d3bb8c189413 call approve(0xbf4ed7b27f1d666546e30d74d50d173d20bca754, yourBalance). Then call withdraw() on the WithdrawDAO contract 0xbf4ed7b27f1d666546e30d74d50d173d20bca754. It pays 1 ETH per 100 DAO.
   2. EtherDelta 0x8d12a197cb00d4747a1fe03395095ce2a5cc6819: from the wallet that deposited, call withdraw(amount) for ETH or withdrawToken(token, amount) for a token. Amounts are in the token's smallest unit.
   3. IDEX v1 0x2a0c0dbecc7e4d658f48e01e3fa353f44050c208: call withdraw(token, amount). Use token 0x0000000000000000000000000000000000000000 for ETH. It reverts if your last IDEX activity was fewer than 240 blocks ago.
   4. 2017 ENS registrar 0x6090a6e47849629b7245dfa1ca21d94cd15878ef: call releaseDeed(labelhash) for the name. The labelhash is keccak256 of the name without .eth. The deposit goes back to the deed owner.
   5. Other contracts (DigixDAO, Neufund and more): use the contract's own withdraw or refund function on Etherscan from the owner wallet. Check the contract's code first.

   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.

   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.

10. zkSync Lite balance not claimed

    <$1 · 2 positions

    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.

    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.

    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.

13. Ended Sablier stream (no price)

    $0 · 2 positions

    An ended or canceled Sablier stream whose token has no known price. Most are airdrop vesting or spam tokens, so the value is unknown and may be zero.

    1. Open the Sablier app and connect the wallet that owns the stream.
    2. Press Withdraw on the ended stream if you want the tokens.
    3. Be careful with unknown tokens: many are spam.

14. Harmony balance (chain halted)

    $0 · 1 positionNeeds 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.
