2. Archived L2 bridge funds

   Archived L2s

   $86 · 3 positionsMay 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.

3. Balancer v2 pool share

   $28 · 3 positions

   You hold Balancer v2 pool tokens, in your wallet or staked. You can exit the pool. Balancer has proposed a wind-down: if it passes, pools become withdraw-only on 30 Oct 2026.

   1. Open the Balancer app, find your pool and use Remove liquidity. Do this before 30 Oct 2026.
   2. If the app does not work, call exitPool on the Balancer v2 Vault 0xBA12222222228d8Ba445958a75a0704d566BF2C8 (Etherscan, Write tab).
   3. If your tokens are staked in Aura, Beefy or a gauge, unstake there first.

6. K2 (Karak) chain balance

   $3 · 1 positionNeeds the team

   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.

    <$1 · 1 position

    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.

13. zkSync Lite balance not claimed

    <$1 · 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.

14. Polygon zkEVM balance

    <$1 · 2 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.
