1. zkSync Lite balance not claimed

   $141 · 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. EigenLayer withdrawal not completed

   $48 · 1 position

   You queued a withdrawal from EigenLayer and the waiting time has passed, but you never completed it. Only the withdrawer address can complete it.

   1. Open the EigenLayer app and connect the withdrawer wallet.
   2. Find your queued withdrawal and press Complete.
   3. Choose to receive the tokens (not re-deposit). Confirm and pay gas in ETH.

3. Polygon zkEVM balance

   $23 · 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.
   3. Funds locked inside DeFi contracts are not auto-migrated. Ask Polygon through the forum post.

4. dYdX v3 balance

   $4 · 1 position

   dYdX v3 was shut down and its exchange was set to 'frozen' on Ethereum. Your USDC can still be taken out through the escape hatch, or withdrawn if already released.

   1. Open dYdX's v3 sunset post and use the Escape Hatch link in its last update. It is hosted by an independent third party.
   2. Escape needs a proof for your stark key and position. The page builds it; the escape call goes to StarkPerpetual 0xD54f502e184B6B739d7D27a6410a67dc462D69c8.
   3. Then call withdraw from your registered Ethereum address to receive the USDC. You pay Ethereum gas.

5. MATIC never swapped to POL

   Polygon

   $3 · 1 position

   You hold old MATIC on Ethereum that was never swapped to POL. The swap is 1 to 1. Polygon has not announced a deadline.

   1. Open the Polygon Portal upgrade page and connect your wallet. Switch the wallet to Ethereum.
   2. Approve the upgrade contract to use your MATIC.
   3. Confirm the migrate transaction to receive POL. You pay Ethereum gas.

6. Funds in frozen StarkEx apps

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

   $2 · 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.

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

   $2 · 3 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.

8. USDC burned but not minted

   Circle CCTP

   $1 · 1 position

   USDC was burned on one chain through Circle CCTP but the matching USDC was never minted on the destination chain. Circle can still sign it, so it can be completed.

   1. Find the burn transaction hash on the source chain.
   2. Get the signed attestation for it from Circle's attestation API (see the Circle CCTP docs).
   3. On the destination chain, call receiveMessage(message, attestation) on the MessageTransmitter contract. You pay the gas fee. USDC goes to the recipient.

9. PieDAO index token

   $1 · 1 position

   PieDAO index tokens (pies) on Ethereum are still backed by a basket of tokens. You can exit the pool and get the underlying tokens.

   1. Open the pie token contract (the 'contract' column) in the explorer, Write tab, and connect your wallet.
   2. Call exitPool(amount) to receive the basket tokens pro rata.
   3. USD++ failed in a test. If your token is in a Balancer or Uniswap pool, remove that liquidity first.

10. KNCL never swapped to KNC

    Kyber (KNCL)

    $1 · 1 positionMay not work

    You hold old KNCL tokens that were never swapped to KNC. The KNC token contract still accepts them.

    1. Approve first: on the old KNC token (KNCL) 0xdd974D5C2e2928deA5F71b9825b8b646686BD200 call approve(spender = 0xdeFA4e8a7bcBA345F687a2f1456F5Edd9CE97202, amount).
    2. Open the KNC contract 0xdeFA4e8a7bcBA345F687a2f1456F5Edd9CE97202 on Etherscan, Write as Proxy tab, and connect your wallet.
    3. Call mintWithOldKnc(amount). It burns your KNCL and mints KNC 1 to 1.

11. KEEP never swapped to T

    Threshold (KEEP)

    <$1 · 1 positionMay not work

    You hold old KEEP tokens that were never wrapped into T. The Threshold VendingMachine still does the swap.

    1. Open the KEEP VendingMachine 0xE47c80e8c23f6B4A1aE41c34837a0599D5D16bb0 on Etherscan, Write tab, and connect your wallet.
    2. First approve: on the KEEP token 0x85eee30c52b0b379b046fb0f85f4f3dc3009afec call approve(spender = the VendingMachine, amount). Amounts use 18 decimals.
    3. Then call wrap(amount) on the VendingMachine to receive T. Threshold says there is no deadline.
