1. MKR never converted to SKY

   Maker / Sky

   $9,360 · 1 positionMay not work

   You hold MKR, or MKR in the old DSChief voting contract, that was never converted to SKY. The converter still works. Its fee is 5% now (read on-chain 2026-10-01) and rises 1 point every 3 months.

   1. Open the Sky app and connect your wallet.
   2. If your MKR is in the old DSChief voting contract, first call free(amount) on that contract.
   3. Approve MKR, then convert it to SKY. You get 24,000 SKY per MKR minus the fee.
   4. Without the app: call mkrToSky(usr, mkrAmt) on the converter 0xA1Ea1bA18E88C381C724a75F23a130420C403f9a.

2. Unclaimed Agglayer bridge exit

   Polygon Agglayer (Silicon, Katana, X Layer and others)

   $1,645 · 1 position

   You sent funds from an Agglayer chain to Ethereum but never claimed them on Ethereum. The funds wait in the Ethereum bridge contract.

   1. Use the official bridge of the chain you withdrew from (linked next to each of your positions).
   2. Connect the receiving wallet and open your transaction history.
   3. Find the withdrawal marked ready to claim and press Claim. You pay the Ethereum gas fee.

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

   $1,481 · 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.

4. Old SAI stablecoin to cash out

   Maker SAI

   $974 · 1 positionMay not work

   SAI (the first Dai) was shut down. Each SAI can still be cashed for a fixed amount of WETH: 0.0052856 WETH per SAI (read from the contract).

   1. Approve first: on the SAI token 0x89d24A6b4CcB1B6fAA2625fE562bDD9a23260359 call approve(spender = 0xBda109309f9FafA6Dd6A9CB9f1Df4085B27Ee8eF, amount).
   2. Open the SaiTap contract 0xBda109309f9FafA6Dd6A9CB9f1Df4085B27Ee8eF on Etherscan, Write tab, and connect your wallet.
   3. Call cash(wad) with your SAI amount. You receive WETH.

5. Hop transfer not received

   Hop Protocol

   $539 · 1 position

   You sent a Hop transfer long ago and it was never paid out on the destination chain. The funds are still in Hop's bridge contract and its withdraw function still works, but Hop's website and data service are gone, so there is no ready tool: the withdrawal has to be built from on-chain data.

   1. hop.exchange and every address under it (app.hop.exchange, docs.hop.exchange) no longer belong to Hop: hop.exchange now shows a gambling site. Do not open them or connect a wallet there.
   2. Find your transfer in the TransferSent event of your transaction on the origin chain (block explorer, Logs tab). It holds the transfer ID, recipient, amount, transferNonce, bonderFee and the swap values.
   3. The withdraw function also needs a Merkle proof of your transfer. Hop's open-source node tool has a withdrawal-proof command for it, but the tool reads Hop's data service at subgraph.hop.exchange, which no longer answers, so a developer has to point it at another source or rebuild the proof from on-chain events.
   4. With the proof, call withdraw on the Hop bridge contract of the destination chain (block explorer, Write tab) from the wallet that should receive the funds. You pay gas.
   5. On a Layer 2 destination you receive hTokens (for example hUSDC). They can be swapped to the native token in Hop's AMM on that chain.

6. zkSync Lite balance not claimed

   $192 · 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. AutoFarm staked deposit

   $144 · 1 position

   You staked in an AutoFarm pool. The website is gone, but the farm contract is still live and holds your deposit.

   1. Open the AutoFarmV2 chef contract (chef column) on the block explorer, Write Contract.
   2. Connect your wallet and call withdraw(pid, amount).
   3. Works on BNB Chain, Polygon, Avalanche and Cronos.

8. Funds on shut-down Swellchain

   Swellchain, Swell

   $5 · 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.

9. Polygon zkEVM balance

   <$1 · 1 position

   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.

10. Nucleus vault shares

    Nucleus (BoringVault)

    <$1 · 1 position

    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.
