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

   $1,025 · 2 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.

   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.

3. dYdX v3 balance

   $472 · 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 Your USDC can still be taken out through the escape hatch, or withdrawn if already released.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.

4. Harmony balance (chain halted)

   $102 · 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. FTM never moved to Sonic (S)

   Fantom to Sonic

   $31 · 1 position

   You hold FTM on Ethereum that was never moved to S on Sonic. Sonic's guide says the Sonic Gateway bridges it 1 to 1.

   1. Open the Sonic Gateway and connect the wallet that holds FTM on Ethereum.
   2. Select FTM (Ethereum), enter the amount, click Bridge and approve the transactions.
   3. When the Claim button appears, claim your S on Sonic. Sonic's guide is from 2024, so check the Gateway still lists FTM (Ethereum).
