1. Hop transfer not received

   Hop Protocol

   $349 · 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.

2. dYdX v3 balance

   $287 · 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 Your USDC can still be taken out through the escape hatch, or withdrawn if already released.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.

3. PoolTogether deposit still in pool

   $24 · 1 position

   You deposited into a PoolTogether v3 or v4 prize pool and never withdrew. Your deposit is still in the pool contract.

   1. Open the prize pool contract (prize_pool address) on the block explorer.
   2. v4: call withdrawFrom(from, amount) with your address. v3: call withdrawInstantlyFrom(from, amount, controlledToken, maximumExitFee).
   3. v3 can charge an early-exit fee. Confirm and check your wallet.

4. zkSync Lite balance not claimed

   $13 · 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.

5. Expired Element Finance position

   $9 · 1 position

   You hold Element v1 principal tokens (PT), yield tokens (YT) or pool shares. All tranches have ended, so they can be redeemed.

   1. Open the tranche contract (tranche_or_pool column) on Etherscan, Write Contract tab.
   2. PT: call withdrawPrincipal(amount, to). YT: call withdrawInterest(amount, to). Both only work after the tranche expiry.
   3. LP shares: exit the Balancer pool with exitPool first, then redeem as above.

6. Plasma pre-deposit vault shares

   Plasma (XPL pre-deposit vault)

   $4 · 1 position

   You hold shares of the Plasma USD Vault from the XPL sale or later deposits. They are still unredeemed and can be withdrawn for USDT0.

   1. Open the Plasma dashboard, connect your wallet and look for the vault in Portfolio or Savings.
   2. Press Withdraw on the vault and confirm. We could not confirm the exact screen for pre-deposit vault shares.
   3. On Ethereum: shares first need to be bridged to Plasma with the Teller contract.

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

   <$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.

8. 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.
