1. zkSync Lite balance not claimed

   $146 · 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. Funds in old Ethereum contracts (2015-2021)

   $120 · 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. Mooniswap (1inch) LP tokens

   1. Find your pool with getAllPools() on factory 0xbAF9A5d4b0052359326A6CDAb54BABAa3a3A9643 (v1) or 0x71CD6666064C3A1354a3B4dca5fA1E2D3ee7D303 (v2), and open it in the explorer.
   2. If the LP tokens are staked in a farm, unstake them first.
   3. Call withdraw(amount, minReturns) from your wallet.

5. FTM never moved to Sonic (S)

   Fantom to Sonic

   <$1 · 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).

6. KEEP never swapped to T

   Threshold (KEEP)

   <$1 · 1 position

   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.
