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

   $1,011 · 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.

3. STG never swapped to ZRO

   Stargate / LayerZero

   $923 · 1 position

   You hold STG that was never swapped to ZRO. The official redemption site gives 0.08634 ZRO per STG. LayerZero says conversions end on 15 December 2026.

   1. Open the STG Redemption site and connect the wallet that holds STG on Ethereum.
   2. Sign the Terms of Conversion message when asked, approve STG, then confirm the swap.
   3. Do this before 15 December 2026. Conversions are not supported after that date.
   4. Without the site: call swap(stgAmount, signature) on 0x921949cc006A563D76Abd111a3e4c2ACe2C4273f. The signature is of the Terms text.

5. KNCL never swapped to KNC

   Kyber (KNCL)

   <$1 · 1 position

   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.

6. Universe.xyz staked tokens

   $0 · 1 position

   You staked tokens in the Universe.xyz staking contract and never withdrew them. The contract still holds them and lets you withdraw.

   1. Open the staking contract 0x2d615795a8bdb804541C69798F13331126BA0c09 on Etherscan, Write tab, and connect the wallet that staked.
   2. Call withdraw(tokenAddress, amount) with the token you staked and the amount to take out.
   3. emergencyWithdraw(tokenAddress) returns your full balance, but the contract only allows it after 10 epochs with no successful withdraw of that token.
