1. KNCL never swapped to KNC

   Kyber (KNCL)

   $39 · 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.

3. Universe.xyz staked tokens

   $20 · 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.

4. dYdX v3 balance

   $9 · 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 Your USDC can still be taken out through the escape hatch, or withdrawn if already released.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.

5. zkSync Lite balance not claimed

   <$1 · 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.
