1. USDC burned but not minted

   Circle CCTP

   $5 · 1 position

   USDC was burned on one chain through Circle CCTP but the matching USDC was never minted on the destination chain. Circle can still sign it, so it can be completed.

   1. Find the burn transaction hash on the source chain.
   2. Get the signed attestation for it from Circle's attestation API (see the Circle CCTP docs).
   3. On the destination chain, call receiveMessage(message, attestation) on the MessageTransmitter contract. You pay the gas fee. USDC goes to the recipient.

2. Polygon zkEVM balance

   $3 · 2 positions

   Polygon zkEVM's sequencer stopped on 1 July 2026. Wallet-held funds not bridged before then can be claimed on Ethereum in a claim UI. Polygon treats unclaimed assets as abandoned after 2027-12-31.

   1. Open the Polygon zkEVM claims site and connect the wallet that held the funds.
   2. Pick your balances and send the claim transaction on Ethereum.
   3. Funds locked inside DeFi contracts are not auto-migrated. Ask Polygon through the forum post.

3. Lisk L2 balance (closing)

   $1 · 2 positions

   Lisk's own chain closes on 2026-10-31. Lisk says withdrawing to Ethereum takes about 8 days, and unstaking LSK adds 3 days. Start now.

   1. Open the Lisk bridge (type bridge.lisk.com yourself) and connect your wallet.
   2. Withdraw your assets to Ethereum. If you staked LSK, unlock it first and wait 3 days.
   3. After the wait, prove and finalize the withdrawal on Ethereum. You pay gas on both chains.

4. Funds on shut-down Swellchain

   Swellchain, Swell

   $1 · 1 position

   Swell closed Swellchain: the final withdrawal deadline was 2026-06-15 and the chain was to run until 2026-06-30. Withdrawals started before 15 June can still be finalized on Ethereum.

   1. If your withdrawal was started before 15 June: after the 7-day proof wait, prove it on the Ethereum OptimismPortal2 0x758E0EE66102816F5C3Ec9ECc1188860fbb87812 (proveWithdrawalTransaction).
   2. Then call finalizeWithdrawalTransaction on the same contract. You pay ETH gas.
   3. If you never started one: Swell said contract withdrawals were possible until 30 June but are technical. Ask Swell support.

5. zkSync Lite balance not claimed

   <$1 · 3 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.

6. Gas deposit in EntryPoint

   ERC-4337 EntryPoint

   <$1 · 1 position

   A smart account or paymaster deposited gas money in the ERC-4337 EntryPoint contract and left it there. Plain wallets can take it out; smart contract accounts often cannot.

   1. Open the EntryPoint contract for your chain and version on the block explorer.
   2. From the deposit account, call withdrawTo with your receiving address and the amount.
   3. If the account is a smart contract, check that it has a function that calls withdrawTo; many do not. Stake needs unlockStake, then withdrawStake.

7. Splits or Zora rewards not withdrawn

   0xSplits, Zora

   <$1 · 1 position

   Money was sent to you through 0xSplits, or you earned Zora creator or referral rewards, and it is still inside the contract waiting for you to withdraw.

   1. Splits: open SplitMain 0x2ed6c4B5dA6378c7897AC67Ba9e43102Feb694EE on Etherscan and call withdraw(account, withdrawETH, tokens[]) with your address. Anyone can call it.
   2. Zora: call withdraw(to, amount) on ProtocolRewards 0x7777777F279eba3d3Ad8F4E708545291A6fDBA8B (same address on Base and other Zora chains), from the account that earned the rewards.
   3. The Splits app (app.splits.org) can also help.

8. MKR never converted to SKY

   Maker / Sky

   <$1 · 1 position

   You hold MKR, or MKR in the old DSChief voting contract, that was never converted to SKY. The converter still works. Its fee is 5% now (read on-chain 2026-10-01) and rises 1 point every 3 months.

   1. Open the Sky app and connect your wallet.
   2. If your MKR is in the old DSChief voting contract, first call free(amount) on that contract.
   3. Approve MKR, then convert it to SKY. You get 24,000 SKY per MKR minus the fee.
   4. Without the app: call mkrToSky(usr, mkrAmt) on the converter 0xA1Ea1bA18E88C381C724a75F23a130420C403f9a.
