   3. Wait out the challenge period (the page shows the time left).
   4. Press Finalize. You pay the network gas fee. The funds go to your address.

3. USDC burned but not minted

   Circle CCTP

   $9 · 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.

4. Polygon zkEVM balance

   $5 · 1 position

   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.

5. MATIC never swapped to POL

   2. Approve the upgrade contract to use your MATIC.
   3. Confirm the migrate transaction to receive POL. You pay Ethereum gas.
