2. USDC burned but not minted

   Circle CCTP

   $22 · 2 positions

   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.

3. zkSync Lite balance not claimed

   $8 · 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.
