1. USDC burned but not minted

   Circle CCTP

   $1,500 · 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. Unclaimed Polygon PoS withdrawal

   Polygon PoS bridge

   $1,329 · 1 position

   You burned tokens on Polygon to withdraw to Ethereum, and the checkpoint is done, but the exit was never run on Ethereum. The tokens wait in the bridge.

   1. Open Polygon Portal and connect the wallet that withdrew.
   2. Find the withdrawal in your transactions and press Initiate Claim.
   3. Approve in your wallet, then press Claim Tokens. Pay the Ethereum gas fee. The tokens go to the burner address.

3. Gas deposit in EntryPoint

   ERC-4337 EntryPoint

   $10 · 2 positionsMay not work

   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.
