1. USDC burned but not minted

   Circle CCTP

   $379 · 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 Arbitrum withdrawal

   Arbitrum One, Arbitrum Nova

   $19 · 1 position

   You withdrew ETH or tokens from Arbitrum to Ethereum but never did the final claim on Ethereum. The challenge period (about 6.4 days) is long over, so the funds can be claimed now.

   1. Open the Arbitrum bridge and connect the receiving wallet.
   2. Open Transactions and find the withdrawal marked Claim, or paste the withdrawal transaction hash.
   3. Press Claim and confirm. You pay the Ethereum gas fee. The funds go to the recipient.

3. Hyphen bridge funds stuck

   Biconomy Hyphen

   <$1 · 2 positions

   Hyphen (Biconomy) is no longer supported. Liquidity provider positions may still be withdrawn from the contracts. Transfers that never arrived need the Biconomy team. We could not confirm this from official docs.

   1. If you provided liquidity, call removeLiquidity with your NFT id on the chain's LiquidityProviders contract on Etherscan (Write tab).
   2. For a farming NFT, first call withdraw(nftId, to) on the LiquidityFarming contract.
   3. If you sent a transfer that never arrived, contact Biconomy; only their executors can release it.

4. Stake in PancakeSwap MasterChef v1

   <$1 · 1 position

   You staked LP or CAKE in the first PancakeSwap farm contract and left it there. The contract still lets you withdraw.

   1. Open MasterChef v1 (0x73feaa1eE314F8c655E354234017bE2193C9E24E) on BscScan and use Write Contract.
   2. Connect the staking wallet and call withdraw(pid, amount) or emergencyWithdraw(pid). For pool 0 (CAKE), use leaveStaking(amount).
   3. Then remove liquidity from the LP token if you want the two coins.
