1. Unclaimed Arbitrum withdrawal

   Arbitrum One, Arbitrum Nova

   $20 · 2 positions

   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.

2. USDC burned but not minted

   Circle CCTP

   $10 · 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.

   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.

   3. Funds locked inside DeFi contracts are not auto-migrated. Ask Polygon through the forum post.
