Troubleshooting the Arbitrum Bridge: A Checklist for Every Stuck Transfer
Almost every Arbitrum bridge problem is one of four things: the transfer is still confirming, it is waiting for you to press a button, it is inside the seven-day withdrawal window, or it already arrived and your wallet is not showing it. Troubleshooting the Arbitrum bridge is mostly a matter of working out which one you have. The bridge's own history page and a block explorer answer that in about a minute, and the money is almost never lost.
Going in is fast, coming out is slow
A deposit from Ethereum to Arbitrum behaves like an automatic door: ten to fifteen minutes and you are through. A withdrawal back to Ethereum behaves like clearing customs. Arbitrum publishes its results to Ethereum and allows anyone about seven days to challenge them, and only after that can you send a Claim transaction to collect. Nothing is wrong during those seven days, and nobody - not the team, not a support agent - can shorten them.
The checklist, in order
- Look in the right place. MetaMask only shows the network it is set to, and it hides tokens it has not been told about. Switch to Arbitrum and add the token by hand.
- Read the chain, not the app. Paste your address into Arbiscan for Arbitrum or Etherscan for Ethereum and see what actually happened.
- Look for a pending button. Connect the same wallet to the bridge's history page. A Retry or Claim waiting there is the whole problem.
- Check your gas. Funds that arrived but will not move mean you have no ETH on that chain to pay the fee.
When the transfer never confirmed
If the explorer shows your sending transaction still pending on Ethereum, the fee was set too low and the bridge has not seen it at all. Nothing has started, so the fix belongs to the wallet rather than the bridge: speed it up or cancel it in MetaMask and send again at a realistic fee.
Use only the bridge address you typed in yourself, keep a few dollars of ETH on every chain you touch, and set a calendar reminder for day seven when you start a withdrawal. Anyone who contacts you first about stuck funds is running a scam. USDC burned but not minted covers the stablecoin case, and a stuck Arbitrum bridge transaction goes deeper on the Retry step.
