Bridged Ether From Ethereum to Arbitrum but Stuck on Pending?
A deposit from Ethereum to Arbitrum normally lands in about ten to fifteen minutes, and almost every one that looks stuck on pending is simply still inside that window. Plain ETH is credited to your address automatically - there is no button to press and no step you can miss. If an hour has gone by and nothing has arrived, the problem is nearly always on the Ethereum side, not the Arbitrum side.
Why does a deposit take minutes instead of seconds?
A bridge does not move your Ether anywhere. It locks it in a contract on Ethereum and credits a matching amount to you on Arbitrum. Think of an airport currency desk: they take your notes, hold them in the drawer, and hand you the other currency. Two separate events, with a gap between them. The gap here is the time Ethereum needs to confirm your deposit and the time Arbitrum needs to see that it happened.
What is actually holding it up?
- The Ethereum transaction has not confirmed. If you set a low fee, your deposit is still queued on Ethereum and Arbitrum has nothing to react to yet. Check the hash on Etherscan first.
- The wallet is on the wrong network. The Ether arrived, but MetaMask is still pointed at Ethereum, so the balance reads zero. Switch to Arbitrum One.
- It is a token, not Ether. ERC-20 deposits such as USDC travel as a retryable ticket, which can fail to redeem itself and then needs a manual Retry on the bridge site. Ether never does.
Where to look instead of refreshing
Open the transaction history on the Arbitrum bridge site with the same wallet connected. It shows each deposit and the step it has reached, which beats guessing from an empty balance. If the bridge lists it as complete, check your address on Arbiscan - the explorer is the record, and the wallet is only a viewer.
One habit saves most of this pain: bridge a tiny amount first and watch it arrive before sending the rest. And nobody legitimate will message you offering to release a pending deposit. Anyone asking for your seed phrase is stealing, no matter how official the profile looks. For the wider picture on delays, see why cross-chain transfers stall, and a stuck Arbitrum bridge transaction covers the token case in detail.
