Depositing tokens to Arbitrum is a straightforward process that allows users to take advantage of lower transaction fees and faster speeds on this popular Layer 2 scaling solution for Ethereum. Whether you're using a desktop or mobile wallet, this guide walks you through the essential steps to securely transfer your assets from Ethereum to Arbitrum—while optimizing for speed, cost, and usability.
Preparing for Your Arbitrum Deposit
Before initiating any deposit, ensure you meet the following prerequisites:
An Ethereum-compatible wallet:
- For desktop: MetaMask is highly recommended.
- For mobile: imToken offers a reliable and user-friendly experience.
- Sufficient ETH balance: You’ll need ETH in your wallet to cover gas fees on the Ethereum network during the deposit process.
Key Considerations
- First-time users should start with ETH: Depositing ETH first ensures you have enough funds on Arbitrum to pay for future transactions, such as token approvals or swaps, which require ETH as gas.
- Gas fees apply on Ethereum: The deposit process incurs network fees paid in ETH. These fluctuate based on Ethereum’s congestion—higher traffic means higher costs.
- Withdrawing back to Ethereum is possible: Simply reverse the transfer direction when moving assets from Arbitrum back to the Ethereum mainnet.
- Multiple bridge options exist: While Arbitrum’s official bridge is secure and trusted, third-party solutions like Hop.exchange and cBridge offer faster withdrawal times and support additional networks.

Choosing the Right Cross-Chain Bridge
When transferring assets to Arbitrum, selecting the appropriate bridge impacts cost, speed, and supported networks.
| Feature | Arbitrum Bridge (Official) | cBridge | Hop.exchange |
|---|---|---|---|
| Fees | Gas fee only | Gas + service fee | Gas + service fee |
| Withdrawal Time | 7–8 days | 5–20 minutes | 5–20 minutes |
| Supported Networks | Ethereum | Avalanche, BNB Chain, Fantom, Optimism, Polygon, etc. | Ethereum, Gnosis, Optimism, Polygon |
While the official Arbitrum bridge offers strong security, its 7–8 day challenge period for withdrawals makes it less ideal for time-sensitive transfers. Third-party bridges like Hop.exchange provide near-instant liquidity at a slightly higher cost.
How to Deposit Tokens via Web Browser (Using MetaMask)
This section guides you through depositing tokens using MetaMask and the official Arbitrum Bridge.
Step 1: Connect Your Wallet
Visit the Arbitrum Bridge and click "Login" to connect your MetaMask wallet. Confirm the connection request in your wallet extension.
Step 2: View Your Balances
Once connected, you’ll see two panels:
- Layer 1 (Ethereum): Your current Ethereum-based assets.
- Layer 2 (Arbitrum): Your Arbitrum wallet balance.
Ensure you’re on the correct network before proceeding.
Step 3: Select Token and Amount
Choose the token you wish to deposit. You can:
- Search by token name or contract address.
- Import custom token lists via "Manage token lists", including popular sources like CoinGecko or CoinMarketCap.
Enter the amount you’d like to transfer. Double-check that you have enough ETH to cover gas fees.
Click "Deposit", then confirm the transaction in MetaMask. The process typically takes around 10 minutes.
You can monitor your deposit status directly on the bridge interface.
Step 4: Confirm Completion
Once the status shows "Success", switch your MetaMask network to Arbitrum to view your deposited tokens.

How to Deposit Tokens via Mobile (Using imToken)
Mobile users can also easily deposit tokens using apps like imToken. Here’s how:
Step 1: Switch Network to Arbitrum
Open your imToken app and tap the network label (e.g., "Ethereum") at the top of the home screen. Scroll down and select Arbitrum to switch your default network.
Step 2: Initiate Deposit
Return to the home screen and tap the "Deposit" button. This will prompt you to choose a bridging service.
Step 3: Connect via Hop.exchange
Select Hop.exchange as your preferred bridge. Tap to open the site in-browser, then click "Connect a Wallet".
Choose "Show More" and select imToken from the list. Your wallet will automatically connect.
Step 4: Complete the Transfer
Select the token and enter the amount you’d like to send. After reviewing details, tap "Send" and approve the transaction in your wallet.
Wait for confirmation—this usually takes under 20 minutes. Once complete, return to your imToken dashboard (on Arbitrum network) to verify the incoming balance.
Frequently Asked Questions (FAQ)
Q: Why do I need ETH on Arbitrum if I’m depositing another token?
A: All transactions on Arbitrum require ETH to pay gas fees. Without it, you won’t be able to swap, approve, or transfer your deposited tokens.
Q: How long does it take to deposit tokens to Arbitrum?
A: Most deposits via official or third-party bridges complete within 10–20 minutes, though network congestion may cause slight delays.
Q: Can I use other wallets besides MetaMask or imToken?
A: Yes! Any EVM-compatible wallet (like Trust Wallet, Rabby, or OKX Wallet) can be used—just ensure it supports Arbitrum network configuration.
Q: Are there risks involved in using third-party bridges?
A: While reputable bridges like Hop and cBridge are generally safe, they carry smart contract risk. Always verify URLs and review security audits before use.
Q: What happens if my deposit doesn’t appear after hours?
A: First, confirm your wallet is set to the Arbitrum network. If still missing, check Arbiscan with your transaction hash to verify completion status.
Q: Is there a minimum or maximum deposit amount?
A: There’s no strict minimum, but very small amounts may not be practical due to gas costs. Maximums vary by bridge—check individual platform limits.
