How to Get ETH onto Arbitrum: Step-by-Step Guide

·

Getting Ethereum (ETH) onto the Arbitrum network is a crucial step for users looking to enjoy faster transactions, lower fees, and access to a growing ecosystem of decentralized applications (dApps). Whether you're new to Layer 2 scaling or an experienced DeFi participant, this guide walks you through the process with clarity and precision.

By moving ETH to Arbitrum, you unlock seamless interactions with platforms offering yield opportunities, perpetual trading, and more — all while minimizing gas costs. Let’s dive into how you can set up your wallet and transfer ETH efficiently.

Prerequisite: Set Up a Wallet on Arbitrum

Before transferring ETH, you need a compatible crypto wallet configured for the Arbitrum network. The most widely used option is MetaMask, available as a browser extension or mobile app.

Step 2: Add Arbitrum Network to MetaMask

Once MetaMask is ready, manually add the Arbitrum One network:

  1. Open MetaMask and click the network dropdown (e.g., "Ethereum Mainnet").
  2. Select “Add Network”.
  3. Enter the following details:
  1. Click “Save” to confirm.

You’ve now successfully configured MetaMask for Arbitrum. Switching between Ethereum and Arbitrum is as simple as selecting the network from the dropdown menu.

Getting ETH onto Arbitrum

With your wallet set up, the next step is acquiring ETH on the Arbitrum network. Unlike native Ethereum, Arbitrum requires ETH to be either bridged, withdrawn from an exchange, or purchased directly via a fiat on-ramp.

💡 Pro Tip: Just 0.01 ETH can cover gas fees for approximately 50 transactions on Arbitrum due to its low-cost environment.

Choose the method that best fits your current situation.

Method 1 — Withdraw ETH from a Centralized Exchange

If you already hold ETH on a centralized exchange like OKX, Binance, or Coinbase, this is often the fastest and most cost-effective route.

Many major exchanges support direct withdrawals to the Arbitrum network (listed as “Arbitrum One” or “Arbitrum” under withdrawal options).

Steps:

  1. Log in to your exchange account.
  2. Navigate to Withdraw Crypto.
  3. Select ETH as the asset.
  4. Choose Arbitrum (ARB) or Arbitrum One as the network.
  5. Paste your MetaMask wallet address.
  6. Confirm the transaction.

✅ Advantages: Low fees, fast processing, no bridging delays
⚠️ Note: Always double-check the network — withdrawing on the wrong chain could result in fund loss.

👉 Discover exchanges that support direct Arbitrum withdrawals and move your ETH seamlessly.

Method 2 — Bridge ETH from Another Blockchain

If your ETH is currently on Ethereum Mainnet or another chain like Optimism or Base, you’ll need to bridge it over.

Cross-chain bridges securely transfer assets between networks using smart contracts.

Recommended Bridging Platforms:

These platforms support bridging from:

Bridging Steps (Using Connext as Example):

  1. Visit Connext Bridge.
  2. Connect your MetaMask wallet.
  3. Select Ethereum → Arbitrum.
  4. Enter the amount of ETH to transfer.
  5. Approve the transaction and pay the Ethereum gas fee.
  6. Wait for confirmation — funds typically arrive within minutes.

✅ Advantages: Non-custodial, secure, supports multiple chains
⚠️ Note: Initial bridging incurs Ethereum mainnet gas fees, which can be high during congestion.

Method 3 — Use a Fiat On-Ramp

If you're new to crypto and want to buy ETH directly into your Arbitrum wallet using USD, EUR, or other fiat currencies, a fiat on-ramp is ideal.

While convenient, these services often come with higher fees, regional restrictions, and identity verification requirements.

Steps Using prePO’s On-Ramp:

  1. Go to https://app.prepo.io/ppo
  2. Click the “Cash ⇄ Crypto” option in the dropdown menu.
  3. Follow the prompts to complete KYC (if required).
  4. Select your preferred payment method (e.g., debit card, bank transfer).
  5. Purchase ETH directly into your Arbitrum-connected wallet.

✅ Advantages: No prior crypto needed; beginner-friendly
⚠️ Limitations: Higher fees, transaction limits, and availability varies by region.
