Повний посібник із додавання мережі Arbitrum до MetaMask: підключення до майбутнього другого рівня
Arbitrum, a leading Ethereum Layer 2 scaling solution, has attracted a massive following of users and developers thanks to its lightning-fast transaction speeds and ultra-low network fees.
As of January 9, 2026, its native governance token, ARB, is priced at $0.21 on Gate, with a market capitalization exceeding $1.19 billion—clear evidence of the ecosystem’s ongoing vitality.
This article offers a comprehensive guide on how to add the Arbitrum network to your MetaMask wallet. You’ll also learn how to securely and conveniently transfer assets from Gate to Arbitrum, empowering you to seamlessly explore the network’s vast array of DApps and airdrop opportunities.
01 Understanding Arbitrum: Why Add This Network?
Before diving into the technical steps, it’s essential to grasp the value of Arbitrum. Unlike a standalone blockchain, Arbitrum is a Layer 2 scaling solution built on top of Ethereum.
Its core mission is to address the persistent congestion and high gas fees that have long plagued the Ethereum mainnet.
Leveraging a technology called Optimistic Rollup, Arbitrum processes the computation and storage of large volumes of transactions off-chain, submitting only the final results back to Ethereum for secure validation.
This design delivers two major benefits: transactions are confirmed almost instantly, and costs are dramatically lower—often just a fraction of Ethereum’s mainnet fees.
For users, this means you can trade tokens, participate in DeFi mining, mint NFTs, and enjoy Ethereum-grade security on Arbitrum, all at nearly zero cost.
As of January 9, 2026, the total value locked in the Arbitrum ecosystem is close to $1.5 billion, cementing its position as a leader in the Layer 2 space. Its network effects and wealth-building opportunities continue to grow rapidly.
02 Two Core Methods to Add Arbitrum to MetaMask
Integrating the Arbitrum network into your MetaMask wallet is the first step to exploring its ecosystem. There are two mainstream, secure methods to choose from: a fully automated shortcut and a manual configuration for those who prefer more control.
Method 1: One-Click Addition via Chainlist (Recommended)
This is the fastest and most error-proof method, especially for beginners.
Chainlist is a trusted website that aggregates blockchain network information and comes recommended by MetaMask. Simply visit chainid.network, connect your MetaMask wallet, enter "Arbitrum One" in the search box, and click the "Add to MetaMask" button. Your wallet will prompt you for confirmation; approve, and the network will be added automatically.
The advantage here is that all network parameters (such as RPC URL and Chain ID) are pre-verified, so you don’t need to enter anything manually, eliminating the risk of connection failures due to incorrect settings.
Method 2: Manually Add Network Parameters
If you prefer hands-on control or if Chainlist is temporarily unavailable, manual addition is a reliable alternative. Open the network list in MetaMask, select "Add Network," and enter the following official parameters provided by Arbitrum:
- Network Name:
Arbitrum One - New RPC URL:
https://arb1.arbitrum.io/rpc - Chain ID:
42161 - Currency Symbol:
ETH - Block Explorer URL:
https://arbiscan.io/
Once you save these settings, "Arbitrum One" will appear in your MetaMask network dropdown menu. Note: Adding a network on your mobile device does not automatically sync to the browser extension, and vice versa—you’ll need to add it separately on each device.
03 Depositing Assets to Arbitrum from Gate
After adding the network, your Arbitrum wallet balance will show zero. You’ll need to inject some "fuel" from outside to start interacting. Withdrawing directly from a centralized exchange like Gate is currently the most popular and convenient way to fund your wallet.
Let’s use ETH (the primary currency and gas token on Arbitrum) as an example—the process is straightforward:
- Log in to your Gate account and navigate to the withdrawal page.
- Select ETH as the withdrawal asset.
- When choosing the withdrawal network, it’s crucial to select "Arbitrum One" or "Arbitrum."
- Paste the receiving address you copied from your MetaMask wallet (set to the Arbitrum network), confirm the amount and fee, then submit the withdrawal request.
Safety Tip: Always double-check that you’ve selected Arbitrum as the withdrawal network. If you mistakenly choose "ERC-20" (Ethereum mainnet), your assets won’t be lost, but they’ll be sent to the same address on Ethereum’s mainnet.
In that case, you’ll face high Ethereum gas fees and need to use a cross-chain bridge to move your assets to Arbitrum—a process that’s both complex and costly.
04 Getting Started on Arbitrum: Basic Operations and Advanced Exploration
Once your assets appear in your MetaMask Arbitrum balance, the real adventure begins. You can dive into Arbitrum’s thriving DeFi ecosystem—try decentralized exchanges like SushiSwap or the native leader, Camelot, to swap ETH for other ecosystem tokens.
Whenever you connect to any DApp, make sure MetaMask is set to "Arbitrum One" at the top.
Some projects, such as Uniswap, are also deployed on Arbitrum, offering a superior trading experience compared to the mainnet. Advanced users can explore Arbitrum’s unique yield farms, NFT marketplaces, and blockchain games.
A key technical detail: every operation on Arbitrum—whether it’s trading, approving, or staking—requires gas fees paid in ETH. Always keep a small amount of ETH in your wallet as "fuel," which is why withdrawing ETH from Gate is the most direct way to get started.
Looking Ahead
Once your first assets arrive from Gate to your Arbitrum address in MetaMask, that subtle change in your wallet balance marks more than just a completed transfer. Data shows that daily transaction volumes on Arbitrum consistently exceed $90 million, with high on-chain address activity.
On native DEXs like Camelot, new assets not yet listed on major exchanges are brewing the next wave of market narratives. The quiet ETH balance in your wallet is now connected to this high-speed, low-cost value network—ready to be activated with every interaction you make.
