Layer-2: Advantages for Traders
When it comes to gas fees and network congestion, these are fatal "profit killers" for active traders. Layer-2 (L2) refers to scaling solutions built on top of the Ethereum mainnet (Layer-1), which greatly relieve pressure on the main chain by processing large volumes of transactions off-chain. What benefits does this bring to traders?
-
Lower fees: Reduced network congestion leads to significantly lower gas costs.
-
Faster transactions: Near-instant confirmation is crucial in fast-paced futures markets.
-
Enhanced user experience: Deposits and withdrawals become simpler and smoother.
While L2 is often associated with DeFi, NFTs, and gaming, it also benefits CEX users. Fast deposits allow you to seize trading opportunities promptly, while low-cost bridging ensures your capital is deployed into trading more efficiently.

Asset Bridging: Real-World Applications
Bridging, as the name suggests, refers to transferring assets from one blockchain network to another. For traders, this typically means moving assets from the Ethereum mainnet (Layer-1) to a Layer-2 network, or switching between different L2s. The benefits are clear: lower fees, faster transfers, and a more efficient trading experience.
Bridging Basics
During bridging, assets are “locked” on the source chain (e.g., Ethereum mainnet), while corresponding “wrapped tokens” are minted on the destination chain (e.g., Arbitrum). When returning to the source chain, the wrapped tokens on the destination chain are burned, and the original assets are “unlocked” on the source chain.
Example Flow: From Ethereum to Arbitrum to XT.COM
Here’s a detailed step-by-step guide on how to bridge assets from Ethereum to Arbitrum and then deposit them into your XT.COM account:
1. Choose a Supported Bridging Tool
-
I. First, select a bridging tool that supports Arbitrum.
-
II. Recommended tools: Official Arbitrum Bridge (bridge.arbitrum.io) or other reliable third-party services—ensure compatibility with XT.COM.
2. Connect Your Wallet
-
I. Open MetaMask (or another compatible wallet) and switch to the Ethereum network.
-
II. Make sure your wallet holds enough ETH to cover gas fees, which are essential for approving the bridging transaction.
3. Initiate the Bridge Transaction
-
I. On the bridge interface, select Ethereum as the “source chain” and Arbitrum as the “destination chain.”
-
II. Select the token you want to bridge (e.g., ETH, USDT, or other ERC-20 tokens) and confirm the transaction.
-
III. Wait for on-chain confirmation. Once complete, your tokens will appear in wrapped form on the Arbitrum network.
4. Deposit to XT.COM
-
I. Log in to XT.COM and locate your Arbitrum deposit address.
-
II. Send your tokens from your Arbitrum wallet to the XT.COM deposit address.
5. Start Trading!
-
I. Once your tokens arrive in your XT.COM account, you can immediately begin futures trading—no more worrying about high gas fees or long wait times.
-
II. Enjoy faster capital turnover, lower trading costs, and more market opportunities!
