第2層交易：以較低費用和更快速度交換令牌的綜合指南

加密貨幣行業繼續發展，應對諸如可擴展性，高交易費用和網絡擁塞等重大挑戰。

Layer 2 (L2) solutions have emerged as a crucial innovation in the cryptocurrency industry, addressing the scalability limitations of blockchain networks like Ethereum. These solutions enhance the network's performance by enabling faster and cheaper transactions while maintaining the security and decentralization of the main chain.

第2層（L2）解決方案已成為加密貨幣行業的關鍵創新，解決了以太坊等區塊鍊網絡的可伸縮性限制。這些解決方案通過實現更快，更便宜的交易，同時維持主鏈的安全性和分權性，從而增強了網絡的性能。

In recent years, L2 solutions have gained popularity, particularly among traders seeking to optimize their strategies. By processing transactions off the main blockchain, these solutions significantly reduce gas fees and transaction times, making them ideal for trading tokens.

近年來，L2解決方案已廣受歡迎，尤其是在尋求優化其策略的交易者中。通過處理主要區塊鏈的交易，這些解決方案可大大減少汽油費和交易時間，使其非常適合交易代幣。

In this article, we will delve into the advantages of L2 solutions for token trading, exploring the most popular platforms and discussing strategies to maximize profits.

在本文中，我們將深入研究令牌交易的L2解決方案的優勢，探索最受歡迎的平台，並討論最大化利潤的策略。

What Are Layer 2 Solutions?

什麼是第2層解決方案？

Layer 2 solutions are additional frameworks or protocols that are built on top of an existing blockchain (such as Ethereum) to improve its scalability and efficiency. These networks allow off-chain transaction processing, reducing congestion on the main blockchain.

第2層解決方案是建立在現有區塊鏈（例如以太坊）之上的其他框架或協議，以提高其可擴展性和效率。這些網絡允許鏈交易處理，從而減少了主要區塊鏈的擁堵。

There are several types of L2 solutions, each with its unique approach to enhancing the base layer's capabilities:

有幾種類型的L2解決方案，每種解決方案都採用其獨特的方法來增強基礎層的功能：

✔ Rollups (Optimistic & ZK-Rollups)

✔滾動（樂觀和ZK-Rollups）

✔ State Channels

✔州渠道

✔ Sidechains

Why Trade Tokens on Layer 2?

為什麼要在第2層交易代幣？

1. Lower Transaction Fees

1。較低的交易費用

✔ Ethereum gas fees can be excessively high, especially during periods of high network activity, making trading costly.

✔以太坊汽油費可能過高，尤其是在高網絡活動期間，使交易成本高昂。

✔ L2 solutions allow traders to swap tokens with minimal fees, often below $1 per transaction.

✔L2解決方案使交易者可以以最低的費用交換代幣，通常低於每筆交易$ 1。

Example: A simple swap on Uniswap (Ethereum Layer 1) can cost $20-$50, while the same trade on Arbitrum or Optimism costs less than $1.

示例：對UnisWap（以太坊第1層）的簡單交換可能的價格為$ 20- $ 50，而仲裁或樂觀的相同交易的成本低於1美元。

2. Faster Transactions

2。更快的交易

✔ Layer 2 networks process transactions within seconds, compared to Ethereum’s 10-15 seconds per block.

✔第2層網絡在幾秒鐘內處理交易，與以太坊的每塊10-15秒相比。

✔ Ideal for high-frequency traders and DeFi applications.

✔非常適合高頻交易者和Defi應用程序。

Example: On Polygon, transactions settle almost instantly, compared to Ethereum’s longer confirmation times during high congestion.

示例：與以太坊在高充血期間的更長的確認時間相比，交易幾乎立即定居。

3. Increased Liquidity and Market Efficiency

3。提高流動性和市場效率

✔ Many Layer 2 exchanges and decentralized finance (DeFi) platforms provide deep liquidity pools.

✔許多第2層交換和分散融資（DEFI）平台提供深厚的流動性池。

✔ More traders and lower slippage mean better trade execution.

✔更多的交易者和較低的滑倒意味著更好的貿易執行。

Example: Popular Layer 2 platforms like Arbitrum’s GMX and Polygon’s QuickSwap offer liquidity incentives for traders.

示例：諸如inotum的GMX和Polygon的QuickSwap之類的流行第2層平台為交易者提供流動性激勵措施。

4. Security and Decentralization

4。安全和權力下放

✔ Layer 2 solutions inherit Ethereum’s security, ensuring decentralized and tamper-proof transactions.

✔第2層解決方案繼承了以太坊的安全性，可確保分散和防篡改交易。

✔ Unlike centralized exchanges, Layer 2 does not require users to trust third parties.

✔與集中式交流不同，第2層不需要用戶信任第三方。

Strategies for Trading Tokens on Layer 2

第2層交易令牌的策略

1。第1層和第2層之間的套利

✔ Traders can take advantage of price differences between Ethereum Layer 1 and Layer 2 exchanges.

✔交易者可以利用以太坊第1層和第2層交換之間的價格差異。

✔ Example: If ETH is cheaper on Arbitrum than on Ethereum, a trader can buy on Arbitrum and sell on Ethereum for a profit.

✔示例：如果ETH在仲裁方面比以太坊便宜，則交易者可以在仲裁上購買並在以太坊上出售以獲利。

2. Yield Farming and Staking

2。產生耕作和占有
