近年来，L2解决方案已广受欢迎，尤其是在寻求优化其策略的交易者中。通过处理主要区块链的交易，这些解决方案可大大减少汽油费和交易时间，使其非常适合交易代币。

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，我们将深入研究令牌交易的L2解决方案的优势，探索最受欢迎的平台，并讨论最大化利润的策略。

What Are Layer 2 Solutions?

什么是第2层解决方案？

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层解决方案是建立在现有区块链（例如以太坊）之上的其他框架或协议，以提高其可扩展性和效率。这些网络允许链交易处理，从而减少了主要区块链的拥堵。

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

有几种类型的L2解决方案，每种解决方案都采用其独特的方法来增强基础层的功能：

✔ Rollups (Optimistic & ZK-Rollups)

✔滚动（乐观和ZK-Rollups）

✔ State Channels

✔州渠道

✔ Sidechains

Why Trade Tokens on Layer 2?

为什么要在第2层交易代币？

1. Lower Transaction Fees

1。较低的交易费用

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

✔以太坊汽油费可能过高，尤其是在高网络活动期间，使交易成本高昂。

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

✔L2解决方案使交易者可以以最低的费用交换代币，通常低于每笔交易$ 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：对UnisWap（以太坊第1层）的简单交换可能的价格为$ 20- $ 50，而仲裁或乐观的相同交易的成本低于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层网络在几秒钟内处理交易，与以太坊的每块10-15秒相比。

✔ Ideal for high-frequency traders and DeFi applications.

✔非常适合高频交易者和Defi应用程序。

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

示例：与以太坊在高充血期间的更长的确认时间相比，交易几乎立即定居。

3. Increased Liquidity and Market Efficiency

3。提高流动性和市场效率

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

✔许多第2层交换和分散融资（DEFI）平台提供深厚的流动性池。

✔ More traders and lower slippage mean better trade execution.

✔更多的交易者和较低的滑倒意味着更好的贸易执行。

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

示例：诸如inotum的GMX和Polygon的QuickSwap之类的流行第2层平台为交易者提供流动性激励措施。

4. Security and Decentralization

4。安全和权力下放

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

✔第2层解决方案继承了以太坊的安全性，可确保分散和防篡改交易。

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

✔与集中式交流不同，第2层不需要用户信任第三方。
