Through the course of this article, we will understand all about Layer 2 crypto exchange and the best layer 2 cryptocurrencies in the crypto space.
A secondary framework or system created on top of an existing blockchain system is referred to as Layer 2. The fundamental goal of these protocols is to overcome the transaction speed and scale difficulties that plague the major cryptocurrency networks.
Bitcoin and Ethereum, for example, are still unable to perform thousands of transactions per second (TPS), which will obstruct their long-term growth. Higher throughput is required before these networks can be effectively embraced and used on a larger scale.
What Is A Layer 2 Crypto?
The phrase “layer 2” refers to the various solutions being suggested to the blockchain scalability challenge in this context. The Bitcoin Lightning Network and Ethereum Plasma are two critical examples of layer two solutions. Despite their differences in functioning principles and features, both solutions aim to boost the throughput of blockchain networks.
The Lightning Network is built on state channels, which are connected channels that perform blockchain activities and report them to the main chain. State channels are primarily employed for payment. On the other hand, the Plasma framework comprises sidechains, which are miniature blockchains grouped in a tree-like form.
Layer 2 protocols, in a general context, establish a supplementary framework in which blockchain transactions and operations can take place without relying on layer 1 protocols (main chain). As a result, these solutions are sometimes known as “off-chain” scaling alternatives.
Because the second layer is added as an extra layer, there is no requirement for the main chain to undergo any structural changes when applying off-chain solutions. Layer 2 solutions, as a result, have the ability to provide high throughput without compromising network security.
In other words, much of the work that the main chain would normally do can be delegated to the second layer. Whereas the main chain (layer 1) offers protection, the second layer enables fast throughput, allowing hundreds, if not thousands, of transactions to be completed each second.
What Is Layer 2 Exchange?
Users of decentralized exchanges built on Layer 2 benefit from a variety of features, including no or minimal transaction costs. Aside from that, there’s the settlement speed and vast scalability to consider.
These are made possible by removing transactions from the main blockchain while maintaining security. Layer 2 allows traders on decentralized exchanges to enjoy all of the advantages of a centralized exchange while maintaining control over their assets.
Benefits of Layer 2 Scaling
Layer 2 solutions are important because they allow for scaling and increased throughput while maintaining the Ethereum blockchain’s integrity, providing complete decentralization, clarity, and security while lowering carbon emissions.
Even while Ethereum is the most widely used and possibly the most secure blockchain, it is not without problems. Long transaction times (13 per second) and hefty gas prices are well-known features of the Ethereum Mainnet. Layer 2 transactions are secure, fast, and scalable since they are built on top of the Ethereum blockchain.
Each system has its own set of benefits and drawbacks to consider, such as throughput, gas costs, security, scalability, and performance, to name a few. At the moment, no layer 2 solution can meet all of these requirements. However, layer 2 scaling techniques are known as rollups that try to improve all of these qualities.

Advantages of Layer 2 Crypto
- Order handling is faster than using on-chain solutions.
- There are fewer fees involved than with on-chain alternatives.
- Scalability is comparable to centralized exchanges.
Disadvantages of Layer 2 Crypto
- Adopt the underlying layer 2 solutions’ potential flaws.
5 Best Layer 2 Crypto Exchange
Layer 2 allows traders on decentralized exchanges to access all of the advantages of a centralized exchange while retaining control over their funds. The five best-decentralized exchanges on Layer 2 are listed below.
- Uniswap (v3)
- Uniswap v3 is an update to the previous version (v1,v2), which was released in May. The Ethereum-based decentralized exchange employs the same Automated market maker as the prior v2 model. Apart from that, it offers numerous advantages to the protocol’s consumers and liquidity providers.
- Minimized risks, price slippage elimination or minimization, and assisting traders and liquidity providers in increasing earnings are only a few of its benefits.
- Three major features were released by the protocol developers: concentrated liquidity, oracle feed development, and new fee tiers. The development of Uniswap v3 was necessitated by user complaints about Ethereum blockchain congestion and rising gas fees.
- Traders that offer liquidity can use the concentration liquidity option to specify their price range before depositing liquidity. This means that risk levels will determine their compensation in a liquidity pool.
- Aside from that, the issue with gas prices was resolved with the Uniswap v3 implemented Optimism, a layer 2 scaling solution.
- Also, unlike the v2, swap costs are no longer 0.3%. Fee categories currently range from 0.05%to 0.30% and 1%. The risks increase as a liquidity provider chooses which assets to give to a token pair.
- SushiSwap
- SushiSwap is a fork of Uniswap that is a decentralized exchange. Traders can use the exchange to swap tokens and do other tasks.
- SushiSwap uses smart contracts to complete trades, much like all other decentralized exchanges. Traders can also help others finish deals by providing liquidity.
- SushiSwap uses smart contracts to perform transactions, as previously stated. It’s a computerized market maker.
- Liquidity pools, which contain pairs of tokens necessary to complete deals, are where users of the exchange put their money. Staking and lending options are also available on the site.
- Sushiswap uses the Polygon network to provide users with minimal trading costs and quick processing instead of the Ethereum network’s delays.
Others include:
- QuickSwap
- Dydx
- Curve
The ability to scale these decentralized exchanges is a big reason why traders will want to explore them. These layer 2 exchanges remove the congestion and hefty transaction costs that Ethereum-based exchanges suffer from.
However, traders should keep in mind that to select the best, they must conduct an extensive study. This is due to the fact that things change, and decentralized exchanges add new functionality to their protocols on a daily basis.
