Base layer blockchains like Ethereum experience congestion during peak time. Consequently, cryptocurrency exchange software development faces challenges like low transaction throughput and high gas fees. Layer 2 (L2) scaling solutions can tackle these challenges by processing transactions off the main chain (Layer 1). This blog further explores these solutions and how they benefit crypto exchange development.
Layer 2 Scaling Solutions
Layer 2 scaling solutions are secondary protocols designed to enhance the efficiency and scalability of existing blockchains or layer 1. These solutions aim to boost transaction throughput by moving the majority of transactions off-chain. Prior to attaching the final state back to the main chain, transactions are handled within these secondary levels.
The main goal is to reduce traffic on the main blockchain. Transaction processing is accelerated, and transaction costs are decreased. Blockchain network performance can be improved in a novel way with Layer 2 technologies.

Rollups
Rollups are a layer 2 scaling solution that primarily involves processing transactions off-chain and later submitting a compressed version of the transaction data to the main blockchain (layer 1). There are two main types of Rollups: optimistic and zk-rollups.
Optimistic Rollup
- Involves processing transactions off-chain and then submitting a summary or proof of those transactions to the main blockchain.
- Assumes that the submitted transactions are valid unless proven otherwise. Verification is done on-chain only if a dispute arises.
- Optimistic rollups are known for their flexibility but may involve longer settlement times if disputes occur.
- Examples include Optimism and Arbitrum
ZK-Rollup
- Utilizes zero-knowledge (zk) proofs to create a concise proof of the validity of transactions without revealing the transaction details.
- Provides a higher level of privacy and scalability compared to optimistic rollups.
- Verification on the main chain is more efficient as it involves confirming the validity of the proof.
- Examples include Polygon Hermez and zkSync.
Sidechains
Sidechains are another layer 2 scaling solution that operates independently of the main blockchain. They provide the off-chain execution of smart contracts and transactions. Sidechains therefore improve scalability and lessen congestion.
A two-way bridge connects these independent blockchains to the parent chain or main blockchain. They process transactions faster and for less money. Assets can be moved from the main chain to the sidechain by users.
They improved scalability by processing transactions off-chain. It permits experimenting with various consensus features and procedures without affecting the main chain.
How Layer 2 Solutions Enhance Crypto Exchange Development
Let us understand how layer 2 scaling solutions can enhance crypto exchange development:
Fast Trade Execution
L2 solutions seamlessly handle multiple transactions off-chain using efficient batching and parallel processing. This way users can enjoy fast confirmation time. These scaling solutions lead to a streamlined experience with quick transactions and settlements on crypto exchanges.
Enhanced Interoperability
Many L2 solutions act as bridges between different blockchains and allow users to transfer assets back and forth between the main chain and various L2 sidechains or rollups. This interoperability opens up the possibility of trading assets from different networks on a single exchange and increases liquidity and asset diversity.
Decreased Environmental Impact
Many L2 solutions are built on proof-of-stake (PoS) or hybrid PoS/PoW protocols, which require significantly less energy compared to the traditional proof-of-work (PoW) used by some mainnet blockchains. PoS relies on validators holding and staking tokens to secure the network. This consensus mechanism eliminates the need for energy-intensive mining hardware.
Reduced Fees
L2 scaling solutions effectively lower gas fees in crypto exchange app development by shifting a significant portion of transaction processing off-chain. It optimizes computational load, implements batch processing, and introduces efficiencies in smart contract execution. These strategies collectively contribute to a more cost-effective and scalable transaction environment.
Upgraded Scalability
Layer 2 solutions allow crypto exchanges to scale operations more efficiently. They strategically process a substantial volume of transactions off-chain and periodically settle the aggregated results on the main chain. Since the main chain does not have the burden of processing every transaction, L2 scaling solutions foster a more scalable and responsive ecosystem for trading.
Customizable Security Model
The customizable security model offered by L2 solutions is a crucial advantage for crypto exchange development. It enables developers to cater to diverse needs and priorities. Various layer 2 scaling solutions offer different levels of security.
Improved Transaction Throughput
Layer 2 solutions play a pivotal role in boosting the transaction throughput of a crypto exchange. It efficiently diverts a portion of transactions away from the main blockchain.
Improved User Experience
L2 solutions can remove the complexity of underlying blockchain technology and allow for the development of more user-friendly and intuitive crypto exchange interfaces. This reduces the learning curve for new users and makes trading more accessible to a wider audience.
Additionally, better scalability, high throughput, and low fees lead to better user experience.
