Innovation and compatibility are now fundamental to the growth and adoption of blockchain networks. Among the various technical concepts gaining traction, "EVM-compatible chain" stands out. While it might seem self-explanatory—blockchain networks that work seamlessly with Ethereum—there's more to explore. Why is EVM compatibility so crucial for the expansion of the crypto world and decentralized applications (dApps)? Let's dive in.
This article breaks down the concept of EVM-compatible chains and examines their vital role in the broader blockchain ecosystem.
Understanding the Ethereum Virtual Machine (EVM)
To grasp EVM-compatible chains, we must first understand the Ethereum Virtual Machine (EVM). The EVM is the runtime environment that executes smart contracts on the Ethereum network. It's a core part of Ethereum, processing code written in Solidity, Ethereum’s native programming language.
The EVM is a decentralized, Turing-complete virtual machine. This means it can perform any computational task as long as it stays within gas limits, ensuring both security and predictability. Ethereum's success is largely due to its ability to support dApps through smart contracts running on the EVM.
What Does EVM Compatibility Mean?
EVM compatibility allows blockchain networks to leverage Ethereum's existing tools and ecosystem. Developers can build and deploy applications across multiple chains, enhancing scalability and reducing congestion on Ethereum.
An EVM-compatible chain is a blockchain that follows the same standards and protocols as Ethereum. These networks can run Ethereum-based smart contracts and dApps without major changes. By adopting Ethereum’s programming languages, transaction formats, and consensus mechanisms, these chains make it easy for developers to migrate their applications.
Key Features of EVM Compatible Chains
Let’s explore the defining characteristics of EVM-compatible blockchains.
Seamless Integration with Ethereum’s EVM
The foundational trait is compatibility with Ethereum’s EVM. These chains are designed to adhere to Ethereum’s standards, rules, and bytecode execution. Smart contracts written in Solidity can be deployed and run on them with little to no modification.
Enhanced Interoperability
EVM-compatible chains promote interoperability across the blockchain space. They enable smooth communication with the Ethereum mainnet, creating a network of connected blockchains. This connectivity supports cross-chain transactions, asset transfers, and data sharing.
Improved Scalability
Scalability is a key advantage. Many EVM-compatible chains tackle Ethereum’s scalability challenges, such as slow transaction speeds and high fees. By offering faster processing and lower costs, they meet the demand for efficient blockchain solutions.
Developer-Friendly Ecosystem
These chains provide a familiar environment for developers. Those experienced with Ethereum can easily adapt, thanks to shared programming languages and tools. This lowers the barrier to entry and encourages more innovation.
Notable EVM-Compatible Blockchains
Here’s a look at some prominent EVM-compatible blockchains and their unique approaches.
Arbitrum
Arbitrum is an EVM-compatible Layer 2 scaling solution for Ethereum. It uses optimistic rollups to process transactions off-chain before settling them on the Ethereum mainnet. This boosts transaction throughput and cuts gas fees while maintaining full compatibility with Ethereum smart contracts.
Key Traits:
- Scalability: Handles transactions off-chain for faster confirmations and lower costs.
- Ethereum Compatibility: Developers can deploy existing smart contracts with minimal changes.
- Interoperability: Fully interoperable with Ethereum, enabling easy asset transfers.
- Security: Leverages Ethereum’s security model through optimistic rollups.
Optimism
Optimism, also known as Optimistic Ethereum, is another Layer 2 solution using optimistic rollups. It processes transactions off-chain and submits them to Ethereum when needed, enhancing scalability and reducing fees.
Key Traits:
- Scalability: Provides high throughput and faster transaction times.
- Full EVM Compatibility: Supports existing Ethereum dApps and smart contracts with ease.
- Decentralization: Maintains security and decentralization by relying on Ethereum’s model.
- Cost Efficiency: Reduces gas fees significantly by processing off-chain.
BNB Chain
BNB Chain, developed by Binance, is a standalone blockchain supporting smart contracts and fast, low-cost transactions. It uses a delegated proof-of-stake (DPoS) consensus mechanism.
Key Traits:
- Scalability: Offers high throughput and lower fees compared to Ethereum.
- EVM Compatibility: Allows easy porting of Ethereum-based applications.
- Interoperability: Cross-chain capabilities enable asset movement between BNB Chain and other networks.
- Ecosystem Integration: Part of Binance’s broad ecosystem, providing access to various services.
These examples highlight how EVM-compatible chains address diverse needs within the blockchain space.
Why Builders Value EVM Compatibility
EVM compatibility is a critical factor for developers choosing where to build their projects. Here’s why it matters.
Access to a Large Developer Community
EVM compatibility connects developers to Ethereum’s vast and experienced community. With abundant resources, documentation, and support, developers can transition smoothly to compatible chains, speeding up development.
Code Reusability
Developers can reuse existing Ethereum smart contracts with minimal changes. This saves time and effort, allowing for quicker deployment and more efficient project scaling.
Cross-Chain Interoperability
EVM compatibility enables applications to interact with both Ethereum and other chains. This opens doors for cross-chain transactions, asset transfers, and data sharing, expanding project possibilities.
Scalability Solutions
Many EVM-compatible chains solve Ethereum’s scalability issues, offering faster transactions and lower fees. This is essential for applications requiring high performance and cost-effectiveness.

Orderly Omnichain and EVM Compatibility
The recent launch of the Orderly Omnichain testnet marks a step toward unifying liquidity across all chains. This innovative infrastructure now supports the EVM ecosystem, allowing builders to create user-centric dApps.
Orderly Omnichain evolves Orderly Network’s vision of a chain-agnostic trading infrastructure. With EVM compatibility, developers can build DEXs with perpetual and spot trading features using a low-latency, shared liquidity central limit order book (CLOB).
For example, a trader on Polygon can transact with users on Arbitrum or Avalanche without leaving Polygon or bridging funds. They simply connect their wallet to a preferred dApp and start trading.
Partnerships with major DeFi ecosystem players underscore this omnichain strategy, fostering a connected and efficient trading environment.
