The race for the fastest, most scalable EVM-compatible blockchain is heating up in 2025, with Monad, SupraEVM, and Sei Network standing out as the three most prominent contenders. Each network takes a unique approach to EVM parallelization, aiming to deliver unprecedented transaction throughput, ultra-low latency, and a developer experience that remains fully Ethereum-compatible. With institutional capital pouring in and DeFi protocols demanding ever-greater performance, the stakes have never been higher.
Why Parallelized EVMs Are Reshaping Blockchain Performance
Traditional Ethereum Virtual Machine (EVM) chains execute transactions sequentially within each block. This design limits throughput and creates bottlenecks for high-volume decentralized applications (dApps), especially those in DeFi and gaming. Parallelized EVMs like Monad, SupraEVM, and Sei Network break this mold by allowing multiple transactions to be processed simultaneously, dramatically increasing speed without sacrificing compatibility or security.
The core idea is simple: if you can safely execute independent transactions in parallel instead of one after another, you unlock massive performance gains. But implementing this at scale while maintaining composability and avoiding conflicts is a non-trivial engineering challenge. Let’s dive into how each chain tackles this problem, and what current benchmarks reveal about their real-world capabilities.
Monad: Optimistic Parallel Execution with MonadBFT
Monad has garnered significant attention for its optimistic parallel execution model paired with a custom consensus protocol called MonadBFT. By rearchitecting both execution and consensus from scratch, rather than simply bolting on parallelism to an existing stack, Monad claims to achieve up to 10,000 transactions per second (TPS) with one-second block times. This is a quantum leap compared to legacy EVM chains.
The secret sauce lies in Monad’s ability to identify which transactions can safely run in parallel using smart dependency analysis. While this approach delivers substantial improvements over traditional sequential processing, recent independent benchmarks suggest Monad’s real-world throughput may fall just short of the industry leaders.

SupraEVM: SupraBTM Sets the Benchmark for Throughput
SupraEVM has emerged as the current frontrunner in terms of raw EVM parallelization performance. The team’s proprietary SupraBTM (Block Transactional Memory) system introduces a conflict-specification-aware architecture that maximizes safe concurrency during transaction execution. According to benchmark reports published by Supra itself, and validated by third-party developers, SupraBTM achieves throughput 1.5 to 1.7 times higher than Monad’s two-phase execution (2PE) model under similar conditions.
This isn’t just marketing spin: Supra has backed up its claims with transparent benchmarking data and even launched a $1 million bounty program inviting developers to test its limits publicly. For projects where maximum TPS is mission-critical, think high-frequency trading platforms or NFT marketplaces, SupraEVM currently leads the pack among EVM-compatible chains.
Sei Network: Sub-Second Finality with Sei Giga Architecture
Sei Network, meanwhile, has carved out its own niche by focusing on ultra-fast finality rather than pure TPS records alone. Its Sei Giga system leverages multi-concurrent producer architecture for highly parallelized execution on an EVM layer one chain. Internal testnet data shows throughput exceeding 5 gigagas per second and transaction finality times below 400 milliseconds, a combination that makes Sei particularly attractive for latency-sensitive DeFi dApps and real-time trading protocols.
This architectural focus on sub-second confirmation times positions Sei as an ideal choice for applications where every millisecond counts, even if its overall TPS doesn’t quite match SupraEVM’s headline figures.
For developers and enterprises evaluating these next-generation EVM-compatible chains, the choice often comes down to specific use case requirements. If your dApp needs the absolute highest throughput for massive transaction volumes, SupraEVM’s SupraBTM engine is currently the benchmark to beat. For latency-critical applications, where instant confirmation is paramount provides Sei Network offers a compelling edge thanks to its sub-400ms finality. Monad, while not topping the charts in every metric, provides a robust middle ground with strong EVM compatibility and a proven ability to scale beyond legacy chains.
Performance Benchmarks: How Do Monad, SupraEVM, and Sei Stack Up?
The latest independent benchmarks paint a nuanced picture of the current landscape:
- SupraEVM: Achieves 1.5, 1.7x higher throughput than Monad’s 2PE model in controlled tests. Supra’s open bounty program and transparent reporting have set a new standard for accountability in performance claims.
- Sei Network: Delivers finality under 400 milliseconds with throughput exceeding 5 gigagas/second, making it ideal for high-frequency DeFi protocols and real-time order books.
- Monad: Consistently hits up to 10,000 TPS with one-second block times under realistic conditions, an enormous leap from traditional EVM chains, but slightly trails SupraEVM in peak parallel execution benchmarks.

Beyond Speed: Developer Experience and Ecosystem Maturity
Raw speed isn’t everything. The true test of these platforms will be their ability to attract developer communities and support complex dApps at scale. Here’s how each chain fares:
- Monad: Maintains full Ethereum compatibility, making it easy for existing Solidity projects to migrate or deploy cross-chain.
- SupraEVM: Offers advanced tooling around its parallel execution model but is still building out broader ecosystem integrations.
- Sei Network: Focuses on a developer-friendly stack with built-in order-matching and high composability for DeFi primitives.
The battle for ecosystem dominance is just as fierce as the race for TPS. Projects that combine technical excellence with strong community support will ultimately shape the future of decentralized finance and Web3 infrastructure.
What’s Next for High-Performance EVM Chains?
The rapid progress of Monad, SupraEVM, and Sei Network signals that EVM parallelization is no longer theoretical, it’s powering live networks today. As more dApps push the boundaries of what’s possible on-chain, expect continued innovation in conflict resolution algorithms, consensus mechanisms, and developer tooling across all three ecosystems.

The bottom line: In late 2025, SupraEVM leads on raw throughput benchmarks; Sei Network is unmatched for instant finality; Monad delivers robust scalability with seamless Ethereum compatibility. Ultimately, your choice should align with your project’s unique demands, and keep an eye on this space as competition continues to drive performance breakthroughs across all three networks.
