Sei (SEI) has rapidly emerged as one of the most promising Layer-1 blockchains in the evolving Web3 landscape. Built on the Cosmos SDK and optimized for digital asset trading, Sei is engineered to solve long-standing issues in decentralized finance (DeFi) and blockchain gaming—namely speed, scalability, and developer accessibility. With its recent upgrade to Sei V2, the network now boasts EVM compatibility, parallel transaction processing, and a growing ecosystem backed by a $120 million Ecosystem Fund.
But what truly sets Sei apart from competitors like Ethereum and Solana? And why are developers and gamers increasingly migrating to this high-performance chain?
This comprehensive analysis explores Sei’s architecture, core innovations, tokenomics, staking mechanics, and burgeoning DeFi and gaming ecosystems—all while highlighting key opportunities for users and investors in 2025.
What Is Sei (SEI)?
Sei is a high-throughput Layer-1 blockchain designed specifically for decentralized exchanges (DEXs) and trading applications. Launched in August 2023 by co-founders Jeffrey Feng and Jayendra Jog, Sei leverages the Cosmos SDK to deliver exceptional performance, achieving up to 12,500 transactions per second (TPS) with finality in just 400 milliseconds.
Dubbed the “Solana killer” by some industry observers, Sei outperforms many existing blockchains in transaction speed and efficiency—especially during peak network activity. Unlike traditional chains that process transactions sequentially, Sei uses parallel execution, enabling multiple transactions to be confirmed simultaneously without bottlenecks.

This architectural advantage makes Sei particularly well-suited for applications requiring real-time execution, such as DEXs, prediction markets, and fast-paced blockchain games.
The Team Behind Sei
Sei Labs, the core development team behind the network, was founded in 2021 with a vision to build a blockchain optimized for order-matching and high-frequency trading. Co-founder Jayendra Jog, a Silicon Valley native with deep roots in tech innovation, recognized early on that most blockchains were not built with trading efficiency in mind.
He partnered with Jeffrey Feng (also known as GigaJeff), who brought experience from top-tier financial institutions like Goldman Sachs and Coatue Management. Together, they assembled a world-class team including:
- Mike McCoy – Director of Infrastructure (ex-Protocol Labs, ConsenSys)
- Giga Chad Hugghins – Head of Community (formerly at Polygon)
- Jack Lipstone – Head of DeFi Business Development (ex-Chapther One)
Their combined expertise in blockchain infrastructure, decentralized finance, and community growth has positioned Sei as a serious contender in the Layer-1 race.
Key Features of Sei V2
Launched in July 2024, Sei V2 marked a major leap forward for the network. It introduced full Ethereum Virtual Machine (EVM) compatibility, allowing Ethereum-native developers to deploy smart contracts seamlessly on Sei with minimal code changes.
Beyond EVM support, Sei V2 achieved several critical milestones:
- Over $250 million in Total Value Locked (TVL)
- More than 400,000 daily active addresses
- 150+ mainnet projects live
- Over 6.5 million total users
These metrics underscore Sei’s rapid adoption and growing developer traction.
EVM Compatibility: Bridging Ethereum’s Developer Gap
One of Sei’s most strategic moves was integrating EVM compatibility. This allows developers familiar with Solidity and Ethereum tooling to transition smoothly—without learning new languages or frameworks.
While many high-speed blockchains sacrifice developer familiarity for performance, Sei delivers both. By supporting EVM, Sei opens its doors to thousands of existing DeFi protocols, NFT platforms, and Web3 tools looking for faster, cheaper alternatives to Ethereum.
However, the standard EVM isn’t built for ultra-high throughput. Most EVM-based chains cap out at around 100 TPS, far below what modern applications require. In contrast, web2 platforms like Visa process over 65,000 TPS during peak times.
To overcome this limitation, Sei introduced GigaGas—a performance metric representing billions of gas units processed per second.
Sei aims to achieve 5 gigagas per second, a 50x improvement over current EVM chains. This breakthrough could enable complex on-chain games, real-time financial markets, and AI-driven dApps previously impossible on slower networks.
Move Programming Language: Security Meets Efficiency
Sei also supports the Move programming language, originally developed for the Aptos and Sui blockchains. Move is designed specifically for secure smart contract development, reducing vulnerabilities common in general-purpose languages like Rust (used by Solana).
By combining Move with EVM compatibility, Sei offers developers flexibility: use Solidity for rapid deployment or Move for enhanced security and resource management.
Sei vs. Solana: What’s the Difference?
At first glance, Sei and Solana appear similar—both are high-speed Layer-1 blockchains targeting DeFi and gaming. However, their underlying architectures differ significantly.
| Feature | Solana | Sei |
|---|---|---|
| Transaction Processing | Sequential (single global state) | Parallel execution |
| Average TPS | ~4,000–65,000 (theoretical) | Up to 12,500 TPS |
| Finality Time | ~2.5 seconds | ~400 milliseconds |
| Smart Contract Language | Rust | Solidity (EVM), Move |
| Developer Accessibility | Steep learning curve | High (EVM-compatible) |
Solana processes transactions one after another using a single-threaded model. During congestion, this can lead to network slowdowns and volatile gas fees.
Sei, on the other hand, uses parallelization to execute non-conflicting transactions simultaneously. This reduces latency and prevents network gridlock—even under heavy load.
For example, if Alice sends SEI to Bob while Charlie swaps tokens on a DEX, these two actions don’t interfere and can be processed in parallel. On Solana, they’d wait in line behind each other.
This makes Sei inherently more scalable and stable during high-demand periods.
Gaming on Sei: The Rise of GameFi
Sei has become a hotspot for blockchain gaming innovation. Its speed and low fees make it ideal for real-time play-to-earn (P2E) games and interactive metaverse experiences.
The ecosystem includes:
- Botwars Ascendance – A competitive strategy game with NFT rewards
- Heroes of Holdem – Blockchain poker with real token payouts
- MetaArena – Multiplayer combat game with dynamic economies
In addition to individual titles, Sei hosts full gaming platforms like:
- Good Game Arcade
- KAP Games
- GameBuild – A no-code platform enabling users to create their own blockchain games
A major milestone was the launch of Gaming on Sei – The Arcade, featuring 26 integrated games at launch. Another highlight was GPT Wars, touted as the first AAA shooter built natively on a blockchain.
Sei games also gained recognition at the Blockchain Game Awards 2024, where several projects received nominations for innovation and gameplay design.
