Sei Network is a high-performance Layer 1 blockchain purpose-built for decentralized finance (DeFi) and trading applications. Built on the Cosmos SDK, Sei delivers fast transaction finality, low latency, and a native order-matching engine that significantly enhances the trading experience for DeFi protocols. With interoperability enabled by IBC (Inter-Blockchain Communication), Sei is positioning itself as a leading infrastructure layer for decentralized exchanges and other trading-centric applications in the Web3 ecosystem.
As blockchain technology evolves, so does the demand for speed, scalability, and seamless user experiences—especially in DeFi. Sei meets these demands by combining cutting-edge architecture with developer-friendly tools, making it an ideal environment for innovative dApps to thrive.
Top DeFi Protocols on Sei Network
Yei Finance: Powering Lending and Borrowing
Yei Finance stands as the largest decentralized lending protocol on the Sei network. It supports major assets such as SEI, USDT, USDC, WETH, and FRAX, enabling users to earn yield by depositing their holdings or access liquidity through over-collateralized loans and flash loans.
With the launch of Yei v1, new functionalities like cross-chain bridges, flash loans, and e-mode (efficiency mode) have been introduced. These features expand use cases for developers and traders alike, enhancing capital efficiency while maintaining robust security standards. E-mode, in particular, allows users to borrow more against correlated assets, reducing collateral requirements without compromising system stability.

DragonSwap: The Native DeFi Hub
DragonSwap serves as Sei’s native DeFi hub, offering an automated market maker (AMM), prediction markets, and support for Liquid Staking Tokens (LSTs). Designed with a user-first and community-driven philosophy, DragonSwap has emerged as one of the highest-performing parallelized liquidity hubs running on Sei V2.
Its AMM model ensures efficient price discovery and minimal slippage, while the integration of prediction markets opens up novel ways for users to express market sentiment and earn rewards. By supporting LSTs, DragonSwap also enables stakers to maintain liquidity while earning staking yields—a key innovation in modern DeFi.
Jellyverse: Building the Future of DeFi 3.0
Jellyverse is a comprehensive ecosystem within the Sei network and the exclusive Balancer partner on this chain. It integrates a decentralized exchange (DEX), staking protocols, and synthetic asset frameworks—all focused on advancing DeFi capabilities.
Positioned as a top-tier DeFi 3.0 platform, Jellyverse aims to create a sustainable, yield-driven environment where users can gain exposure to both synthetic and non-synthetic real-world assets (RWAs). This bridges traditional financial value with blockchain-based innovation, unlocking new investment opportunities in a trustless setting.
By leveraging Balancer’s advanced pool mechanics, Jellyverse supports customizable liquidity pools and passive income strategies that appeal to both retail and institutional participants.
Pit Finance: Maximizing Yield Potential
Pit Finance is a decentralized yield optimizer tailored specifically for the Sei network. Its mission is to unlock the full earning potential of crypto assets by automating complex yield-generating strategies across various protocols.
Through intelligent vaults and compounding mechanisms, Pit Finance reduces manual effort for users while increasing returns. Whether you're depositing stablecoins or volatile assets, Pit Finance dynamically allocates capital to the most profitable opportunities across Sei’s growing DeFi landscape.
While its documentation remains accessible externally, the protocol operates transparently within the SeFi ecosystem, emphasizing security audits and community governance.

Onlyperps: High-Speed Perpetual Trading
Onlyperps is a decentralized spot and perpetual contracts exchange built on Sei v2. It offers low trading fees and minimal price impact thanks to its high-throughput architecture and multi-asset pool design.
Traders benefit from leveraged positions and efficient market-making tools, while liquidity providers earn consistent fee income from trading activity. The platform's performance shines under high-frequency conditions—precisely where Sei’s parallelization advantages come into play.
As interest in perpetual futures grows within decentralized environments, Onlyperps provides a secure, scalable solution that rivals centralized exchanges in speed but retains full user custody.
Silo: Liquid Staking and MEV Infrastructure
Silo plays a foundational role in the Sei ecosystem as the leading provider of liquid staking and MEV (Maximal Extractable Value) infrastructure. By allowing users to stake their SEI tokens and receive tradable liquid staking tokens in return, Silo increases capital efficiency across the network.
These LSTs can be used across other DeFi platforms—such as DragonSwap or Jellyverse—for additional yield generation. Meanwhile, Silo’s MEV solutions ensure validators are incentivized fairly while minimizing negative impacts on transaction ordering for end users.
This dual focus strengthens network security and improves overall economic alignment between participants.
Why Build and Use Dapps on Sei?
Sei’s technical edge comes from its parallelized transaction processing engine and built-in orderbook logic—features rare among general-purpose blockchains. This makes it uniquely suited for order-heavy applications like exchanges, prediction markets, and high-frequency trading protocols.
Additionally, Sei’s compatibility with IBC enables seamless asset transfers across the Cosmos ecosystem, increasing liquidity reach and user accessibility. Developers benefit from modular tooling via Cosmos SDK, while users enjoy faster confirmations and lower costs compared to congested networks like Ethereum.
