The total value locked (TVL) of the blockchain Sei
$683 million, led by top protocols Yei Finance, Takara Lend and Sailor, reflecting strong momentum for the DeFi ecosystem.
Yei Finance dominates Sei's total value locked with a market share of over 50%, driven by lending features, NFT integrations and strategic liquidity incentives.
Sei's technical innovations such as Twin-Turbo consensus and the upcoming Giga upgrade position it as a high-performance DeFi chain rivaling Solana and Ethereum.
Sei Blockchain, a high-performance layer-1 chain designed specifically for decentralized finance (DeFi) and trading applications, has rapidly emerged in the crypto space thanks to its impressive transaction speed and parallel processing capabilities.
It is often compared to other high-throughput blockchains such as Solana.
According to Defi Llama data, as of July 16, 2025, the total value locked (TVL) in the Sei ecosystem reached approximately $683.73 million, demonstrating strong growth momentum in the DeFi sector.
This article will delve into the top three protocols in terms of total value locked on the Sei blockchain, exploring their functions, contributions to the ecosystem, and significance for Sei's future development - presenting a coherent narrative of the vitality and potential of Sei's DeFi landscape.
SEI Blockchain: Performance Pioneer for DeFi
The Sei blockchain is built on Cosmos SDK and is optimized for DeFi and trading scenarios.
It features a parallel Ethereum Virtual Machine (EVM) compatibility layer, block finality of less than 400 milliseconds, and a potential throughput of up to 200,000 transactions per second (TPS).
Its core innovation lies in 'Twin-Turbo Consensus,' a mechanism that combines high throughput and low latency, enabling it to handle complex on-chain transactions without compromising efficiency.
Additionally, the upcoming Giga upgrade is expected to further enhance performance, aiming to achieve a throughput of 500 million gas per second.
This would make Sei's speed and cost performance comparable to Web2 applications, while maintaining decentralization.
These technical advantages have attracted a significant number of developers and capital, paving the way for the Sei ecosystem for DeFi - as evidenced by the top five protocols in terms of total value locked.
YEI FINANCE: A cornerstone of the capital market
Yei Finance ranks first in the Sei ecosystem with a total value locked of between $381 million and $386 million, representing more than 50% of the network's total value locked.
It serves as the cornerstone of Sei's DeFi landscape. As a non-custodial decentralized money market, Yei Finance offers over-collateralized lending, dynamic interest rate adjustments, and diverse yield opportunities such as staking and liquidity mining.
Its success stems not only from Sei's high throughput and low latency, but also from carefully designed incentive programs.
For example, in late 2024, Yei Finance attracted a massive influx of users through the private beta version of YeiSwap and integration events with YeiLiens NFTs, driving the total value locked from $60 million to nearly $400 million.
Furthermore, the protocol secured $2 million in funding, further cementing its market position.
Its community-driven model and ongoing liquidity incentives have not only boosted user engagement, but also injected steady capital into the Sei ecosystem, becoming a major driver of total value locked growth.
TAKARA LEND: A benchmark for lending efficiency
Takara Lend ranks second with a total value locked of approximately $98.43 million and is another key player in the lending sector within the Sei ecosystem.
As a decentralized, open-source money market, Takara Lend focuses on lending digital assets, taking full advantage of Sei's high-performance architecture to deliver fast and low-cost transaction experiences.
Its design focuses on liquidity and user efficiency, providing a streamlined interface and seamless on-chain operations.
Takara Lend's consistent performance highlights Sei's strength in handling high-frequency financial transactions. Its synergy with Yei Finance reinforces Sei's leading role in the lending market.
By providing reliable lending channels, Takara Lend attracts investors seeking capital efficiency and contributes significantly to the diversification of the Sei ecosystem.
SAILOR: The trading engine of the DEX ecosystem
Sailor, the leading decentralized exchange (DEX) on Sei, ranks third with a total value locked of between $83.24 million and $86.79 million, making it a core trading hub in the ecosystem.
Sailor supports efficient token swaps and generates annual income from trading fees of up to $14.78 million, reflecting high activity within Sei.
Thanks to Sei's parallel processing and low latency, Sailor offers a trading experience close to that of centralized exchanges while maintaining the security and transparency of decentralization.
This high-performance experience has attracted a large number of traders and liquidity providers, leading to increased trading volume on the Sei chain.
Sailor's success not only enhances ecosystem liquidity, but also contributes to Sei's overall total value locked growth through stable trading volume and fee income.
As the liquidity center for the ecosystem, Sailor provides users with a convenient platform for token swapping and provides a foundation for integration with other DeFi protocols.
Growth Drivers and Outlook for the SEI Ecosystem
The total value locked of the Sei blockchain rose from $60.8 million at the beginning of 2024 to nearly $684 million in July 2025 - an increase of more than 10 times - highlighting the explosive development of its DeFi ecosystem.
This achievement is rooted in its technical prowess, ecosystem diversity, and strong community support.
Sei's parallel EVM and Twin-Turbo consensus enable it to excel in handling high-frequency transactions and complex financial scenarios, stimulating the rapid growth of protocols such as Yei Finance and Sailor.
At the same time, the diverse planning of lending protocols, DEXs, and liquid staking caters to different user needs - from yield seekers to liquidity providers - providing rich use cases within the ecosystem.
Support from institutions and the community adds to Sei's momentum. Canary Capital's application for a SEI exchange-traded fund and Sei Labs' continued investment in ecosystem projects indicate strong market confidence in Sei's potential.
Despite a 30% drop in the price of the SEI token in May
Sei blockchain Sei, a high-performance layer-1 chain designed specifically for decentralized finance (DeFi) and trading applications, has rapidly emerged in the crypto space thanks to its impressive transaction speed and parallel processing capabilities.
