- Sei Network’s DeFi ecosystem surged 67.9% in Q2 2025 as TVL hit $609.4M, proving investor confidence and protocol efficiency.
- Yei Finance and Sailor dominated Sei’s liquidity, driving over $700M combined while smaller protocols added resilience and diversity.
- Early 2025 marked steady growth before April to June triggered exponential momentum, pushing Sei into top DeFi growth ranks globally.
Sei Network’s decentralized finance ecosystem reached a historic milestone as its Total Value Locked (TVL) crossed $609.4 million in Q2 2025. The surge marked an impressive 67.9% growth within a single quarter, according to DeFiLlama data. The network’s rapid expansion highlights how smooth infrastructure and liquidity incentives continue to attract both institutional and retail investors.
Crypto analyst MoonKing noted the shift in sentiment. “$SEI is starting to show what real traction in DeFi looks like,” he posted on X. Hence, Sei’s momentum demonstrates that capital flows naturally when trading and settlement rails operate efficiently. Consequently, the protocol’s growth has positioned it among the fastest-expanding DeFi ecosystems globally.
Protocols Driving Sei’s Expansion
Yei Finance leads Sei’s ecosystem with $365.9 million in locked assets, representing the largest single contributor to the network. Sailor follows closely with $363.8 million in TVL, highlighting intense competition within the ecosystem. Additionally, Takara Lend contributes $71.3 million, securing its role as a mid-tier liquidity hub.
Moreover, DragonSwap accounts for $35.6 million across multiple liquidity pools, reinforcing Sei’s growing exchange infrastructure. Synthetix Protocol maintains $16.2 million, while Stargate Finance holds $12.4 million.
Besides, Yaka Finance adds $9.5 million, with other smaller protocols collectively providing $14.3 million. This layered participation underscores the ecosystem’s concentrated yet diverse structure.
From Stable Growth to Exponential Momentum
Sei’s growth trajectory shifted significantly in early 2025. January showed consistent momentum, while February and March maintained steady expansion. However, April initiated exponential acceleration, with May and June recording the steepest growth curve. Consequently, the ecosystem broke past the $600 million threshold within a concentrated three-month period.
Market conditions throughout 2024 remained relatively calm, creating a foundation for Sei’s explosive 2025 expansion. Furthermore, the network avoided double counting by excluding liquid staking and yield aggregators in TVL methodology, ensuring accurate growth metrics. Hence, the data reflected genuine capital inflows rather than inflated figures.
“Markets move faster on Sei,” MoonKing emphasized, capturing the protocol’s growing reputation for efficiency and adoption.
Sei’s surge highlights its emergence as a serious DeFi contender. Sustained growth could cement its position as a core liquidity hub.
