Yei Finance Launches DeFi App Clovis on the Sei Network

Yei Finance leads Sei Network DeFi with $300M TVL, offering efficient lending, trading, and bridging through low-cost, high-speed infrastructure.

Clovis, Yei Finance’s new product, aims to unify cross-chain liquidity, reducing fragmentation and costs while enabling faster, near-CEX trading experiences.

With modular DeFi services, security audits, and developer tools, Clovis positions itself as a cross-chain operating system for the evolving multi-chain DeFi landscape.

Decentralized finance (DeFi) is reshaping global finance at high speed. Sei Network, a high-performance Layer-1 optimized for trading and financial apps, is rising fast as a frontier for DeFi innovation. In this ecosystem, Yei Finance has become the top decentralized application (dApp) on Sei by total value locked (TVL).

As of September 2025, TVL reached $300 million, showing strong market traction. Building on this base, Yei Finance launched its evolved product, Clovis. Its goal is to connect liquidity across chains and build a DeFi operating system for multiple networks. At the same time, the native token CLO began a token generation event (TGE) airdrop in September 2025, adding new energy to the ecosystem

YEI FINANCE: THE DEFI FOUNDATION OF SEI NETWORK

Yei Finance is a non-custodial money market protocol on Sei. It offers diverse yield options and uses Sei’s high-performance design to deliver low cost and high efficiency. Sei’s dual-turbo consensus brings average block time down to about 0.5 seconds, far faster than Ethereum’s 12 seconds.

Throughput is higher. Its parallelized EVM stack lets many transactions process at the same time, keeping gas fees under $0.01 per transaction. The built-in centralized limit order book (CLOB) improves transparency. On-chain order matching reduces front-running and maximum extractable value (MEV) risk. These strengths help Yei Finance stand out on Sei and act as a solid bridge between users and DeFi opportunities

Yei Finance is designed around user needs. It covers lending, trading, and cross-chain bridging for both retail users and professionals. The core module, YeiLend, lets users deposit major crypto assets (such as Bitcoin and Ethereum), liquid restaking tokens (like Lido’s stETH), and liquid staking tokens (like Rocket Pool’s rETH) to earn variable interest based on supply and demand.

According to Yei Finance’s website, when borrowing demand is high, deposit APY can reach 5%–10%. A portion of interest flows to the protocol treasury to support long-term growth. To reduce risk, YeiLend uses isolated lending pools so one asset’s volatility does not create system-wide risk. For example, if ETH price drops sharply, only the related pool triggers liquidations while other pools stay stable. This protects user funds and increases resilience.

YeiSwap is the DEX module of Yei Finance. It lets users swap assets across chains. Liquidity providers can add liquidity to pairs (such as SEI/USDC or ETH/BTC) and earn a 0.3% fee per trade, lending interest, and extra YeiSwap rewards. Its cross-chain power uses Sei’s batch deposit tech to move assets from Ethereum, Polygon, and others to Sei quickly.

Costs are 30%–50% lower than traditional bridges like Wormhole. Recently, Yei Finance launched a “double rewards program” for high-liquidity pairs (such as SEI/CLO), adding ~2% extra annual yield and attracting more liquidity providers. Bridging features add convenience.

With a simple interface (supporting MetaMask, Keplr, etc.), users can move assets from Cosmos chains or other EVM chains to Sei in 3–5 seconds. Fees can be under $0.05. This smooth cross-chain flow comes from Sei’s compatibility with the IBC protocol, giving users a seamless transfer experience

Security and technical hardening are another strength. The protocol passed strict audits by firms such as PeckShield and CertiK. Smart contracts passed 95% of security tests, with no major bugs found. Formal verification further lowers logic risk. An advanced liquidation protection mechanism adds safety. When collateral nears the liquidation line, the system alerts users to add collateral and offers a 24-hour grace period to reduce forced-sale loss. Yei Finance also introduces tokenized collateral. Users can convert collateral (like ETH) into a tokenized asset (like yETH) and keep using it in other DeFi scenarios. This raises capital efficiency. These steps build user trust and prepare Yei Finance for a more complex ecosystem.

CLOVIS: A CROSS-CHAIN DEFI OPERATING SYSTEM BLUEPRINT

On September 4, 2025, Yei Finance announced Clovis. This marks a shift from a single-chain dApp to a cross-chain DeFi operating system. It shows Yei Labs’ view of where DeFi is going. Clovis aims to integrate Sei’s CLOB and parallelized EVM to build a cross-chain liquidity hub. It will connect Ethereum, Polygon, BNB Chain, and other major blockchains.

The goal is to fix DeFi’s long-standing liquidity fragmentation. In a multi-chain world, user assets sit on many chains. This lowers efficiency and raises costs. Clovis wants to give users one liquidity entry point and a smooth cross-chain experience. Like Ethereum did for smart contracts, Clovis wants to be an “operating system” for DeFi

Cross-chain liquidity integration is the most notable feature. With Sei’s bridging and CLOB design, Clovis lets users move and trade assets across chains in near real time. For example, users can deposit DAI from Ethereum into a Clovis liquidity pool and then lend or trade directly on Sei. They do not need complex bridging steps. Industry analysis suggests Clovis’s batch processing can cut cross-chain costs by 40%.

Trade confirmation can drop to 2–3 seconds, better than many traditional bridges. This speed creates arbitrage chances. A trader might buy UNI cheaper on Ethereum and sell higher on Sei, paying only about one-tenth of Uniswap’s fees. The CLOB design also raises execution quality. Compared with AMMs, on-chain order matching lowers slippage, which is helpful for large trades. A time-priority rule reduces front-running and MEV risk. Average order execution can be as low as 0.3 seconds, giving a near-CEX experience.

A modular design is key to long-term strength. Clovis plans several DeFi modules, including lending, derivatives, stablecoin minting, and an NFT market. It targets different user groups. For example, the lending module will support multi-chain collateral. Users could collateralize SOL from Solana on Clovis and borrow USDC on Sei, enabling efficient cross-chain capital use. The modular architecture also brings strong extensibility.

By late 2025, Clovis plans to support Layer-2 networks like Arbitrum and Optimism, expanding coverage. To attract developers, Clovis will offer an SDK and APIs so third parties can build custom dApps, similar to Ethereum’s ecosystem model. This openness can draw more projects into Clovis and strengthen network effects.

The vision is ambitious, but cross-chain integration is hard. Real-time syncing of multi-chain assets needs complex bridge protocols. This can add latency and security risks. Clovis will also face competition from mature cross-chain stacks like LayerZero and Axelar. It must win on user experience and cost. Cross-chain DeFi is complex for newcomers. Clovis needs simple UX and education to lower the learning curve. Even so, with Sei’s high performance and Yei Finance’s user base, Clovis could become an important player in cross-chain DeFi.

CONCLUSION

Through its mature money market, Yei Finance set a solid DeFi base on Sei. It uses Sei’s high-performance design to give users low-cost, efficient lending and trading. The launch of Clovis marks Yei Labs’ shift toward a cross-chain DeFi operating system. By unifying liquidity, improving order matching, and using a modular design, it tries to solve the fragmentation of the multi-chain world. Sei’s forward-looking DeFi strategy is worth watching in the future.
