Sentiment is a decentralized lending and borrowing protocol built on the HyperEVM, the Ethereum-compatible layer of the Hyperliquid blockchain. It focuses on enabling users to deposit assets to earn yield or borrow assets to create leveraged positions—all in a non-custodial, permissionless environment.
Launched on HyperEVM mainnet in March 2025, Sentiment is designed to maximize capital efficiency within the DeFi ecosystem while providing adaptive risk management and robust security. Supported collateral includes assets like $HYPE, Hyperliquid’s native token, and wstHYPE, its staked derivative.

What Is Sentiment?
At its core, Sentiment is a DeFi lending and leverage protocol tailored for the Hyperliquid ecosystem. Unlike traditional perpetuals offered directly on Hyperliquid, Sentiment allows users to access higher leverage and more flexible strategies through smart contract-based lending pools.
Each pool is isolated, meaning risks are contained within that pool and do not spill over to the rest of the system. This makes it possible to design customized pools with unique parameters and tailored risk models.
By leveraging the HyperEVM, Sentiment benefits from:
- Low-latency, high-performance transactions.
- Native $HYPE gas token integration.
- Composability with Hyperliquid’s perpetuals and spot markets.
How the Protocol Works
Sentiment operates through modular smart contracts, allowing scalability and future upgrades without compromising security.
1. Architecture and Core Components
- Accounting Module: Tracks balances, yields, and leveraged positions.
- Deposit Module: Handles asset deposits into isolated pools.
- Borrow & Repay Module: Controls loans, repayments, and liquidations.
This modular structure makes the protocol more flexible and adaptable to evolving market conditions.
2. Isolated Lending Pools
Each pool is independent and supports specific assets or strategies. Risks from one pool cannot cascade into others. Pools can be created permissionlessly, enabling experimentation and decentralized innovation.
3. Adaptive Risk Management
- Loan-to-Value (LTV) ratios are dynamic and adjust based on market conditions.
- Risk assessments are automated, with integrations like EZKL for real-time monitoring.
- Particularly useful in volatile markets, such as those seen in the Hyperliquid ecosystem.
4. Lending and Borrowing Mechanics
- Lending: Users deposit assets (e.g., $HYPE, USDe, USDT0) into pools to provide liquidity and earn interest.
- Borrowing: Borrowers supply collateral and take out loans to increase their exposure (up to 5x or more, depending on the pool).
- Repayment & Liquidation: Borrowers repay loans with interest, and positions below collateral thresholds are liquidated automatically.
5. Leverage Strategies
Sentiment enables flexible strategies such as leveraged long and short trades, yield farming with borrowed assets, and custom risk-adjusted pools.

Advanced Features
- Permissionless Pool Creation: Anyone can launch new pools with customized collateral and parameters.
- Security and Audits: Sentiment has undergone multiple security audits and strengthened protections after past incidents.
- Cross-chain Integrations: Expanding usability through bridges like LayerZero.
- Hyperliquid Ecosystem Benefits: Backed by Hyperliquid’s large TVL and active user base, exceeding $4.3B in open interest in some reports.
Past Hack Incident
In April 2023, while operating primarily on Arbitrum, Sentiment suffered a reentrancy exploit that drained approximately $1 million in assets.
- The attacker exploited vulnerabilities in price manipulation.
- Following negotiations, the hacker returned ~90% of the funds, and the Sentiment team rewarded them with a $95,000 bounty.
- All affected users were reimbursed in full.
Since then:
- No major hacks have been reported.
- The HyperEVM version (launched in March 2025) has operated securely.
- Post-incident audits and architectural improvements were implemented to strengthen protocol safety.
How to Farm the Sentiment Airdrop
Sentiment offers a simple interface for lending and borrowing, making it accessible to both advanced users and newcomers.
- Lend: Deposit assets such as HYPE, USDe, or USDT0 into isolated pools to earn yield.
- Borrow: Supply collateral (like $HYPE or wstHYPE) to unlock leverage. The Leverage function allows borrowers to expand exposure with assets like kHYPE and wstHYPE.
- Airdrop Incentives: By participating in the protocol, users may qualify for airdrops and incentive programs designed to reward early adopters.
This dual approach (earning passive yield as a lender or taking on leverage as a borrower) ensures that both risk-averse and risk-seeking participants can engage meaningfully.
Final Thoughts
Sentiment has been steadily growing, surpassing $35M in TVL. Despite its history of a hack during its early Arbitrum days, the protocol has recovered, strengthened its security, and established itself within the HyperEVM ecosystem.
While its relatively modest TVL compared to larger competitors may present some risk, this also means less diluted farming opportunities for those willing to interact early.
For airdrop hunters and DeFi participants looking to diversify their exposure within Hyperliquid’s HyperEVM, Sentiment represents a compelling, though somewhat higher-risk, protocol to watch and interact with.
