Yes — and this is important to understand before depositing. HLP is a market-making vault that takes active trading positions. If those positions lose money in a given period, the vault’s NAV drops and depositors’ USDC balance decreases. In early 2025, Hyperliquid absorbed a $12M bad debt event from a large position that was liquidated — the platform covered this from the HLP Insurance Fund rather than passing it to depositors, but it demonstrates that tail risks exist. Historically across 2024–2026 HLP has been significantly profitable, but past performance does not guarantee future results. Only deposit what you can afford to hold through a drawdown period.

In most jurisdictions, yield earned on DeFi lending platforms like Aave is treated as ordinary income for tax purposes — the same as interest from a savings account. Similarly, HLP distributions are generally taxable as income when received. Tax treatment varies by country and situation, so consult a tax professional familiar with crypto. Both platforms generate on-chain transaction records that make tax reporting possible — tools like Koinly, TokenTax, and CoinTracker can import your wallet history and generate reports.

Yes — and many experienced DeFi users do. A common allocation strategy: put 50–70% of idle USDC into HLP for the higher yield, and keep 30–50% in Aave on Base or Ethereum for instant liquidity and a lower-risk base yield. This gives you a blended rate — say 12–15% on the combined portfolio — while keeping a portion always accessible without a lockup. The two platforms don’t interact with each other, so running them in parallel is straightforward. Just remember the 4-day HLP unlock when you’re planning your liquidity needs.
