How it works
1. Deposit
Deposit any supported asset into Hubra Earn. Your funds immediately start generating yield.2. Track your balance
In the Hubra app, you’ll see your original asset (USDC, SOL, etc.) in the tokens tab — not a new token symbol. Tap on the asset to see:- Idle balance - funds sitting in your wallet
- Earning balance - funds actively generating yield
- Current APY - the rate you’re earning right now
3. Yield accrues automatically
Behind the scenes, Hubra uses an exchange-rate model. Your earning balance appreciates over time as yield compounds — no claiming or reinvesting needed.4. Withdraw anytime
Pull out whenever you want. No lockups, no cooldowns. You get your original deposit plus all accumulated yield.What happens behind the scenes
Hubra doesn’t just park your funds in one place. The system actively optimizes where your assets are deployed.The exchange-rate model
Under the hood, your earning balance is represented by ra tokens (raUSDC, raSOL, etc.). These tokens appreciate in value as yield accrues. Example: You deposit 100 USDC. Over time, as yield accumulates, that position might be worth 104 USDC - even though you never claimed anything. You don’t see ra tokens in the Hubra app — we show you the actual dollar value. But the math works the same as Aave’s aTokens or Compound’s cTokens.Fully automated & permissionless
The rebalancer runs autonomously. No manual intervention, no human operators deciding where funds go. Open source: The rebalancer code is public. You can audit the logic, verify how decisions are made, and see exactly what runs under the hood.Rebalancer

Security & Risk
Hubra Earn is built on top of Ranger Finance — an institutional-grade vault infrastructure designed for professional asset managers and hedge funds.Non-custodial architecture
Ranger vaults operate on a non-custodial basis. For fully on-chain strategies, neither Hubra nor Ranger can withdraw user deposits. Strategy execution is restricted to whitelisted protocols and functions, ensuring your funds remain under programmatic control at all times.Audited smart contracts
Ranger’s vault infrastructure has undergone multiple professional security audits:| Component | Auditor | Status |
|---|---|---|
| Vault Program | Sec3 X-RAY | ✅ Passed |
| Adapter Programs | Sec3 X-RAY | ✅ Passed |
| Vault Program | FYEO | ✅ Passed |
Whitelisted protocol integrations
Funds can only interact with pre-approved, audited protocols through Ranger’s adapter system:- Lending: Kamino, Drift, Jupiter
Transparency
All vault positions and protocol interactions are visible on-chain. You can verify exactly how yield is generated and assess the protocols involved at any time.Ranger Finance Documentation

Understanding the risks
While Hubra employs institutional-grade infrastructure and only allocates to audited protocols, DeFi carries inherent risks:- Smart contract risk - vulnerabilities in underlying protocols
- Protocol risk - potential failures in integrated DeFi platforms
- Market risk - fluctuations in asset values and yields
Supported assets
Stablecoins
Stablecoin strategies use automated lending across Kamino, Drift, and Jupiter:- USDC
- USDT
- USDS
- USDG
- USD1
External Wallet Users
If you connect an external wallet (Phantom, Backpack, etc.) and deposit into Earn, you may see a token calledraXXXX (e.g., raUSDC, raSOL) appear in your wallet app.
In the Hubra app, you won’t see these ra tokens - we display your actual asset balance instead.
Withdrawals
You can withdraw anytime. No lockups, no cooldowns, no unstaking delays. When you withdraw:- Your earning position is closed
- You receive the underlying asset at the current value
- The amount includes your original deposit plus all accumulated yield
