How It Works
Purinta is powered by Morpho — one of the most audited and battle-tested DeFi lending protocols. From your perspective as a user, this infrastructure is invisible. From a trust perspective, it means Purinta is built on a solid, credible foundation with no additional smart contract risk.
Morpho Blue
Morpho Blue is a trustless, efficient lending protocol that enables the creation of isolated lending markets, each defined by a specific collateral/loan token pair and risk parameters. Purinta uses Morpho Blue as its lending engine — all borrowing, collateral management, and liquidation logic runs on Morpho's audited smart contracts.
For the full technical details on Morpho Blue, see the Morpho documentation.
Markets
Each meme token on Purinta has its own independent lending market. A market is defined by three parameters:
| Parameter | Description |
|---|---|
| Supply asset | The meme token you supply as collateral (e.g. PEPE, SPX) |
| Borrow asset | Always USDC — simple and universal |
| LLTV | 62.5% — the maximum ratio of loan value to collateral value before liquidation |
Markets are fully independent. A position in one market has zero bearing on a position in another. This is important for users with diversified meme portfolios — a crash in one token does not affect your other positions.
LLTV (Liquidation Loan-to-Value)
LLTV stands for Liquidation Loan-to-Value. It defines the maximum ratio between your borrowed amount and collateral value. If this threshold is reached, your position gets liquidated.
Example: You supply $100 worth of PEPE. With an LLTV of 62.5%, you could theoretically borrow up to $62.50 USDC. However, Purinta's UI caps this at 95% of the maximum (~$59.37) to give you a built-in safety buffer. The UI also warns you when your borrow is close to the liquidation threshold.
For more on how liquidation works, see Risk & Liquidation.
Interest
Borrowers pay a variable borrow rate that accrues continuously. The rate adapts based on how much of the market's supply is being borrowed — when demand for borrowing is high, the rate increases; when it's low, the rate decreases. The current rate for each market is displayed as an APY in your position details. As interest accrues, you'll see your USDC borrow amount gradually increase over time.
The Purinta USDC Vault
Liquidity for borrowers comes from the Purinta USDC Vault, curated by Api3. It is built on top of Morpho's vault infrastructure and distributes USDC across all active meme token markets to ensure borrowers have access to liquidity.
On the supply side, lenders can supply USDC to the vault to earn yield from the interest paid by borrowers.
Oracles
Purinta uses Api3 dAPIs as its oracle infrastructure for price feeds. These oracles power real-time collateral valuations and liquidation triggers. A unique advantage of Api3's oracle system is OEV (Oracle Extractable Value) capture — value from liquidation events that would otherwise be lost to MEV bots is returned to the protocol, improving economics for all participants.
No Custom Smart Contracts
Purinta does not deploy any custom smart contracts. It is a frontend application that interacts directly with Morpho Blue's deployed and audited contracts. This means:
- No additional smart contract risk beyond Morpho itself
- Full transparency — all transactions are standard Morpho Blue operations
- Positions created through Purinta are compatible with any Morpho-compatible interface
