</AccordionGroup>

## How It Works

Each currency operates as an independent market:

```
USD Market              EUR Market              JPY Market
────────────            ────────────            ────────────
USDC Lenders     ←→     EURC Lenders     ←→     JPYC Lenders
    ↕                       ↕                       ↕
USDC Borrowers          EURC Borrowers          JPYC Borrowers
    ↕                       ↕                       ↕
USD Rates               EUR Rates               JPY Rates
(e.g., 8%)              (e.g., 6%)              (e.g., 3%)
```

### Independent Rate Discovery

Each currency market has its own supply/demand dynamics:

* USD markets may offer 8% APY
* EUR markets may offer 6% APY
* JPY markets may offer 3% APY

Rates reflect each currency's market conditions, not arbitrary conversions from USD.

## Cross-Currency Collateral

<Info>
  **Borrow in any currency using collateral in any currency.** Centuari supports cross-currency collateralization.
</Info>

| Scenario       | Collateral | Borrow | Supported |
| -------------- | ---------- | ------ | --------- |
| Standard       | USDC       | USDC   | ✅         |
| Cross-currency | USDC       | EURC   | ✅         |
| Cross-currency | ETH        | JPYC   | ✅         |
| Cross-currency | EURC       | USDC   | ✅         |

### FX Risk Considerations

<Warning>
  Cross-currency borrowing introduces FX risk. If your collateral currency weakens against your borrow currency, your health factor decreases.
</Warning>

**Example**:

* Deposit: \$10,000 USDC as collateral
* Borrow: €8,000 EURC
* If EUR strengthens vs USD, your loan value in USD terms increases
* Health factor decreases

**Mitigation**:

* Maintain higher collateral ratios for cross-currency positions
* Match collateral and borrow currencies when possible
* Monitor FX movements

## Currency Abstraction

For users who don't want to think about currency:

Currency abstraction:

* Analyzes rates across all currency markets
* Suggests optimal currency for your goals
* Can auto-convert at entry/exit (with user permission)

## FAQs

<AccordionGroup>
  <Accordion title="Are rates the same across currencies?">
    No. Each currency market has independent rate discovery based on local supply and demand.
  </Accordion>

  <Accordion title="Can I convert between currencies within Centuari?">
    Currency conversion is available through integrated DEX routing. Protocol doesn't hold conversion reserves.
  </Accordion>

  <Accordion title="What about stablecoin depeg risk?">
    Each stablecoin has its own risk profile. The protocol monitors peg stability and can pause markets if significant depeg occurs.
  </Accordion>

  <Accordion title="How are cross-currency collateral ratios determined?">
    Cross-currency positions require higher collateral ratios (typically +10-20%) to account for FX volatility.
  </Accordion>
</AccordionGroup>

<Info>
  Centuari will support more local and global stablecoins over time to fulfill our vision of accessible fixed-rate lending worldwide.
