dApps must integrate [MUSD](https://mezo.org/feature/musd), the native collateralized stablecoin of the Mezo ecosystem.

### Integration Options

<AccordionGroup>
  <Accordion title="Payment Support" icon="credit-card">
    Support MUSD as a payment method for goods, services, or transactions within your dApp.

    ```solidity theme={null}
    // Example: Accept MUSD as payment
    IERC20 musd = IERC20(MUSD_ADDRESS);
    require(musd.transferFrom(msg.sender, address(this), amount), "Payment failed");
    ```
  </Accordion>

  <Accordion title="Liquidity Asset" icon="water">
    Use MUSD as a primary liquidity asset in trading pairs, liquidity pools, or lending markets.

    ```solidity theme={null}
    // Example: MUSD liquidity pool
    IUniswapV2Pair pair = IUniswapV2Pair(factory.createPair(tokenA, MUSD_ADDRESS));
    ```
  </Accordion>

  <Accordion title="Core Function Integration" icon="gears">
    Integrate MUSD within other core functions such as collateral, yield generation, or reward distribution.

    ```solidity theme={null}
    // Example: MUSD as collateral
    function depositCollateral(uint256 amount) external {
        IERC20(MUSD_ADDRESS).transferFrom(msg.sender, address(this), amount);
        collateral[msg.sender] += amount;
    }

## 2. Security Audit

The dApp must have completed a third-party security audit. The audit report must be submitted to the [Supernormal Foundation](https://www.supernormal.foundation/page).

### Audit Requirements

<Steps>
  <Step title="Select an Auditor">
    Choose a reputable third-party security auditing firm. Recommended auditors include:

    * Trail of Bits
    * OpenZeppelin
    * Consensys Diligence
    * Certik
    * Quantstamp
  </Step>

  <Step title="Complete the Audit">
    Work with the auditor to review your smart contracts and address any findings.

    <Note>
      Ensure all critical and high-severity findings are resolved before submission.
    </Note>
  </Step>

  <Step title="Submit Audit Report">
    Submit your completed audit report to the [Supernormal Foundation](https://www.supernormal.foundation/page).

    * Findings and severity levels
    * Remediation actions taken
    * Final audit conclusion
