Protocol Extensions

Moolah extends Morpho Blue with protocol-level controls designed for production risk management and product flexibility.

Minimum Loan Restriction (minLoan)

Each market can enforce a minimum borrow amount.

• Borrow transactions that result in debt below minLoan revert.

• Partial repay transactions that leave remaining debt below minLoan also revert.

This avoids dust positions that are expensive to liquidate and can increase bad-debt risk.

Reentrancy Protection

State-changing paths apply nonReentrant guards, including:

• supply()

• borrow()

• repay()

• withdrawCollateral()

• liquidate()

Upgradeability

Moolah is deployed as an upgradeable system.

• Upgrade authority is controlled by DEFAULT_ADMIN_ROLE.

• Execution is delayed by TimeLock.

• TimeLock provides a 1-day review window before upgrade takes effect.

Oracle Architecture

Moolah oracles expose a peek() interface with 8-decimal price scale (1e8).

Resilient Oracle

For resilient/multi-source oracle design, see:

• Multi-Oracle

PT Linear Discount Oracle

PT tokens use a linear discount model against underlying asset price before maturity.

• Typical use case: PT-based collateral markets such as PT-USDe / USD1

• Discount formula:

discount = baseDiscount x (timeToMaturity / totalDuration)

At maturity, discount goes to zero and oracle returns full underlying price.
