What is the Insurance Pool?

The USDT Insurance Pool backs all USD bond series. It protects Note holders when series proceeds aren't enough to repay principal.

The Simple Explanation

USD Bond Note holders need repayment

                ▼
     Series proceeds (BTC → USDT)
                │
                ▼
┌───────────────────────────────────┐
│   Enough to repay everyone?       │
└───────────────────────────────────┘
        │                   │
       YES                  NO

    Done ✓           Insurance Pool
                     covers the gap

The pool exists so USD bond investors don't depend solely on BTC price at maturity.

Who Funds the Pool?

USDT stakers. Anyone can stake USDT into the pool and earn Warrant NFT rewards.

Stakers are taking on risk (their USDT may be used to cover shortfalls) in exchange for rewards.

How Stakers Are Protected

If the pool covers a shortfall, stakers don't just lose their USDT:

1. Pre-minted $MSTR is reserved at each USD bond issuance

2. If a shortfall occurs, stakers receive $MSTR to compensate for the USDT used

3. $MSTR value is calculated using 24-hour TWAP (fair, manipulation-resistant)

4. Any leftover pre-minted $MSTR is burnt

When Does the Pool Take a Loss?

Only in an extreme scenario:

This is the risk stakers accept in exchange for Warrant rewards.
