Bonuses would drain the redemption position over time, requiring constant recapitalization. Strict 1:1 keeps the position neutral and sustainable indefinitely. + +**Q: How does this maintain the peg without bonuses?** +A: Pure arbitrage. If MOET < $1, users profit by buying and redeeming. If MOET > $1, users profit by minting and selling. Market forces naturally push price to $1.00. + +**Q: What happens if the redemption position gets liquidated?** +A: Redemptions are blocked if position health < 1.0. Admins should monitor health and top up collateral proactively. + +**Q: Can I redeem any amount of MOET?** +A: Min 10 MOET, max 10,000 MOET per transaction, up to 100,000 MOET per day. + +**Q: Do I always get exactly $1 per MOET?** +A: Yes, always. 100 MOET = $100 worth of collateral at oracle prices, regardless of position health. + +**Q: How long do I have to wait between redemptions?** +A: 60 seconds (configurable by governance). + +**Q: What if my preferred collateral type isn't available?** +A: The contract automatically falls back to the pool's default token (typically Flow). + +**Q: Who pays for the redemption mechanism?** +A: No one!
