From cc7c5df6e6db738efb71dde67f9d40f6e306fa8e Mon Sep 17 00:00:00 2001 From: kgrgpg Date: Tue, 4 Nov 2025 13:47:39 +0100 Subject: [PATCH 01/15] feat: Implement sustainable MOET redemption mechanism (1:1 parity) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add RedemptionWrapper contract for MOET stablecoin redemption with strict 1:1 oracle price parity. This implementation ensures economic sustainability by maintaining position neutrality - no value drain on the redemption position. **Key Features:** - Strict 1:1 redemption (1 MOET = $1 of collateral at oracle prices) - Sustainable economics (debt reduction = collateral value withdrawn) - MEV protection (per-user cooldowns, daily limits, oracle staleness checks) - Reentrancy guards and comprehensive security features - Position solvency validation (pre and post redemption) - Emergency pause mechanism **Economic Model:** - Removed bonuses/haircuts from previous design (were unsustainable) - Pure arbitrage-based peg maintenance - Position stays neutral indefinitely - No recapitalization needed **Contract:** cadence/contracts/RedemptionWrapper.cdc (419 lines) **Documentation:** REDEMPTION_GUIDE.md (590 lines, comprehensive) **Security:** - Reentrancy protection ✅ - Daily circuit breaker (100k MOET default) ✅ - Per-user cooldowns (60s default) ✅ - Oracle staleness tracking ✅ - Position ID tracking ✅ - Postcondition health validation ✅ **Testing:** Ready for testnet deployment with conservative defaults **Audit Status:** Requires professional security audit before mainnet --- REDEMPTION_GUIDE.md | 589 ++++++++++++++++++++++++ cadence/contracts/RedemptionWrapper.cdc | 418 +++++++++++++++++ 2 files changed, 1007 insertions(+) create mode 100644 REDEMPTION_GUIDE.md create mode 100644 cadence/contracts/RedemptionWrapper.cdc diff --git a/REDEMPTION_GUIDE.md b/REDEMPTION_GUIDE.md new file mode 100644 index 00000000..e3ae2d49 --- /dev/null +++ b/REDEMPTION_GUIDE.md @@ -0,0 +1,589 @@ +# MOET Redemption System - Production Guide + +**Contract:** `cadence/contracts/RedemptionWrapper.cdc` +**Version:** 2.1 +**Status:** Ready for Testnet Deployment +**Last Updated:** November 4, 2025 + +--- + +## Overview + +The RedemptionWrapper contract enables users to redeem MOET stablecoin for underlying collateral at **strict 1:1 oracle prices**.

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! The position is economically neutral - debt reduction equals collateral value withdrawn. + +**Q: Is this audited?** +A: Testnet phase currently underway.

This is a common practice when: - -1. The actual values are consistent and deterministic -2. The differences are extremely small (less than 0.00001) -3. The theoretical calculations don't perfectly match implementation due to: - - Order of operations - - UFix64 precision limitations - - Rounding differences - -## Impact - -This change effectively gave Scenario 2 "perfect precision" by updating the test to expect what the system actually produces, rather than trying to make the system produce theoretical values. - -## Conclusion - -Alex Ni made a practical engineering decision to update the test expectations to match the consistent, deterministic output of the system. This is why Scenario 2 shows "perfect precision" after merging main - not because the calculations improved, but because the expected values were updated to match reality. \ No newline at end of file diff --git a/test_updates_final_summary.md b/test_updates_final_summary.md deleted file mode 100644 index 42755b7e..00000000 --- a/test_updates_final_summary.md +++ /dev/null @@ -1,96 +0,0 @@ -# Test Updates Final Summary - -## Overview -All rebalance scenario tests have been updated to: -1.
