+title: Gauntlet Recommendation for MAI/MIMATIC deprecation, 2023.10.23
+author: Gauntlet
+discussions: https://governance.aave.com/t/arfc-gauntlet-recommendation-for-mai-mimatic-deprecation/15119
+---
+
+## Summary
+
+Given MAI/MIMATIC price drop to ~$0.72 and its inability to regain peg for the past few months, Gauntlet recommends to begin deprecation of MAI/MIMATIC. We aim to do so by reducing LT and increasing borrow rates to incentivize repayment.
+
+## Specification
+
+#### LT reductions
+
+| Chain | Asset | Current LT | Recommended LT |
+| ------------ | ----------- | ---------- | -------------- |
+| avalanche v3 | MAI/MIMATIC | 0.8 | 0 |
+| arbitrum v3 | MAI/MIMATIC | 0.8 | 0 |
+| polygon v3 | MAI/MIMATIC | 0.8 | 0 |
+| optimism v3 | MAI/MIMATIC | 0.8 | 0.65 |
+
+#### IR recommendations
+
+Adjust Uopt to 0.45, Slope 2 to 300%, RF to 95%
+
+| Chain | Asset | Current Uopt | Current Slope2 | Current RF | Recommended Uopt | Recommended Slope2 | Recommended RF |
+| ------------ | ------- | ------------ | -------------- | ---------- | ---------------- | ------------------ | -------------- |
+| arbitrum v3 | MAI | 0.8 | 0.75 | 0.2 | 0.45 | 3 | 0.95 |
+| avalanche v3 | MAI | 0.8 | 0.75 | 0.2 | 0.45 | 3 | 0.95 |
+| optimism v3 | MAI | 0.8 | 0.75 | 0.2 | 0.45 | 3 | 0.95 |
+| polygon v3 | miMATIC | 0.8 | 0.75 | 0.2 | 0.45 | 3 | 0.95 |
+
+## Implementation
+
+The proposal implements changes using the following payloads:
+
+- [Arbitrum](https://github.com/bgd-labs/aave-proposals/blob/main/src/AaveV3Update_20231024mai/AaveV3Arbitrum_20231024mai.sol)
+- [Optimism](https://github.com/bgd-labs/aave-proposals/blob/main/src/AaveV3Update_20231024mai/AaveV3Optimism_20231024mai.sol)
+- [Polygon](https://github.com/bgd-labs/aave-proposals/blob/main/src/AaveV3Update_20231024mai/AaveV3Polygon_20231024mai.sol)
+
+The changes on avalanche can be implemented using the following steward:
+
+- [Avalanche](https://github.com/bgd-labs/aave-proposals/blob/main/src/AaveV3Update_20231024mai/AaveV3Avalanche_20231024mai.sol)
+
