These parameter updates are a continuation of Gauntlet's regular parameter recommendations, the latest being [AIP-39: Risk Parameter Updates for Aave V2 assets](https://app.aave.com/governance/39-QmXQMnHQMP6KmwkCG8MjBCjxxNEeaHszh9FgFZFASkqPS2). \n\n## Motivation \n\nThis set of parameter updates seeks to maintain the overall risk tolerance of the protocol while making risk trade-offs between specific assets. Volatility for non-stablecoin crypto assets remains high. As such, we focused on supporting protocol safety for our parameter changes in this cycle. \n\nAdjustments were also made for three liquidation bonus values. These assets (UNI, BAL, LINK) saw increases in liquidity and trading volume and a reduced liquidation recommended value as a result. As always, simulation recommended values seek to maintain capital efficiency and uphold borrow usage levels.\n\n## Specification\n\n| Parameter | Current Value | Recommended Value |\n| -------- | -------- | -------- |\n| REN Loan To Value     | 55%     | 50%     |\n| SNX Loan To Value     | 20%     | 30%     |\n| SNX Liquidation Threshold    | 45.0%     | 55.0%     |\n| DPI Loan To Value     | 60%     | 55%     |\n| UNI Loan To Value     | 60%     | 55%     |\n| UNI Liquidation Bonus    | 10.0%     | 8.0%     |\n| YFI Loan To Value     | 45%     | 50%     |\n| BAL Liquidation Bonus    | 10.0%     | 8.0%     |\n| LINK Liquidation Bonus     | 10.0%     | 7.5%     |\n| BAT Liquidation Threshold    | 75.0%     | 80.0%     |\n| ENJ Liquidation Threshold    | 60.0%     | 65.0%     |\n| MANA Liquidation Threshold    | 65.0%     | 75.0%     |\n| ZRX Liquidation Threshold    | 70.0%     | 75.0%     |\n\n\n\n## Implementation \n\nThe proposal sets the LTV, liquidation bonuses, and liquidation threshold ratios by calling `configureReserveAsCollateral` on the `LendingPoolConfigurator` contract at `0x311Bb771e4F8952E6Da169b425E7e92d6Ac45756`, using the address and parameters specific to each token.\n\nThe full list of parameter updates can be found in the [forum](https://governance.aave.com/t/arc-risk-parameter-updates-2021-10-7/5854/3).\n\n## Copyright\n\nCopyright and related rights waived via [CC0](https://creativecommons.org/publicdomain/zero/1.0/).\n\n"}
