**Change 1: Change crvUSD IRM parameters**

Reason: We propose slight changes to slow APR growth/decrease when utilization is outside the optimal region to give borrowers ample time to adjust positions without paying excessive rates. The change will help retain borrowers.

**Suggested change**

```auto
stableHighCapV3: {

uopt: 800000000000000000n,

ucrit: 900000000000000000n,

ulow: 600000000000000000n,

ki: 110103,

kcrit: 237823439878,

klow: 26424826653,

klin: 3170979198,

beta: 11574074074074,

ri: 0,

Tcrit: 0,

},

```

**What does the change do?**

- It slows APR growth when utilization is outside the optimal region (above 80%.)

- It slows down the APR decrease when utilization goes down from a point above optimal to a point below.

**Comparison**

**Change 2: Change CRV IRM parameters**

Reason: The Change moves the max opt point (uopt) to 65%, effectively resulting in stable APRs when utilization (U) is in the region 1% to 65% rather than 1% to 50%. The change will help increase borrows for CRV and retain current borrowers.

**Suggested change**

```auto
volatileOpt65Base9p1: {

uopt: 650000000000000000n,

ucrit: 900000000000000000n,

ulow: 300000000000000000n,

ki: 146805,

kcrit: 317097919838,

klow: 105699306613,

klin: 4439370878,

beta: 69444444444444,

ri: 0,

Tcrit: 0,

},

```

**What does the change do?**

- APRs start growing when utilization is above 65% rather than 50%, which is in effect today.

- APRs start declining when utilization moves down from a point above 65% to a point below.

In the event we hear no objection, we will move to execution. As always, we will share unexecuted transactions with the community for transparency and execute within 24-48 hours of posting the transactions publicly.

**Change 3: Update crvUSD price provider**  
The new price provider (oracle) reads the price of crvUSD from the Curve [crvUSD-USDC pool](https://etherscan.io/address/0x4DEcE678ceceb27446b35C672dC7d61F30bAD69E) instead of [crvUSD-USDT](https://etherscan.io/address/0x390f3595bCa2Df7d23783dFd126427CCeb997BF4) pool.

- Old price provider: [CrvUSDViaUSDCPriceProviderETH | Address 0xa1c2837b7A899d6f89282e9bE9f1496D12e86bBa | Etherscan](https://etherscan.io/address/0xa1c2837b7A899d6f89282e9bE9f1496D12e86bBa#code)
- New price provider: [CrvUSDViaUSDCPriceProviderETHV2 | Address 0x1781452eD27BbA7fA8932b2D839F244FaCd23a27 | Etherscan](https://etherscan.io/address/0x1781452eD27BbA7fA8932b2D839F244FaCd23a27#code)

Execution:  
Queuing transaction to affect change 1 and 3. The tx will be executed by Feb. 23, 2024.
