Summary
In preparation for Notional’s upcoming quarterly roll occurring Sunday, June 26th at 8:00 PM EST we propose to update some of the protocol’s governance parameters in order to increase capital efficiency across Notional pools. These changes would lead to lower slippage for borrowers and lenders and lower settlement fees for borrowers.
AMM curves
Objective : Enable more capital-efficient AMM curves with more restricted interest rate ranges.
More specifically, we propose to change the stablecoin interest rate ranges from 0%-20% to 0%-15%, change the ETH interest rate range from 0%-15% to 0%-12%, and change the WBTC interest rate range from 0%-15% to 0%-10%.
In order to do so, we propose to lower anchor rates thus shifting the curves down in the X-Y plane. In addition, we propose to increase scalar rates to flatten the AMM curves.
- ETH : Increase scalar rates from 32 to 39
- DAI : Decrease anchor rates from 2% to 1% (3M), 2% to 1% (6M), and 4% to 1% (1Y), and increase scalar rates from 26 to 33 (3M), 26 to 33 (6M), and 26 to 31 (1Y).
- USDC : Decrease anchor rates from 2% to 1% (3M), 2% to 1% (6M), and 4% to 1% (1Y), and increase scalar rates from 26 to 33 (3M), 26 to 33 (6M), and 26 to 31 (1Y).
- WBTC : Decrease anchor rates from 1.0% to 0.5% and increase scalar rates from 32 to 46.
Deposit shares
Objective : Allocate more capital to the pools with higher lending/borrowing demand. We have historically seen more market demand for the 3 Month stablecoin maturities. Therefore we propose to allocate slightly more liquidity to the 3 Month pools.
- DAI : Change the deposit shares from 40% (3 Month), 40% (6 Month), and 20% (1 Year) to 45% (3 Month), 40% (6 Month), and 15% (1 Year).
- USDC : Change the deposit shares from 40% (3 Month), 40% (6 Month), and 20% (1 Year) to 45% (3 Month), 40% (6 Month), and 15% (1 Year).
Initial proportions
Objective : Initialize new 6-month markets at proportions in line with current variable rates.
- ETH : Initialize the 6-month market at a proportion of 0.45 (0.5% interest rate)
- WBTC : Initialize the 6-month market at a proportion of 0.50 (0.5% 0.5% interest rate)
Settlement penalty rates
Objective : Lower the penalty rates paid by delinquent borrowers upon quarterly rolls.
All currencies : Decrease the settlement penalty rate from 50 (2.5%) to 40 (2.0%).
Leverage thresholds
Objective: Update leverage thresholds to ~8% for USDC and DAI, ~6% for ETH, and ~4% for WBTC. If rates are above these levels any incoming liquidity will be lent. Leverage thresholds also aim to ensure that nToken accounts never become undercollateralized by providing liquidity to individual liquidity pools at leverage ratios that are too high.
- ETH: Set the leverage thresholds to 0.88 (3M) and 0.88 (6M)
- DAI: Set the leverage thresholds to 0.88 (3M), 0.88 (6M), 0.87 (1Y)
- USDC: Set the leverage thresholds to 0.88 (3M), 0.88 (6M), 0.87 (1Y)
- WBTC: Set the leverage thresholds to 0.84 (3M) and 0.84 (6M)
