# Summary

We propose deploying Notional V3 on Mainnet with the following currencies.

- ETH
- DAI
- USDC
- WBTC
- wstETH
- FRAX
- rETH
- USDT
- cbETH
- sDAI

Each currency will support a variable rate market. Additionally, we propose that all these currencies support 3-month and 6-month fixed-rate markets, except for WBTC and sDAI, since they are primarily used as collateral currencies.

# Proposal

## Minimum Collateral ratios and liquidation discounts

| Currency | Haircut | Buffer | Liquidation discount | Minimum collateral ratio\* | Supply Cap |
| --- | --- | --- | --- | --- | --- |
| ETH | 87% | 120% | 5% | 125% | 25,000 |
| DAI | 92% | 109% | 4% | 118% | 25,000,000 |
| USDC | 92% | 109% | 4% | 118% | 50,000,000 |
| WBTC | 84% | 120% | 5% | 130% | 500 |
| wstETH | 83% | 120% | 6% | 131% | 10,000 |

The full list of governance parameters is presented in this [spreadsheet](https://docs.google.com/spreadsheets/d/1LQGlrZ1eonV-V3QqYHdDEoA5EQ7KHX9F4Dg_lcTLeh0/edit#gid=1038781883). Supply caps will be increased gradually by governors based on user demand up to the values specified in the table above.

| cbETH | 60% | 80% | 1.0% | 4.0% | 30% | 8% |

### 6 Month fixed rates markets

| Currency | Kink1 Utilization | Kink2 Utilization | Kink Rate 1 | Kink Rate 2 | Max Rate | Fee Rate |
| --- | --- | --- | --- | --- | --- | --- |
| ETH | 55% | 80% | 4.0% | 10.0% | 30% | 8% |
| DAI | 60% | 80% | 4.5% | 8.0% | 25% | 8% |
| USDC | 60% | 80% | 4.5% | 8.0% | 25% | 8% |
| wstETH | 60% | 80% | 1.0% | 4.0% | 25% | 8% |
| FRAX | 60% | 80% | 4.5% | 8.0% | 25% | 8% |
| rETH | 60% | 80% | 1.0% | 4.0% | 25% | 8% |
| USDT | 60% | 80% | 4.5% | 8.0% | 25% | 8% |
| cbETH | 60% | 80% | 1.0% | 4.0% | 25% | 8% |

We suggest allocating 60% of LP deposits to 3-month markets and 40% to 6-month markets. Alongside, we recommend initializing all fixed-rate markets at a utilization rate of 30%. This will initialize fixed rate markets at lower rates, facilitating borrowing from these markets. Furthermore, we propose setting leveraged thresholds at 84% across all markets.

We suggest setting the reserve fee share to 80% such that 80% of fixed rate trading fees will go to the protocol reserves while the remaining 20% of fees will be redistributed to liquidity providers.
