$NOTE is a fully immutable ERC-20 token backed by collateral lent to the CLM. It can can only be borrowed by users who post select collateral assets such as $USDC, $USDT, $CANTO, $ETH, $ATOM, or Canto LP tokens.
As a result, for every $NOTE in circulation, there is more than 1 USD worth of collateral held by the CLM.
Capital efficiency
Canto Lending Market achieves superior capital efficiency by allowing stablecoin collateral backing $NOTE to be lent out to other participants. For example, a DeFi participant can lend $USDC to Canto Lending Market and then borrow $NOTE. If the borrow rate for $NOTE is less than the supply rate for $USDC, that DeFi participant will be getting paid to hold $NOTE on Canto.
Important: Canto Lending Market will launch with conservative parameters. Over time, the Canto DAO will be able to raise the capital efficiency of CLM to its full potential.
Maintaining $NOTE Price Stability
Since $NOTE cannot be created, only borrowed, the Accountant contract utilizes interest rates to manage the circulating supply of $NOTE, and by proxy, its price. The interest rate on $NOTE automatically adjusts up or down every 6 hours based on a TWAP of the market price of $NOTE.
Aiming to provide a public utility, the algorithm responsible for adjusting this interest rate is designed to change the interest rate in order to promote a less volatile value as opposed to maximizing revenue.
If $NOTE is trading under $1, the interest rate is raised to strengthen the incentive for buying $NOTE on secondary markets and lending it to the CLM. If $NOTE is trading over a dollar, the interest rate is lowered to make borrowing $NOTE from the CLM and selling it on secondary markets more attractive.
For launch, each interest epoch will be 6 hours and the rate will adjust by 0.25 (one-quarter) of the difference between the price of $NOTE and $1.00.
The Formula:
newInterestRate = max(0,(1 - price of $NOTE)*Adjuster Coefficient+ priorInterestRate)
Example:
Current Interest Rate: 4%. $NOTE average price over the last 6 hours: 1.04.
New Interest Rate: 3% = max (0, (1 - 1.04)* 0.25 + 4%)
If $NOTE is trading above $1, the interest rate is lowered to weaken the $NOTE price. If $NOTE is trading below $1, the interest rate is raised to strengthen the $NOTE price.
