Overview
https://kanpeki.finance
Kanpeki is an incentivized, non-custodial, individualized, fixed-rate borrowing and lending platform.
While there are many lending platforms today, there is an important difference in Kanpeki: all interest rates are fixed, unchanging, user chosen — i.e. not set by any algorithm — and not annualized. There is no concept of "apy" or "apr".
Depositors — i.e. lenders — deposit their tokens into one or more vaults after choosing a fixed interest rate they want. Dependent on the activity in the vault they deposited, they will eventually be able to withdraw, or redeposit, exactly this percent rate of interest. The more active the vault, the faster the interest is earned.
On the other side, borrowers borrow from these vaults for a fixed duration at a fixed interest of their choosing. The interest is always paid in full regardless of when it is repaid. However, for every debt a borrower repays, the borrower is eligible to mint an amount of Kanpeki (KAE) tokens proportional to the value of their repaid debt and interest rate on it. Simply, the higher the interest rate and duration, the higher the KAE reward, even exceeding the value of the interest paid if choosing higher interest rates and durations.
How are rates fixed?
Kanpeki is not a "money-market" — interest rates aren't determined by some algorithm acting on the interplay of borrowers and depositors altering the balance of a contract. Rather, individual borrowers and depositors choose their exact interest rates.
Example
If SpongeBob deposits some tokens and for 3% interest, this will remain exactly 3% even if 30 minutes later, Krabs and Plankton deposit 10x more tokens at 4% and 5% respectively. Deposits by other users have no effect on the chosen interest rates of other users.
Similarly, if Squidward borrows some tokens at 2.5%, it'll remain exactly 2.5% even if 30 minutes later, Krabs and Plankton borrow 10x more tokens at 2% and 4% respectively. As with deposits, borrows by other users have no effect on the chosen interest rates of any other user.
The rates that can be chosen by depositors are not affected by the rates chosen by borrowers, and vice-versa
In this sense, Kanpeki is "individualized". That means, regardless of what another party in the system chooses to do — depositing, withdrawing, borrowing, or repaying some amount at some % interest — it has no effect on what you have chosen for yourself.
What does "not apr/apy" mean?
Most defi borrowing/lending platforms operate with an "apy"/"apr" interest rate model — conditions "now" extrapolated 365 days into the future. Aside from taking for granted the inherent volatility profile of cryptocurrencies, the extrapolated earning/rate is guaranteed to always be misleading.
Kanpeki's rates are fixed, actually fixed. The interest due based on a depositor's chosen interest rate when depositing is the interest the depositor will eventually earn from their deposit. And the interest due on a borrower's debt remains unchanged regardless of how many more people choose to borrow or when the borrower chooses to repay.
Where does the KAE reward for borrowers come from?
KAE is a standard ERC20 token with minting and burning functionality. There is no supply cap, essentially making it a dynamic supply token.
With regards to burning, 100% of the fees charged by the platform are used to periodically buy-back and burn the token (as well provide liquidity for it in relevant markets). And for minting, borrowers that repay their debts are able to mint KAE tokens.
Only claimed rewards add to the KAE supply. If the reward for some debt is never claimed, it doesn't exist and doesn't affect the supply
What about inflation?
First off, Kanpeki doesn't strive to make KAE deflationary.
While it's fashionable to attack inflation as some sort of "malfeature", especially in dapp projects, this stance misunderstands how inflation can be useful in aligning incentives for dapps, much like in networks like Ethereum and the like where it's used to incentivize validation.
Inflation of any sort in Kanpeki doesn't happen in a vacuum but if, and only if, a borrower repays and claims the reward for repayment. As such, meaningful inflation necessarily presupposes:
- a significant amount of not merely borrowers, but borrowers paying interest
- a significant amount of depositors seeking these high interests as borrowers are, after all, borrowing deposited tokens
- a scale of borrowing and, especially, depositing that requires the participants to be staking and seeking to acquire more KAE in order to maintain their stakes that provide access to higher interest rates and rewards (as staking in Kanpeki is dynamic, not static)
But if the above is happening, depositors would necessarily be acquiring the new "inflation" generated by these borrowers in order to stake, thus reducing the active, circulating supply.
In addition, the inflation that can happen is limited by the reward cap, which is reduced as the price of KAE moves away from $1, and that can be assumed to happen since in this "high inflation" scenario, demand for staking would be higher than the inflation (since KAE is only claimed when a debt is repaid, rather than at the start thus causing it to lag behind). As this cap reduces, it would require even more borrowers to come in in order to merely keep the inflation constant, starting the process all over again.
Can I simultaneously borrow and deposit?
Yes.
You can deposit tokens into a vault while simultaneously borrowing from it. This is merely one way to earn KAE that can be used for staking to retain access to certain perks in the system.
Depositing is not equivalent to "supplying" in other platforms. Depositing and borrowing are separate actions. Your deposit cannot be used as collateral when trying to borrow
