Bond and Buyback Fund
On extreme market conditions, it is possible that the insurance pool is unable to fully cover all cash-out applications, the so-called "risk spill".
Since the insurance pool experiences net inflow in the long-term, Derify protocol will securitize the spilled risk and turn it into bonds.
Rules are as follows:
- 1.If the redemption rate of the insurance pool is less than 100%, the system will issue bond token bToken to make up the redemption rate to 100%.
- 2.When the insurance pool overflows (insurance pool balance > system net loss), bToken holders can swap bToken (for e.g. bBUSD) for stablecoin at a fixed exchange rate of 1:1
- 3.The swapped bToken will be automatically burned
- 4.When there is no excess overflow of the insurance pool, the exchange of stablecoins will be suspended (first come first served)
- 5.Stake bonds can receive annual interest of%.
- 6.Interest are distributed periodically, in the form of more bToken tokens.
- 7.bToken can be freely traded on the market.
Because of the existence of annual interest, bToken fair price shall worth a little more than 1 USD per stable coin. As long as the interest rate
% is reasonable, the bond mechanism is safe and stable.
The interest rate
is also a changeable constant and can be adjusted via DAO community voting.
Bond is the final risk compensation mechanism for Derify protocol.
