APEX: AI-Algorithmic-Stablecoin-to-Foreign-Currency Exchange Protocol (Part 2)

Smart Stake Percentage Adjustment

Generally speaking, stablecoins on APEX go through two cycles: the inflationary cycle and the deflationary cycle. In an inflationary cycle, APEX will reduce the percentage of stakes but raise the percentage of AX required to mint an algorithmic stablecoin. While in a deflationary cycle, APEX will raise the percentage of stakes, and people redeeming their AX will get more AX and fewer stakes.

The functions contained in stablecoin contracts will calculate and update the smart adjustment process on an hourly basis, and the percentage of stakes will be adjusted by 0.25% each time. Take AUSD for example.When its price is higher than $1, the percentage of stakes will be adjusted down 0.25% for each passing hour; and when its price is higher than $1, the stake percentage will go up by 0.25% every hour. If the price of AUSD should stay under $1 for a long time, the percentage of stakes will gradually move close to 100%.


Every type of algorithmic stablecoins has its independent contract and staking pool on APEX. Stablecoins of the same type are interchangeable and have an identical stake percentage regardless of what percentage they had at the time of minting.

​APEX’s functions for minting are as follows.

​Take AUSD for example. If we have C=97%, then to mint an AUSD requires $0.97 worth of stakes and burns $0.03 worth of AX.

Note that on APEX minting algorithmic stablecoins costs a minting fee, which is charged in AX at 0.2% of the total value of the minted stablecoins.


The functions for redemption are as below.

Note that on APEX redeeming algorithmic stablecoins costs a fee, which is charged in AX at 0.45% of the total value redeemed.
