Note — For users who staked both PERI and Stablecoin(USDC, DAI)
If users who staked PERI and other kinds of stablecoin, you should maintain the staking ratio(PERI 80% : other stablecoin 20%)on the staking dApp.
So, if you unstake all PERI amount in the dApp, you should burn pUSD by the stablecoin first.
