STAKING PERI

Staking: Open a Position

As the prices of underlying pynths fluctuate with oracle updates, the size of the debt pool fluctuates too, It means that staker's debt independent from the amount of pUSD that was issued.
To consider the risk stakers take on by being exposed to a shared debt pool, they are rewarded each week in the form of pUSD trading fees and PERI inflationary rewards .
