The ratio of collateral of 300% is used to backed the each synthetic invested. For instance a user locks 3USD worth of BYN token to invest 1 USDb in the share pool. 300% C-Ratio needs to be met to be eligible for staking reward. In order to reduce the burden to manually adjust the C-Ratio every time, Beyondfi platform provides an advanced auto-staking system where additional BYN amount to meet 300% ratio is automatically calculated and automatically staked from the system if user holds any unstaked BYN in Beyondfi Wallet as a buffer. On the other hand, in case of C-Ratio increases to over 300%, the excessive amount of staked BYN is automatically unstaked from the system.
