Risk management and user protection is a core focus at Helio Protocol, and thus, multiple risk management procedures are in place. Firstly, a LTV ratio of 66% is used to ensure that there is sufficient over-collateralization of BNB to tide over a black swan event. The LTV ratio of 66% is also referenced from what is used at MakerDAO, which suggests that it is an optimal, battle-tested LTV ratio.
Secondly, users can opt to subscribe to Helio’s personalized Liquidation Alert System (LAS), which allows users to be notified via telegram when the liquidation threshold is approaching, allowing them sufficient time to react accordingly. Users who subscribe will also be notified when the collateral price is experiencing abnormal levels of volatility, and is approaching liquidation price.
Lastly, Helio Protocol has employed an emergency shutdown mechanism that is smart-contract regulated, and will be triggered in the event of a “black swan” event. The shutdown process will be used as a last resort to prevent attackers from attacking Helio Protocol’s blockchain infrastructure.
