Why Helmet?

In traditional financial market , derivatives such as options has been shown as effective in hedging the risks of market volatility. But the market lack transparency and better infrastructure to improve efficiency. Considering that assets with high liquidity were eligible to be designed as options products, "The Options" became a unique tool to serve commodity traders.
With DeFi's infrastructure, anyone has right to price an asset on SWAP with unlimited liquidity. What makes us thinking is that if there's a tool or a platform where a crypto trader or holder could simply issue an advanced 'price based insurance' which could hedge price fluctuation and get rewards at the same time. Such things could help DeFi users and traders to reasonably evaluate their holding and risks.
We expect a picture that anyone in DeFi world, instead of centralized institutions, could create hedging tool for others at any time.
It's time to redefine"Option".


Helmet is a peer-to-peer insurance protocol written by option trading logic, which allows anyone to create any insurance policy easily in the market.
Unlike other insurance products you may have used, Helmet does not solve the problem of “Code Attack Risk” but allows DeFi users to be protected against the risk of price fluctuations., developed on BSC ( Binance Smart Chain), specialize in providing price-shield insurance for BSC assets. The types of insurance depends on token holders and traders.
Helmet offers insurance suppliers the right to "LOGO" modules by four elements——including insurance usage scenarios, type of insurance asset, insurance period, and insurance prices, allowing suppliers to flexibly assemble the types of insurance to sell and giving a variety of hedging strategies to the market.
In order to brief how to use the product, we have developed several insurance products as examples : "Cover 100% up" , "Cover 50% off ".
There are two roles in Helmet eco, Policy Supplier and Policy Holder. Supplier is the creator & seller of insurance policy. When they make the selling order to market, they could earn a little stable Helmet token reward. Holder is the buyer of insurance, and they could get the policy by paying to Supplier. When the policy mature, they could choose to claim or abstain the insurance based on the SWAP price. For example, Peter bought a 1 month of "Cover 50% off " insurance of A token, in this period, the price of A dump 50%, then Peter could claim it and earn a premium to hedge his lose.

Ryan who holds BNB, wants to participate in LPT(Liquidity provider Token)mining, but he worries about the HELMET dump. So he needs a hedging tool.
If 1 HELMET is equal to 4.5 BNB. He spends 0.1 BNB to buy a cover 50% off policy at 2.25 BNB on A week later, Ryan decides to stop mining and withdrew HELMET, finding that the HELMET dump to 2 BNB, so he activated the policy. Correspondingly, he could swap 1 HELMET for 2.25 BNB, avoiding the loss of 0.25 BNB by paying only 0.1 BNB premium.
