Shield Token is a series of smart contracts that allow anyone to issue and trade tokenized assets. The price and state of the real-world assets are tracked and monitored by an oracle. A dynamic balance mechanism is implemented to enable minters and traders to obtain maximum benefits. In the meantime, the staking pools ensures the market price is stable and full of vitality. A synthetic asset issued on Shield is called an sAsset. For instance, a synthetic version of real-world asset Google would be called sGoogle.The Shield protocol utilizes AMMs (automated market makers) to facilitate sAssets trading against stablecoins. A critical function of the Shield protocol is the ingestion of asset price data external to the blockchain. This is necessary for determining the amount of collateral required for minting an sAsset, and for assessing whether or not sufficient collateral is locked for existing sAssets. The protocol achieves this via an oracle mechanism. Shield token holders submit votes on each asset, which the protocol aggregates to compute a median weighted by each holder’s Shield token stake. The Shield oracle submits prices at a high frequency to accommodate real-time pricing of exchange-traded assets.
