Dai (Dai) is a usd-stablecoin built on the ethereal blockchain without centralization. Its $1 equivalent is maintained through an automated pricing mechanism built into smart contracts. When Dai's value exceeds $1, smart contract pricing mechanisms will lower prices. Conversely, when Dai's value is less than $1, smart contract pricing mechanisms increase prices. Dai can trade freely like any other ERC20 token, and anyone with an etheric wallet can own, accept and transfer without the need for a middleman.
