You wrote that "We are launching a stable development project based on Robert Sam's document:" Seignorazh shares. " Is it possible to describe in more detail the information on these actions. I do not know.
The idea behind Seigniorage Shares, is to use another token to aborb the price volatility for the main price-stable token. The absorbing mechanism is based on the Quantity Theory of Money:
1. When the YDR price is > 1.0 XRD, convert YggCoin to YDR to increase the circulating supply of YDR and drive the YDR price down until it reaches exactly 1.0 XRD.
2. When the YDR price is < 1.0 XRD, convert YDR to YggCoin to decrease the circulating supply of YDR and drive the YDR price up until it reaches exactly 1.0 XRD.
The conversion ratio (YggCoin/YDR) is totally market-driven, which is done by a built-in public auction provided by the chain. Anyone can participate the auction from the wallet and profit with the price difference, keeping the token price around the desirable value - 1.0 XRD.
More detail with graphical illustration is in the first chapter of the White Paper:
