What is the project about? The Metal Dollar (XMD) represents an innovative approach to stablecoins, operating on the Proton Blockchain. Its design brings increased stability, transparency, and efficiency to digital transactions. Uniquely, XMD is backed by an array of established, non-algorithmic bank reserve-backed stablecoins, including USDC, USDT, and PAX, a method intended to mitigate risks associated with single-issuer or algorithmic stablecoins and enhance stability.
