This is amalgam.

Amalgam, built on the Ethereum blockchain, is fundamentally safer than almost all of its contemporaries. Additionally, Amalgam has real world use and its value is safeguarded in its correspondence to a price-weighted index of over 300 of the world’s most frequently traded cryptocurrencies available on the market. This allows Amalgam to be valued by its demand as an asset, its transactional frequency, and the overall health of the cryptocurrency market, further mitigating the risk of dilution or extreme depreciation.
