Wyoming recently announced testing its state-issued stablecoin - WYST, marking the entry of the first stablecoin in the United States issued by a public entity into the experimental phase. WYST is currently being tested on the testnets of seven blockchains including Avalanche, Solana, and Ethereum, aimed at ensuring its multi-chain compatibility. The stablecoin will be backed by cash and U.S. Treasury bonds in excess, with the interest generated used to fund Wyoming's education fund. However, Charles Hoskinson, the founder of the Cardano blockchain, expressed dissatisfaction over its exclusion from the tests, reflecting the controversy surrounding the project's choice of blockchains. Overall, the launch of WYST showcases Wyoming's innovation in the digital asset space, but its actual impact still needs further observation.
