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