Fact Check
Multiple independent sources (MEXC, Blockonomi, CoinFi, X) corroborate the plan for MetaMask to launch a stablecoin named mUSD. The evidence explicitly links this launch to a partnership with the Ethereum layer-2 network Linea. Given MetaMask's origin and primary function as an Ethereum wallet, it is virtually certain the stablecoin would also launch on Ethereum. The high degree of corroboration across different platforms provides strong evidence for the statement.
