(1/3) MetaMask launching its own stablecoin (mUSD) is less about competing with USDT/USDC and more about turning the wallet into a crypto neobank. That's the actual play here.
The move: wallet-native dollar balance, Treasury-backed reserves, Linea liquidity seeding, card spend at Mastercard merchants, rewards for holding and spending. All inside one funnel.
Supply is still tiny — low tens of millions — but the distribution advantage is real. Stablecoin adoption is bottlenecked by UX, not by lack of dollar tokens. If MetaMask collapses fiat deposit, onchain balance, DeFi use, and card spend into one flow, that matters.
