MetaMask brings mUSD to millions of self-custody wallets with M0
THE PARTNER
MetaMask is the world's leading Open Money platform, trusted by millions of users globally. Built by Consensys, founded by Ethereum co-founder Joseph Lubin, MetaMask is the primary gateway to Web3, enabling users to securely manage crypto assets and interact with decentralized applications across both EVM and non-EVM networks like Bitcoin and Solana. Their core values center on self-custody, security, and trust: protecting users and enabling true ownership of their assets.
THE CHALLENGE
There were billions of dollars in stablecoins sitting idle across MetaMask wallets, not earning rewards, not easily spendable, just parked. MetaMask identified a massive opportunity to change that. The vision: a seamless, wallet-native money experience where holding digital dollars automatically gives users the best of Web3 and traditional finance without navigating dApps, signing complex transactions, or stitching together fragmented tools.
Executing on that vision required meeting three non-negotiable standards:
- Modularity: MetaMask needed to own the user experience without building every layer of the stack - distribution, issuance, interoperability, and compliance are each deep specializations.
- Issuer flexibility: Serving a global user base across diverse regulatory environments meant locking into a single issuer was not an option. They needed the ability to work with multiple issuers and adapt over time.
- Speed: The stablecoin market was moving fast. Traditionally, launching a stablecoin takes over a year. MetaMask needed a path measured in weeks, not years.
WHY M0
M0 stood out immediately, not just for its technology, but for how the team showed up. The combination of hands-on partnership and on-chain infrastructure made M0 the clear choice.
Three technical differentiators were decisive:
- Full on-chain transparency: M0's infrastructure means every minting, burning, and reward distribution operation is fully verifiable on-chain - directly aligned with MetaMask's core ethos of openness and self-custody.
- Multi-issuer architecture: M0's shared liquidity layer gave MetaMask the flexibility to launch with Bridge (a Stripe company) as their first issuer while retaining the option to onboard additional issuers as the product scales into new markets.
- Speed to market: M0 compressed what would have been a year-plus build into weeks — enabling MetaMask to go from concept to a live, fully-backed stablecoin in record time.
M0 operates with full transparency, aligning with our core ethos of openness and self-custody. The platform also delivers the robustness and scale we need to serve a global user base.
MetaMask built mUSD, a wallet-native stablecoin pegged to the US dollar, directly on M0's modular stablecoin infrastructure. The result is a stablecoin that lives inside the wallet users already trust, enabling them to on-ramp, earn, spend, trade, and move between fiat and crypto without ever leaving MetaMask.
mUSD is fully backed and interoperable with DeFi from day one, thanks to M0's shared liquidity layer. The minting and burning mechanism, along with reward distribution, runs entirely on-chain giving MetaMask's users the same transparency guarantees as the wallet itself.
THE OUTCOME
With mUSD live, MetaMask users can now hold US dollar-pegged value that works across the entire MetaMask ecosystem: Card payments, Rewards cashback, reward opportunities, and smooth transfers between trading and spending - all under full self-custody. What was previously billions in idle stablecoins can now earn, spend, and move. mUSD sits at the center of a more connected financial experience, making the gap between crypto and everyday life narrower than it has ever been.
M0's infrastructure made it possible to ship a programmable stablecoin in a fraction of the time a traditional build would have required without sacrificing modularity or the flexibility to scale.
WHAT'S NEXT
MetaMask's ambition extends well beyond the initial launch: mUSD is designed to become the foundational layer of a new generation of money management inside MetaMask — one where holding, earning, spending, and moving digital dollars globally feels as intuitive and natural.
