By Marco Piccolo

The initial proposal leak: What we know about mmUSD

On the evening of the leak, the cryptocurrency community was abuzz with a proposal regarding MetaMask’s potential new stablecoin, mmUSD. The proposal, which surfaced on the Aave governance forum, hinted that MetaMask was working on launching its own U.S. dollar-pegged stablecoin. While the post was soon deleted, the contents were enough to fuel speculation.

According to the proposal, the mmUSD stablecoin would serve as a cornerstone asset for MetaMask’s ecosystem. The goal is for mmUSD to act as a highly liquid, neutral base currency that can be used across MetaMask’s wallet, swap, and decentralized finance (DeFi) services. The stablecoin would be integrated deeply into MetaMask’s suite of products, facilitating seamless crypto transactions within decentralized applications.

While no official confirmation has been made by MetaMask or Stripe, the details revealed in the leaked proposal suggest that the project is far from being just an idea. In fact, the M^0 network is expected to support the stablecoin’s minting and redemption, making mmUSD an on-chain asset with a robust infrastructure backing it.

Stripe’s role and potential impact on the project

Stripe, the fintech giant that has already made moves in the crypto space, would play a crucial role in MetaMask’s stablecoin strategy. With Stripe’s infrastructure, the stablecoin could bridge the gap between traditional banking systems and blockchain technology. The partnership promises to enhance the efficiency of fund transfers between crypto wallets and financial institutions, a critical aspect for fostering adoption in a sector that often struggles with high fees and slow transaction speeds.

However, Stripe’s involvement could also bring regulatory scrutiny. Stablecoins have faced increasing attention from lawmakers, and partnerships like this may invite more discussions around how these digital assets will be regulated in the future.

The DeFi landscape and the need for a native stablecoin

Stablecoins have become a cornerstone of decentralized finance (DeFi) due to their ability to maintain a stable value while providing the flexibility of cryptocurrencies. As of 2025, the stablecoin market is valued at over $250 billion, and with MetaMask’s growing influence in DeFi, mmUSD could position the platform as a major player in the ecosystem.

The top 5 largest stablecoins have a combined market capitalization of nearly $250 billion.

However, MetaMask’s move into stablecoins comes at a time when other companies, such as PayPal and Bank of America, are also exploring similar projects. This could lead to fierce competition, as traditional financial institutions and fintech firms alike rush to create their own stablecoin offerings.

Despite the competition, MetaMask’s established presence in the Web3 ecosystem could give mmUSD a unique advantage. If MetaMask can effectively integrate mmUSD into its existing product suite, it could see widespread adoption among DeFi users who are already familiar with the MetaMask wallet.

What happens next for mmUSD?

With the leak causing significant buzz, the immediate next steps for mmUSD are unclear. MetaMask has not provided official commentary, and there is no timeline for the official launch of the stablecoin. Given the market’s current state, the development of mmUSD could accelerate depending on regulatory clarity and market demand.

The question remains: can mmUSD stand out in an already crowded stablecoin market? While the initial excitement is palpable, there are concerns over its potential impact on MetaMask’s user base and the broader DeFi landscape. Furthermore, the lack of official confirmation leaves many wondering if the project will ever come to fruition or if it’s just a passing experiment.
