About MetaMask USD (mUSD)

MetaMask USD (mUSD) is a cryptocurrency stablecoin, launched by MetaMask in September 2025. Issued by Bridge, and powered by M0, mUSD is the first stablecoin created by a self-custodial wallet. A stablecoin is a type of token that’s designed to maintain a steady value, by being pegged to less volatile assets like the US Dollar. 

mUSD is backed by short-term US Treasury bills that are held in regulated custody and issued through a framework developed by Bridge.xyz using the M0 protocol. For every 1 mUSD in circulation, there is an equivalent dollar-backed asset held in reserve. 

MetaMask USD initially launched on Ethereum Mainnet (EVM), as well as Linea, an EVM Layer 2, where the token plays a pivotal role. Integration of mUSD includes core EVM protocols, lending markets, decentralized exchanges (DEXs), and custodial platforms. mUSD can be used in seamless fiat-to-crypto onramps, swaps, trades, and decentralized finance (DeFi). mUSD is also spendable via MetaMask Card at Mastercard merchants worldwide.

As a wallet-native stablecoin, mUSD is designed to simplify your journey across crypto, from onramping and holding to earning and spending, all within MetaMask. It enables users to move in and out of blockchain ecosystems more efficiently. Stablecoins like mUSD are vital to DeFi, underpinning trading, lending, and remittances. They also serve as a bridge between traditional finance (TradFi) and DeFi ecosystems.

24h change: -0.01%. From $0.9997 to $0.9997.

  • ConsenSys is splitting into two entities with MetaMask rebranding as the standalone consumer platform under Joseph Lubin. The focus shifts to self-custodial products including the wallet, MetaMask Card, Money Account for yield on MUSD, and related features. The transition is expected to finish by the end of 2026 and positions MUSD as a core asset for everyday use across trading, earning, and spending.
  • MetaMask launched Money Account on Monad, letting users earn up to 4 percent variable APY on MUSD holdings through DeFi vaults like Morpho with plans for Aave. Supported stablecoins convert to MUSD at 1:1 with no fees. Balances remain fully liquid for trading inside the wallet and spending with the MetaMask Card without moving funds.
  • Since its September 2025 launch, MetaMask USD has held its one-to-one peg to the US dollar with minor fluctuations. Market data across trackers shows the stablecoin trading between 0.9996 and 1.00 with circulating supply in the 15 to 33 million range. This stability supports its use for payments, on-chain activity, and yield generation inside the MetaMask ecosystem.

24h change: +0.00%. From $0.9998 to $0.9998.

  • MetaMask is responding to a security incident affecting part of its infrastructure by proactively exiting Ethereum validators operated through the Lido protocol. The incident involved redirection of roughly 0.36 ETH in staking rewards, equivalent to under $1,000, with validators holding around $1.4 billion in staked ETH being withdrawn as a precaution. MetaMask has stated there is no immediate threat to user wallets, secret recovery phrases, or customer funds, and validator keys have been rotated. Lido noted potential lost rewards and that full withdrawal of the ETH could take weeks. This event underscores security vigilance in staking infrastructure but has not directly impacted mUSD operations.
  • MetaMask's Money Account allows users to earn variable APY on mUSD balances automatically with no lockups or manual staking. Users can convert other stablecoins to mUSD at 1:1 parity with no fees for supported assets and spend via the MetaMask Card at Mastercard merchants. Built on Monad as its home chain, the feature integrates onramping, trading, sending, and earning in one self-custodial experience. mUSD, launched in September 2025 and issued via Bridge using the M0 protocol, remains backed by regulated short-term US Treasury reserves with attestations.

  • MetaMask is responding to a security incident affecting part of its infrastructure by proactively exiting Ethereum validators in its non-custodial staking operations through Lido. The company states it has identified no immediate threat to MetaMask wallets or customer funds, and staking operations do not manage user withdrawal keys. Lido has noted the process could result in forgone rewards and may take until early October for full exit. This precautionary action demonstrates focus on protecting users of the MetaMask ecosystem that includes mUSD.
  • MetaMask launched Money Account, a self-custodial feature that lets users earn up to 4 percent variable APY on mUSD and other stablecoins automatically with no lockups or manual actions. Built primarily on Monad, it integrates yield from DeFi vaults like Morpho with direct spending through the MetaMask Card at Mastercard merchants and trading features. Users can convert supported stablecoins to mUSD at 1:1 with no fees or purchase mUSD directly in-wallet. This expands the utility of mUSD beyond holding to everyday financial activities inside MetaMask.

  • In late June 2026 MetaMask introduced the Money Account, a self-custodial feature built on the Monad blockchain. Deposits of mUSD or other stablecoins automatically earn variable yield up to four percent by routing through vaults into protocols such as Morpho and planned Aave integration. The account combines earning, spending with the MetaMask Card at Mastercard merchants, and trading without requiring users to move funds between applications. This reflects a broader effort to make stablecoins useful for everyday financial activities inside your wallet.
  • In September 2026 Consensys announced it is splitting into two independent companies. The existing entity will become MetaMask and concentrate on consumer wallet experiences including mUSD and Money Account features. A new Consensys will handle Ethereum protocols, Linea, and institutional blockchain infrastructure. The change is expected to complete by the end of 2026 and positions MetaMask to accelerate development of everyday crypto tools such as yield accounts and card spending.
  • Recent on-chain activity shows mUSD liquidity increasing through MetaMask Money Account deposits. Over 20 million dollars in deposits reached Aave's Monad market with high utilization as wallet balances flow directly into lending protocols. This integration allows users to earn yield without manually managing positions across applications. It demonstrates how wallet-native stablecoins can contribute to deeper DeFi liquidity on newer high-performance chains like Monad.

  • Consensys announced plans to split into two independent entities in early September 2026. The consumer business will rebrand as MetaMask under Joe Lubin as chairman and CEO, with a focus on products like mUSD and the Money Account. The institutional infrastructure and Ethereum protocol work, including Linea, will form a new Consensys company. The separation is expected to complete by the end of 2026 and aims to sharpen focus on consumer-facing crypto tools.
  • As of September 27, 2026, mUSD trades at approximately $0.9998 with minimal deviation from its peg. Market capitalization sits near $25-28 million across tracking platforms, with 24-hour volume ranging from $3 million to $5.5 million. Circulating supply is reported between 15 million and 28 million tokens depending on the source. The stablecoin continues to see use across Ethereum, Linea, and Monad without notable depegging events in recent months.
  • The Money Account feature, launched in June 2026, lets users deposit into mUSD and automatically earn variable yield of up to 4% APY through DeFi vaults on protocols like Morpho and Aave. Funds remain available for instant spending via the MetaMask Card at Mastercard merchants or for on-chain trading without leaving the wallet. The product is built on Monad as its primary chain and emphasizes self-custody with no lockups or manual claiming of rewards. It reflects MetaMask's push to combine traditional banking-like functions with decentralized tools.
