[Objective Labs] Integrate mUSD on Euler Yield

Summary

Objective Labs recommends integrating MetaMask USD (mUSD) into Euler Yield as both a collateral-enabled and borrowable asset. mUSD is positioned to become one of the most widely adopted stablecoins due to its native integration into MetaMask, the world’s leading self-custodial wallet. Onboarding mUSD strengthens Euler Yield’s stablecoin market, enhances collateral diversity, and positions the protocol to capture new user flows from MetaMask’s global ecosystem.

Fundamentals

MetaMask USD (mUSD) is a fiat-backed stablecoin issued by Bridge, a regulated subsidiary of Stripe, and is designed to be natively integrated into the MetaMask wallet. It is fully collateralized on a 1:1 basis with cash and U.S. Treasuries, ensuring a high-quality and liquid reserve backing. The minting process allows users to convert fiat into mUSD directly within MetaMask through bank transfers, card payments, and other supported on-ramp services. Redemption works in the opposite direction, enabling holders to convert mUSD back into fiat via MetaMask’s off-ramp partners. The token is powered by M0, a decentralized stablecoin infrastructure that facilitates issuance, redemption, and cross-chain liquidity. Initially launching on Ethereum and Linea in 2025, mUSD will be seamlessly embedded into the MetaMask wallet for swaps, bridging, and DeFi interactions, with future expansion into real-world payments through the MetaMask Card in partnership with Mastercard.

Gauntlet supports onboarding mUSD to Euler Yield with conservative parameters, considering its early stage of development. We align with Objective Labs’ recommended caps, IRMs, and LLTVs.

mUSD is a promising integration asset for Euler Yield, but due to its limited on-chain track record, we recommend utilizing a conservative approach and monitoring user adoption over the coming weeks before increasing caps. We believe that Objective Labs’ recommendations are in line with this approach.
