Cross-chain adoption is another growth driver. Linea, a Layer 2 (L2) network, has positioned $mUSD as its default stablecoin, anticipating a boost in total value locked (TVL) as developers build lending markets and decentralized exchanges (DEXs) around itMetaMask mUSD Stablecoin Launch 2025: Everything You Need^[1].

Fee-Based Revenue: Unlocking New Monetization Streams

While specific fee structures for $mUSD-related transactions remain undisclosed, the stablecoin's design opens multiple revenue avenues. Transaction fees for cross-chain bridging, on-ramp services, and DeFi protocol integrations could generate recurring income for MetaMaskMetaMask USD (mUSD) Explained: Why a Wallet-Native Stablecoin^[2]. Additionally, yield-sharing mechanisms—where users receive a portion of treasury returns from U.S. Treasury bill holdings—could incentivize long-term holding and increase TVLMetaMask mUSD Stablecoin: Everything You Need to Know About^[5].

Institutional partnerships further amplify revenue potential. By leveraging Stripe's Bridge for compliance and Blackstone for treasury management, MetaMask reduces operational costs while attracting institutional capital.
