Arc names MetaMask as default wallet for seamless onboarding

Arc: Arc is a Layer-1 blockchain developed by Circle, the issuer of USDC, built as a stablecoin-native network where transaction fees and native balances are denominated in USDC and other supported stablecoins at the protocol level. It is EVM-compatible and targets institutional finance and DeFi use cases with features like native asset support and deterministic settlement. The news announcement establishes MetaMask as its default browser and mobile wallet to provide builders a familiar onboarding path into Arc applications. MetaMask: MetaMask is a widely used self-custody browser and mobile wallet that connects users to blockchains and decentralized applications with standard connect, sign, and asset management flows.

In this development, MetaMask is positioned as the default wallet for Arc, enabling trusted and seamless access to the chain's stablecoin-native ecosystem for both builders and end users. Chain Design: Arc functions as a stablecoin-native Layer-1 blockchain with USDC serving as the primary gas token and settlement asset at the protocol level. Ecosystem Focus: Arc emphasizes EVM compatibility and institutional-grade features to support composable stablecoin and tokenized asset applications from launch. Wallet Partnership: MetaMask is listed among day-one ecosystem partners for Arc, alongside other wallets and infrastructure providers.
