Bitcoin in MetaMask: Why you should put all your crypto eggs in one basket
MetaMask is integrating native support for Solana and plans to add Bitcoin, aiming to unify management of major crypto assets under one wallet interface.Summary
MetaMask, historically the primary gateway for Ethereum, is expanding to become a truly multichain wallet by adding native support for Solana and planning for Bitcoin integration by 2025. This move aims to consolidate the management of assets across Ethereum, Solana, and Bitcoin—ecosystems that previously required separate wallets and seed phrases—into a single interface using one Secret Recovery Phrase. While this offers significant convenience, it increases the 'blast radius' of risk, as one compromised backup exposes all connected chains. Consensys is pairing this rollout with account abstraction tools like EIP-7702 to enable 'invisible wallets' with features like gas sponsorship, though this also introduces new phishing risks that the wallet must mitigate with strong security alerts. Strategically, MetaMask is leveraging its 30 million monthly active users to drive adoption across ecosystems, potentially shifting user behavior by making Solana and Bitcoin easily accessible within its dominant interface, thereby competing with specialized wallets like Phantom.
