MetaMask Introduces Unified Multi-Chain Account for All Blockchains
MetaMask has announced a major upgrade that allows users to manage all their blockchain addresses from a single account — marking a shift from its original “one account per network” model to a unified multi-chain architecture.
From Ethereum-only to universal wallet
Originally built for the Ethereum ecosystem, MetaMask required users to create separate accounts for each supported network. Even EVM-compatible chains such as Polygon, BNB Smart Chain, and Avalanche needed individual addresses, while non-EVM networks like Solana were completely isolated.
As of October 27, this is changing. The new **unified account system** introduces a single wallet identity that can hold addresses across multiple blockchains — including Ethereum, EVM Layer-2 networks, and Solana. Future updates are expected to extend compatibility to **Bitcoin** and other major non-EVM chains.
A step toward seamless cross-chain experience
The change brings MetaMask closer to becoming a **truly multi-chain wallet**, reflecting the growing convergence between blockchain ecosystems. Instead of treating networks as isolated silos, the new design allows assets and decentralized applications to coexist under one account structure.
For developers, this opens up new opportunities to build cross-chain DeFi platforms and NFT marketplaces that operate seamlessly across different infrastructures.
How it works
Each account within the updated MetaMask interface now includes a **hierarchical key system** capable of deriving addresses for multiple networks. While the underlying cryptography remains secure, the wallet automatically maps and manages private keys for different blockchains through a unified user interface.
This allows users to send, receive, and interact with assets from different chains without juggling multiple profiles or browser extensions.
Implications for users and the crypto industry
The update simplifies the experience for millions of MetaMask users who previously had to maintain multiple wallets for separate ecosystems. It also sets a new precedent for interoperability — a key theme in the next stage of crypto infrastructure development.
Industry observers believe MetaMask’s unified approach will accelerate mainstream adoption by reducing the technical friction that has long deterred newcomers.
What’s next
In upcoming releases, MetaMask plans to expand the unified system to include **Bitcoin support** and improved cross-chain bridging tools. Developers are also testing new APIs for dApps to detect and interact with multi-network accounts automatically.
With this move, MetaMask cements its position as the leading non-custodial wallet, evolving from an Ethereum gateway into a universal access layer for the decentralized web.
