Ethereum’s multichain wallet

Multichain Accounts are here

Multichain Accounts for MetaMask are here. This is a big change for how accounts work in MetaMask, and it's one that will vastly simplify the crosschain experience for our users.

Beyond the EVM

MetaMask has long set the standard for multi-network support in the web3 ecosystem. Users and developers alike relied on MetaMask to give them powerful and open-ended support for any network that they wanted to be a part of. The catch? They had to be EVM networks.

As crypto’s multichain ecosystem has matured over the last few years, more users have been doing more things across more networks: beyond Ethereum to its L2 networks, and further beyond to non-EVM chains like Solana. And of course, Bitcoin.

Changing user behaviour

Simultaneously, the number of networks that users transact across has been steadily increasing: our legacy account architecture—one separate account for each network and private key—was quickly becoming cumbersome and untenable, even among EVM networks.

Enter: BIP-44 and Multichain Accounts. We rearchitected the entire account experience in-wallet by moving the "account" up one level of abstraction. An account now contains a parallel set of keys across a range of supported networks. This multichain account keeps the keys for Ethereum, Linea, Arbitrum, Base, Solana, Bitcoin, and other networks all together in a group, and all still generated from one seed phrase.

Now, users only need to think about singular accounts as operating across a range of chains, rather than a patchwork of accounts that they have to manually maintain. A multichain account naturally lists the total of your assets across all the chains within that account, giving users a more convenient, single-stop view into their holdings.

How multichain strengthens Ethereum

Ethereum isn't at the center of our wallet–the user is. We believe it's important to meet users where they are and take them where they want to go, giving the best wallet experience on whatever network they choose. This both supports the needs of our existing users, and gives new users of those ecosystems the choice to use our wallet. But this doesn't mean we're less committed to Ethereum, far from it. 

We also believe Ethereum is the backbone of web3, and will be the rails on which our global financial system will be rebuilt. By improving seamless connectivity between all networks and Ethereum, users across chains are better able to eventually migrate their assets and activity to include Ethereum, and wherever else they want to go. All roads lead to Ethereum.
