Account Management Snaps: Support non-EVM address

[AnthonyLaw]

Introduce

Using Keyring to create an account and the account shown in metamask is cool stuff.

I was thinking if it allows adding non-evm addresses in the metamask wallet even awesome.

Advantage

• If creating non-evm account can be directly handled in metamask, instead of a custom page, it will speed up non-evm account implementation.
• For users, easy for them to manage accounts, all account (snap) is shown in metamask.

Summary

I was exploring keyring with non-evm accounts, and I successfully created the non-evm account, but there was an error.

when this event is triggered.
await this.#emitEvent(KeyringEvent.AccountCreated, { account });

Hey @AnthonyLaw, we are indeed considering supporting non-EVM accounts!

The Keyring API was made with this feature in mind, but we need to make some internal changes to MetaMask first. Essentially, we need to support non-EVM addresses in the UI and be able to interact with their chains to get balances and broadcast transactions.

TL;DR: That’s a really cool idea, we will think about it!
