This not only means we will be able to support @solana, Bitcoin, and other L1 networks and addresses - but also support any DIDs like @farcaster_xyz 

Everyone deserves MLS level privacy and security that is decentralized with @xmtp_ - and now you'll be able to bring that to any identity of your choice. You own your identity, and now you can connect it to your messages - and own them too! 

Learn more about Passkey support and what this means for XMTP here https://community.xmtp.org/t/xip-55-passkey-identity/874

Here's how this works:

1. Your device securely stores a passkey
2. This passkey controls your XMTP ID, just like a private key controls your crypto wallet

3. You log into your inbox app with your XMTP ID and another identity you own (e.g. Solana wallet)
4. Both identities sign a message to prove ownership and agreement

5. XMTP publishes the message onchain for anyone to verify the link.

You can also use XMTP with only a passkey.

Or multiple passkeys, so you can access the same inbox from any app/device.
