Smart wallets will onboard the next billion. XIP-44 brings them to XMTP using ERC-1271 signature verification.

This means any smart contract that adds the ERC-1271 interface can use the network directly.

Voila: trustless business messaging for NFT creators, DeFi protocols, DAOs, etc.

Family just released the best web3 messaging feature we’ve seen yet @xmtp 

It’s Apple Cash but global, permissionless, and decentralized.

Just launched support for Paragraph frames on @xmtp.

Subscribe, read in-line, and (coming soon) collect Paragraph posts without ever leaving your XMTP client.

This enables a more seamless way for creators to grow & monetize, while making it easier for readers to engage with you & your content directly from a DM.

Was so cool to see @paragraph frames just appear in @converseapp without a software update. Composability is magic.

Messaging for web3 people. Built with @xmtp https://converse.xyz/ /converse

Web3 newsletters & publishing.

We automatically summarize and cast about the best posts on Paragraph.

Open Frames

Announcing... Open Frames

Open Frames is a draft specification for Frames that work anywhere.

If you're interested in bringing Frames to your ecosystem or app, DM us, we'd love to chat.

XMTP is launching Frames support using Open Frames today.

Read more: https://github.com/open-frames/standard/blob/v0.0.1/README.md

What excites me the most about /open-frames is that each new context inspires new experiences.

Feeds -> multiplayer, public
Group chat -> multiplayer, private
DMs (+ bots) -> single-player, private

Congratulations @df @nickm @mg on extending Frames into these new canvases, and more to come.

XMTP is getting Universal Allow/Block Prefs (✅/🛑) and I’m stoked.

You can read the technical details of XIP-42 here (https://community.xmtp.org/t/xip-42-universal-allow-and-block-preferences/544), but I also wanted to share what went into it and how it makes the /xmtp experience way better.

So what is it? 👇

Proud of the XMTP core dev team’s work on XIP-42.

You’ve never had this kind of control over your communications.

BDFL of Quilibrium, Eng @ Farcaster, ex-Coinbase, always opinionated, never hydrated

All true for v2. Next week XMTP v3 moves to dev alpha with support for:

✅ Installation / per-app keys
✅ Perfect forward secrecy
✅ Post-compromise security
✅ More modern curves for cryptography
✅ Group chat
✅ Mutable metadata for conversations
✅ New database-first design that’s faster

If XIP-42 universal allow/block got you pumped today, just wait for what’s next in XMTP shipping szn.

Stoked to talk about Frames extensions on the @xmtp dev call next week.

Also, big update on e2ee group chat. 😇

What would you build if Frames could slide into XMTP DMs?

Farcaster Frames are so well done and it’s so exciting to see a developer ecosystem get this excited. Super kudos to @dwr.eth and @v - just awesome. 

Thinking a lot about how to help devs extend Frames even further. 

Love to hear ideas how to support this community more.

What Shane said. Can't wait to see how creators and devs build and maintain real relationships using the interactivity Frames have unlocked.

Great post by our engineering team on one of the more difficult DX tradeoffs we've made in service of privacy.

We're hiring a data scientist at @xmtp Labs. Must thrive in a privacy-by-design environment. Experience with homomorphic encryption is a strong plus.

My DMs are open:

1/ It's been inspiring to see the developer community coming together to tackle spam on the 
@xmtp
 network.

Early efforts include:

📥 Message requests tabs
🤖 Real-time proof-of-personhood
💯 Sender reputation scores
🕵️ Impersonation detection
🎁 Data co-ops & public goods

🧵

Kicking off the inaugural @xmtp Inbox Safety Council meeting in just a few w/ CB Wallet, Converse, UD, Orb, Lenster.

First topic is spam countermeasures.

We’ll also discuss meeting transparency and inclusivity.

This weekend, some @xmtp users, team members, and developers got hit by phishing attempts from vanity addresses (such as “0x0000…0000”) meant to look like the Ethereum null (or burn) address.

That actual null address is controlled by nobody and can never send messages on XMTP.
