Web3 is missing a secure and composable messaging primitive. Today, we’re fixing that. Introducing the Sui Stack Messaging SDK - private, programmable, wallet-linked messaging for apps on Sui. Here’s how it works 👇

🔑 The Vision Builders today rely on fragmented or off-chain messaging. The SDK changes that: - Native messaging inside Sui apps - Private by default - Recoverable across devices - Composable with onchain workflows and across apps

💡 What is it? The Messaging SDK = 3 powerful layers combined: 1️⃣ Sui smart contracts for channels & encrypted messages 2️⃣ Walrus decentralized storage for encrypted attachments 3️⃣ Seal encryption with programmable access control

✨ Features: - 1:1 & group chats, wallet-linked - End-to-end encryption for messages + attachments - Onchain storage for verifiable communication - Recoverability across devices - Programmable messaging flows (token-gated, event-triggered, role-based)

🔍 Why it matters Most current options are: - Off-chain, centralized, siloed - Wallet-only, no programmability - Ephemeral, not persistent - Difficult to recover across devices without relying on centralized servers The SDK fills the gap with private, programmable, verifiable communication.

🏗️ Use Cases - Customer support directly in-app - DAO chats & token-gated communities - Cross-app workflows (Trading marketplace ↔ DeFi lending) - AI agent coordination - Event-driven notifications & messaging - Privacy-first social apps

⚖️ How it compares Compared to other Web3 messaging: - Programmable access control (Seal) - Decentralized verifiable storage (Walrus) - Onchain integration with contracts & events (Sui) This is a full-stack messaging primitive, not just a chat library.

⚠️ Note: The SDK is in alpha and on Testnet only. So experiment, give feedback, and help shape the future of messaging on Sui.

This is just the beginning more to come stay glued coming uptober 🥶

LFG!!

This is why you build a full stack! 🔥 Walrus + Seal + NS = Win!

SUIIIIIIIII 🌊

Much potential in it 🦾

$ICP has @OpenChat for a long time, and that's 100% fully on-chain Further anyone(without experience of code and deployment) can build an App like this in minutes with @caffeineai (and No AWS required like $SUI) #caffeine #caffeineAI

Sui + walrus+ seal +NS = future of internet

That’s what I’m talking about! Sui ahead of the curve 🌊

$SUI is truly limitless—just like $ZENGAR, the next 1000x 🚀 @zengarsui

Sui messaging unlocks new dApp layers, watch liquidity surge as developers sprint to integrate

Sui about to change messaging as we know it

FIRE 🔥

Thanks for the upgrade

🔥

Good upgrade

If this gains traction, the “super apps” of Web2 (Meta, Telegram, TikTok) suddenly have open-source, trustminimized challengers.

LFG! 🚀🔥

LFG Sui is the alpha🔥

Sui shaking up the game 🌊

Nice, let's pump $manifest

This is amazing

The innovation in SUI chain is top notch

Secure, wallet-linked messaging is exactly what Web3 needs. Excited to see Sui Stack fill this gap 🔥

SUI = UTILITIES

$SUI keeps shipping, love it Imagine $AAA raids powered by this 🐱

Big step forward for $SUI devs

SUI $10 to the moon

@bharathdotsui Sui is everywhere💙

amazing

Awesome!!!!

this is crisp engineering 12 love to see the flows that wowed you

On-chain messaging oh my goodness about time we get to it. Once again Sui is bringing the future of web3 early

Lfg🔥
