Web3 has long lacked a secure and composable messaging primitive.
Today, Sui is here to change that—introducing the Sui Stack Messaging SDK!
💬 A private, programmable, wallet-bound messaging tool designed specifically for Sui applications.
👇 Learn how it works:
🔑 Vision
Currently, developers rely on fragmented or off-chain messaging, but the SDK changes that:
- Native messaging within Sui applications
- Default privacy
- Recoverable across devices
- Compatible with on-chain workflows and cross-application combinations
💡 What is it?
Messaging SDK = A powerful combination of three layers of technology:
1️⃣ Sui smart contracts → Channels & encrypted messages
2️⃣ Walrus decentralized storage → Encrypted attachments
3️⃣ Seal encryption → Programmable access control
✨ Feature Highlights:
- One-on-one or group chat, wallet binding
- End-to-end encryption for messages and attachments
- On-chain storage → verifiable communication
- Cross-device recovery
- Programmable message flows (token gating, event triggering, role control)
🔍 Why is it important?
The current majority of solutions are:
- Off-chain, centralized, fragmented
- Only wallets → No programmability
- Temporary existence → Not persistent
- Cross-device recovery relies on centralized servers
The SDK fills the gap, bringing private, programmable, and verifiable communication.
