✈️ TON Connect v2.2.0 — Sign Data Support

We're excited to announce that Sign Data is now officially supported in TON Connect v2.2.0! This feature allows dApps to request signatures on arbitrary data — ideal for authentication, message signing, and more.

We kindly encourage all developers to explore and integrate this powerful capability into their dApps.

🛡 New method: signData
• Supports text, binary, and cell data types
• Enables secure off-chain data signing

📁 New package versions
@tonconnect/protocol 2.3.0
@tonconnect/sdk 3.3.0
@tonconnect/ui 2.2.0
@tonconnect/ui-react 2.2.0

🖌 Example usage

const result = await tonConnectUI.signData({
type: "text",
text: "Confirm new 2fa number: +1 234 567 8901"
});

console.log('Signed:', result);


To update, run npm install @tonconnect/ui-react@latest or npm install @tonconnect/ui@latest
