📝 Sign Arbitrary Data with TON Connect

The latest update to our TON Connect implementation introduces a powerful new feature: the ability to sign arbitrary data — from plain text and binary blobs to BOC (cell) format.

This unlocks new use cases in the TON ecosystem: secure off-chain flows, verifiable signatures, and advanced on-chain logic — all through the familiar TON Connect interface.

Now supported in the latest versions of Tonkeeper on iOS and Android.
