💎 Anatoly Makosov shared a closer look at the technology behind Gram Wallet on his 𝕏. We’ve included the details below for easy reading, or you can read the original thread here.

Behind the simple feature set of Telegram’s first Gram Wallet release is a range of technical innovations and close attention to UX:

1. All operations happen onchain through smart contracts.

2. You can send Gram to someone who has never opened their wallet or even updated Telegram.

3. Cloud backup makes the same wallet available across all your devices without importing it manually on each one. The seed phrase is split into three parts, stored in separate data centers on three continents.

4. You can disable cloud backup, rotate your seed phrase while keeping the same wallet address, and later import the wallet into another app, such as the standalone Gram Wallet app.

5. Connecting to a dapp through TON Connect makes the connection available across all your devices. There is no need to reconnect on each device.

6. Five free transfers per day, powered by Gasless & Sponsored Transactions. Further transfers cost next to nothing thanks to this year’s network fee reductions.

7. A network-wide validator vote can upgrade the Telegram wallet’s smart contract to add new functionality. The upgrade applies to all users at once, without requiring a migration. Telegram itself cannot bypass the blockchain’s rules to force wallet upgrades.

This UX combines existing TON capabilities with new developments. It builds on TON’s original architecture, where every account is a custom smart contract that can implement arbitrary logic, alongside the previously released Gasless Tx, Sub-Second, and Sub-Cent updates.

New components include Telegram’s own TON Connect implementation, the tg-wallet-v1 smart contract with key rotation support, a dedicated wallet proxy contract, and other technical innovations.

💜 We’re happy to have contributed to building it! Enjoy the new wallet in Telegram and let us know what you think.
