Blockchain Guidelines

Terms of Service

The Terms of Service for Bot Developers allow for mini apps to integrate blockchain technology, provided that the developer's implementation:

• Exclusively uses the TON Blockchain for the creation and distribution of cryptocurrency tokens or blockchain assets.
• Only interfaces with cryptocurrency wallets connected by the TON Connect SDK.
• Does not promote cryptocurrency wallets, unless such wallets are based on the TON blockchain, exclusively use TON Connect for interactions with apps, and primarily provide services related to the TON blockchain.

Important: To maintain uninterrupted access for Telegram users to their Mini Apps, developers must ensure compliance with clauses 7.1–7.4 of the Terms of Service by February 1, 2025.

Existing Mini Apps operating on other blockchains must transition to TON by February 21, 2025, including bridging existing assets, migrating smart contracts, and exclusively utilizing TON Connect.

Clause 7.1 of the Terms of Service applies immediately to all new blockchain-based initiatives, including the issuance of new blockchain-based assets. All assets issued or distributed on or after January 21, 2025 must adhere to it.
