Independent MIT-licensed server SDKs for the Fragment Donor public API in Python, TypeScript, PHP, .NET, Go, Rust and Ruby. The private production backend and its history are not part of this project. Username lookup, wallet balance and intended Stars/Premium gifting use a form-urlencoded contract. Wallet operations submit sensitive credentials to a backend that stores them; purchases never retry automatically and there is no idempotency guarantee. Mocked contract and package tests make no real purchases. English, Russian and Uzbek documentation is available from the canonical GitHub project. This is not an official Telegram, Fragment or TON product.
