SDKs

Easily navigate to your preferred programming language using the right sidebar.

Overview

There are different ways to connect to the blockchain:

1. RPC data provider or other API – Requires stability and security from a third-party service.
2. ADNL connection - Connects to a liteserver. While it may be inaccessible at times, it cannot provide false data due to built-in validation.
3. Tonlib binary - Also connects to a liteserver, inheriting the same advantages and limitations. However, your application includes a dynamically loaded library compiled externally.
4. Offchain-only - These SDKs allow you to create and serialize cells, which can then be sent to APIs.
