Overview

There are different ways to connect to blockchain:

1. RPC data provider or other API: in most cases, you have to rely on its stability and security.
2. ADNL connection: you're connecting to a liteserver. They might be inaccessible, but with a certain level of validation (implemented in the library), cannot lie.
3. Tonlib binary: you're connecting to liteserver as well, so all benefits and downsides apply, but your application also contains a dynamic-loading library compiled outside.
4. Offchain-only. Such SDKs allow to create and serialize cells, which you can then send to APIs.

TypeScript / JavaScript

Library	Blockchain connection	Description
ton	via RPC (Orbs / Toncenter / etc)	Convenient client library with wallet wrappers for development dApps on TON Blockchain.
tonweb	via RPC (Orbs / Toncenter / etc)	Old-style TON JS SDK, with minimal external dependencies, extensively tested in production.
tonkite/adnl	ADNL natively / via WebSocket	ADNL TypeScript implementation.
tonutils	Native ADNL	TypeScript-based interface for building and interacting with applications in TON Ecosystem. Due to native ADNL dependency, cannot be used for blockchain interaction in browser.
foton	via RPC (Orbs / Toncenter / etc)	TypeScript toolkit for interacting with TON wallets and blockchain as a whole. The library wraps existing solutions (Blueprint and TON Connect) into one comfortable API.
