TON HTTP-based APIs

There are different ways to connect to TON Blockchain:

  1. RPC data provider or another API - You must rely on its stability and security.
  2. ADNL connection - Connect to a liteserver. While it may be inaccessible at times, it cannot provide false data due to library-implemented validation.
  3. Tonlib binary - Also connects to a liteserver, so it shares 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 you can then send to APIs.

Pros & Cons​

  • ✅ Easy-to-use - Ideal for newcomers exploring TON.

  • ✅ Web-oriented - Suitable for loading data from TON smart contracts via the web and sending messages.

  • ❌ Simplified - Does not provide indexed TON API data.

  • ❌ HTTP-middleware dependency - Server responses cannot be fully trusted unless augmented with merkle proofs to verify authenticity.

RPC nodes​

TON infrastructure status
  • status.toncenter - Displays various node activity statistics from the last hour.

Indexer​

Toncenter TON index​

Indexers allow you to list jetton wallets, NFTs, and transactions using filters, rather than retrieving only specific ones.

Anton​

Anton is an open-source TON Blockchain indexer written in Go and licensed under Apache 2.0. It offers a scalable, flexible way for developers to access and analyze blockchain data. Developers can also add custom smart contracts with custom message schemas.

GraphQL nodes​

GraphQL nodes also function as indexers.

  • dton.io - Provides contract data according to contract type. It also supports transaction emulation and execution trace retrieval.

Other APIs​

  • TonAPI - A user-friendly API that abstracts low-level smart contract details for a streamlined experience.
