There are several ways to interact with TON blockchain:
  • HTTP libraries connect through HTTP JSON APIs to read and write to the blockchain. HTTP servers mostly relay these requests to the ADNL network.
  • ADNL libraries connect to liteserver.
Here’s a small comparison of these protocols: 1 Some HTTP servers do provide proofs, but there is no out‑of‑the‑box library that verifies them.
2 If proofs returned by liteservers are ignored, the first connection skips data synchronization; however, this requires trusting the liteserver. SDKs might also provide some other functionality:
  • Core libraries implement standard TON data structures (cell, slice), formats (address, mnemonic), cryptography, etc.
  • Wrappers provide high-level APIs for interacting with standard contracts (Wallet, Jetton, NFT).
  • Emulator libraries provide an execution environment similar to a real blockchain for testing purposes.
