SDKs

There are several ways to interact with TON blockchain:

• HTTP libraries connect through HTTP JSON APIs to read and write to blockchain. HTTP servers mostly just relay these requests to ADNL network.
• ADNL libraries connect to liteserver.

Here’s a small comparison for these protocols:

	HTTP	ADNL
Standardized	No	Yes
Can connect from a web page	Yes	No
Has free third-party servers	Yes	Yes
Can be self-hosted	Yes	Yes
Requires trusting third parties	Yes1	No
First connection takes time for data synchronization	No	Yes2

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 real blockchain for testing purposes.
