SDKs

For available APIs, see the API overview.

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:

	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 a real blockchain for testing purposes.
