# 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](/ecosystem/node/overview).
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.
