You can use each submodule individually. Click the module below to get more details.

• Tonlib - use external Tonlib shared library to communicate with TON blockchain.
• SmartContract - create and deploy custom and predefined smart-contracts.
• Cell - create, read and manipulate Bag of Cells.
• BitString - construct bit-strings.
• Address - create and parse TON wallet addresses.
• Mnemonic - helpful methods for generating deterministic keys for TON blockchain.
• Emulator - wrapper for using with external precompiled emulator shared library.
• Liteclient - wrapper for using with external precompiled lite-client binary.
• Utils - create private and public keys, convert data, etc.
