Overview

FunC is minimalist, domain-specific, functional-style language designed for writing low-level TON smart contracts, tightly bound to the TVM model.

Here is a simple example of a method for sending money written in FunC:

() send_money(slice address, int amount) impure inline {
    var msg = begin_cell()
        .store_uint(0x10, 6) ;; nobounce
        .store_slice(address)
        .store_coins(amount)
        .end_cell();

    send_raw_message(msg, 64);
}

The compiler converts FunC programs into Fift assembler code, generating the corresponding bytecode for the TON Virtual Machine.

Developers and engineers can use its bytecode, which is structured as a tree of cells like all data in the TON Blockchain, to create smart contracts or run it on a local instance of the TVM.
