A high-level language FunC is used to program smart contracts on TON.

FunC is a domain-specific, C-like, statically typed language. Here is a simple example method for sending money written in FunC:

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

send_raw_message(msg, 64);

FunC programs are compiled into Fift assembler code, which generates corresponding bytecode for the TON Virtual Machine.

Further this bytecode (actually a tree of cells, like any other data in TON Blockchain) can be used for creating smart contracts in the blockchain or can be run on a local instance of TVM.

You can find more information about FunC in the DOCUMENTATION section.


FunC documentation was initially written by @akifoq.


Compile with JS

Most convenient and quick way to begin develop and compile smart contracts is using Blueprint framework. Read more in Blueprint section.

Compile with original binaries

If you want to use native TON compiler FunC locally you need binaries setup on your machine. FunC compiler binaries for Windows, MacOS (Intel/M1), and Ubuntu can be downloaded from:


At the same time you can always make binaries from sources like:
FunC compiler source code (read how to compile a FunC compiler from sources).

Participating in contests is a great way to learn FunC.

You can also study previous competitions for learning purposes:

Smart contract examples

Standard basic smart contracts like wallets, electors (manages validation on TON), multi-signature wallets, etc. can be a reference when studying.
