Environment setup

To start working with Tolk, you need a development environment.

We recommend using Blueprint, a tool for writing, testing, and deploying smart contracts on TON.

Create a new TON project​

Prerequisite: Node.js v16 or higher

  1. Create a new TON project: 
    npm create ton@latest
  2. Enter any project name and select "A simple counter contract (Tolk)" when prompted by Blueprint.

Project structure​

Here's a quick look at the typical project layout:

my-first-contract/
├── build/             # Compiled smart contract bytecode
├── contracts/         # Smart contract sources (e.g., counter.tolk)
├── scripts/           # TypeScript deployment scripts
├── tests/             # TypeScript tests
├── wrappers/          # TypeScript wrappers for contracts

Build the project​

npx blueprint build
# or
yarn blueprint build

Blueprint compiles the contract and displays the resulting bytecode, along with its hash. The output is saved in the build/ directory.

Run tests​

npx blueprint test
# or
yarn blueprint test

This runs unit tests from the tests/ directory.

Deploy or run a script​

npx blueprint run
# or
yarn blueprint run

Use this command to deploy your contract to Mainnet, Testnet, or MyLocalTon.

IDE support​

Tolk is supported in IntelliJ-based IDEs using the TON plugin and in Visual Studio Code through the TON extension.
