Quick start 🚀

Run the command in terminal to create a new project and follow the on-screen instructions:

npm create ton@latest

Overview

Blueprint is an all-in-one development environment designed to enhance the process of creating, testing, and deploying smart contracts on TON blockchain using FunC and Tact languages

Core features

• Create a development environment from template - npm create ton@latest
• Streamlined workflow for building, testing and deploying smart contracts
• Dead simple deployment to mainnet/testnet using your favorite wallet (eg. Tonkeeper)
• Blazing fast testing of multiple smart contracts in an isolated blockchain running in-process

Tech stack

1. Compiling FunC with https://github.com/ton-community/func-js
2. Compiling Tact with https://github.com/tact-lang/tact
3. Testing smart contracts with https://github.com/ton-org/sandbox
4. Deploying smart contracts with TON Connect 2, Tonhub wallet or a ton:// deeplink

Requirements

• Node.js with a recent version like v18. Version can be verified with node -v
• IDE with TON support:
  • Visual Studio Code with the FunC plugin
  • IntelliJ IDEA with the TON Development plugin

Features overview

Project creation

1. Run and follow the on-screen instructions:   npm create ton@latest   or   npx create-ton@latest
2. From the project directory run   npm/yarn install   to install dependencies

Directory structure

• contracts/ - Source code in FunC or Tact for all smart contracts and their imports
• wrappers/ - TypeScript interface classes for all contracts (implementing Contract from @ton/core)
  • include message [de]serialization primitives, getter wrappers and compilation functions
  • used by the test suite and client code to interact with the contracts from TypeScript
• tests/ - TypeScript test suite for all contracts (relying on Sandbox for in-process tests)
• scripts/ - Deployment scripts to mainnet/testnet and other scripts interacting with live contracts
• build/ - Compilation artifacts created here after running a build command

Building contracts

1. You need a compilation script in wrappers/<CONTRACT>.compile.ts - example
2. Run interactive:    npx blueprint build   or   yarn blueprint build
3. Non-interactive:   npx/yarn blueprint build <CONTRACT>   OR build all contracts   yarn blueprint build --all
   • Example: yarn blueprint build counter
4. Build results are generated in build/<CONTRACT>.compiled.json
5. Tact generated files are located in build/<CONTRACT> directory

Running the test suites

1. Run in terminal:   npx blueprint test   or   yarn blueprint test
2. Alternative method:   npm test   or   yarn test
3. You can specify test file to run:   npm/yarn test <CONTRACT>
   • Example: yarn test counter

Learn more about writing tests from the Sandbox's documentation - here.

Deploying contracts

1. You need a deployment script in scripts/deploy<CONTRACT>.ts - example
2. Run interactive:    npx blueprint run   or   yarn blueprint run
3. Non-interactive:   npx/yarn blueprint run deploy<CONTRACT> --<NETWORK> --<DEPLOY_METHOD>
   • Example: yarn blueprint run deployCounter --mainnet --tonconnect

Custom scripts

1. Custom scripts should be located in scripts folder
2. Script file must have exported function run

export async function run(provider: NetworkProvider) {
  // 
}

3. Script can be run using npx/yarn blueprint run <SCRIPT> command

Updating FunC version

FunC version can be updated using npx/yarn blueprint set func command

Help and additional commands

Run in terminal:   npx blueprint help   or   yarn blueprint help

Contract development

Before developing, make sure that your current working directory is located in the root of the project created using npm create ton@latest

Creating contracts

1. Run interactive:    npx blueprint create   or   yarn blueprint create
2. Non-interactive:   npx/yarn blueprint create <CONTRACT> --type <TYPE> (type can be func-empty, func-counter, tact-empty, tact-counter)
   • Example: yarn blueprint create MyNewContract --type func-empty

Writing contract code

FunC

1. Implement the standalone FunC root contract in contracts/<CONTRACT>.fc
2. Implement shared FunC imports (if breaking code to multiple files) in contracts/imports/*.fc
3. Implement wrapper TypeScript class in wrappers/<CONTRACT>.ts to encode messages and decode getters

Tact

1. Implement tact contract in contracts/<CONTRACT>.tact
2. Wrappers will be automatically generated in build/<CONTRACT>/tact_<CONTRACT>.ts

Testing contracts

1. Implement TypeScript tests in tests/<CONTRACT>.spec.ts
2. Rely on the wrapper TypeScript class from wrappers/<CONTRACT>.ts to interact with the contract

Learn more about writing tests from the Sandbox's documentation - here.

Configuration

A config may be created in order to control some of blueprint's features. If a config is needed, create a blueprint.config.ts file in the root of your project with something like this:

import { Config } from '@ton/blueprint';

export const config: Config = {
    // config contents
};

It is important that the config is exported, is named config, and is not default exported.

Config's features are explained below.

Plugins

Blueprint has a plugin system to allow the community to develop their own additions for the ecosystem without the need to change blueprint's code.

In order to use plugins, add a plugins array to your config:

import { Config } from '@ton/blueprint';
import { ScaffoldPlugin } from 'blueprint-scaffold';

export const config: Config = {
    plugins: [new ScaffoldPlugin()],
};

(This example shows how to add the scaffold plugin)

Here are some of the plugins developed by the community:

• scaffold - allows developers to quickly create a simple dapp automatically using the wrappers' code

Custom network

A custom network may be specified by using the --custom flags, which you can read about by running blueprint help run, but it can be tiresome to use these at all times. Instead, to specify a custom network to always be used (unless --custom flags are present), add a network object to your config:

import { Config } from '@ton/blueprint';

export const config: Config = {
    network: {
        endpoint: 'https://toncenter.com/api/v2/jsonRPC',
        type: 'mainnet',
        version: 'v2',
        key: 'YOUR_API_KEY',
    },
};

The above config parameters are equivalent to the arguments in the following command:

npx blueprint run --custom https://toncenter.com/api/v2/jsonRPC --custom-version v2 --custom-type mainnet --custom-key YOUR_API_KEY

Properties of the network object have the same semantics as the --custom flags with respective names (see blueprint help run).

You can also use custom network to verify contracts, like so:

npx blueprint verify --custom https://toncenter.com/api/v2/jsonRPC --custom-version v2 --custom-type mainnet --custom-key YOUR_API_KEY

(or similarly using the config), however custom type MUST be specified as either mainnet or testnet when verifying.
