TON project template (RFC)

Starter template for a new TON project - FunC contracts, unit tests, compilation and deployment scripts.

This repo is a work in progress and is subject to change

Layout

• contracts - contains the source code of all the smart contracts of the project and their dependencies.
• wrappers - contains the wrapper classes (implementing Contract from ton-core) for the contracts, including any [de]serialization primitives and compilation functions.
• tests - tests for the contracts. Would typically use the wrappers.
• scripts - contains scripts used by the project, mainly the deployment scripts.

We ask the community to provide any comments on this layout, the wanted/required changes, or even suggestions for entirely different project structures and/or tool concepts.

PRs are welcome!

Repo contents / tech stack

1. Compiling FunC - https://github.com/ton-community/func-js
2. Testing TON smart contracts - https://github.com/ton-community/sandbox/
3. Deployment of contracts is supported with TON Connect 2, Tonhub wallet or via a direct ton:// deeplink

How to use

• Clone this repo
• Run yarn install

Building a contract

1. Interactively
   1. Run yarn blueprint build
   2. Choose the contract you'd like to build
2. Non-interactively
   1. Run yarn blueprint build <CONTRACT>
   2. example: yarn blueprint build pingpong

Deploying a contract

1. Interactively
   1. Run yarn blueprint run
   2. Choose the contract you'd like to deploy
   3. Choose whether you're deploying on mainnet or testnet
   4. Choose how to deploy:
      1. With a TON Connect compatible wallet
      2. A ton:// deep link / QR code
      3. Tonhub wallet
   5. Deploy the contract
2. Non-interactively
   1. Run yarn blueprint run <CONTRACT> --<NETWORK> --<DEPLOY_METHOD>
   2. example: yarn blueprint run pingpong --mainnet --tonconnect

Testing

1. Run yarn test

Adding your own contract

1. Run yarn blueprint create <CONTRACT>
2. example: yarn blueprint create MyContract

• Write code

  • FunC contracts are located in contracts/*.fc
    • Standalone root contracts are located in contracts/*.fc
    • Shared imports (when breaking code to multiple files) are in contracts/imports/*.fc
  • Tests in TypeScript are located in test/*.spec.ts
  • Wrapper classes for interacting with the contract are located in wrappers/*.ts
  • Any scripts (including deployers) are located in scripts/*.ts

• Build

  • Builder configs are located in wrappers/*.compile.ts
  • In the root repo dir, run in terminal yarn blueprint build
  • Compilation errors will appear on screen, if applicable
  • Resulting build artifacts include:
    • build/*.compiled.json - the binary code cell of the compiled contract (for deployment). Saved in a hex format within a json file to support webapp imports

• Test

  • In the root repo dir, run in terminal yarn test
  • Don't forget to build (or rebuild) before running tests
  • Tests are running inside Node.js by running TVM in web-assembly using sandbox

• Deploy

  • Run yarn blueprint run <deployscript>
  • Contracts will be rebuilt on each execution
  • Follow the on-screen instructions of the deploy script
