refactor: migrate repository to foundry-template (#6)
This commit migrates the repo to our foundry template, which ensures we have consistent tooling across smart contract repositories that are maintained by Vac. This removes all hardhat related files and workflows and replaces them with more perfomant foundry workflows. It also sets up tests, CI and linting.

## Protocol properties and invariants
|
||||
|
||||
Below is a list of all documented properties and invariants of this project that must hold true.
|
||||
|
||||
- **Property** - Describes the property of the project / protocol that should ultimately be tested and formaly verified.
|
||||
- **Type** - Properties are split into 5 main types: **Valid State**, **State Transition**, **Variable Transition**,
|
||||
**High-Level Property**, **Unit Test**
|
||||
- **Risk** - One of **High**, **Medium** and **Low**, depending on the property's risk factor

||||
|
||||
| **Property** | **Type** | **Risk** | **Tested** |

|
||||
|
||||
A Foundry-based template for developing Solidity smart contracts, with sensible defaults.
|
||||
|
||||
This is a fork of [PaulRBerg's template](https://github.com/PaulRBerg/foundry-template) and adjusted to Vac's smart
|
||||
contracts unit's needs. See [Upstream differences](#upstream-differences) to learn more about how this template differs
|
||||
from Paul's.
|
||||
|
||||
## What's Inside
|
||||
|
||||
- [Forge](https://github.com/foundry-rs/foundry/blob/master/forge): compile, test, fuzz, format, and deploy smart
|
||||
contracts
|
||||
- [Forge Std](https://github.com/foundry-rs/forge-std): collection of helpful contracts and cheatcodes for testing
|
||||
- [Solhint Community](https://github.com/solhint-community/solhint-community): linter for Solidity code
|
||||
|
||||
## Getting Started
|
||||
|
||||
Click the [`Use this template`](https://github.com/vacp2p/foundry-template/generate) button at the top of the page to
|
||||
create a new repository with this repo as the initial state.
|
||||
|
||||
Or, if you prefer to install the template manually:
|
||||
|
||||
```sh
|
||||
$ mkdir my-project
|
||||
$ cd my-project
|
||||
$ forge init --template vacp2p/foundry-template
|
||||
$ pnpm install # install Solhint, Prettier, and other Node.js deps
|
||||
```
|
||||
|
||||
If this is your first time with Foundry, check out the
|
||||
[installation](https://github.com/foundry-rs/foundry#installation) instructions.
|
||||
|
||||
## Features
|
||||
|
||||
This template builds upon the frameworks and libraries mentioned above, so for details about their specific features,
|
||||
please consult their respective documentation.
|
||||
|
||||
For example, if you're interested in exploring Foundry in more detail, you should look at the
|
||||
[Foundry Book](https://book.getfoundry.sh/). In particular, you may be interested in reading the
|
||||
[Writing Tests](https://book.getfoundry.sh/forge/writing-tests.html) tutorial.
|
||||
|
||||
### Upstream differences
|
||||
|
||||
As mentioned above, this template is a fork with adjustments specific to the needs of Vac's smart contract service unit.
|
||||
These differences are:
|
||||
|
||||
- **Removal of [PRBTest](https://github.com/PaulRBerg/prb-test)** - In an attempt to keep dependence on third-party code
|
||||
low, we've decided to remove this library as a standard dependency of every project within Vac. If we do see a need
|
||||
for it, we might bring it back in the future.
|
||||
- \*\*`PROPERTIES.md` - For invariant testing and formal verification, we've introduced a `PROPERTIES.md` to document
|
||||
all protocol properties that must hold true.
|
||||
|
||||
### Sensible Defaults
|
||||
|
||||
This template comes with a set of sensible default configurations for you to use. These defaults can be found in the
|
||||
following files:
|
||||
|
||||
```text
|
||||
├── .editorconfig
|
||||
├── .gitignore
|
||||
├── .prettierignore
|
||||
├── .prettierrc.yml
|
||||
├── .solhint.json
|
||||
├── foundry.toml
|
||||
├── remappings.txt
|
||||
└── slither.config.json
|
||||
```
|
||||
|
||||
### VSCode Integration
|
||||
|
||||
This template is IDE agnostic, but for the best user experience, you may want to use it in VSCode alongside Nomic
|
||||
Foundation's [Solidity extension](https://marketplace.visualstudio.com/items?itemName=NomicFoundation.hardhat-solidity).
|
||||
|
||||
For guidance on how to integrate a Foundry project in VSCode, please refer to this
|
||||
[guide](https://book.getfoundry.sh/config/vscode).
|
||||
|
||||
### GitHub Actions
|
||||
|
||||
This template comes with GitHub Actions pre-configured. Your contracts will be linted and tested on every push and pull
|
||||
request made to the `main` branch.
|
||||
|
||||
You can edit the CI script in [.github/workflows/ci.yml](./.github/workflows/ci.yml).
|
||||
|
||||
## Writing Tests
|
||||
|
||||
If you would like to view the logs in the terminal output you can add the `-vvv` flag and use
|
||||
[console.log](https://book.getfoundry.sh/faq?highlight=console.log#how-do-i-use-consolelog).
|
||||
|
||||
This template comes with an example test contract [Foo.t.sol](./test/Foo.t.sol)
|
||||
|
||||
## Usage
|
||||
|
||||
This is a list of the most frequently needed commands.
|
||||
|
||||
### Build
|
||||
|
||||
Build the contracts:
|
||||
|
||||
```sh
|
||||
$ forge build
|
||||
```
|
||||
|
||||
### Clean
|
||||
|
||||
Delete the build artifacts and cache directories:
|
||||
|
||||
```sh
|
||||
$ forge clean
|
||||
```
|
||||
|
||||
### Compile
|
||||
|
||||
Compile the contracts:
|
||||
|
||||
```sh
|
||||
$ forge build
|
||||
```
|
||||
|
||||
### Coverage
|
||||
|
||||
Get a test coverage report:
|
||||
|
||||
```sh
|
||||
$ forge coverage
|
||||
```
|
||||
|
||||
### Deploy
|
||||
|
||||
Deploy to Anvil:
|
||||
|
||||
```sh
|
||||
$ forge script script/Deploy.s.sol --broadcast --fork-url http://localhost:8545
|
||||
```
|
||||
|
||||
For this script to work, you need to have a `MNEMONIC` environment variable set to a valid
|
||||
[BIP39 mnemonic](https://iancoleman.io/bip39/).
|
||||
|
||||
For instructions on how to deploy to a testnet or mainnet, check out the
|
||||
[Solidity Scripting](https://book.getfoundry.sh/tutorials/solidity-scripting.html) tutorial.
|
||||
|
||||
### Format
|
||||
|
||||
Format the contracts:
|
||||
|
||||
```sh
|
||||
$ forge fmt
|
||||
```
|
||||
|
||||
### Gas Usage
|
||||
|
||||
Get a gas report:
|
||||
|
||||
```sh
|
||||
$ forge test --gas-report
|
||||
```
|
||||
|
||||
### Lint
|
||||
|
||||
Lint the contracts:
|
||||
|
||||
```sh
|
||||
$ pnpm lint
|
||||
```
|
||||
|
||||
### Test
|
||||
|
||||
Run the tests:
|
||||
|
||||
```sh
|
||||
$ forge test
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
1. Foundry uses [git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules) to manage dependencies. For
|
||||
detailed instructions on working with dependencies, please refer to the
|
||||
[guide](https://book.getfoundry.sh/projects/dependencies.html) in the book
|
||||
2. You don't have to create a `.env` file, but filling in the environment variables may be useful when debugging and
|
||||
testing against a fork.
