chore: introduce SNT V2 (#1)
This introduces an SNT V2 token implementation. It inherits from `MiniMeToken` and also comes with an `SNTTestnetController` that can be used on test networks for allowing minting of tokens by anyone. This makes the token controller more general and introduces an `open` property to enable/disable the faucet. Also adds a `destroyTokens()` function for completeness' sake.

|
||||
|
||||
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)
|
||||
This is the second iteration of [Status Network Token](https://github.com/status-im/status-network-token). The original
|
||||
version of the token uses a lot of legacy code. This repository implements a more modern version based on our
|
||||
[MiniMeToken](https://github.com/vacp2p/minime) fork.
