# A template for EVM-based smart contract development

## How to use it?

### Compile your contracts

```bash
pnpm compile
```

### Test your contracts

There are 2 flavors of tests

1. Using hardhat

```bash
pnpm test
```

2. Using foundry

```bash
forge test
```

This assumes you have `forge` installed and that you added forge-std in via the following command

```bash
git clone --recursive https://github.com/foundry-rs/forge-std.git lib/forge-std
```

> (You can also add it as a submodule if you prefer, just remove the `lib/forge-std` line in .gitignore first)

### watch for changes and rebuild automatically

```bash
pnpm compile:watch
```

### deploy your contract

- on localhost

This assumes you have a local node running: `pnpm local_node`

```bash
pnpm run deploy localhost
```

- on a network of your choice

Just make sure you have your .env.local setup, see [.env](.env)

```bash
pnpm run deploy
```

### execute scripts

```bash
pnpm execute scripts/setMessage.ts
```

or if you want to execute in a forked environment :

```bash
pnpm fork:execute scripts/setMessage.ts "Hello world"
```

### zellij

[zellij](https://zellij.dev/) is a useful multiplexer (think tmux) for which we have included a [layout file](./zellij.kdl) to get started

Once installed simply run the following to get a local in-memory Ethereum node running along with the tests

```bash
pnpm start
```

if you want to try Zellij without installing it, try this :

```bash
bash <(curl -L zellij.dev/launch) --layout zellij.kdl
```

In the shell in the upper pane, you execute the script as mentioned above

```bash
pnpm execute localhost scripts/setMessage.ts "Hello everyone"
```

## Initial Setup

You need to have these installed

- [nodejs](https://nodejs.org/en)

- [pnpm](https://pnpm.io/)

```bash
npm i -g pnpm
```

Then you need to install the local dependencies with the following command:

```bash
pnpm i
```

We also recommend installing [Zellij](https://zellij.dev/) to have your dev env setup in one go via `pnpm start`
