Waku's RLNv2 contracts, which include -
- LazyIMT, which allows the root of the chain to be accessible on-chain.


## 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

## 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
```

#### Fixing linting issues

For any errors in solidity files, run `forge fmt`. For errors in any other file type, run `pnpm prettier:write`.

### 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.
