# @ethereum-waffle/chai

A sweet set of chai matchers for your blockchain testing needs.

## Installation

In the current version of waffle (v2.x.x) you will install this package as a dependency of the main waffle package - `ethereum-waffle`.

```
yarn add --dev ethereum-waffle
npm install --save-dev ethereum-waffle
```

If you want to use this package directly please install it via:
```
yarn add --dev @ethereum-waffle/chai
npm install --save-dev @ethereum-waffle/chai
```

## Usage
```ts
import { expect, use } from "chai";
import { waffleChai } from "@ethereum-waffle/chai";
import { bigNumberify } from "ethers/utils";

use(chaiAsPromised);

expect(bigNumberify("6")).to.be.gt(0);
```

## Feature overview

**NOTE**: You do not need to use this package directly. You can install it through the main package (`ethereum-waffle`) and use it instead.
