> ⏬🚀 Fetch the most up-to-date sources of verified Smart Contracts (including proxy implementations) from Etherscan in seconds!

## Usage

### CLI

- Fetch the sources of a contract from an address and save it to `sources/ContractName/`:

```bash
npx etherscan-src 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984
```

- Note that if a standard proxy is detected, the proxy's implementation sources will be fetched instead:

```bash
npx etherscan-src 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9
```

- You can optionally provide a `target` directory path, an Etherscan `apiKey` (to bypass the default query rate limit), or specify a `network` on which to query the Smart Contract's source code (by [name or chainId, decimal or hexadecimal](./src/constants/chainIds.ts)):

```bash
npx etherscan-src --target sources/uniswap/ \
    --apiKey ... \
    --network polygon \
    0xb33EaAd8d922B1083446DC23f610c2567fB5180f
```

## Install

```bash
npm install etherscan-src
```

```bash
yarn add etherscan-src
```
