Smart contract verification library.

Makes it possible to verify some contract code against a deployed contract address.

Originally inspired by Shawn's article:

[Verify Ethereum Contracts Using Web3.js and Solc](https://www.shawntabrizi.com/ethereum/verify-ethereum-contracts-using-web3-js-and-solc/)

# Usage example

```js

const { compileExtractCompare } = require("smart-contract-verifier");

const Web3 = require("web3");

const web3 = new Web3(

  new Web3.providers.HttpProvider(process.env.RPC_PROVIDER)

);

const solcVersion = "v0.4.16+commit.d7661dd9";

const contractName = "LinkToken";

const contractFilename = "LinkToken.sol";

const contractAddress = "0x514910771AF9Ca656af840dff83E8264EcF986CA";

// assuming the LinkToken.sol file is on the file system

const contractPath = "./" + contractFilename;

const sources = { [contractFilename]: fs.readFileSync(contractPath, "utf8") };

compileExtractCompare(

  web3,

  sources,

  solcVersion,

  contractName,

  contractFilename,

  contractAddress

).then((matching) => console.log(matching));

```
