Multi-Sol-Verifier
Multi-sol-verifier is an NPM package to verify the Solidity smart contracts on Etherscan & Bscscan. It works as a CLI tool and can be used inside the js file too. This project is highly derived from npm package sol-verifier.
Install
As a dependency, to use inside a file:
npm install --save multi-sol-verifier
As a development dependency, to use it as <project_root>/node_modules/.bin/sol-verifier:
npm install --save-dev multi-sol-verifier
As a global npm module, to use sol-verifier as an executable:
npm install -g multi-sol-verifier
How to use
By requiring in file
A request object will be passed to verify contract. See below: (Make sure keys of request object will be always same)
const verifier = require('multi-sol-verifier');
var data = {
key: 'etherscan-api-key', // Etherscan API key (required)
path : '/path/to/contract/contractName.sol', // Contract file path(required)
contractAddress: '0x123456789.......', // Contract address (required)
network : 'mainnet/ropsten/rinkeby/kovan', // Ethereum network used (required)
contractName: 'contractName' // Contract name, only if contract file has more than one contracts
cvalues : [constructor, values, in, array], // constructor values in array, only if contract has constructor
evmVersion: 'istanbul', // See valid options: https://solidity.readthedocs.io/en/latest/using-the-compiler.html#target-options (optional, default compiler-default)
runs: 200, // Optimizer Runs (optional, default 200)
licenseType: 1, // Valid codes 1-12, see https://etherscan.io/contract-license-types (optional, default 1=No License)
optimizationFlag: false // Set `true` to enable optimization (default false)
};
await verifier.verifyContract(data);
Parameters not applicable can be ignored.
Points to remember
- Add specific version with
^in your contract pragma. Version should be same as the compiler version used while contract deployment. - This doesn't provide support for libraries.
- Works for solidity version
> 0.4.11. - The Etherscan API that this module uses is in BETA state.
- Maximum time for processing verification request is 30 seconds. If request timed out, check final result on Etherscan itself.
