VSOPEN

VSOPEN is a commandline tool that can be used to download smart contract sourcecode from Blockchain explorers like Etherscan, and further set it up as project in VSCode IDE.

Prerequisite

• Node.Js. You need to have Node and NPM installed on your system to use this tool. It is recommended to have Node version greater than v16.

  $ node --version
    v16.14.2

• API key. Blockchain explorers will require user to register API keys to access their API. For example, you can get your Etherscan API key from this link.

• (Optional) VSCode. If you want to import downloaded source code into VSCode, you may download and install the IDE from its official release. Here are some basic configurations for VSCode:

  • Install 'code' command into your PATH.
  • Install the 'solidity' language extension for VSCode.

Usage

1. Installation.

   $ npm install -g wiw-vsopen2@latest

   $ vsopen config

   Example config for Ethereum mainnet:

   {
     "chain": "eth"
     "apikey": "YOUR_API_KEY"
     "url": "https://api.etherscan.io/api"
   }

   API url for blockchain explorers:

   eth-mainnet: https://api.etherscan.io/api
   polygon-mainnet: https://api.polygonscan.com/api
   bnb-mainnet: https://api.bscscan.com/api

3. Download source code for verified smart contract.

   $ vsopen get <contract_address> -c <chain>

4. (Optional) Import source code folder into VSCode.

   $ code ./
