How to verify with Hardhat or Truffle a smart contract using OpenZeppelin Contracts

For a complete list of resources regarding verification visit How to verify a contract on Etherscan/BscScan/PolygonScan. The recommended way to verify a smart contract inheriting from OpenZeppelin Contracts is as a "multi-file" contract (corresponding to the Standard-Json-Input compiler type on Etherscan). It is easier to read, imports are maintained, licenses are maintained. Verified using Hardhat Verified using Truffle Hardhat Hardhat has an Etherscan plugin: Hardhat Etherscan plugin N…

Make sure to read this post before asking a question about verification. If your issue is not addressed here, just leave a comment below. If you want to pay someone to do the verification for you, create a post in Developer Wanted. This guide applies to all Etherscan instances, including all of the following as well as their testnet explorers: etherscan.io (Ethereum) bscscan.com (Binance Smart Chain) polygonscan.com (Polygon) snowtrace.io (Avalanche) Recommendations Practice in testnet Be…

Verify ERC20 token on Etherscan that was deployed through Remix: Step by Step Guide

At the previous tutorial: Create an ERC20 using Remix, without writing Solidity, we have learned how to deploy contracts with the Remix, and now in this tutorial, we will learn how to verify the deployed contracts by a single file. Cause many people deploy contracts by the Remix, so in this part, we will use the plugin FLATTENER in the Remix to help us to package all contracts file into a single file to verify. In short, all steps are: Compile contract Flatten contract Copy the whole code to…
