I have had some issues verifying my contract on BSCscan. I’m relatively new to this. **Here is my code followed by the error:** pragma solidity ^0.8.0; import “[https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol)”; contract CaribCoin is ERC20 { constructor(uint256 initialSupply) public ERC20(“CaribCoin”, “CARIB”) { \_mint(msg.sender, initialSupply); } } Warning: SPDX license identifier not provided in source file.

Hi @Lemon_Juice welcome to the Open Zeppelin forums. Please follow the tutorial at [OpenZeppelin Upgrades: Step by Step Tutorial for Hardhat](https://forum.openzeppelin.com/t/openzeppelin-upgrades-step-by-step-tutorial-for-hardhat/3580) to get started. Your verification problem is likely an environment issue. Are you using Remix, Hardhat, or Truffle? ---

I'm using Remix.

Hi, welcome! 👋 Sorry, I am not familiar with the BSC-Chain, maybe you should ask for help in their forum: [Home | Binance Chain Forum](https://community.binance.org/) And they have a documentation about how to verify contracts, maybe you can have a look at it: - [Truffle Verify - Binance Chain Docs](https://docs.binance.org/smart-chain/developer/deploy/truffle-verify.html) - [HardHat Verify - Binance Chain Docs](https://docs.binance.org/smart-chain/developer/deploy/hardhat-verify.html) And your contract has been verified. ---

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.
