Done!

This is a plugin to verify contract, maybe next time, you can have a try:

> ✅ Verify your smart contracts on Etherscan from the Truffle CLI

I just use this package: [truffle-flattener](https://www.npmjs.com/package/truffle-flattener), flatten all dependencies contracts into a contract, and then verify it on the etherscan, select compile version is `0.6.2`, select `Optimization Enabled` and then verified was done.

It depends on you.  
There are some articles wrote by `abcoathup`, maybe it can help you.
