Since v0.56.0 Remix IDE comes with a built-in verification plugin that allows you to verify your contracts on multiple verifiers. To verify your contracts on Remix:
  • Turn on the plugin “CONTRACT VERIFICATION” from the plugin manager.
  • On the File Explorer, select and compile the contract you want to verify.
  • On the Contract Verification plugin, select the Contract Name, Chain, and input the contract address. Add constructor arguments if needed.
  • Click “Verify”. You can see the process on the “Receipts” tab.
You can find more information about the plugin in the Remix documentation.
