Hi @pageone,

What is the error that you get when deploying on mainnet? Can you share the output from your migration?

No error message. It deployed a normal contract ,not Upgrades.

Hi @pageone,

deployProxy will deploy

  1. implementation contract
  2. ProxyAdmin contract
  3. proxy contract

https://docs.openzeppelin.com/upgrades-plugins/1.x/#how-plugins-work

Truffle will also deploy a Migrations contract.

Can you advise which contracts were deployed and the output of your migrations script?
