Hello

What is constructor data argument in proxy contract? And how to calculate it. Anyone one who can explain it to me .

There are no constructors in proxy contracts

I mean for upgradeable proxy contract.They have 3 constructor arguments

Mm I don't think so. Proxys don't have constructors, only init functions. Which is called right after the deployment

Pls check this proxy contract. It has 3 constructor arguments

Aah you meant the proxy itself, not implementation behind it

Yea I mean the proxy . I want to know how I calculate that data argument

Its straightforward, _admin will be the owner address, _implementation is the address of actual contract and _data is the calldata used to call the implementation initially (not necessary, can keep it 0)

Although you don't have to provide them explicitly while using the deployProxy method on truffle/hardhat

Thanks for the help I got it now.
