Hi,

i have copied the code from cyfrin course repo and still the code does not compile with the below error.

Can you share DecentralizedStableCoin contract?

[thebraveman17]

You need to pass the constructor argument (address initialOwner) to the Ownable contract.

For example:

contract DecentralizedStableCoin is ERC20Burnable, Ownable(address(1))

ran into the same problem, this solution worked perfectly.

Hello @helloram007, Please do as suggested by @thebraveman17 and let us know if the issue gets resolved.

I had that i have pass something to Ownable, but Patricks code does not have that, and when i inherited Ownable it didnot thrw any error, so left it. i will not pass the param and see if it works. Thanks

It is not compulsory your code is exactly like Patrick's code. Most likely, in some parts of the codebase, your code will have to be different from his because the tools we use get updated from time to time, and some stuff might have changed, which you now need to account for to make your code work appropriately.

To follow along with the course, you need to install version 4.8.3 which can be done by

forge install openzeppelin/openzeppelin-contracts@v4.8.3 --no-commit

instead of

forge install openzeppelin/openzeppelin-contracts --no-commit

And then in the DecentralizedStableCoin.sol write the constructor like this

constructor() ERC20("DecentralizedStableCoin", "DSC") {}

Yes , its work.

Good job.
