Interfaces

[GaneshDonikena]

Hi everyone!,

To interact with a contract, we need ABI and address.

we have only abi after compiling below line:

import "@chainlink/contracts/src/v0.8/interfaces/VRFCoordinatorV2Interface.sol";

Now how can I find the address of VRFCoordinatorV2Interface?. Please help me.

i_vrfCoordinator = VRFCoordinatorV2Interface(vrfCoordinatorV2);

What is the address required for? For the course you only need the address of the CoordinatorV2Mock contracts you deploy.

This is VRFCoordinatorV2Mock though (sorry if I am missing something). The OP wants to know about the interface for some reason.

[DorianDaSilva]

@krakxn Right but it seems to me that VRFCoordinatorV2Interface(vrfCoordinatorV2); is calling the vrfCoordinatorV2 address as its parameter hence the link to the doc to get the right vrf address for testnet. (Maybe I am confused)
