Your contract must implement a contract interface in order to be imported. In this case, we’re borrowing a contract that implements the NonFungibleToken contract interface.
You can only access fields/functions present in the contract interface.
cadence
import NonFungibleToken from 0x1d7e57aa55817448
pub fun main(contractAddress: Address, contractName: String): UInt64 {
let contract = getAccount(contractAddress).contracts.borrow<&NonFungibleToken>(name: contractName)
?? panic("This contract does not exist in this account.")
return contract.totalSupply
}
