Is there a standard way to declare an ABI and then call a contract address using that ABI?
I didn’t see any mention of this in the documentation so apologies if I missed something!

Found my answer here:

By importing the ContractA ABI, you can make a call to a contract supporting the ContractA interface.
```auto
// ./contract_b.sw
contract;
use contract_a::ContractA;
abi ContractB {
fn make_call();
}
const contract_id = 0x79fa8779bed2f36c3581d01c79df8da45eee09fac1fd76a5a656e16326317ef0;
impl ContractB for Contract {
fn make_call() {
let x = abi(ContractA, contract_id);
let return_value = x.receive(true, 3); // will be 45
}
}
```
