Assalamualaikum,
I am new to blockchain. So I was thinking of deploying a smart contract as rest api, and use it in my another smart contract. Is it possible? I know oracle helps to fetch data but can it help interacting two deployed contracts? Thank in advance.
You can define an interface of the target contract in the source contract. Example:
TargetContract, deployed on the 0x123 address:
pragma solidity ^0.8;
contract TargetContract {
function foo() external pure returns (bool) {
return true;
}
}
SourceContract, pointing to the 0x123 TargetContract
pragma solidity ^0.8;
interface ITargetContract {
function foo() external returns (bool);
}
contract SourceContract {
function baz() external {
ITargetContract targetContract = ITargetContract(address(0x123));
bool returnedValue = targetContract.foo();
}
}
