Interact with contracts implemented in Solidity: A Guide
In the world of Ethereum, contract implementation is a fundamental aspect of the construction of decentralized applications (DApps). Library, there are cases in which we need to omit Solidity,
Direct Calls Vs. Web Library
Before immersing yourselves in the issue of implementing with
* Direct calls
:
* Example:
`
Callfunction contract {
Myfunction Function () Public Returns (Chain Memory) {
Return Callcontract (“Othercontract”, “Myfunction”);
}
}
`
* Web Library :
Interact With Contracts Implemented
Library; Here are some examples:
1. Direct Called
You can call another contract addressly when
`Solidity
// hire and
Pragma Solidity ^0.8.0;
Callfunction contract {
// Function to Interact With Another Contract
Myfunction Function () Public Returns (Chain Memory) {
Return Callcontract ("Othercontract", "Myfunction");
}
}
2. Using Key Assembly Words
Messages:
`Solidity
// hire and
Pragma Solidity ^0.8.0;
Callfunction contract {
// Function to Interact With Another Contract
Myfunction Function () Public Returns (Chain Memory) {
// SEND A MESSAGE TO ANOTHER CONTRACT
assembly
Leave Msg = Mjmpack ("Otrocontract", "Myfunction", 0)
Call (0, Msg, 0)
}
}
In this example, we use the other contract.
Example Use Case
The Contract and Contract B. In Contract A, we define a ‘Myfunction’ that returns a Chain Value. Then we call this function of another contract using direct calls or key Assembly Words:
`Solidity
// hire and
Pragma Solidity ^0.8.0;
Callfunction contract {
// Function to Interact With Another Contract
Myfunction Function () Public Returns (Chain Memory) {
Return "Hello, World!";
}
}
Directly or use key assembly words to send a message to contract b:
Solidity
// contract b
Pragma Solidity ^0.8.0;
Callfunction contract {
// Function to Interact With Another Contract
Myfunction Function () Public Returns (Chain Memory) {
Return "Hello, World!";
}
}
Following these guidelines and examples, it can now interact with contracts implemented in solidity without taking on the web3 library.
Conclusion
Interacting with implemented contracts is an essential aspect to build decentralized applications. Solidity,
