I can give you an article on how to call a feature from VyperConcontract Titanoboa.

Ethereum Smart Agreement Development with Vyper and Titanoboa

In this article, we will study another process of calling the contract using the Vyper programming language and the Titanoboa Framework for the Ethereum for the development.

Prerequisites

Before you start, make sure you have:

• Knowledge Vyper’s Programming Language

• Titanoboa frame mounted on your local machine or in a remote container

• Vyper smart contract for test (eg ERC20) and a separate contract that has features you want to call from that one

calling features from another contract

To call a function from another contract you will have:

• Import the necessary libraries : Import the class “VyperContract” from Titanoboa in the main contract.

• Create a target contract : Instant the object VyperConContract, which depicts the contract that has the features you want to call.

3
Call the target contract function : Use the VyperConContract method “Call () to perform the desired function.

Here is an example of a code fragment:

`Vbc

// main_contract.py (main contract)

from snekmate.Auth imports as ow

Import Titanoboa

Initializes: ow

from snekmate.Tokens Import ERC20

Initialized: ERC20 [Double: = Ow]

@Dlouth

@

Def __init __ ():

Create a target contract case

Target_contract = Titanoboa.vyperContract (“ERC20”)

Dial the function on the functions of the target contract

Target_Contract.call (Function_NAME = “My_Function”)

`

Definition of Function

For the sake of simplicity, let’s say “My_Function” in the target agreement is defined as follows:

`Vbc

// ERC20.py (Target Agreement)

Enum Functionname {

my_function

}

Struct mycontract {

Function (My_Function: bytes) -> bytes

}

`

In this example, the ERC20 smart contract sets out enum, called” Funcionname “, which indicates that it has been declared” My_Function “. The structure of mycontract denotes the functions of the target contract.

placement and launching

To place and run your Vyper Smart contracts using Titanoboa:

• Place the main contract : Use the “Place” feature to create a major contract case.

2
Place the target contract : Use the “Place” function to create the target contract with its name (ERC20) and the features you want to call (eg” My_Function).

3
Launch contracts together : You can simultaneously manage both contracts using Titanoboa built -in features or use a separate process to perform each contract separately.

an example of use of usage

Here is an example of use:

Let's say you have two smart contracts:main_contract.pyand 'ERC20.Py. The contractmain_contract.pyhas the following code:

Vbc

NO MAIN_Connects Import MyContract

Import Target Agreement

@Dlouth

@

Def __init __ ():

My_Contract = Titanoboa.VyperContract (“MyContract”)

My_Contract.call (Function_NAME = “My_Function”)

Call the function of the target contract

`

The Agreement “ERC20.Py” defines Enum, entitled “Functhionname”, which indicates that it has been declared “My_Function”. The structure of mycontract denotes the functions of the target contract.

By calling another contract function using Titanoboa, you can write a more modular and maintained code while using the Vyper smart contract and the benefits of the Ethereum blockchain ecosystem.
