Vyper vs Solidity Explained – Complete Guide

In today’s article, we will discuss Vyper vs Solidity and which of the course is best for you by discussing the similarities, and differences Let’s jump right into the article.


Blockchain is a system that stores data in a way that makes it difficult to modify, hack, and cheat the system. A blockchain is basically a network of computer systems that duplicates and distributes a record of transactions across the entire network.

What is Vyper?

Vyper is a comparatively new, pythonic programming language used to compose smart contracts. Vyper targets Ethereum Virtual Machine (EVM). Vyper has a straightforward/easy-to-understand syntax; one of the leading principles of Vyper is to make it nearly impossible for developers to write or create misleading programs.

What is Solidity?

Solidity is an object-oriented, high-level language for applying smart contracts. Smart contracts are programs that control the behavior of accounts within the Ethereum state.
Solidity was designed to target the Ethereum Virtual Machine and was controlled by C++, Python, and JavaScript (EVM).
Solidity is statically typed and, among other things, supports inheritance, libraries, and complex user-defined types.
You can use Solidity to create contracts for things like voting, crowdfunding, blind auctions, and multi-signature wallets.

Which to Learn Vyper or Solidity?

So, Vyper or Solidity, what should you learn about Ethereum smart contracts? So Solidity is really the standard on Ethereum. Most developers know this programming language. Most companies need a developer with Solidity skills. And most developer tools are designed with Solidity first. Like-

  • Truffle was first designed for Solidity.
  • Open Zeppelin the framework for smart contracts is also written in Solidity.

So by choosing Solidity I would say that you make your
life easier and it’s just going to be much more compatible with

Problems in Solidity

There were some problems with Solidity. For example, the syntax sometimes is not clear also it’s not very easy to audit the smart contract to make sure that it’s safe. So that’s why some programmers decided to create an alternative smart contract language called Vyper.

Vyper code is easier as compared to Solidity. And the second thing it is also easier to audit a Vyper smart contract. So that’s very important for security. So this is for the positive

Problems in Vyper

There are also some negative aspects in Vyper for example in Vyper

the language is still a bit primitive compared to Solidity for example – you don’t have dynamic arrays, so it’s a little bit difficult to work around this also, we don’t have inline assembly so you cannot really do very low-level stuff… also you don’t have modifiers for your smart contract and there are few features that are missing in Vyper and the reason they did not present it because the creator of vyper thought that these features were a way for programmers to take some risks so they wanted to eliminate this.
But Also for Windows users, Vyper is not so easy to install on Windows. Windows is definitely a second-class citizen for Vyper. And a large part of blockchain developers are still using Windows, so not really good for these guys.

Vyper vs Solidity

Easy to Learn For Python Programmers.Easy to Learn For C++ and Javascript Programmers.
Limited amount of Learning Materials.Access to multiple developer Tools and resources.
Limited Size of string and arrays.Dynamic Size of string and arrays.
Only essential features are present.Feature-rich Ethereum programming language.

Example Code For Vyper (In Python)

# Language Used - Python. # Set the version of the Vyper compiler to use. # This is important because new versions of Vyper can introduce backwards-incompatible changes. # It is good practice to specify a version to ensure that your code continues to work as expected. version >= 0.2.0 # Define the contract. contract SimpleStore: # Declare a public variable to store data. # The type is an unsigned integer (uint) with 256 bits of precision. # The "public" keyword makes the variable accessible to external contracts and clients. public storedData: uint256 # Define a function to set the value of storedData. # The "public" keyword makes the function callable from external contracts and clients. @public def set(x: uint256): self.storedData = x # Define a function to retrieve the value of storedData. # The "public" keyword makes the function callable from external contracts and clients. # The "view" keyword indicates that the function does not modify the state of the contract. # The "returns" keyword specifies the type and name of the return value. @public @view def get() -> uint256: return self.storedData
Code language: PHP (php)

Example Code For Solidity (in Javascript)

//Language Used - Javascript. pragma solidity ^0.6.0; contract SimpleStore { uint public storedData; function set(uint x) public { storedData = x; } function get() public view returns (uint) { return storedData; } }
Code language: PHP (php)


So I would suggest you first you need to learn Solidity if you are new to Ethereum and smart contracts and only after you can start to learn Vyper for fun if you want.
