What frontend we can use for the ethereum
By the end of this tutorial, you'll know how to: Connect a Metamask wallet to your dApp project Read data from your smart contract using the Alchemy Web3 API Sign Ethereum transactions using Metamask For this dApp, we'll be using React as our frontend framework; however, it's important to note that we won't be spending much time breaking down its fundamentals, as we'll mostly be focusing on bringing Web3 functionality to our project.
If you've never heard of any of those terms before, we recommend that you check out this Intro to React tutorial. What are we here for? Let's get started! Clone this repository into your local environment. Don't know how to clone a repository? Check out this guide from Github. When you open this cloned hello-world-part-four repository, you'll notice that it contains two folders: starter-files and completed.
In this tutorial, we will be working in this directory, as you learn how to bring this UI to life by connecting it to your Ethereum wallet and the Hello World smart contract that you published on Etherscan in Part 3. Next, open your copy of starter-files to your favorite code editor at Alchemy, we we're big fans of VScode , and then navigate into your src folder: All of the code we'll write will live under the src folder.
We'll be editing the HelloWorld. Step 2: Check out the starter files Before we start coding, it's super important that we figure out what's already provided for us in the starter files. Get your react project running Let's start by running the React project in our browser. The beauty of React is that once we have our project running in our browser, any changes we save will be updated live in our browser.
It should consist of one field a place to update the message stored in your smart contract , a "Connect Wallet" button, and an "Update" button. What your UI should look like If you try clicking "Connect Wallet" or "Update" buttons, you'll notice that they don't work—that's because we still need to program their functionality!
Let's go back into the src folder in our editor and open the HelloWorld. It's super important that we understand everything in this file, as it is the primary React component we will be working on. At the top of this file, you'll notice we have several import statements that are necessary to get our project running, including the React library, useEffect and useState hooks, some items from the.
Check out these docs. Here's what each of the variables represents: walletAddress- a string that stores the user's wallet address status- a string that stores a helpful message that guides the user on how to interact with the dApp message- a string that stores the current message in the smart contract new message- a string that stores the new message that will be written to the smart contract After the state variables, you'll see five un-implemented functions: useEffect, addSmartContractListener, connectWalletPressed, and onUpdatePressed.
Because it has an empty array [] prop passed into it see line 4 , it will only be called on the component's first render. Here we'll load the current message stored in our smart contract, call our smart contract and wallet listeners, and update our UI to reflect whether a wallet is already connected. Near the end of this file, we have the UI of our component.
If you scan this code carefully, you'll notice where we use our various state variables in our UI: On lines , if the user's wallet is connected i. On lines , we use a conntrolled component to update our newMessage state variable when the input in the text field changes. In addition to our state variables, you'll also see that connectWalletPressed and onUpdatePressed functions are called when the buttons with IDs publishButton and walletButton are clicked respectively. Finally let's address where is this HelloWorld.
If you go to the App. Last but not least, let's check out one more file provided for you, the interact. The interact. Navigate to the util folder in your src directory, and you'll notice we've included a file called interact. Later in this tutorial, we will uncomment this object and instantiate our smart contract in this variable, which we will then export into our HelloWorld. The four unimplemented functions after our helloWorldContract object do the following: loadCurrentMessage- this function handles the logic of loading the current message stored in the smart contract.
It will make a write call to the Hello World smart contract, so the user's Metamask wallet will have to sign an Ethereum transaction to update the message. Smart contracts are the foundation of dApps. Here is where the main distinctions between Web3 programming languages and other programming languages lie. When a dApp recognizes a transaction has been sent, a smart contract may execute to access the appropriate accounts through the blockchain and transfer tokens.
For example, when a player in a blockchain-based video game acquires a tokenized NFT piece of in-game gear, a smart contract can transfer ownership of the NFT to the deserving gamer. Because smart contracts are a new and unique type of program, there are programming languages specifically designed to create them. Smart contract programming languages enable developers to write contracts that securely access valuable assets, transfer ownership, guarantee transaction settlement, and much more.
When creating a dApp, the user experience will still be built by one of these frontend languages. Web3 developers should seek to learn frontend programming languages with extensive UI libraries, APIs for connecting with their favorite backend services, and those most commonly used in software development. Specific to Web3 development, the selection of frontend languages is largely the same as software development in other industries. This list is not in a specific order.
Solidity Developed by an Ethereum team, Solidity is the most commonly used smart contract programming language in web3. The language is Turing complete, fairly high-level, and object-oriented. Solidity developers thus have access to the largest Web3 ecosystem with extensive developer support resources. Building on EVM-compatible blockchains, developers can use Solidity to create Ethereum-native dApps, deploy smart contracts for a myriad of uses such as voting, transaction management, and multi-signature wallets.
For new Web3 developers, Solidity is a great place to start because of their tried-and-true coding practices, terrific community support, and smart contract versatility. Vyper was designed to make its code as simple and readable as possible. By removing unnecessary complexity in smart contract code, Vyper allows developers to avoid confusing, bug-laden code and quickly detect security risks in their smart contracts.
Vyper Use Cases As another language for programming on all EVM compatible blockchains, Vyper is a great choice to write smart contracts in the Ethereum ecosystem. The Vyper developers note, however, that Vyper is not intended as a holistic alternative to Solidity. For the sake of security, Vyper forbids doing certain things with your code that can be achieved with Solidity.
If you plan on building on EVM-compatible blockchains and need simplicity and security, Vyper is a potential web3 programming language for your smart contracts. Go Golang Golang Go is a programming language designed by Google, and it is known for its built-in concurrency features. Using Go, developers can write fast, concurrent programs with ease. With the Go implementation, developers can program scalable dApps in Golang. Go Use Cases Go is a quick language for developers to learn and has a tremendous support community.
In contrast to building dApps in an interpreted language like Python, Go runs much faster programs. Developers looking to build Ethereum-based dApps with tremendously scalable backend processing should consider Go for its robust concurrency abilities. Huff Language An assembly-level language, Huff enables developers to manually manipulate the EVM programming stack and create highly optimized EVM-based smart contracts. Rather than hiding the structure of the EVM under easier-to-use layers of abstraction, Huff intentionally exposes the EVMs inner-workings to the developer.
When the Aztec Protocol needed to power a new on-chain Ethereum program, Weierstrudel, they realized Solidity and Vyper were unable to provide the computational power their dApp needed. To solve this problem, they created the Huff programming language. Additionally, even for developers who do not necessarily need the speed, learning Huff is a great way to build a much deeper understanding of how the EVM works.
Rust Rust is a programming language used by Solana, NEAR, and other blockchains because it enables developers to write low-level code, implement systems-level controls, manage memory, and leverage parallelism. Simultaneously, Rust is designed to remain ergonomic when developing at a high-level, allowing a natural coding experience in nearly all settings. Because of Rust's ability to influence low-level code, it is extremely performant, and has inspired the development of Move, an emerging web3 programming language used by new layer 1 blockchains like Aptos and Sui.
Rust was created in , originally designed for general programming, with a goal to empower developers through its comfortability in a wide range of applications. The unique Rust compiler guarantees developers only create safe, secure code. Reviewing your code after refactors and feature adds, the compiler keeps your program stable so you can keep coding. Solana, a chain whose concurrent smart contract execution enables extremely high transaction throughput and quick block creation.
Move Originally developed by the Diem Association for developing on Diem blockchains, Move is a web3 programming language based on Rust that is designed to write safe smart contracts. When designing the language, the Move developers noticed a confusing hole in existing smart contract languages.
Smart contracts are used to control assets on the blockchain, yet the programming languages lacked any explicit type-representations for assets and access control. Accordingly, Move was designed with these necessary smart contract features designed directly into the language. However, members of the original Diem team, and Move development team have continued to create their own projects such as Aptos and Sui. Aptos is a new layer 1 blockchain looking to better solve security and scalability issues encountered by other L1s.
Sui is a permissionless Layer 1 designed specifically for speed, security, and the support of dynamic on-chain assets—everything from financial products to gaming.

Web3 Course - #5 Connect Frontend dApp to Ethereum
GUINGAMP VS NANTES BETTINGADVICE
It's open to everyone, wherever you are in the world — all you need is the internet. Ethereum's decentralized finance DeFi system never sleeps or discriminates. With just an internet connection, you can send, receive, borrow, earn interest, and even stream funds anywhere in the world.
Explore DeFi The internet of assets Ethereum isn't just for digital money. Anything you can own can be represented, traded and put to use as non-fungible tokens NFTs. You can tokenise your art and get royalties automatically every time it's re-sold. Or use a token for something you own to take out a loan. In this recipe, we will build a web interface for our game with Drizzle instead of using bare-metal JavaScript and web3.
Yes, another tool with a delicious name: Truffle, Ganache, Drizzle, these names make me hungry. Drizzle is a collection of frontend libraries that make writing DApp frontends easier and more predictable. Drizzle is based on the popular React framework, Redux, which is a predictable state container for JavaScript applications most commonly used with ReactJS for building user interfaces. Thus, it helps you write applications that behave consistently, solving the problems related to state mutation in highly asynchronous and non deterministic environments.
The Drizzle box comes with everything you need to start using smart contracts from a React App. We just unpack its box and then we can build a DApp in a few steps. You can write a React app from scratch using Drizzle packages, but to save you time and effort, I opt for using the box template and editing its code. Getting started with the Drizzle box Let's start by setting up your first Drizzle template. First, you have to create a new empty folder for the Drizzle box, otherwise Truffle will refuse to download the Drizzle box files.
Start by creating a new dedicated folder: mkdir DrizzleTontine. Then, install the Drizzle box: truffle unbox drizzle. After a few seconds two sips of coffee , it should output the following: Once the installation is done, you'll get a full DApp demo including sample contracts. Running the demo To run the example packed within the Drizzle box, you should already have the local Ganache network running. If not, start Ganache on port Ganache-cli -p
