Blockchain technology will always be a game changer for most enthusiasts. With the appearance of cryptocurrencies, one of the financial use cases of blockchain has come into the limelight. It also supports smart contracts that pave the way for more use cases and utilities for blockchain technology.
Based on high-value smart contracts, another equally important question arises, how to write them? The most common platform for this purpose is the Near network. But before explaining the process of building a smart contract step by step, it is worth understanding what the Near platform is, what programming language should be used, and whether it is possible to conduct a Near Security Audit.
How to Write Smart Contracts and Deploy Them?
Near supplies a robust and advanced user background for dApp users on the best digital market ecosystems. It is environmentally friendly and is becoming one of the best digital marketplace ecosystems. The sharding mechanism the NEAR ecosystem uses guarantees smooth data ingestion and completes it easy to scale dApps on DeFi platforms. Therefore, writing smart contracts on this platform has many advantages, but how to do it?
#1 Setting Up Testnet
The most straightforward way to build a Near account is to use its wallet. NEAR has multiple development networks that perform independently. Creating a mainnet account is nearly equal to testnet but needs initial account name funding.
When calling smart contracts, it doesn’t matter if the developing dApps are written in Rust or AssemblyScript. Instead, all core concept of the contract code is gathered to WebAssembly and deployed on the web to run on a virtual machine.
You will operate the yarn dev command for most programs, but you can easily do it with the Near CLI and Near dev-deploy for TestNet.
- Look at Near Explorer and explore all transactions and blocks created on Near. Try to find the account you just created and view the generated transactions.
- Install Near-CLI is a command line interface that permits one to interact with Near efficiently. Its documentation includes all Near-CLI commands with samples.
- Try a Near login command. It will redirect you to your Near wallet and store its account key locally.
Once the testnet has been verified, dApp users are free to run the local node as desired.
#2 Creating a Smart Contract Code
There are two flanks to the code:
- The backend code exists in the assembly folder. You can open it at Near blockchain when running yarn deploy: contract.
- The frontend code lives in the /src folder. It is a perfect place for exploring. You can learn how the front end connects to the blockchain network, especially the Near blockchain.
When you configure a connection to the network’s platform, you can configure the contract interface by indicating a wallet linkage and wiring up all needed contract methods.
#3 Deploy a Smart Contract on Near Platform
Each Near smart contract has its associated account. When you operate yarn dev, the smart contract is deployed to the NEAR live testnet via a temporary account. To make it permanent, follow these steps:
- Visit the NEAR wallet and create a new account. Then, deploy these smart contracts in that. And, finally, authorize Near CLI and follow these steps:
- Change the line setting the contract account in src/config.js.
- If you are forking a repository, change the remote URL of the repository that you have “existed” access to. It will automatically open GitHub Pages from the command line. Dedicate it and create a new repository.
- Enter the following command: yarn deploy.
Find out more about the deploying command. It develops and deploys smart contracts on the Near. And also uses gh-pages to build and deploy frontend GitHub contract code.
What Languages Are Better to Use at Near Blockchain?
You can assemble Near a smart contract in any language that sustains Web Assembly (Wasm), but it keeps the following:
- Rust (Near SDK-RS) helps improve the security of the Rust programming language for writing helpful contracts.
- AssemblyScript (Near SDK-AS) helps smart contracts look like TypeScript for their particular execution. Its associated compilation tools are not used to develop decentralized financial programs.
Let’s understand the basics of invoking Smart Contracts on Near.
What Is Near Network Protocol?
The Near protocol is a layer 1 blockchain that operates sharding technology for scalability. In addition, it operates a smart contract and a PoS consensus mechanism to guarantee the platform’s security. The project is being developed as a loud community-driven c for hosting decentralized programs (DApps).
The NEAR platform contains an expansive field of programming instruments, languages, and smart contracts with other related capabilities. In addition, the platform has a simplified registration process with friendly account names instead of crypto wallet addresses.
The NEAR platform is one of the most advanced protocols in the blockchain network, technologically progressive and ingenious in many ways. It focuses on the development of decentralized applications with the introduction of sharding technologies for scalability.
Near supplies advantages such as human-readable account terms rather than cryptographic wallet addresses, permitting users to interact with the network and any contract. In addition, its potencies complete the local network for developing and deploying a contract, dApp, and blockchain service.

It consists of an ever-expanding network of plenty of members worldwide. Furthermore, it is a secure, no-access blockchain platform using a particle validation consensus tool.
It is a method of partitioning a database for scalability in which the network infrastructure is divided into smaller pieces, called shards, to handle a small fraction of network transactions. For example, this Near method is called Nightshade.
In addition to many advantages, economic efficiency is most often singled out. For example, the network charges users lower transaction fees, which are less than the average 3G blockchain. In addition, developers contribute to the evolution of the ecosystem.
Rust is designed for high-quality contracts and comes up for all types of networks. Therefore, many developers prefer Rust as a more versatile building tool and easy way of deploying smart contracts.
