How to Create and Deploy Sui Smart Contracts

How to Create and Deploy Sui Smart Contracts?


Blockchain Sui looks very promising and is gaining popularity. Sui aims to provide customers Ethereum-style experiences with better scaling tools and designs. In addition, Sui provides customers with efficient, fast, and economical minting of mutable and composable NFTs. It would not have been possible with older blockchain technology. 

Sui uses horizontal scalability to maintain low gas fees. Sui’s Tier 1 decentralized blockchain platform is designed to provide the high throughput, instantaneous settlement facilitation, low latency, and low cost required to run applications for billions of users. Sui blockchain security, architecture, and features attract public attention. 

What is Sui Blockchain?

Sui is the first decentralized blockchain platform for a dynamic asset economy with low latency, high throughput, and an asset-centric programming model based on Move. Sui blockchains use the well-known Rust Moving programming language.

Sui is a horizontally scalable blockchain with no theoretical limits, using very low computing resources per transaction.

The permission-free, PoS-enabled Layer 1 blockchain was created in an attempt by developers to provide high throughput and instant settlement and empower next-generation delay-sensitive decentralized applications.

It is the first permissionless layer one blockchain designed from the ground up to enable developers and creators to create experiences that serve the next billion users on web3.

Sui uses horizontal scalability to maintain high transaction processing capacities beyond legacy payment systems.

Sui is the brainchild of Mysten Labs, a research and development company founded by the architects of the Diem blockchain and the Move language. The developer has already raised $300 million in funding and is well-positioned to grow further.

What is Sui’s architecture?

Blockchain Sui consists of three components:

  • Objects. Sui has programmable objects managed and created by Move-enabled smart contracts. These are also divided into immutable packages and special mutable data values.
  • Transactions describe ongoing changes and updates made to the Sui blockchain ledger.
  • Validators. The Sui network is processed by independent validators, each running their instance of the Sui software on a separate machine.

What language is Sui based on?

It is written in the Move programming language based on Rust. The Move bytecode language used to implement smart contracts and user transactions supports the Sui programming model.

Move is platform agnostic, allowing developers to form communities across different blockchain platforms.

This programming language is based on the idea of ​​providing more protection and security, as well as facilitating the transition from Web2 to Web3. Furthermore, the Move type system and data model support the parallel Sui convention, which guarantees the high scalability of the blockchain.

The features of the Sui blockchain

Sui has a set of unique technical features, the most significant of which are:

  • A simplified developer experience.
  • Parallel transaction execution.
  • A unique approach to security.
  • Improved UX for Web3 solutions.

Sui use cases include creator-owned decentralized social networks, and developing blockchain gaming interactions with the blockchain, such as creating equipment, leveling up a character, and so on. 

  • Simplified development experience

The Move programming language simplifies the work of developers. This way, programmers can make fewer mistakes with the underlying concepts and write less boilerplate.

Sui allows you to effectively implement composable objects or dynamic NFTs that can be grouped or updated. It provides better feedback and contributes to a more complex game economy.

  • Parallel execution of transactions 

Sui can bypass the consensus and parallelize the execution of multiple unrelated transactions using Byzantine Consistent Broadcast. It ultimately leads to increased throughput and reduced latency.

Compared to traditional blockchains, where transactions are grouped into blocks, the Sui blockchain validates them individually. Furthermore, after the execution of each transaction, a special certificate of completion is issued, which guarantees that the transaction will not be revoked.

  • Unique security approach

Sui is not focused on strict assumptions about network synchrony. the platform can maintain its security qualities under the most adverse network conditions and circumstances, such as DoS attacks or network splits.

  • Advanced Web3 solutions and improved user interface

Sui developers believe this will allow engineers to create first-class UX in the Web3 realm by providing them with quality tools from the Sui Development Kit.

Can I create my smart contract?

Anyone can write a smart contract and deploy it on the network. You should learn how to program smart contract language and have enough ETH to deploy your contract. You have to pay in gas the same way that you have to pay in gas for a simple transfer of ETH.


Facebook first developed the Move to support the Diem blockchain. It is an open-source language for writing secure smart contracts.  Move creates, defines, and manages programmable Sui objects.

Move code organization

A package is the basic unit of organization for Move code. It consists of various modules defined in .move files. The package includes the Move.toml manifest file.

The minimal source directory structure for such a package contains a manifest file and a sources subdirectory.

Move source code

The Sui platform contains the Framework Move code needed to load Sui operations. In addition, it supports several user-defined coin types. The Sui framework code includes the Coin module located in the coin.move file. The manifest file can be seen in the Move.toml file.

The package name is unique, but different packages may contain modules with the same name.

A package in Sui is also a Sui object and must have a unique name and a unique numeric identifier.

Move structs 

The Coin module defines the struct type Coin, representing user-defined coin types as Sui objects.

The Move structure type contains a set of typed fields and a name.

The Move struct type must be able to store an object in the Sui global storage. When a Coin structure is instantiated, an arbitrary concrete Move type can be passed to it to distinguish different types of coins from each other.

Move functions

The basic calculation unit in Move is a function. One of the simplest functions defined in the Coin module is the value function.

Different Functions can call this public function in other modules to return an unsigned integer value stored in an instance of the Coin structure.

The function’s body extracts the value field from the instance parameter of the Coin structure and returns it. The Move type system provides invariant struct instance arguments, passed as read-only references, that cannot be changed in the function body.

The Sui variant of the Move language defines input functions that can be called from Sui.

Login Functions 

Therefore, one of the simplest input functions for implementing the transfer of a gas object is defined in the SUI module.

The login function must have a login modifier and have no return value and only three parameters:

  • recipient – address of the intended recipient
  • c – gas facility, the ownership of which is subject to transfer
  • ctx – mutable reference to an instance of the TxContext structure

Note that this mutable TxContext reference is not required for login functions.


Existing technology suffers from restrictive storage practices and inherently unsafe programmability models. Therefore, a compromise is needed in terms of user experience and functionality.

Sui hasn’t shown her true strength yet, as she’s at the beginning of her journey. The company will have to withstand competition from popular blockchains such as Bitcoin. However, the advantages of this blockchain are obvious now.

Sui is a horizontally scalable, high-performance blockchain without theoretical limitations utilizing extremely low computation resources per transaction.
