Sui's native features enable application developers to create powerful products and user experiences.

According to DefiLlama data, Sui's TVL exceeded $402 million on January 28, ranking among the top ten TVLs of all blockchains!

Sui's innovative native features pave the way for DeFi applications and provide users with a great experience. Each native feature, from facilitating efficient shared liquidity to simplifying user interaction, plays a crucial role in shaping Sui DeFi.

Examining the core of these native features one by one, it is evident how they significantly impact DeFi applications. When considered collectively, their unique capabilities in enhancing user participation and experience within the Sui DeFi ecosystem become more apparent.

DeepBook

DeepBook is an important part of Sui DeFi, designed as a protocol for efficient shared liquidity across multiple applications. As a Central Limit Order Book (CLOB), DeepBook systematically records buy and sell orders in chronological order and autonomously identifies matches between them to achieve smooth trade execution. Leveraging Sui's high performance, applications can utilize DeepBook to execute trades with low latency and high throughput. As a native protocol within the Sui ecosystem, DeepBook seamlessly provides access to a large amount of liquidity to DeFi applications through simple integration, effortlessly meeting the demands of market and limit orders.

DeepBook efficiently stores unfilled orders in a pool and removes them upon successful matching with corresponding orders. DeepBook enables the creation of liquidity pools for any asset pair in a permissionless manner. As the first native liquidity layer on Sui, it fully leverages Sui's robust network layer and unique data model, simplifying the process of developing DeFi applications within the Sui ecosystem.

zkLogin

zkLogin is a solution to the challenge of onboarding new users to explore blockchain applications. The lack of a simplified login process often creates barriers for first-time users of blockchain applications, leading to a significant loss of new users. In contrast, zkLogin simplifies this process by allowing users to securely create accounts and transact using their existing Web2 login credentials, as detailed here.

zkLogin provides developers with flexibility to offer an invisible wallet for user interaction with the blockchain or a simpler way for users to access their on-chain assets. It seamlessly integrates with existing account types, such as mnemonic phrases and hardware wallets, catering to both beginners and experts based on user preferences. This versatility enhances the accessibility and user-friendliness of DeFi applications within the Sui ecosystem.

As an integral part of Sui, zkLogin empowers application builders to provide the best user experience, catering to individuals who prefer using Web2 logins. zkLogin enhances accessibility and usability, fostering a more inclusive environment among users using DeFi applications within the Sui ecosystem.

Sponsored Transactions

Sui addresses challenges around blockchain gas fees by introducing sponsored transactions. Requiring new users to pay fees with the native token of the underlying blockchain can create unnecessary user friction. For users unfamiliar with blockchain applications, this may lead to immediate abandonment.

Sponsored transactions eliminate entry barriers related to gas fees, allowing applications to sponsor specific user transactions and abstract gas fees from the end-user experience. Sponsored transactions on Sui provide fine-grained control over gas fee sponsorship, offering developers unique incentives to enhance user engagement and reduce friction for first-time blockchain users. While shifting the responsibility of gas fees from users to applications may seem like an unlikely business model, it provides flexibility for builders to determine their revenue model that best suits them.

Programmable Transaction Blocks

As a native feature of Sui, Programmable Transaction Blocks (PTBs) provide unique possibilities for composability and greatly simplify interaction between end-users and the blockchain. Unlike the traditional approach of requiring multiple transactions to execute simple operations, PTBs enable bundling, signing, and submitting a series of complex transactions in a unified process. Each command is executed sequentially, allowing the result of one command to be used in subsequent commands, ensuring a coordinated and atomic process where the entire block fails if one command fails.

PTBs significantly enhance the experience for application developers and end-users, simplifying and consolidating complex transactions. This capability allows for the creation and execution of unique DeFi strategies involving multiple applications and interactions within a single transaction block. As a powerful tool, PTBs contribute to a seamless and user-friendly blockchain experience, providing a simplified approach to streamlining interactions within the DeFi ecosystem on Sui.

Kiosk

Sui's Kiosk native feature allows users to maintain full control of their assets while selling them. When selling items such as NFTs, users often need to relinquish certain ownership-related permissions. For example, an NFT owner may want to retain functional access related to ownership while selling it. Kiosk not only facilitates the transfer of digital asset ownership but also enables creators to define specific policies for asset types. This includes custom transaction functionalities such as auctions, providing a multifaceted solution for users seeking seamless interaction and trading of their assets.

Essentially, Kiosk is a simple and highly customizable tool for building and participating in business applications on the blockchain. Similar to a real-world kiosk owned by a single owner and designated for various items, Kiosk streamlines the process of trading unique assets. Whether for individuals or large markets, Kiosk provides an all-in-one solution, eliminating the need for additional layers or third-party services typically required on traditional networks and some other blockchains.

Enhancing the DeFi Experience

A closer look at Sui's native application features reveals how DeFi applications on Sui provide a powerful user experience. Applications can leverage DeepBook for instant access to deep liquidity and various trading functionalities. zkLogin and sponsored transactions eliminate significant blockchain adoption barriers such as wallets and gas fees. PTBs offer powerful composability while simplifying user interactions. Lastly, Kiosk provides a unique approach to digital asset trading with its powerful auxiliary functionalities.

Sui's development is driven by a vision to provide the best experience for end-users and developers. The focus of Sui's development lies in empowering application builders through Sui's native features, which is crucial for realizing this vision. Stay tuned for improvements and new native features coming throughout the year. It's an exciting time for builders on Sui!
