Ethereum Layer-2 Platform, ZKSync, Releases New SDK in Swift

ZKSync, an Ethereum layer-2 platform designed to scale transaction throughput using zero-knowledge (ZK) proofs and Rollups, has released a new software development kit (SDK) in Swift.

ZKSync Releases SDK in Swift

In a tweet on January 17, ZKSync said the goal is to make their features more accessible to developers and dApps. With a Swift SDK, ZKSync would support more platforms and use cases, especially for teams building iOS and macOS applications on ZKSync 2.0.

Swift is the programming language behind iOS and Mac devices. However, Swift cloud storage software for iOS and macOS enables users to retrieve data through an API. Cloud storage is scalable and designed to store unstructured data that can limitlessly grow. 

SDKs in Popular Programming Languages

Besides Swift, ZKSync also supports Python, Java, Android, Rust, and Dart programming languages. Dart, the layer-2 platform explains, is the “unofficial” open-sourced SDK in Alpha. However, the layer-2 portal plans to support more SDKs in various programming languages to cater to their expanding developer community, allowing them to build more solutions addressing multiple problems.

SDKs are critical for developers since they allow the building to be simpler, faster, and standardized. For creators to integrate into existing services, they require kits, which often include necessary documentation, code samples, libraries, APIs, and more, providing guidance when developing blockchain solutions. However, within any developer kit, APIs are critical because they act as an interface for dApps to relay information and coordinate. 

Scaling Ethereum Using ZKSync v2

ZKSync layer-2 is building a solution for users to quickly transfer ethereum (ETH) and ERC-20 tokens without paying the relatively high fees in the mainnet. 

Ethereum gas fees often fluctuate depending on on-chain activities. As ETH prices rally, DeFi and NFT activities often expand, leading to high gas fees. With Gas rising on a public, transparent layer, users have to pay more to transfer or execute smart contracts.

The layer-2 platform is positioning itself as a better alternative for teams and users, preferring scalability, privacy, and security. Following the launch of the ZKSync 2.0 mainnet, there is a scaling and privacy engine using ZK proofs. Earlier, Vitalik Buterin, the co-founder of Ethereum, relayed his confidence in ZK Rollups that dApps on ZKSync leverages. In the co-founder’s assessment, ZK Rollups “will win out in all use cases.”

ZKSync 2.0 Is Live on Mainnet

Users deploying on the ZKSync 2.0 mainnet, which launched in Q4 2022, enjoy low fees and faster transaction settlement. Developers are free to experiment and add more features.

For instance, ZKSync supports account abstraction for users to pay fees in other tokens apart from ETH and build smart contracts in Vyper or Solidity. The layer-2 solution also supports Atomic Swaps. It is a feature that ZKSync creators say can benefit cryptocurrency exchanges.

NewsBTC reported earlier that Optimism, a general-purpose Ethereum layer-2, and ZKSync competitor, was more Gas efficient despite revenue and assets under its management dropping.
