What is Astar zkEVM?​

Astar zkEVM is a Layer-2 scaling solution leveraging Polygon's zero-knowledge technology and Aggregation Layer (AggLayer) to facilitate off-chain execution and data availability, otherwise known as a Validium, with finality guaranteed by Ethereum. This approach synthesizes the benefits of both fully integrated (monolithic) as well modular architectures, combining the best features of each.

Astar zkEVM serves as a versatile solution for global enterprises, accelerating the adoption of blockchain technology not only in Japan, but on a global scale.

In coordination with our key partners, Astar zkEVM is well-positioned to take advantage of the extensive developer base and well-established toolset existing in the Ethereum ecosystem, and boasts the following key features:

  • Some of the lowest transaction fees in the Ethereum ecosystem - Off-chain transaction batching and data availability provides some of the lowest costs for transacting in the Ethereum ecosystem.
  • Full EVM-equivalence - Smart contracts that work on Ethereum also work on Astar zkEVM.
  • Native Account Abstraction - The Astar zkEVM provides native features designed to revolutionize the end-user experience and make it seamless.
  • Top-Tier Infrastructure Integrations - Established names and brands that developers trust power the Astar zkEVM.
  • Interoperability and Exposure - With Astar zkEVM, we are supporting interoperability between the Ethereum, Polkadot, and Polygon ecosystems, uniting communities through a common vision.
  • Established Tools and Libraries - The zkEVM is compatible with tools and libraries developers already know how to use, such as Remix, Hardhat, and Open Zeppelin.
