Astar Network

Introduction

Astar Network is a scalable and interoperable infrastructure for Web3.0. Since Astar Network is built with Parity’s Substrate framework, it can be a future Polkadot parachain that also acts as a scalable smart contract platform. The Polkadot Relaychain, by design, does not support smart contracts. This allows Astar the opportunity to fill in this gap. Scalability is obviously one of the most crucial demands dApp developers have. Ideally, the developers can build whatever applications on Astar Network without having to consider its scalability.

The Astar Shiden network is built on the Kusama parent chain.

Appendix

Shiden token

The Shiden token SDN is the native token of the Astar Shiden network. This is similar to Ether in Ethereum. To interact with the Astar Shiden network, SDN tokens are required to pay gas fees. The Covalent API response returns gas_* fields in fiat units.
