Networks

Overview​

Prior to commencing development, especially, it's important to understand the Astar Network family, and choose an appropriate network based on what you would like to do. Currently, there are a number of networks available, including the Local network which runs exclusively within your development environment. All networks support EVM RPCs, and Astar Parachain supports Substrate RPC as well.

Astar networks

Local Networks​

Substrate Node​

You can clone the Astar repository and run the local node provided, or download the precompiled binary and run it, instead. Both methods are described in the Build section.

Swanky Node​

Swanky Node is a Substrate based blockchain configured to enable the smart contract module pallet-contracts, and other features that assist local development of Wasm smart contracts. For more information about Swanky Node, check out the Swanky Suite section.

Zombienet​

With Zombienet users can download arbitrary Relay Chain and parachain binaries (or use images) to setup a configurable local test network. Users will have access to all privileged actions on the Relay Chain and parachains, which simplifies testing. For more information about Zombienet, check out the Build Environment chapter.

Testnets​

Shibuya (Substrate)​

Shibuya has nearly the same chain specifications as Shiden & Astar, and provides an ideal environment for developers to test and debug, prior to launching their dApp on mainnet. Shibuya is running as a parachain of the Tokio Relay Chain, which is managed internally by the Astar team, and supports Shibuya, only, as test parachain.

The Shibuya native token symbol is SBY.

To obtain test tokens from the faucet, please visit the Astar Portal and connect to Shibuya. If for any reason the faucet is empty, please contact the Astar team on Discord.

zKatana (Sepolia) - Deprecated​

An early iteration of the zkEVM testnet that used zk rollup architecture. Now deprecated.

zKyoto (Sepolia)​

zKyoto is a Validium-based network connected to the Ethereum Sepolia testnet and Polygon AggLayer. It is the testing and proving ground for dApps deployed on the Astar zkEVM.

Mainnets​

Astar has three mainnets. One parachain on Kusama, One parachain on Polkadot, and a zkEVM-based network on Ethereum Layer 2.

Shiden Parachain (Substrate)​

Shiden is a parachain connected to the Kusama Relay Chain, and used to deploy and test new releases of Astar runtime in a live production (canary) environment. Shiden is not considered a testnet since SDN has its own tokenomics and value, but is used to validate and stabilize new software releases and upgrades for Astar Network.

The Shiden native token symbol is SDN.

Astar Parachain (Substrate)​

By now you may have guessed that Astar parachain is connected to Polkadot Relay chain.

The Astar native token symbol is ASTR.

Astar zkEVM​

Astar zkEVM is a Layer 2 scaling solution for Ethereum, powered by Polygon AggLayer. Technically referred to as a Validium, the zkEVM combines zk rollups with modular data availability, synthesizing the best features of each.
