Astar Network Family

Prior to commencing development, 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 Substrate and EVM RPCs.

Astar networks

Local Networks

Local 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 Environment 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.


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.



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.


Rococo is a test Relay Chain used by the Polkadot & Kusama communities. Astar team has deployed a parachain to it called Rocstar, which is mainly used for cross-chain integrations with other teams in the ecosystem. To obtain test tokens for Rocstar, please contact Astar team on Discord.

The Rocstar native token symbol is ROC.


Astar has two mainnets, like most parachains in the Polkadot ecosystem. One on Kusama Relay Chain, and the other on Polkadot Relay chain.


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.


By now you may have already guessed that Astar network is a parachain on Polkadot Relay chain.

The Astar native token symbol is ASTR.

Questions and Assignments:

  1. Using the account you created in previous chapters, visit to Astar portal, connect to Shibuya testnet and claim some tokens from the faucet. You will need them later to deploy contracts on Shibuya.
  2. Are you able to deduce how to transfer SDN tokens to Astar, and swap them for ASTR tokens?
  3. Is there a market for buying and selling SBY tokens?
