Overview

Astar at a glance.

Astar started as Plasm Network and became one of the first parachains to secure a Polkadot slot, positioning itself as a destination for developers building decentralized applications. Here is how it works and what it is used for, not the price.

How it works

How Astar works.

Astar runs as a Polkadot parachain, so it inherits security and finality from the Polkadot relay chain rather than maintaining a separate validator set for finality. Collators on Astar produce blocks, and ASTR holders can nominate them and participate in staking. Asynchronous backing parallelizes block production and validation to raise throughput.

dApp Staking

A model where ASTR holders stake toward registered applications. Rewards are shared between the developers of those applications and the stakers who back them, funding builders directly.

Multi virtual machine support

Astar supports both the Ethereum Virtual Machine and WebAssembly contracts, so developers can deploy Solidity or Wasm based applications on the same chain.

Polkadot parachain

Astar leases a slot on Polkadot and connects to its relay chain, inheriting shared security and the ability to message other parachains.

ASTR token

ASTR pays transaction fees, is used in dApp Staking, and is used to vote in governance. Under Tokenomics 3.0 the supply is capped at 10 billion ASTR and a share of gas fees is burned.

Ecosystem & usage

What Astar is used for.

Astar hosts DeFi protocols, NFT projects, and developer tooling, and connects to the wider Polkadot ecosystem as a parachain. Its dApp Staking program is designed to channel rewards toward the applications people use.

DefiLlama

Building decentralized applications

Developers deploy EVM or WebAssembly contracts on Astar and reach users across the Polkadot ecosystem.

dApp Staking

Holders stake ASTR toward applications they support, earning rewards while directing funding to those projects developers.

Paying fees and governance

ASTR is used to pay network transaction fees and to vote on proposals that shape the network.
