Astar Network (formerly Plasm Network) is a next-generation blockchain platform within the Polkadot ecosystem, designed to empower developers to build and deploy smart contracts and decentralized applications (DApps) across multiple networks with ease. Built on the Substrate framework—the foundational software development kit (SDK) of Polkadot—Astar enables seamless cross-chain interoperability and high scalability, making it a powerful hub for Web3 innovation.
With support for multiple programming languages like Solidity, WebAssembly (WASM), and Rust, Astar removes traditional barriers between blockchains. It allows developers to create DApps that function across Ethereum, Polkadot, Kusama, Bitcoin, Solana, Cosmos, and other EVM-compatible networks—ushering in a new era of interconnected blockchain ecosystems.
Core Features of Astar Network
Astar Network stands out due to its focus on three key pillars: interoperability, scalability, and developer accessibility.
Interoperability Through Cross-Chain Bridges
One of Astar’s defining strengths is its robust cross-chain infrastructure. By integrating both EVM and non-EVM bridges, the network enables assets and data to move freely between disparate blockchains. This means developers can leverage tools and user bases from Ethereum while benefiting from Polkadot’s advanced consensus and governance models.
Whether you're building a DeFi protocol or an NFT marketplace, Astar ensures your application isn’t siloed within one ecosystem but can interact with multiple chains simultaneously.
Scalability via Layer-2 Solutions
To address congestion and high fees common on first-layer blockchains, Astar implements advanced Layer-2 scaling solutions directly into its architecture. These include:
- Plasma: Processes transactions off-chain using Merkle trees, then anchors the final state to the main chain for security.
- Optimistic Virtual Machine (OVM): Assumes transactions are valid by default and batches them for efficient on-chain verification.
- ZK Rollups: Bundles multiple transactions and verifies them using zero-knowledge proofs (SNARKs), offering strong privacy and throughput.

These Layer-2 innovations dramatically increase transaction speed and reduce costs, making Astar ideal for high-frequency applications such as gaming, decentralized exchanges (DEXs), and real-time financial services.
Winning the Polkadot Parachain Auction
Astar Network solidified its position in the Polkadot ecosystem by winning a coveted parachain slot in December 2021. Backed by over 22 million DOT in community contributions through crowdloans, Astar secured the third spot on Polkadot—demonstrating strong community support and confidence in its vision.
Participants who contributed DOT received 102 ASTR tokens per DOT, incentivizing long-term engagement. This achievement also granted Astar continuous connectivity to Polkadot’s relay chain, ensuring shared security and seamless cross-chain communication.
Before this, Astar tested its technology on Kusama via Shiden Network, its “canary” network—a live testing ground where upgrades are validated before deployment on Polkadot.
Developer Tools Powering Innovation
Astar provides cutting-edge tools that simplify cross-chain development and enhance functionality.
Ink! Programming Language
Ink! is a Rust-based language tailored for writing smart contracts on Substrate-based chains. It compiles directly into WebAssembly (WASM), positioning Astar at the forefront of the WASM movement—an emerging standard favored by Web3 pioneers for its performance and flexibility.
Developers familiar with Rust can easily transition to building scalable, cross-chain DApps without learning entirely new syntaxes.
ECDSA Signature Support
Unlike most Polkadot parachains that use the Schnorr signature scheme, Astar implements ECDSA (Elliptic Curve Digital Signature Algorithm)—the same cryptographic standard used by Bitcoin and Ethereum. This compatibility streamlines integration with existing wallets, tools, and infrastructure from these dominant ecosystems.
Native Layer-2 Implementation on Polkadot
Astar is currently the leading project bringing Layer-2 capabilities to Polkadot. While Plasma is already operational, ZK Rollups and OVM are under active development. This positions Astar as a scalability pioneer within the Polkadot network, addressing one of the ecosystem’s most pressing needs.
The Growing Astar Ecosystem
Astar hosts a vibrant ecosystem of DeFi, NFT, and infrastructure projects. With a Total Value Locked (TVL) exceeding $600 million, it ranks among the top Polkadot parachains in terms of adoption and utility.
Notable projects include:
- cBridge: A major cross-chain bridge enabling asset transfers across multiple blockchains.
- Starlay Finance: A leveraged AMM and lending protocol offering yield farming opportunities.
- ArthSwap: An automated market maker (AMM) with integrated launchpad features.
The ecosystem continues to expand through strategic partnerships and grants aimed at fostering innovation.
DApp Staking: Rewarding Innovation
A unique feature of Astar is its DApp Staking mechanism. Instead of staking rewards going solely to validators, they are shared with DApp developers whose applications users stake on.
This creates a powerful incentive for developers to build high-quality, engaging applications on Astar, aligning economic interests across the entire ecosystem.

The ASTR Token: Utility and Distribution
The native cryptocurrency of Astar Network is ASTR, which serves four primary functions:
- Transaction Fees: Required for executing transactions and interacting with smart contracts.
- Governance: Enables participation in decentralized decision-making through a future DAO.
- Staking: Users can stake ASTR to help secure the network and earn rewards (currently around 12% APR).
- Layer-2 Deployment: Developers must deposit ASTR to deploy Layer-2 solutions on the network.
With a circulating supply of approximately 2.6 billion tokens, ASTR has a market capitalization of over $500 million, placing it among the top-tier projects in the Polkadot ecosystem.
Tokenomics Overview
ASTR was distributed through:
- Parachain auction contributions (majority allocation)
- Lockdrop campaign (staking ETH to receive ASTR)
- Team, advisors, and ecosystem development reserves
- DAO treasury for decentralized governance
This balanced distribution supports long-term decentralization and sustainability.
Roadmap and Future Development
Astar follows a disciplined, milestone-driven roadmap focused on delivering core functionalities without delays. Key upcoming developments include:
- Full rollout of ZK Rollups and Optimistic Rollups
- Enhanced cross-chain messaging protocols
- Expansion of multi-language smart contract support
- Deeper integrations with major Web3 wallets and developer platforms
All upgrades are first tested on Shiden Network (Kusama) before being deployed on Astar, ensuring reliability and security.
