Understanding Astar Network

Astar Network is a multi-layer Web3 platform that bridges blockchains. Astar network is a Layer 1 blockchain secured by Polkadot's Nominated Proof-of-Stake consensus mechanism and a Layer 2 zkEVM solution built with Polygon CDK technology. Astar’s dual-layer structure enables developers to build applications using multiple virtual machines, including the Ethereum Virtual Machine and WebAssembly.

Astar Network connects with Soneium, a Layer 2 solution developed by Sony Block Solutions Labs. The partnership brings blockchain technology to mainstream applications, particularly in entertainment, payments, and decentralized finance. Through integration with Chainlink's Cross-Chain Interoperability Protocol, Astar enables users to move tokens across major networks like Polkadot and Optimism with enhanced security.

What You Can Do on Astar

Developers working on Astar can write smart contracts in programming languages like Solidity and Rust. Astar supports decentralized applications across gaming, DeFi, and consumer-facing services. Astar's unique dApp staking feature enables developers to earn rewards directly from the network when people stake tokens on their applications. Staking rewards create a sustainable funding model where builders get compensated for creating valuable applications.

You can participate in network governance, stake your tokens to support favorite projects, and execute cross-chain transactions using Astar. You can access familiar DeFi protocols thanks to the network's compatibility with Ethereum, and benefit from Polkadot's security infrastructure.

ASTR Token Utility and Economics

The ASTR token powers the Astar ecosystem. When using the Astar network, you need ASTR to pay transaction fees, participate in governance decisions, and stake tokens to earn rewards. The token also enables cross-chain transfers and is the unifying asset across both Astar Network and Soneium.

Astar launched with an initial supply of 7 billion ASTR tokens. The network originally operated with inflationary tokenomics estimated at approximately 665 million tokens yearly. In April 2025, Astar introduced adaptive tokenomics that link token rewards directly to actual network activity. The tokenomic model change helps moderate inflationary pressure and makes the supply more responsive to real usage patterns. The new model attracted long-term investors seeking stability.

The network also introduced CrosschainMint and CrosschainBurn tools that enable authorized bridges to manage token supply efficiently.

How to Transact Safely Using Trust Wallet

Your recovery phrase is the most important security element of your wallet. The 12 or 24-word phrase is the only way to restore access to your funds if you lose your device. Write it on paper immediately after creating your wallet and store it in a secure physical location like a fireproof safe. Never take screenshots, save it in cloud storage, or share it with anyone. Trust Wallet will never ask for your recovery phrase through any channel.​

Only download Trust Wallet from official sources. Check that the developer name shows "Trust Wallet" before installing. Scammers create fake apps designed to steal your recovery phrase and your cryptocurrency.

Never buy cryptocurrency while connected to public Wi-Fi networks. Hackers can intercept data transmitted over unsecured networks. Use your mobile data connection or a secure, password-protected home network instead.​

Set up biometric authentication or a strong passcode to lock your Trust Wallet app and prevent unauthorized access. Keep your device's operating system and Trust Wallet app updated with the latest versions to patch security vulnerabilities. Enable Trust Wallet's Security Scanner feature, which warns you about potential risks before you complete transfers.

Your Next Steps

Purchasing ASTR through Trust Wallet puts you at the center of the Astar network, connecting Polkadot's security with Ethereum's vast developer ecosystem. Astar's focus on interoperability puts your tokens to work across multiple blockchain environments, from DeFi applications to gaming ecosystems and the Soneium network.

The network's dApp staking system lets you earn rewards by delegating tokens to innovative projects. Prioritize security by protecting your recovery phrase, verifying app authenticity, and avoiding public networks when making transactions. Begin with a small investment as you explore the platform's features, keeping in mind that your security foundation enables safe participation in Astar's expanding Web3 infrastructure.​
