Astar (ASTR)

Overview

Astar is a blockchain ecosystem built around decentralized applications, or dApps. Its original network runs as a Polkadot parachain: a blockchain connected to Polkadot that can run its own applications while using Polkadot’s system for checking and finalizing blocks. Astar’s native token, ASTR, pays transaction fees and supports staking and governance. ASTR also has uses across connected networks, including Soneium. (docs.astar.network)

Astar’s main idea is to give developers more than one way to build. It supports Ethereum-style smart contracts and contracts based on WebAssembly, a format that can run code written in languages such as Rust. It also has a system that directs token rewards to eligible app builders. Together, these features make Astar both a place to launch applications and a way for its community to support their development. (docs.astar.network)

History & Team

From Plasm to Astar

Astar grew out of Plasm Network, a project begun by Sota Watanabe and his team in 2019. Stake Technologies, the company Watanabe founded, developed Plasm as infrastructure for the Polkadot ecosystem. The team adopted the Astar Network name in 2021 as its plans expanded toward a broader dApp platform. Astar’s Polkadot mainnet launched in 2022. (forum.astar.network)

The project received early outside funding. Binance Labs led a $2.4 million investment round while it was still known as Plasm. In 2022, Astar announced a $22 million round led by Polychain Capital. Watanabe has since also led Startale Group, which works with Astar on parts of its wider ecosystem. Today, the Astar Foundation and community governance both play roles in the network’s development and direction. (binance.com)

Astar’s scope has changed over time. It launched a separate Ethereum scaling network called Astar zkEVM, then retired it in 2025 as its ecosystem expanded toward Soneium. The Polkadot-based Astar Network continues to support smart contracts, staking and governance. (docs.astar.network)

Technology & How It Works

Two ways to run smart contracts

A smart contract is code stored on a blockchain that carries out actions when its conditions are met. Astar offers two environments for this code. Its Ethereum Virtual Machine, or EVM, runs contracts commonly written in Solidity. Developers can use familiar Ethereum tools, including Hardhat and Foundry. Astar also supports Wasm contracts through Polkadot’s pallet-contracts system; developers commonly write these in Rust using ink!. (docs.astar.network)

This choice matters because teams can bring different skills and tools to the same network. A developer with Ethereum experience can build in the EVM environment, while another can use the Wasm approach. Astar also provides tools for interaction between its contract environments. Having two environments gives builders options, though it adds details for them to learn when an application uses both. (docs.astar.network)

Blocks and connections

On Astar Network, collators gather transactions and produce proposed blocks. Polkadot’s validators check parachain blocks and provide finality—the point at which a block is accepted as part of the chain. Astar can also use Polkadot’s cross-chain messaging system to work with other parachains. For example, assets moved from another parachain can be used in applications on Astar. (docs.astar.network)

Connections beyond Polkadot help ASTR reach other applications. The Astar Portal supports moving the token between supported networks, while ASTR serves as an ecosystem asset on Soneium, an Ethereum layer-2 network developed by Sony Block Solutions Labs. Astar Network and Soneium are separate chains with different roles for tokens and transactions. (docs.astar.network)

Tokenomics & Utility

Supply and rewards

ASTR began with an initial supply of 7 billion tokens. At launch, allocations included users and early supporters, the Polkadot parachain auction, protocol development, early backers, the team and the foundation. New tokens have also been issued as network rewards. This approach funds participants who operate the chain, stake tokens and build eligible applications. (docs.astar.network)

Astar activated its Tokenomics 3.0 model in March 2026 through on-chain votes. It lowered the maximum yearly inflation rate from 7% to 5.5% and introduced a small decline in the number of tokens issued with each block. Under that schedule, total issuance approaches roughly 10 billion ASTR over the long term. The amount actually issued can be below the yearly maximum because part of the staker reward pool grows or shrinks with participation. (docs.astar.network)

The model divides potential new issuance among several uses. Base staker rewards receive 15.8% of the allocation and an adjustable staker pool receives 63%. Eligible dApps receive 13%, the treasury 5%, and collators 3.2%. These percentages describe shares of the token issuance pool, rather than guaranteed returns to any holder. A portion of transaction fees is also burned, permanently removing those tokens from supply. (docs.astar.network)

What ASTR does

ASTR’s everyday role on Astar Network is paying for transactions, such as sending tokens or using a contract. Holders can also vote on proposals about network settings, treasury spending and dApp staking. They may lock tokens to support eligible applications through dApp staking, which distributes rewards to stakers and qualifying app teams. On Soneium, ASTR has uses in Astar-linked consumer and DeFi products. (docs.astar.network)

Ecosystem & Use Cases

Astar supports several familiar kinds of blockchain application. Decentralized finance, or DeFi, apps can let users exchange tokens or interact with lending services. Games and digital collectibles can use smart contracts to record items and actions. Governance tools let token holders take part in decisions. These are uses made possible by the network’s contract environments; each application supplies its own features and rules. (docs.astar.network)

Backing builders

DApp staking is Astar’s distinctive support system for developers. Users choose an eligible project and lock ASTR in support of it. When an app earns a place in a reward tier, its builders receive part of the network’s token issuance; participating stakers receive rewards as well. Under Tokenomics 3.0, up to 16 dApps per era—a reward-measuring period—can receive developer rewards. The model uses an annual staking cycle and ranks eligible apps within its active tiers. (docs.astar.network)

Astar’s ecosystem also extends across chains. ASTR is used in Yoki Legacy and Yoki Arcade, consumer products on Soneium that include minting, gameplay and rewards. The project identifies DeFi uses for ASTR across Astar Network, Polkadot, Ethereum and Soneium. Its listed exchange options include Comet Swap on Astar and decentralized platforms on other connected networks. This wider reach gives builders several places to create an experience around the token. (astar.network)

Advantages & Challenges

Astar’s two contract environments are an advantage for teams with different development backgrounds. Its Polkadot connection provides access to shared validation and cross-chain messaging. DApp staking gives the community a way to direct support toward builders, while ASTR’s governance role connects token holders to decisions about the network. (docs.astar.network)

Those features also create practical challenges. Developers working across EVM, Wasm and other chains must account for different tools, accounts and ways of moving assets. DApp staking’s limited number of reward-eligible places means projects compete for community support. Astar also operates among many smart-contract networks seeking active developers and useful applications. Its product plans therefore depend on turning technical features into services people continue to use. (docs.astar.network)

Where to Buy & Wallets

ASTR is available on Binance and Kraken, among other centralized exchanges listed by Astar. The project also lists decentralized exchange options, including Comet Swap on Astar Network and platforms on Polkadot, Soneium and Ethereum. Available purchase methods and services depend on the exchange and the user’s location. (astar.network)

For self-custody on Astar Network, SubWallet and Talisman support native Polkadot-style accounts. MetaMask can be configured for Astar’s EVM environment. These account types use different address formats, so the destination network and account type matter when moving ASTR from an exchange or between wallets. The Astar Portal provides tools for managing accounts and moving tokens between supported environments. (docs.astar.network)

Regulatory & Compliance

The rules governing ASTR-related services depend on where they operate and what they do. In the European Union, the Markets in Crypto-Assets regulation, or MiCA, sets rules for crypto-asset services and their providers. In Japan, crypto-asset exchange services operate under a registration and oversight framework. In the United States, securities rules can depend on the facts of how a crypto asset is offered and sold. These frameworks shape matters such as exchange access, customer checks and disclosures; they do not give ASTR one worldwide legal classification. (esma.europa.eu)

Shariah compliance is a separate question from a government’s legal treatment of a token. Islamic finance principles address interest, excessive uncertainty and gambling, among other concerns. ASTR can be used to pay fees, vote, back dApps or interact with financial applications, so a religious assessment would examine the particular activity and its terms. A network staking reward funded by token issuance, for example, has a different structure from an interest-based lending arrangement. A definitive halal judgment about a specific use calls for a qualified Shariah assessment of that use. (ifsb.org)

Future Outlook

Astar’s stated direction is to build more products linked to ASTR use. Its plans include Astar Fi, an interface for on-chain financial activity, and Astar Guard, a monitoring product. The foundation has also described a Burndrop initiative in which holders would voluntarily commit tokens to a process that permanently burns them. A proof of concept has been completed, while broader execution depends on the initiative’s final arrangements. These plans sit alongside the already activated Tokenomics 3.0 and revised dApp staking model. (ssr1.astar.network)

The question for Astar’s next stage is how well its applications connect activity across the ecosystem with ASTR’s practical roles. Its Polkadot network remains a home for smart contracts and governance, while Soneium offers another setting for token-based products. Continued development of both sides will shape how useful that combination becomes for builders and users. (docs.astar.network)

Summary

Astar combines a Polkadot smart-contract network with a wider, multi-chain ecosystem. ASTR pays network fees, supports governance and dApp staking, and appears in applications beyond its home chain. Its dual EVM and Wasm environments give developers choices, while its reward model gives token holders a way to support builders. Astar’s place in crypto rests on that mix of developer tools, community incentives and applications people can use. (docs.astar.network)
