Astar Network Launches Fixed Supply Model to Drive Institutional Growth with Soneium 

Astar Network has officially transitioned to a capped supply tokenomics model by setting a maximum of 10.5 billion $ASTR tokens. This change will remove inflationary emissions via a decay model and place the protocol in line with institutional preferences for predictable and value-compelling digital assets. Additionally, 50% of all ongoing transaction fees will be burned indefinitely to maintain ongoing deflationary pressure over the token supply.

The initiative aims to increase long-term token value and stability. The Astar Finance Committee (AFC) will use 20% of the network fees and reserve $ASTR to buy DOT, set up ASTR-DOT liquidity, and self-secure Polkadot core time slots, independent of the council. The AFC will publish monthly performance reports and maintain a public dashboard to maintain transparency in POL operations.

Integration with Sony’s Soneium to Boost Liquidity and Interoperability

Astar also expands its role to become one of Sony’s ‘Layer 2’ blockchains, Soneium, at the same time as Astar unleashes the fixed supply model. Through the Astar Portal, Astar will act as the central liquidity engine for cross-chain interoperability between the Ethereum and Polkadot ecosystems. This integration will improve ASTR’s utility and help bring more people into mining and utilizing decentralized finance platforms.

Additionally, the collaboration positions Astar as a foundational layer in Soneium’s ecosystem, facilitating seamless token bridging and liquidity flow. Revenue from Soneium’s sequencer operations will be reinvested to aid the development of Astar ecosystems. At the same time, Astar has launched as one of the first-day partners of Circle, Optimism, and Chainlink as it grows its footprint in Ethereum’s Layer 2 landscape while leading in the Polkadot network.

Roadmap and Institutional Strategy

The community discussions for implementing the fixed supply model will start in May 2025. Following research and development, full deployment is expected in the second quarter of 2026. The changes align with Astar’s broader mission of supporting scalable and secure blockchain adoption across the enterprise, entertainment, and consumer platforms.
