According to PANews, Astar Network has announced on its official X account that it is undergoing an upgrade, leveraging the Polkadot SDK. The network will transition seamlessly to Agile Coretime at the end of its current lease and will purchase block space as needed. This change aims to make it faster, more convenient, and more affordable for projects to join Polkadot and connect to Astar. Additionally, Astar Network mentioned that 350 million ASTR tokens, accounting for 5% of the initial supply, have been destroyed as they are no longer needed for slot auctions with the advent of Agile Coretime.
