Catenaa, Wednesday, December 03, 2025-Astria Network has halted its Celestia based shared sequencer system after raising $18 million over two funding rounds and operating for a little more than a year. The team stopped the chain at block number 15,360,577 on Monday.

The shutdown follows several months of reduced activity and withdrawn features.

Astria went live in 2023 with plans to offer Layer 2 networks a decentralized method to order transactions. Many L2 platforms currently rely on a single sequencer.

That process can concentrate control and allow one operator to set transaction order and collect fees. Astria promoted a modular plug in approach to spread that role across multiple participants.

The group raised $5.5 million in 2023 led by Maven 11 and another $12.5 million in 2024 led by dba and Placeholder VC. It also introduced an EVM rollup during development.

Signs of difficulty emerged during the year.

Work on the Flame EVM ended. An early test network went offline without warning. Astria later ended its Celestia validator.

Co founder Josh Bowen said in mid November that the network would close.

The project did not publish a final report. Adoption appeared limited and one major planned integration was rolled back. The team did not answer questions posted on social media or requests for comment from reporters.

The future of the code base and remaining assets is not known.

No timeline has been shared for any possible transition or handover.
