On December 9, 2025, a post on X claiming BlackRock had filed an S-1 for a staked ASTER ETF sparked speculation and short-lived price volatility before key figures debunked the rumor as fake.

Developers criticized parts of the community for spreading false ETF headlines, warning that such behavior undermines the project’s long-term growth.
