Incidents
- 2025-09-25: XPL perp price spike triggers liquidations; users refunded. XPL perps on Aster spiked to about $4 while spot traded between $0.74 and $1.54, liquidating traders. Observers blamed a hardcoded $1 index price and capped mark price, which Aster did not confirm. Aster said all affected users were reimbursed in USDT. source
- 2025-10-05: DefiLlama delists Aster perp volume over wash-trading concerns. DefiLlama removed Aster's perpetual volume data after its founder found Aster's volume closely tracking Binance perps, saying it could not rule out wash trading without order-level data. ASTER fell about 10% the following day. source
Real downsides
- The Terms bar residents of the US, Canada and the UK, among others.
- VIP discounts need large ASTER holdings as well as volume, up to 2.5M ASTER for VIP 6.
- DefiLlama delisted Aster's perp volume in October 2025 over wash-trading concerns.
- A September 2025 XPL price glitch liquidated traders before Aster refunded them.

How to use Aster without getting scammed
- Only open www.asterdex.com — fake lookalike sites and "support" DMs are the most common way people lose funds on any trading venue.
- Never share a seed phrase or private key. No real support agent will ask for one.
- A referral code only changes your fee and who gets a share of it. It never needs your keys.
- Treat every new memecoin as able to go to zero. A legit venue does not make the coins on it safe.
