Incidents
- 2025-10-11: Multi-hour outage during the October 2025 liquidation cascade. Lighter went down for roughly four hours during the October 10-11 market crash. A Beosin analysis published by Odaily attributes it to sequencer and database overload, including database index corruption, and puts the LLP vault loss at about 5.35%. source
- 2026-02-26: ARC position collapse and auto-deleveraging. A trader lost about $8.2M when a large ARC long collapsed. Around $2M was liquidated on the book, the rest passed to the LLP, and auto-deleveraging closed some profitable shorts. ForkLog reports the LLP loss at about $75,000. source
Real downsides
- Free Standard accounts carry 300 ms taker latency versus 140 ms on paid Premium accounts.
- The Terms exclude US, Canadian and UK residents, among others.
- A roughly four-hour outage during the October 2025 crash left users unable to manage positions.
- Referral codes cannot be added after sign-up, and all referral rebates are discretionary.

How to use Lighter without getting scammed
- Only open app.lighter.xyz — 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.
