Aster Limits PAPER Perpetual Trading Ahead of Scheduled Removal
The exchange set a 9:45 p.m. ET deadline on Oct. 19 (01:45 UTC on Oct. 20), citing recent PAPER developments and potential market risks.

Aster moved its PAPER pre-launch perpetual contract to reduce-only mode and scheduled it for removal at 9:45 p.m. ET on Oct. 19 (01:45 UTC on Oct. 20), citing recent developments involving PAPER and potential market risks.
The restriction allowed traders to reduce or close existing positions but prevented them from opening new positions or adding to current ones. Aster urged users with open positions to close them before the scheduled removal.
Aster described the change as a precautionary risk-management measure intended to maintain orderly trading.
