What Aster listed
Aster announced on its official X account on 23 October 2026 that IOST is its latest perpetual futures listing, with leverage of up to 10×. A perpetual has no expiry date, so a position can stay open as long as the trader keeps enough margin.
Aster's public futures API confirms the market as IOSTUSDT. It is listed as a perpetual with USDT as both the quote asset and the margin asset, and its onboarding time is 16:05 UTC on 23 October 2026, about half an hour before the announcement. Profits, losses and margin on this market are counted in USDT.
Order sizes on the new market
The API sets a minimum order value of 5 USDT and a minimum size of 1 IOST, with sizes in whole tokens. The price step is 0.0000001 USDT, which reflects IOST's low unit price. Market orders are capped at 100 million IOST each. Aster can change these parameters, so the order form is the place to check current limits before trading.
What the announcement leaves out
Aster's post gives only the token and the maximum leverage. It does not mention trading fees, funding rates, a launch promotion or which countries can use the market. Leverage of up to 10× means a price move of around 10% against a fully leveraged position can wipe out its margin, so position sizing matters, and readers should check local rules before trading.
