Aftermath Introduces Atomic Market and TWAP Orders on Its Sui Perpetuals Exchange

Aftermath Finance has introduced Atomic market and TWAP orders on Aftermath Perpetuals, its on-chain perpetual futures exchange on Sui. Aftermath said traders can bundle orders across multiple markets into one transaction: every leg fills together, or none of them do, leaving no half-built positions.

The new order type appears in the live Aftermath Perpetuals app as Atomic, described there as a way to "trade several markets at once." In the official demo, it sits in the Pro order-type menu alongside Stop Market, Stop Limit, Scale and TWAP. The same demo ends on a card reading "Atomic Orders" and "Live on Aftermath Perps." The trading interface is at aftermath.finance/perpetuals.

How Atomic orders work

In the app, a trader builds a basket of longs and shorts, sets size, leverage and max slippage, then places the basket in a single transaction. The interface tells traders that the orders "fill together in one transaction," and that if any order cannot fill within the chosen max slippage, none of them are placed.

Atomic TWAP applies the same all-or-nothing rule over time. Aftermath said a multi-market basket is split into slices that execute together at every interval. The app says each slice fills on every market or none, a slice that cannot fill retries, and if it keeps failing the whole basket is canceled. In the official demo, a "TWAP basket" then appears under the TWAP Orders tab while those slices run.

Markets, limits and fees

Aftermath Perpetuals markets are USDC-margined. Official documentation lists 72 live markets across crypto and tokenized assets, commodities, equities and FX, and the market picker in the official demo includes Crypto and TradFi filters. The official demo's basket picker reads "0 of 20 markets in basket," and the live app uses the same count-of-maximum wording. Aftermath's public documentation does not yet describe Atomic orders or state a basket-size limit.

Aftermath has not published a separate fee schedule for Atomic or Atomic TWAP orders. Its standard perpetuals fees, listed in its documentation, are based on a trader's rolling 14-day volume.
