<p>Trading in perpetual futures on the Sui blockchain has picked up, with <a href="https://x.com/AftermathFi" rel="noopener noreferrer nofollow">@AftermathFi</a> emerging as the main driver of activity across the <a href="https://x.com/SuiNetwork" rel="noopener noreferrer nofollow">@SuiNetwork</a> ecosystem. Data tracked by DefiLlama points to a notable rise in perps volume for <a href="https://x.com/search?q=%24SUI&amp;src=cashtag_click" rel="noopener noreferrer nofollow">$SUI</a>, with the protocol ranking ahead of its closest rival, <a href="https://x.com/bluefinapp" rel="noopener noreferrer nofollow">@bluefinapp</a>.</p>
<h2 id="sui-perps-volume-rises-over-30-in-a-week">Sui Perps Volume Rises Over 30% in a Week</h2>
<p>DefiLlama's Sui chain overview <a href="https://defillama.com/chain/Sui" rel="noopener noreferrer nofollow">lists a weekly perps volume change of about 31.76%</a>, in line with a rise of more than 30% over the past seven days. Aftermath has recorded close to $70 million in perps volume over the period, according to the figures in circulation. Bluefin is the only other protocol close, at around $5 million in trading volume.</p>
<p>Figures on DefiLlama's perps dashboards update continuously and differ by time window and by how each page defines volume, so readers comparing numbers should check the timeframe shown. Third-party tracker PerpFinder, which draws on DefiLlama and exchange data, <a href="https://perpfinder.com/chains/sui" rel="noopener noreferrer nofollow">tracks nine perpetual futures venues on Sui</a>, and lists Aftermath Perps among the top protocols by recent volume.</p>
<h2 id="how-aftermath-perpetuals-works">How Aftermath Perpetuals Works</h2>
<p>Aftermath's documentation describes the product as <a href="https://docs.aftermath.finance/perpetuals/aftermath-perpetuals" rel="noopener noreferrer nofollow">a fully onchain perpetual futures exchange on Sui</a>, where every order, cancellation, trade and liquidation executes onchain. It runs a central limit order book in Move smart contracts rather than relying on off-chain sequencers.</p>
<p>That design differs from Bluefin, which <a href="https://perpfinder.com/chains/sui" rel="noopener noreferrer nofollow">runs an off-chain order book with on-chain settlement</a>. Security firm Certora, which audited the protocol, <a href="https://www.certora.com/blog/sui-order-book-liveness-vulnerability" rel="noopener noreferrer nofollow">described a liveness vulnerability in the order book</a> that Aftermath mitigated before the findings were published in September 2026.</p>
<p>The protocol has also faced setbacks. <a href="https://www.cryptotimes.io/2026/04/29/aftermath-finance-perps-on-sui-exploited-for-1-14m/" rel="noopener noreferrer nofollow">Aftermath's perps market was exploited for about $1.14 million in April 2026</a> after a fee misconfiguration, before the team paused the protocol. Mysten Labs and the Sui Foundation later pledged to cover user losses, according to reports.</p>
<p>The latest volume data suggests trading activity has returned to the platform, though perps volumes on Sui remain small compared with the largest decentralized derivatives venues on other chains.</p>
