<div id="readability-page-1" class="page"><div><ul><li>Dollar-denominated margin, premium, and settlement across BTC and ETH options, with multi-stablecoin support and cross-product margining, built for institutional compliance standards</li></ul>DUBAI — OKX, a leading global fintech company and crypto trading platform, today announced the launch of USDSⓈ-M Options on Bitcoin and Ether, available to traders in the UAE and Australia* under OKX's regulated derivatives frameworks. Both products are live on web and the app.The launch extends OKX's institutional product build-out, following its recently announced collaboration with BlackRock and Standard Chartered on BUIDL, and brings fully dollar-denominated options to the platform for the first time. Margin, premium, Greeks, P&amp;L, and settlement are all expressed in USD, with USDC and USDG accepted as settlement currencies alongside existing coin-margined options on the same chain.For desks that operate in dollars, coin-margined options have often remained outside reach. Internal compliance frameworks, treasury policies, and reporting requirements built around USD create friction when collateral and settlement are denominated in crypto.USDSⓈ-M Options address this directly: margin is posted in USD, USDC, or USDG; premiums are quoted and paid in dollars; and settlement at expiry lands in the stablecoin of the trader's choice.&#34;Institutional traders have been clear about what they need: Bitcoin and Ether exposure that fits within a dollar-denominated compliance and reporting framework, from the moment collateral is posted through to settlement,&#34; said an OXK spokesperson. &#34;That is precisely what USDSⓈ-M Options deliver. Combined with cross-product margining across our unified pool, traders can now manage options, perpetuals, and spot within a single account without fragmenting collateral or navigating multiple venues. We built this for the desks that have been waiting for a regulated, dollar-native options product at this level of sophistication.&#34;The product integrates into OKX's unified margin pool, meaning a long BTC call offsets against a short BTC perpetual within the same account. Desks running options alongside a broader derivatives programme do not need to segment collateral or post margin twice for positions that hedge one another.ִProduct Comparison<div><table><tbody><tr><td> </td><td>Coin-margined Options</td><td>USDSⓈ-M Options - NEW</td></tr><tr><td>Margin currency</td><td>BTC or ETH</td><td>USD, USDC, or USDG</td></tr><tr><td>Premium quoted in</td><td>Crypto</td><td>USD</td></tr><tr><td>Payoff type</td><td>Inverse</td><td>Linear</td></tr><tr><td>Payoff formula</td><td>(S − K) / S × multiplier × qty, in BTC/ETH</td><td>(S − K) × multiplier × qty, in USD</td></tr><tr><td>Min. contract size</td><td>0.01</td><td>0.01</td></tr><tr><td>Example contract</td><td>BTC-USD-241231-50000-C</td><td>BTC-USD_UM-241231-50000-C</td></tr></tbody></table></div>A single toggle on the OKX options chain switches between both products.
