The next feature X is rolling out lets you place orders directly by clicking on a Cashtag—no need to jump to an exchange or switch wallets. But the implementation logic boils down to three possible approaches: 1️⃣ In the short term, it’s most likely to integrate with a third party or exchange, with matching and custody handled outside of X. Because it’s impossible to build an exchange from scratch and launch it in just a few weeks. 2️⃣ Build an aggregation layer + connect to DEX: X could create a front-end trading interface that calls DEX aggregators like 1inch or Jupiter on the backend, with wallet connections handled via self-custody. But there’s a practical issue here: Average users don’t know how to sign with wallets, the Gas experience is terrible, fiat on-ramps are complicated, and U.S. regulators are increasingly sensitive about DEX interactions. If the goal is to enable direct trading from the timeline, they’re definitely aiming for a Web2-level user experience. 3️⃣ So in the long term, it’s bound to evolve into the third approach: X building its own exchange, which is the most challenging option. If they launch a CEX: they’ll need licenses, custody solutions, risk controls, clearing systems, and KYC. This is already a Coinbase-level engineering project. Based on Musk’s style, my guess is: In the first phase, they’ll definitely integrate with a third party. In the mid-to-long term, they might acquire a trading infrastructure. The ultimate goal is to unify payments, stocks, and crypto into one financial super app. Looking at Musk’s track record, every move he makes fundamentally disrupts the industry he enters. So here’s the question: if X controls both global attention and trading access, who’s the first to have their cheese stolen? This tweet is sponsored by @bcgame.
