OKX is part of OKG, a group that brings the value of Blockchain to users around the world, through our leading products OKX, OKX Wallet, OKLink and more. About the Opportunity OKX is going all-in on AI-native localisation. The field has long been stuck on one trade-off: you can have translation quality, or you can have scale, but not both. And the real question was never "is this translation accurate?" — it's "can the user actually understand it and get through the flow?" Web3 is the hardest place to solve this. The vocabulary reinvents itself constantly, with new tech jargon, protocol names and memes appearing every week. It sits next to dense, high-stakes trading terminology, where a single mistranslated word can mislead a user or move money. And every market has its own fast-moving regulations, so the "right" translation is a moving target that must stay compliant across jurisdictions in real time. If you want a localisation problem that is genuinely unsolved — high ambiguity, high stakes, high velocity — this is it. We're going to break the trade-off with agents. You will own the 0-1 build and launch of two things: A frontier agentic translation system that localises every market (20+ languages) with a human-in-the-loop mechanism. A self-improving agentic QA p
