Still remember one late night on a weekend back in 2021 or 2022, Zakk was always online remotely helping me write code and fix bugs. At that time, OKX started paying attention to user experience, launched the sub-account system, and then focused on developing the wallet. They supported more and more chains, and the features closely followed the feedback from us 'on-chain pros.' From what I recall, their team really valued product research—whenever they found something that wasn’t user-friendly, they’d fix it quickly. I also remember @Haiteng_okx telling me several times that Lao Xu is the type who uses the product himself. He’d often encounter features that weren’t working well in the middle of the night and directly @ the person responsible in the work group, demanding improvements. People internally were pretty scared of being @’ed. During that period, the OKX wallet improved visibly at an incredible pace, becoming the industry leader and the best wallet out there. For those of us interacting on-chain every day, it really made a difference. It wasn’t until last year that I finally met Zakk in person after knowing him online. He’s just like he is online—low-key, reserved, and definitely a tech genius. Gradually, I noticed Zakk started interacting on X, checking out everyone’s feedback. With a team like xlayer, I’m sure they’ll keep getting better and better. That last sentence he mentioned about the meme attitude—it’s pretty thought-provoking, huh?
