OKX has launched a $100,000 developer competition known as Dev Day, inviting builders to create projects using X Layer or OKX AI. Applications are open until September 11, 2026, and participants can join either in person or remotely. The contest focuses on real-world asset (RWA) infrastructure, tokenized stock applications, agent APIs, and AI-native products.
According to OKX, the goal is to drive developer activity around X Layer, its infrastructure for tokenized real-world assets. The prize pool totals $100,000, and the competition is open to remote developers as well.
Meanwhile, OKX founder Star Xu and Binance founder Changpeng Zhao (CZ) have reignited a decade-old public dispute. The feud resurfaced after Zhao released a memoir written during his prison term, which Xu claims contains inaccuracies about events at OKCoin (the predecessor to OKX) dating back to 2015.
Xu pointed to a video that he says shows conflicting versions of a contract from that period, accusing Zhao of repeatedly misleading the public. The disagreement centers partly on a contract dispute involving early Bitcoin investor Roger Ver. Zhao wrote that Xu had accused him of forging a contract without warning, an allegation Zhao denied in a May 2015 Reddit post.
The exchange escalated when Xu questioned Zhao’s marital status, referencing earlier reporting. Zhao responded by proposing a $1 billion wager on whether his divorce had been finalized, giving Xu 24 hours to accept. Xu declined, citing compliance obligations, and asked whether Zhao’s Binance ownership stake underwent a legal separation. Zhao rejected the question, calling the matter private.
As the public spat continues, OKX is pushing forward with its developer contest, raising questions about whether the platform can maintain focus on innovation amid personal hostilities between two of crypto’s most prominent figures.
