OKX X Layer Build-X Hackathon

OKX's Build X series is a run of hackathons on X Layer, OKX's Ethereum Layer 2, and the current round is TapeOut Accelerate: a 100,000 USDT prize pool for projects built with TapeOut on X Layer.

As of October 2026: TapeOut Accelerate is live from October 16 to December 7, 2026 (23:59 UTC). OKX calls that deadline provisional, so check the official event page before you plan your final week. Earlier Build X rounds this year, including the OKX.AI Genesis hackathon in July and AI Season (August 7-21), have ended.

What does TapeOut Accelerate pay?

100,000 USDT across 11 winners: 20,000 USDT for first place, 10,000 USDT each for five second prizes, and 6,000 USDT each for five third prizes. OKX says the pool will keep growing with contributions from TapeOut's founder, team and community. Prizes are paid in stages after eligibility checks, and amounts are before tax. Shortlisted teams pitch at an offline Demo Day.

What do you have to build?

Something that uses TapeOut circuits, contracts or onchain data on X Layer, or runs on X Layer DeWEB. OKX describes TapeOut as a protocol that provides computing logic apps can use. Apps, games, online services, developer tools and circuit designs all qualify. Your description must cover the product, target users, revenue model and why users would keep paying.

My take: "Eleven winners from one pool is good odds for a niche protocol." Far fewer builders know TapeOut than know Solana, which is exactly why a focused build has a real shot here.

The honest catch

This round is narrow. If your project does not genuinely use TapeOut, it does not qualify, and existing projects only count with substantial new work done during the event. Behind the series sits the $100M fund OKX announced for X Layer builders in October 2025; treat it as background, not a promise attached to winning.
