Ethos announced its first-ever Vibeathon, a vibe-coding contest happening next week with $40k+ in prizes and 10M XP. Open to anyone using Ethos’ onchain reputation, with Claude credits, Base sponsorship, and live judging on X.

Ethos, an onchain reputation and identity protocol, has announced its first Ethos Vibeathon, a 72‑hour “vibe‑coding” contest focused on building products powered by Ethos’ onchain reputation primitives. The event is scheduled for January 19–22, 2026, offers over $40,000 in prizes plus 10 million XP, and is open to anyone who builds applications that integrate Ethos reputation onchain. According to the official Vibeathon page and Ethos’ announcement on X, participants will compete to create “reputation‑powered products” using Ethos’ SDKs and onchain reputation graphs, with categories that emphasize novel uses of identity, trust scores, and social data on Ethereum and Base. All participants receive Claude Pro credits to support AI‑assisted building, and the event is sponsored by Base, underscoring the alignment with the broader Base ecosystem and its push for consumer‑facing onchain apps. Projects can be built by solo developers or teams, and selected finalists will present in live judging on X, where judges will review the product experience, technical integration of Ethos reputation, and potential real‑world use cases. Vibeathon situates Ethos within the growing “vibe coding” and AI‑assisted hackathon trend, where builders use natural‑language workflows and AI tools to quickly prototype software, but adds a crypto‑native layer by requiring onchain reputation integration as the core constraint. For the Web3 ecosystem, the contest functions both as a developer acquisition initiative for Ethos and Base and as a testbed for practical uses of onchain identity—such as reputation‑gated access, soulbound credentials, and trust‑aware social apps. The prize pool, XP rewards, and AI credits indicate that Ethos is incentivizing not just one‑off hacks but longer‑term engagement with its reputation graph, aiming to seed an ecosystem of applications where user history and onchain behavior can be used as a programmable primitive.
