Sponsor Hashclue

Hashclue is a live cryptographic treasure hunt running on Ethereum mainnet. A physical cache is hidden somewhere in the world. Its location is encoded in a series of clues, each locked behind an ETH payment. Players decode the clues, narrow the search area, and race to be the first to find it. The winner submits a string whose SHA-256 hash matches the value published on-chain. If it matches, the contract pays out automatically.

Each round runs until someone wins or the round is voided by dormancy. The prize pool is real money, funded by player entry and clue unlock fees, with 90% flowing directly into the pot. Players have real skin in the game. So does everyone watching.

The Audience

Hashclue attracts a self-selecting crowd of people who solve hard problems for sport. Puzzle enthusiasts, OSINT practitioners, on-chain natives, cryptographers, and competitive investigators. They are not browsing passively. They are here because they chose to be, because the problem is interesting, and because the stakes are real.

This is not a general audience. It is a concentrated one. Players read every word on the platform. They follow announcements. They discuss rounds in detail. A brand that earns credibility here earns it with people who are notoriously hard to impress.

Why Sponsor

Sponsorship places your organisation directly inside a live, high-stakes event that this audience has already chosen to engage with. You are not interrupting. You are part of the game.

Sponsorship can include named placement on the Hashclue platform for the duration of a round, recognition in round launch announcements and community communications, association with specific challenges or prize milestones, and presence at the moment of resolution when attention peaks.

We do not sell banner slots or impression packages. Every sponsorship arrangement is discussed directly and structured to fit the round it supports. If you want your brand attached to something genuinely interesting, this is it.

Sponsorship Opportunities

Round Sponsor

Attach your name to a specific round from launch through resolution. Your brand appears on the platform throughout the hunt, during the period of maximum engagement, when players are active and watching closely. Round sponsorship is the highest-visibility option and is negotiated per round.

Platform Sponsor

Sponsor the ongoing development and operation of Hashclue. Platform sponsors are recognised across the site on an ongoing basis, independent of any single round. This is the right fit for organisations that want sustained presence rather than event-based visibility.

Prize Sponsor

Contribute directly to a round's prize pool or fund a standalone community event. Prize sponsorship is the most direct form of participation. Your contribution becomes part of the stakes, and players know it. Nothing focuses attention like money on the table.
