Kemi carried her five-stack through a regional bracket but has nothing to show scouts except clips anyone could edit. With Clutch Witness she logs a moment, tags the teammates who were there, and it only becomes a permanent attestation once at least two of them co-sign. Her profile becomes a timeline of plays vouched for by the people who were in the lobby.
Moment logging with clip link, teammate tag and co-sign flow, quorum rule, attestation contract, public player timeline page.
Reshape it entirely: new features, your flows, your brand end to end, integrations you need. We scope it with you.
Turns teammate trust into the proof layer for amateur gaming skill: a moment only counts when the people who saw it sign it, with a quorum rule and a public vouch graph.
Honeycomb on Solana Attestation Service issues achievement attestations and Elympics with vlayer proves Steam stats; SkillSet (ETHGlobal) did peer-approved skill certificates. None use teammate quorum co-signing of specific in-game moments.
Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.
Consumer identity app with onchain attestations on Base.
Fits if deployed on Solana with SAS attestations.
The complete Clutch Witness app: squads co-sign the plays players actually made, building a gaming record nobody can fake alone, with a paywall, owner console and witness agent built in.
Every buyer gets the same finished app. Basic branding and copy changes come through a quick form.
Your admin side: revenue, paywall editor, users, rules and the agent log.
Referral and growth mechanics, switched on when you are ready to grow.
Logging and co-signing are free. Players pay for a pro profile to share with coaches, and tournament organisers and collegiate programs pay monthly to sign brackets and scout.
No per play fee. Attestation gas on Base, Solana or Arbitrum is a few dollars a month and can be sponsored.
Prices are yours to set. Illustrative, not a promise of income.

Custom work from $800: your game's roster sources, a Discord bot, organiser branding or a collegiate deployment. Scoped on a call.
The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.
Amateur players who want a shot at college teams, orgs or scouts have only clips and stat screens, which are easy to edit or borrow. Their real proof is the people who were in the lobby with them, and that proof is never written down.
Achievement attestations already exist: Honeycomb on the Solana Attestation Service issues achievement attestations, Elympics with vlayer proves Steam stats, and SkillSet (an ETHGlobal project) did peer approved skill certificates. None found use a teammate quorum to co-sign specific in-game moments. Research verdict: rare, medium novelty; attestations are not new, the witness quorum for single plays is.

Make the word of the people who were there count, so amateur players can prove what they actually did.
Your squad is your proof A play only counts when teammates who were in the lobby sign it, so it means something to a coach.
Honesty is visible Witnesses can correct a claim, and honest refusals make their vouches worth more.
Sunday co-sign queue A short weekly list of plays your squad is waiting on, with a witness streak.

Cost per use: unlocked when your app is paid in full.
Every co-sign request pulls a teammate into the app, and every timeline shared with a coach shows four more names. Organisers join because their signed sheets make their brackets the trusted source.

Amateur players have clips anyone could edit and nothing scouts can trust. Clutch Witness lets a player log a moment, tag the teammates who were in the lobby, and only turns it into a permanent attestation once enough of them co sign. Owning it means you run the vouch graph for your scene: your brand on every player timeline, your relationships with teams and tournament organizers, and the revenue from both.
Yes. Moment logging with clip links, teammate tagging and co sign, quorum rules, the attestation contract and public player timelines are built. You pick chain, game list, quorum size and colors and deploy from your wallet with the guide.
A small group can collude. Quorum rules, a public vouch graph and reputation for vouchers make it costly. It is stronger than a clip alone, not a court verdict. Say that clearly.
Many will not, at first. Use the easiest login available and keep crypto words out of the main flow.
Some semi pro orgs and collegiate programs are open to it. Start with a local scene and one org that will look.
Yes: the attestation contract deploys from your wallet and every player timeline lives on your instance.
Teams and players pay for pro profiles; tournament organizers and collegiate programs pay monthly to verify standout plays and scout from the vouch graph.
