Why it is new

What exists today, and what this does differently

What is new

Cohort credentials exist; mentor attestation tied to a capped cohort pass was not found.

Closest things out there

AttenSys manages bootcamps with NFT certificates, MeritMint issues soulbound certificates, and Unlock Protocol offers certification NFTs, but none combine a capped cohort pass with mentor-vouched graduate credentials.

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.

How it earns for you

Mentors start free and the platform takes a small cut of each pass. Studio and Academy plans lower the cut and add alumni and lineage tools. A vouch can never be bought.

The pitch, ready

Capped cohort passes with a vouch the mentor personally signs onchain for graduates who meet her bar.

Problem: A respected practitioner's word gets people hired, but it lives in DMs and referral emails, does not scale, and anyone can claim they learned from someone.

Solution: Mentors sell a fixed number of seats as a token, a helper prepares each capstone case, and only the mentor signs a vouch attestation that any employer can check without a wallet.

Why now: Cheap attestations on Base, email wallets and small models that read commit history make a personal, checkable credential practical for non crypto mentors and students.

Market: Independent mentors and cohort course creators, bootcamps and schools, plus the employers and recruiters who want a trusted signal beyond degrees.

The ask: Pilot mentors with an existing audience, one coding school for the Academy tier, and grants from public goods rounds.

Funding is never guaranteed. Check each program's rules.

For hackathons and demo days

Your 2 minute demo

Home: meet Defne, 41, in Istanbul, week 8 of a 20 seat cohort.
Cohort: show the seat string and public roster, roll Jonas's seat to cohort 5, buy a seat from the pass page with USDC.
Review: the helper prepares Priya's case, Defne signs the vouch, open the verify page.
Review: Marco's copied capstone is flagged privately, offer a redo.
Lantern: alumni review on Thursday, unlock Studio to see the lineage and let Priya start her line.
Owner Revenue: change the Studio price and cut, preview the mentor Plans sheet.
Owner Trust: ask a line that vouches for everyone to publish a written bar.
Owner Roadmap: request the v2 employer search build.

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

Experienced practitioners can mentor a small group well, and their personal word is what gets students hired. But that word lives in DMs and referral emails, it does not scale, and anyone can claim they learned from someone.

What exists and what is new

Cohort and course credentials already exist: AttenSys manages bootcamps with NFT certificates, MeritMint issues soulbound certificates, and Unlock Protocol offers certification NFTs. Research verdict: rare, medium novelty. We did not find a product that combines a capped cohort pass with a credential the mentor personally signs for each graduate who meets a stated bar, plus a visible lineage when graduates start their own cohorts.

The data it runs on

The pass contract (seat cap, price, roster), the mentor's stated bar, private progress signals from the cohort helper (commits, reviews, attendance), and the mentor's signed vouch attestation. Student code and reviews stay on their own platforms.

1.The mission

Let the people who teach well put their name behind the people they taught, and let that name travel further than an inbox.

2.Why people can't resist it

A word you cannot buy The pass buys a seat, never the vouch. Because the mentor declines some, the vouch means something.

A fair, visible roster A hard seat cap and a public roster make the cohort feel scarce and honest. No backdoor seats.

Thursday lantern hour Alumni review the next cohort's code and can start their own line, so the network keeps growing week after week.

3.How it works for real

Wallets: Privy embedded wallets with email login for students and mentors on Base, with Solana as an option. No seed phrases.

Cohort pass: An ERC-721 pass with a fixed supply per cohort, price in USDC, a resale window that closes at a week the mentor sets, and rollover to the next cohort.

Vouch attestation: Ethereum Attestation Service (EAS) on Base: a schema with cohort, bar met, and the mentor as attester. Only the mentor's key can issue it. Revocable by the mentor with a reason.

Cohort helper agent: A small model tier (for example Claude Haiku via OpenRouter) handles reminders per time zone and scheduling; a mid tier (for example Claude Sonnet) summarizes capstone evidence from the GitHub API: commit history, tests, reviews. It prepares cases and flags; it never issues a vouch.

Verify page: A public page per graduate that shows the vouch, the bar and the mentor's lineage, readable by any employer without a wallet.

Payouts: Pass revenue splits on sale: mentor share and platform fee, paid in USDC to the mentor's wallet, with an optional offramp.

4.Cost per use and pricing

Per pass mint on Base: typically a few cents in gas. Per vouch attestation: about a cent or two. Helper costs: reminders and scheduling under a cent per student per week on a small tier, and a capstone summary of a few thousand tokens on a mid tier is roughly 2 to 5 cents. Example month: one 20 seat cohort costs the owner roughly 10 to 25 dollars in model, gas and hosting.

Mentor 5% of pass sales

Up to 2 cohorts at a time, passes, vouches, the verify page and the helper.

Studio $39 per month plus 3%

Custom domain and branding, larger cohorts, alumni lantern hour tools and lineage pages.

Academy $249 per month

For schools or companies running many mentors, with shared review queues and an API for verification.

5.Growth loop

Every vouch has a public verify link that graduates share in job applications. Employers who check it see the mentor and the next open cohort. Graduates who start their own lines bring their mentor's lineage with them.

6.Risks and guardrails

Weak vouches: If a mentor vouches for everyone, the credential loses meaning. Show each mentor's vouch rate and declined count on their page.

Privacy: Student progress, code and flags stay private. Only the vouch and the bar go onchain. A student can hide their verify page.

Unfair flags: The helper can be wrong about copied work. Flags go only to the mentor, never to the public, and the student always gets a chance to explain or redo.

Consumer protection: Selling a course pass can carry refund duties in some regions. The owner should publish a clear refund and rollover policy and follow local rules.

No job guarantee: A vouch is not a promise of employment. The app must never imply hiring outcomes.

Now
One mentor, twenty seats, and a signed word for the people who earned it.
Next
Graduates open their own small lines, and the lineage shows who taught whom.
Later
Employers search by lineage and bar, not by degree, and mentors are paid for the quality of their judgment.
World
Apprenticeship returns at internet scale: anyone, anywhere, can learn from someone great and carry their word into a career.

OWNER PLAYBOOK

Own it, then chart your voyage

Nine routes from one vessel. Tap a port to open its chart.

Why own Apprentice Line

Apprentice Line lets a mentor sell a capped cohort pass and give each graduate an onchain vouch that says 'I trained this person and stand behind them'. On a course marketplace, the platform takes a cut, owns the student list and decides who sees your cohort. Own it, and the pass sales land in your wallet, the roster is yours, and every vouch carries your name as the signer.

What’s stopping you?

“I can't code.”

You set the cohort size, price and dates, then share the link. The pass, roster and vouch credential come built. You will sign vouches with your wallet, which is a button press.

“What if no one buys a pass?”

Start with people who already ask you for help. A cohort of five paying people is a real start. Cap it small so it sells out, which makes the next one easier.

“What if I vouch for someone who disappoints?”

Only vouch for graduates who completed the work you set. Your vouch is your reputation, so keep the bar clear and written. You can choose not to vouch.

“Is it really mine?”

Yes. The pass and vouch contracts deploy from your wallet on Base or Solana, and the student list exports any time.

“Do I need to be famous?”

No. You need to be one step ahead of your students and willing to show up. Many small cohorts are run by people with under 1,000 followers.

The million-dollar ladder

Mentors sell cohort passes; you can run your own cohorts or license the platform to other mentors for a monthly fee plus a small cut of pass sales. This is a target, not a promise.
