Who it is for

Seyi closes a loss. Post Mortem asks three questions, tags the mistake, and after a month shows him his top three repeat errors with onchain proof of improvement.

Why it is new

What exists today, and what this does differently

What is new

Onchain-anchored post-trade reviews were not found as a product, though adjacent tools exist.

Closest things out there

Offchain journals like Edgewonk and Tradervue do reviews, and BausBank vtr-core anchors decisions, but none found tying reviews to onchain fills with improvement attestations.

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.

The pitch, ready

A two minute review after every closed trade that compounds into a personal playbook, with improvement provable onchain and the journal kept private.

Problem: Most traders repeat the same few mistakes, revenge entries, moved stops, oversizing, but never review consistently. Journals feel like homework, and judging trades by profit teaches the wrong lessons.

Solution: Read only fill import, three tap questions on close, process tags decided by the fills, an encrypted journal, a weekly rule, and a monthly score attested on Base without trades, notes or PnL.

Why now: Perps volume moved onchain to venues like Hyperliquid with public fills, attestations on Base cost under a cent, and small models can compare answers with fills for a fraction of a cent.

Market: Active onchain perps traders, plus the coaches, trading communities and prop programmes who want members to review their decisions.

The ask: Ten coach groups for a pilot, and builder support from the Hyperliquid ecosystem.

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

For hackathons and demo days

Your 2 minute demo

Home: meet Seyi, 29, an ICU nurse in Manchester, stopped out after a night shift and back in 11 minutes later. -$184.
Review: answer three questions, close the file, and see the fills tag it a revenge entry.
Review: pick the green SOL trade and see a moved stop tagged as a mistake despite the profit.
Journal: case files with encrypted answers, then dispute a tag.
Month: repeat mistakes fell from 34% to 12%; Pro unlocks the Base attestation and share card.
Playbook: the Sunday digest turns the top repeat mistake into a rule, gated behind Pro.
Owner Revenue: change the Pro price in the paywall editor and preview the user Plans screen.
Owner Disputes and Roadmap: resolve Seyi's dispute, then request the v2 coach dashboard.

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

Most traders repeat the same few mistakes, revenge entries, moved stops, oversizing, but never review trades consistently. Journals feel like homework, and judging trades by profit teaches the wrong lessons.

What exists and what is new

Offchain trading journals like Edgewonk and Tradervue already do post-trade reviews, and BausBank vtr-core anchors decisions onchain. Research did not find a product tying short reviews to onchain fills with improvement attestations. Research verdict: rare, medium novelty. The review method itself is standard; what is new is fill-linked process tagging and a private journal with a public, attested improvement score.

The data it runs on

Closed fills read from public Hyperliquid, Solana and Base activity for the user's wallet, the user's answers and notes (encrypted on device), process tags, and monthly scores.

1.The mission

Turn every closed trade into a lesson, and let people prove they are getting better without exposing their journal.

2.Why people can't resist it

Two minutes, every close Three tap questions while the trade is fresh, one for tiny scalps.

A green trade can be a mistake It tags process against your plan, so luck does not hide bad habits.

Sunday rule Each week your top repeat mistake becomes one rule in your playbook, checked against your fills.

3.How it works for real

Read-only wallet link: The user connects a wallet or pastes an address; no signing permissions. Fills come from the Hyperliquid info API and public Solana and Base indexers.

Trade builder: Groups fills into trades with entry, exit, size, stop moves and timing relative to previous stops.

Review prompts: Push notification on close with three questions; a small model (for example Claude Haiku tier) compares answers with the fills and proposes a process tag.

Private journal: Answers and notes are encrypted on device and synced as ciphertext. Only the user can read them.

Monthly attestation: An EAS attestation on Base records the month's repeat error rate, review count and a hash of the reviews. No trades, notes or PnL are published unless the user chooses.

Digest: Sunday digest with top repeat errors and a suggested rule, verified against next week's fills.

4.Cost per use and pricing

Per review: a small model call of about 1,000 tokens costs a fraction of a cent. A Base EAS attestation is typically under 1 cent in gas. Example month for 1,000 active users doing 40 reviews each: about $40 to $80 in model calls, about $10 in attestation gas, plus indexer and hosting of roughly $50 to $100.

Free $0

Reviews on up to 30 closes a month, one chain, basic tags.

Pro $9 a month

Unlimited reviews, all chains, monthly attestation, playbook rules and the Sunday digest.

Coach $29 a month

Share a read-only process report with a mentor or trading group, with the user's consent.

5.Growth loop

Attested improvement cards are shareable without exposing PnL, which suits trading groups and mentors. Coaches invite students. The weekly rule loop keeps users coming back on Sundays.

6.Risks and guardrails

Not financial advice: The app measures process, not outcomes, and must never suggest trades or imply better reviews mean profits.

Privacy: Wallet addresses link to public trades. Notes stay encrypted and attestations hold only scores and hashes, never journal text.

Gaming the score: Users could answer dishonestly. The fills decide the tag, and disagreements are logged.

Wrong tags: The model can mislabel a trade. Users can dispute a tag; disputed tags are excluded from the score.

Encouraging trading: Streaks must reward reviewing, not trading more. Rest weeks never break a streak.

OWNER PLAYBOOK

Own it, then chart your voyage

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

Why own Post Mortem

Post Mortem asks a trader three quick questions after every closed trade, tags the mistake, and builds a monthly report of their top repeat errors with onchain proof of improvement. On a big journaling app, the platform owns the trader's history, data and subscription. Own it, and your brand sits on every review, the subscriptions are yours, and trading communities run their members' journals through you.

What’s stopping you?

“Will traders actually do reviews?”

Many skip them. That is why it is two minutes and three questions, triggered right after a fill. Keep it short, show progress monthly, and accept that maybe a third of users stick. Those are your customers.

“Is this financial advice?”

No. It asks the trader about their own trades and shows patterns. It never suggests trades. Keep the copy clear about that.

“I can't code.”

Fill import from Hyperliquid, Solana and Base, review prompts and reports come built. You edit questions and branding. New exchanges later need a developer.

“Is my users' data safe?”

Fills are public chain data, but notes are personal. Keep notes private by default and only publish what users choose to attest.

“Is it really mine?”

Yes. Your domain, your git, your subscribers, and the attestation contract deploys from your wallet.
