The Mission

Reading is the first step toward ownership

Tsubaki isn't just a reader. It's an engine that turns every page you turn into a petal on-chain — verifiable, permanent, yours. Bloom your collection, claim hidden art, and own the journey.

Petal Tracking

Every page you turn drops a petal. Every chapter you finish is sealed into the chain. Your reading bloom begins with the very first word — and never fades.

Bloom Relics

Unlock limited camellia cover art and hidden pages that take root permanently in your garden. Rare relics no other reader can pluck from you.

Sealed Proof

Your progress is rooted in the Solana ledger. Hardened milestones — sealed, signed, and impossible for anyone to wilt or take away from you.

On-Chain Milestones

Immortalize Your Progress

Hana is a Solana program that records verifiable milestones of reader participation — tied permanently to a wallet. If it's not a milestone, it doesn't go on-chain.

Chapter Unlock Records

When you unlock a chapter using $TSUBAKI, a PDA (Program Derived Address) is created on Solana, proving you were there from Day 1.

  • Immutable timestamp of unlock
  • Verifiable reader address
  • Cryptographic proof of access

Mastery Verification

Finish a volume to mint a non-transferable achievement record. Your library is your reputation.

  • 100% Completion Badge
  • On-chain reading analytics
  • Exclusive community access

First 1,000 Reader Badges

When a chapter drops, Hana tracks a global counter. If you're among the first 1,000 readers to unlock it, you earn a verifiable Early Reader badge.

  • Global unlock counter per chapter
  • Automatic badge minting
  • "I was here day one" — provable

Support Tier History

When a reader tips or supports a creator, it becomes on-chain reputation. Visible participation. Portable across any app that reads the program.

  • Track total support per creator
  • Automatic tier calculation
  • Portable creator reputation

Why On-Chain

Because milestones become identity

You don't put everything on-chain. You put the things that mean something.

01

Portable Identity

Your reading achievements travel with your wallet. No lock-in. No silos. Cross-platform by default.

02

Cross-App Recognition

Any front-end can read your progress. Your milestones are not trapped in one app — they're visible everywhere.

03

Creator Transparency

Real engagement numbers, not inflated analytics. Verifiable support metrics that creators can trust.

04

Composability

Other programs can gate rewards, airdrops, or access based on milestones. Your reading unlocks real value.

Beta Feature

Tsubaki AI — chat that knows your stack

A pinned launcher on the home feed opens a full-screen assistant tuned for readers and wallets: natural language first, confirmations before anything hits-chain.

Ask for something to watch or read tonight, catch up after a hiatus, resume where you stopped, surface recommendations, set price reminders, swap or bridge with quoted routes, tip a creator—you describe it; Tsubaki AI routes the request through tooling with your wallet context. Chat threads can sync when you're signed in so you aren't starting from scratch on a new device.

Under the hood, responses use fast inference (including Groq-hosted models with tool routing) tied to Solana portfolio data and DEX quoting, alongside optional alerts and lightweight long-term preferences you control. Unlocking Tsubaki AI is tied to holding $TSUBAKI in-app; risky actions stay approval-gated in the client—no silent signatures.
