SHAKA reads the receipts you already have and shows them as something you could own: shares of a real stock token on Robinhood Chain. It also reads Zcash mining odds and your own wallet. Everything runs in your browser, on public data.
Why SHAKA exists
You pay for rides, food, fuel and games every week. The brands you spend on are public companies. SHAKA makes that visible: each receipt becomes a number of shares at today's price, and a list of receipts becomes a picture of what your spending would own.
Reading a receipt
- Take a photo or a screenshot of a receipt, or type the total and the shop.
- Text recognition (tesseract, in your browser) reads the lines. SHAKA looks for the total next to words like TOTAL, AMOUNT or JUMLAH and picks the most plausible amount.
- You check the total, the currency and the merchant, and fix them if needed.
- The amount is turned into US dollars at today's rate, and the merchant picks a stock token.
- The desk shows the shares at the live price. Add it to your list if you like; the list stays on this device.

The harmonic habit
slicek = receiptk / k, ∑k≤n slicek = receipt · Hn ≈ receipt · (ln n + γ)
- k: the position of the receipt in your list (1, 2, 3…)
- Hn: the harmonic number, 1 + ½ + ⅓ + … + 1/n
- γ ≈ 0.5772, the Euler–Mascheroni constant
The desk shows two totals for your list: everything as shares, and the harmonic slice. The second one grows forever, but each step is lighter than the last. It is a way to look at spending, not a plan or a payout.
Zcash odds
P(block) = 1 − e−λ, λ = h · t / (Hnet · 75 s)
h is the hashrate you enter, t the run length, Hnet the live network hashrate and 75 s the Zcash block time. A block pays 1.5625 ZEC today, 80% of it to the miner. Most runs find nothing: the desk shows the real odds, not income.
Your wallet
Connect MetaMask, Rabby, Coinbase Wallet, OKX or Trust. SHAKA only asks for your address: no signature, never a seed phrase. It reads ETH, $SHAKA and every Robinhood stock token you hold, values them live and lists your recent activity. Logout is always one tap away.

What SHAKA is not
SHAKA does not refund receipts, pay out stock or run vaults. It shows numbers from public data. $SHAKA is a community token with no promise of profit.
