How to use PolyBanca, step by step

You need four things: a Polymarket account with USDC/pUSD balance on Polygon; the address of your proxy wallet — not the MetaMask one; your license; and a modern browser.

Find the proxy address on polymarket.com: open the user menu and pick “Copy proxy address”. That is the account Polymarket operates for you on Polygon — the one that holds your tokens and your history.

The license comes from the 7-day free trial on this site’s home page: the form writes the Telegram message for you to send, and the license comes back to you.

On a phone, add the app to the home screen (PWA). It is the same app, just in your pocket.

The main path is the activation link: open it in the browser and the license activates itself — there is nothing to type. The URL is cleaned right after, so it does not stay in your history nor leak to another site.

Lost the link? The top bar has the fallback: “Paste license” opens a box where you paste the license text (it starts with LIC1. and has ~271 characters — the counter tells you if the paste was truncated), or you import the .txt file.

Click “Save and validate”. The check is local: the app verifies the signature, the expiry date and the wallet limit on your own device. Nothing of your balance ever leaves it.

Without a valid license the app runs in read-only mode and the sync stays blocked.

In Wallets, paste the 0x… proxy address, give it a name (e.g. “Demo Wallet”) and save.

The license allows 2 wallets — the second one becomes a tab at the top, next to the first.

The address is used to READ only. The app never moves money: no private key, no signing, no transfer.

Hit “Sync now”. The app fetches three things: your wallet’s public activity on Polymarket (buys, sells, redemptions); the market price of each position (the CLOB, and the Gamma catalogue when needed); and the pUSD balance on-chain on Polygon.

The first sweep takes 10–30 s — it has to walk the whole history.

Nothing is uploaded: the app only reads public data and the chain.

The home screen is the summary: the book (cash plus positions at market price), realized and unrealized P&L, accumulated ROI, the cash curve and the deposits/withdrawals.

In this demo: cash 26,0983 pUSD (R$ 139,08), realized P&L +2,8670, unrealized +0,2263, total +3,0933, ROI +7,73%, deposits 40,0000 and withdrawals 0,0000.

Every value in reais comes with the USD/BRL rate next to it (in the footer of every screen): the amount in reais is always pUSD × the rate displayed. The rate is only a display conversion — the book itself is always in pUSD.

Each row is one market: the title, the side (Yes/No), the size, the average price, the current price, the realized and unrealized P&L, and how much of the book that position is.

The allocation uses the weighted average price of the buys — not FIFO, not LIFO.

In the demo there are 17 positions: 9 open and 8 closed.

Every trade the public API returned: date and time in UTC, type, side, market, outcome, size, price, the amount in pUSD and the transaction hash.

The hash is how you check the operation on the Polygon explorer — it is the same hash that shows up in the audit table.

There are filters (text, date range, type, side) and a CSV export of the page.

The analysis breaks the result down six ways: by market, by event, by category, by side, by weekday and by hour band.

It shows the current drawdown (what is happening right now) and the biggest drawdown of the period (the worst stretch), plus the win/loss sequences.

The unit is the trade, and the unrealized P&L enters diluted by the size of the position.

A category with fewer than 5 operations with P&L gets a “small sample” warning — the app does not draw a conclusion from it.

The calendar shows the evolution of the book day by day: a 7-column grid, today highlighted, and the detail of each day with the variation in % and in pUSD (and in reais).

Careful: the recorded market price is today’s — Polymarket does not give a price history per operation. So the book of past days is a RECONSTRUCTION (exact only on the last day) and the app warns about that on the screen.

Where the market price is missing the value is “unknown” (—), never zero.

The audit confronts the on-chain pUSD balance (Polygon) with the balance calculated from the operations.

In the demo: on-chain 26,0983 × calculated 26,0983 ⇒ delta 0,0000, with the “reconciled” badge. This is the number that proves the app does not make money up.

The sweep goes block by block, and the public Polygon RPC limits the window per call ⇒ covering the whole history may take a few syncs.

The movements screen splits the money into three classes: deposit (money coming in), operation (buy, sell or redemption) and withdrawal (money going out).

The account closes on the screen: 40,0000 − 13,9017 − 0,0000 = 26,0983 pUSD, exactly the on-chain balance.

An on-chain transfer is never counted as a deposit — it is evidence, not income.
