On Nimb, reading the map needs nothing: no account, no wallet, no sign-up. Trading needs three things: a location where Polymarket allows new orders, a self-custody wallet, and pUSD or USDC on Polygon. Setup takes about 15–30 minutes the first time.
Nimb is an independent map of Polymarket prediction markets. It reads Polymarket's public data, and when you trade, it sends your order to Polymarket from the wallet you connect. Nimb never holds your funds: every order is signed in your wallet and settles on Polymarket. Nimb is not affiliated with Polymarket.
What do you need before you can trade a prediction market?
To read markets, you only need a browser. Open the map and every circle, price, holder and theme is there. To trade, you need:
| What | Why | Where to read more |
|---|---|---|
| An eligible location | The US, the UK, France and about 35 other countries are close-only: you can close positions but not open new ones. Sanctioned places are blocked. | Restricted countries |
| A self-custody wallet | Your wallet signs every order. Nimb never sees your keys. | Create a crypto wallet for Polymarket |
| pUSD or USDC on Polygon | Polymarket trades settle in pUSD, a USDC-backed token on Polygon. | Fund your wallet with USDC on Polygon |
Do I need a Polymarket account to use Nimb?
No. You do not sign up on polymarket.com. When you first connect a wallet to trade, Nimb asks Polymarket to set up a Polymarket Deposit Wallet for your address. Deposit Wallets have been Polymarket's default account type for wallets deployed since 4 May 2026, and each one stays controlled by the wallet that signs for it.
Can I use Nimb without a wallet?
Yes, for everything except trading. The map, the market panel, the /markets pages and these docs are open to everyone, in every country, with no wallet. You need a wallet only when you press Buy.
How long does setup take?
The five steps below take about 15–30 minutes in total for a first-timer. Most of the time goes into step 3, because moving money onto Polygon depends on where it starts.
- Check you are eligible: about 1 minute.
- Create a wallet: about 5–10 minutes, including writing down the recovery phrase.
- Fund it with USDC on Polygon: about 5–30 minutes. A transfer from another wallet on Polygon arrives in a minute or two; buying on an exchange and withdrawing can take longer.
- Connect it to Nimb: about 2 minutes, two or three wallet pop-ups.
- Read the market, then place a small order: about 5 minutes.
Step 1: check you are eligible
Polymarket lists the United States, the United Kingdom, France and about 35 other countries and regions as close-only: you can close positions you hold but not open new ones. Among them, at the time of writing (2026-11-07), are Germany, Italy, Belgium, Poland, Australia, Singapore and four Canadian provinces. Sanctioned places, such as Cuba, Iran, North Korea and Syria, are blocked completely.
Nimb checks Polymarket's geoblock endpoint from your browser before every order. If your location is restricted, the order button does not open new positions. Do not use a VPN to get round the check: it breaks Polymarket's terms. The full list and how the check works are on who can trade from Nimb.
Step 2: create a wallet
Nimb works with browser wallets (MetaMask, Rabby, Coinbase Wallet) and with WalletConnect, which links a mobile wallet by QR code. Install one from its official site or app store, create a new wallet and write the recovery phrase on paper.
Three rules matter more than any other: never type your recovery phrase into a website, never share it with anyone, and remember that Nimb will never ask for it. Consider a dedicated wallet that holds only what you plan to trade. Details, a comparison table and safety checks are on how to create a crypto wallet for Polymarket.
Step 3: fund it with USDC on Polygon
Polymarket uses pUSD as collateral: a standard token on Polygon, backed one-to-one by USDC. You rarely handle pUSD yourself. Polymarket's bridge gives you deposit addresses; USDC and many other tokens sent there, from Polygon, Ethereum, Solana, Bitcoin, Tron and other chains, are converted to pUSD automatically. Minimums are about $2 on Polygon and most layer-2 chains, $7 on Ethereum and $9 on Bitcoin and Tron, as of 2026-11-07.
The most common mistake is sending on the wrong network. Read how to fund your wallet with USDC on Polygon before your first deposit, and start with a small test amount.
Step 4: connect it to Nimb
Press Connect wallet at the top of the map, choose Browser wallet or WalletConnect, and approve the pop-ups. The first time, you switch to Polygon, sign a message that proves you control the wallet, and approve a one-time setup of your Polymarket trading wallet. None of these costs gas.
Nimb cannot move your funds. It has no access to your keys and every order needs your signature. What each pop-up means is on how to connect your wallet to Nimb.
Step 5: read the market, then place a small order
Before you trade, read the market. Open a circle on the map; the panel shows the reading, a one-sentence summary such as "Traders see a 41% chance…, down 4 points this week", along with the price chart, spread, money flow and largest holders. How to read a market explains each part, and the Before you trade checks flag a wide spread, a thin book or a market that resolves soon.
Then use the order ticket in the same panel: choose Yes or No, type one amount in dollars, check what you receive if you are right and the break-even chance, and sign in your wallet. The amount you type is all-in: fees are folded into the shares, never added on top. The minimum order is $1. For a first order, $1–$10 is enough to learn how the ticket, the signature and the portfolio work, without much at stake. A worked example is on place your first order.
Prediction markets are risky: you can lose your whole stake. Prices can move fast, books can be thin, and markets can resolve in ways you did not expect. Nothing on Nimb is financial advice. Read the risks of prediction markets before you trade real money.
Is Nimb available in my country?
Reading is available everywhere. Trading follows Polymarket's rules: if Polymarket's geoblock says your location cannot open new positions, Nimb cannot place them either. See restricted countries.
From reading to execution
Read and execute is Nimb's workflow: read the market in the analysis panel, then act on it in the order ticket, in one place. Setup is a one-off; after it, going from reading to execution is one panel and one signature. Read how the ticket works on the order ticket, or start with the map and trade later, or not at all.
