What you need

▾

Your email inbox, open in another tab. Polymarket sends codes there.
A way to pay (only for Level 2). Polymarket has the most common options: card, Apple Pay, Google Pay, Revolut Pay and PayPal. Crypto works too.
A computer, Windows or Mac. The trading app is a desktop app.
About ten minutes, start to finish.

Before you start: check the rules

▾

Polymarket is not available everywhere. During sign-up you confirm you accept the Polymarket Terms of Use and that you are not in the U.S. or another restricted region. Read them first. You will also connect Traderline, so read the Traderline Terms & Conditions, including the Polymarket tab. In step 11 you additionally accept Magic's Terms of Service, linked on that screen.

Use of these platforms is only permitted where allowed by law, and checking that for your country is your responsibility.

Level 1 of 3

Create your account

Four small steps. At the end of this level your account and your wallet exist.

Open Polymarket

▾

Click the button below to open Polymarket, then click the blue Sign Up button in the top right corner of the page.

Open Polymarket →

Enter your email

▾

Type your email address and click Continue. If you prefer, use Continue with Google instead. Ignore the other icons, you don't need them.

Welcome to Polymarket window with the email field highlighted — **What you'll see:** the Welcome to Polymarket window. Email field highlighted in red.

Enter the code from your inbox

▾

Polymarket emails you a 6-digit code. Open your inbox, copy the code, and type it in. No email after a minute? Check your spam folder.

!Polymarket staff will never give you a code to enter. If someone sends you a code and asks you to type it, it's a scam.

Window asking for the 6-digit code sent to your email — **What you'll see:** six empty boxes for the code, secured by Magic.

Pick a Polymarket username and accept the terms

▾

Type any username. You can change it later. Then tick the first box, highlighted below: it means you accept the Terms of Use and confirm you are not in the U.S. or a restricted region. Click Continue.

That's it. Your account and your wallet now exist.

Level 2 of 3

Add money

You can deposit any time, but do it before Level 3: connecting Traderline requires balance in the account.

Choose how to pay

▾

Click Deposit at the top of Polymarket. In the window that opens, choose the Use Cash tab and pick your payment method. Card is the most popular. Apple Pay, Google Pay, Revolut Pay and PayPal work exactly the same way.

Prefer to deposit crypto instead?▾

Choose the Use Crypto tab. Transfer Crypto gives you a deposit address (minimum $10), and Connect Exchange links an account like Coinbase or Binance. If none of this means anything to you, just use the Cash tab above.

Choose the amount and pay

▾

Type how much you want to deposit and click Continue. The window shows your money converted to USDCe, the digital dollar your Polymarket balance is held in. 1 USDCe is worth about 1 US dollar. Any processing fee is shown before you confirm, so there are no surprises.

Tick the boxes and reveal your key

▾

What is Magic? Magic is the company Polymarket uses to create and protect the wallets behind email logins. When you signed up in Level 1, Magic generated your wallet's private key and has been guarding it ever since. This page is Magic's official way of handing the key to you to use in apps, and only to you.

Tick all three boxes. They are Magic’s conditions for the handover, including its Terms of Service, linked right there on the page. Then click Reveal Private Key.

!If the page asks you to log in first, use the same email from Level 1. Magic emails you a code, exactly like the sign-up did.

Copy the key

▾

Click Copy. If Copy is greyed out, click Reveal first, then Copy. You don’t need to read it, write it down, or memorize anything. The computer is holding it for you now.

!Never screenshot the key, never paste it in a chat, never read it to anyone. You are the only person who should ever touch it.

Magic Wallet Private Key page with the Copy button highlighted — **What you'll see:** your key in the box (blurred here on purpose). The red box marks Copy.

Paste it into Traderline and connect

▾

Go back to the Traderline app. Click the Signer Private Key field and paste: Ctrl+V on Windows, Cmd+V on Mac. A green box appears: Logged in as Polymarket Proxy, pUSD available. That’s your account, recognized.

Tick Remember on this device if this is your own computer, so you don’t have to paste the key again next time. Then click CONNECT.

Your key stays with you. It traveled from Magic's official page straight into the Traderline app on your computer. That's the whole journey. Your money doesn't move either: your balance and your positions stay on Polymarket, held by the exchange, exactly where they were. Traderline is the cockpit, not the vault. And one rule, forever: Traderline staff will never ask for your key. Anyone who does is a scammer.

**What you'll see:** the key as dots, the green confirmation, and CONNECT in the red box.

If something goes wrong

▾

The code email never arrives: Check your spam folder first. Still nothing? Close the window, click Sign Up again and a new code is sent.
Sign-up says your region is blocked: Polymarket is not available in every country, and account creation tells you immediately. There is no workaround Traderline can offer, and trying to bypass the block breaches Polymarket's terms.
You paid but the balance shows zero: Card payments are usually instant but can take a couple of minutes. Refresh the page. If it still shows zero after 15 minutes, contact Polymarket support with your payment receipt.
The Magic page asks me to log in: Use the same email from Level 1. Magic emails you a code, exactly like the sign-up did.
Copy is greyed out: Click Reveal first, then Copy.
The green "Logged in" box never appears: The key didn't paste completely. Go back to Magic, click Copy again, paste again. Never type it by hand.
CONNECT won't go through: Connecting requires balance in your Polymarket account. An empty account can't be connected. Deposit in Level 2, then try again.
Connected, but the balance shows 0: Your deposit may still be processing on Polymarket. The money lives on Polymarket; Traderline only displays it. Give it a few minutes and refresh.
Still stuck: Ask in the Traderline Discord. Real people, fast replies. Never accept DMs on Discord from users who appear to be from Traderline or Polymarket, it’s a known scam. Polymarket and Traderline will never DM you first.

You're in

Connected. The ladder is yours.

Pick a Type like Sports at the top, search for a market, and trade. Same skills, new exchange.
