You are sending funds **from Yourself to your Own wallet** — Polymtrade never holds or touches your money. We have zero access to your funds at any point. Your balance in Polymtrade is stored in USDC — a stablecoin pegged to the US dollar. There are two main ways to add funds: The easiest way to add funds — pay directly inside Polymtrade with a **debit or credit card**, or **Apple Pay**. No external app needed. On the main Polymtrade screen, tap your **email address** shown at the very bottom — this opens the **Account** panel.

In the **Account** panel, tap the **Add funds** button.

On the **Add funds to your Polymtrade wallet** screen, tap **Pay with card**.

MoonPay will open to process your payment. If this is your first time, you'll need to complete a one-time registration — see the [MoonPay](#moonpay) tab below for the full walkthrough. Enter the amount of USDC you want to buy, review the order, and confirm with your card or **Apple Pay**. The USDC will be credited to your Polymtrade wallet automatically. Send USDC to your Polymtrade wallet address from any app that supports crypto transfers. On the bottom bar, tap the **Deposit** icon (arrow pointing down into a tray) — this opens the **Select Network and Token** screen.

In the **Select Chain** dropdown, choose **Polygon** — it has zero fees on our side. Other supported networks: Solana, Ethereum, Binance Smart Chain, Base, Arbitrum, Optimism, World Chain.

In the **Select Currency** dropdown, choose **USDC**. You can also send USDT, DAI, WETH, WBTC, or USDC.e — they will be automatically converted to USDC.e on Polygon for trading.

Your deposit address appears under **Send USDC to Polygon wallet**. Tap the copy icon next to it. Always double-check the wallet address before sending. Sending to the wrong address means sending to someone else's wallet — those funds cannot be recovered. This is **your wallet** — you hold the private key and have full control. If you accidentally send an unsupported token or use an unsupported network to your own address, you can always recover the funds by [exporting your private key](/guides/import-private-key).

Open your app (Coinbase, Revolut, or any other), paste your Polymtrade wallet address, select the same network you chose above, and confirm the transfer. See the tabs below for step-by-step instructions from specific apps. Funds will arrive automatically — you don't need to do anything. Go to the **Portfolio** tab and you'll see your updated balance once the transfer is confirmed. If you've been waiting a while and nothing has appeared, tap **Deposit pending — check balance** to manually refresh. Use this only when needed.

*** MoonPay requires a one-time identity verification before your first purchase. The process takes about 5 minutes. If you've already registered, skip straight to [Step 11](#enter-the-usdc-amount). MoonPay opens with the **Terms of Use** screen. Review the terms and tap **Accept** to continue.

MoonPay will ask you a few questions to verify your identity. Tap **Continue** to begin.

Answer questions about your source of income and wealth. Select the options that apply and tap **Continue**.

Fill in your **first name**, **last name**, **date of birth**, and **nationality**. Tap **Continue**.

Choose your **country or region** from the list.

Confirm the country of residence shown is correct, then tap **Continue**.

Select the type of ID you'll use for verification — **passport**, **driver's license**, or **national ID card**.

MoonPay will explain the verification process: you'll need to take a photo of your ID document and then complete a face scan. Tap **Continue** to proceed.

Follow the on-screen tips for a successful face scan — good lighting, face centered, no glasses. When ready, allow camera access and complete the scan.

MoonPay is verifying your data. This usually takes less than a minute. Once complete, you'll see a **Profile verified** confirmation.

Enter how much USDC you'd like to buy. You'll see the total cost including fees. Tap **Continue**.

Review the order summary — amount, fees, and total. Enter your card details or select **Apple Pay**, then tap **Pay with card**.

Your bank may require **3D Secure** verification. Follow the prompts from your bank to authorize the payment.

Once the payment is processed, you'll see the order status change to **complete**. The USDC will be delivered to your Polymtrade wallet automatically.

Best for users in **Europe**. Sending crypto from Revolut is done through the main **Revolut** app (not Revolut X). The steps below guide you from Revolut X to the right place. Open the [**Revolut X**](https://revolut.com/referral/?referral-code=maryiaeozc!FEB2-26-AR\&geo-redirect) app. On the home screen tap **Withdraw**.

In the bottom sheet that opens, tap **Withdraw money** — To your other bank account.

Revolut X will show a message that cash withdrawals are handled in the main Revolut app. Tap **Open Revolut app**.

The main **Revolut** app opens. At the bottom bar tap **Crypto**.

You'll see a "Send crypto simply" intro screen. Tap the **Send crypto** button.

In the search field, paste the wallet address you copied from Polymtrade. Tap the **Send to 0x...** suggestion that appears.

Choose **USDC** as the currency. Below, select the account you want to send from — Revolut will automatically exchange your local currency to USDC. Tap **Done**. **Don't confuse POL (the coin) with Polygon (the blockchain).** Always select **USDC**, not POL.

On the **Select network** screen, choose **Polygon**.

Enter the amount of USDC you want to send. Verify the **Network** shows **Polygon**, then tap **Review transfer**.

Revolut will ask **Does this address belong to you?** — tap **Yes**.

On the **Address details** screen, make sure **My wallet** is selected. In the **Wallet** field, choose the wallet type — for example, **Phantom**. Tap **Save**.

Check the summary: recipient address, network (Polygon), amount, fees, and total cost. Tap **Confirm transfer**.

After confirming, you'll see the transaction status with **Request processed** and **Pending** steps — this is normal. The transfer is being submitted on-chain.

Open the **Activity** tab in the Revolut X app → **Transactions** to track the status.

Once done, the status changes to **Completed** with both steps green — **Request processed** and **Received by recipient's address**. USDC is on its way to your Polymtrade wallet.

Open Polymtrade and go to the **Portfolio** tab. Your updated USDC balance will be shown at the top. If funds are still processing, you'll see **Deposit pending — check balance** — tap it to refresh.

Best for users who already hold USDC in a **Phantom** wallet on the Polygon network. Open the **Phantom** app. On the home screen, tap **Send**.

On the **Select Token** screen, choose **USD Coin (USDC)**.

In the **To** field, paste the wallet address you copied from Polymtrade. Tap the **Paste from clipboard** suggestion that appears then tap **Next**..

Enter the amount of USDC you want to send. Check the summary: recipient address, network (**Polygon**), and network fee. Tap **Send** to confirm. Phantom may show a caution message if you haven't interacted with this address before — this is expected. Verify the address matches what you copied from Polymtrade, then proceed.

These steps work for most crypto apps and exchanges that support USDC on Polygon. Look for a **Send**, **Withdraw**, or **Transfer** option — it's usually on the main screen or in the wallet section. Search for **USDC** and select it. Look for the network selection option. Choose **Polygon** — it has the lowest fees. If Polygon is not available, check what networks your app supports and cross-check with networks available in your Polymtrade wallet. Choose any network that appears in both. The network must exactly match on both sides. Sending to the wrong network will result in permanent loss of funds. Paste your Polymtrade wallet address, double-check it, and confirm the transfer. Funds typically arrive within a few minutes. *** USDC is a stablecoin — 1 USDC ≈ 1 USD. There are no hidden fees on Polymtrade's side; transfer and conversion fees depend on your external app.
