Extracting your earnings from PolyGram is simple — since your USDC sits on the Polygon blockchain, you'll find several convenient pathways to liquidate or reinvest your funds. Below we walk through each option in detail.

Understanding Your USDC Balance

Once your prediction market bets settle favourably, USDC deposits directly into your PolyGram account on Polygon. From there, you have the flexibility to:

  • Continue placing trades on PolyGram itself
  • Move funds to your own self-hosted wallet
  • Send to a major exchange and swap for traditional currency
  • Leverage PolyGram's built-in fiat gateway for immediate bank deposits

Method 1: Fiat Off-Ramp (Bank Transfer)

The simplest choice for newcomers seeking direct bank access:

  1. Open Wallet → Withdraw within PolyGram
  2. Choose "Bank Transfer" or "Fiat Off-Ramp"
  3. Supply your banking credentials (IBAN in Europe, ABA routing and account in North America)
  4. Specify your desired amount in USD/EUR/GBP
  5. Funds settle within 1-3 business days

Fees: Roughly 1-2% for currency conversion, plus applicable bank charges

Method 2: Withdraw to Crypto Exchange

Ideal for those seeking optimal exchange rates when converting to fiat:

  1. Obtain your Polygon USDC receiving address from your chosen exchange (Coinbase, Kraken, etc.)
  2. In PolyGram, select Wallet → Withdraw → Crypto Withdrawal
  3. Paste the exchange address and ensure Polygon is selected as the network
  4. USDC appears on the exchange within approximately 5 seconds
  5. Trade USDC for USD/EUR directly on the exchange platform
  6. Request a bank withdrawal from your exchange account

Fees: Minimal Polygon gas cost (~$0.01) + exchange trading spread

Method 3: Self-Custody Wallet

Maintain complete ownership and control of your USDC:

  1. Retrieve your Polygon address from MetaMask, Trust Wallet, or a hardware device
  2. Initiate a withdrawal from PolyGram to this address
  3. USDC arrives instantly — no third parties involved

Once in your personal wallet, you're free to interact with decentralised finance applications, transfer across different blockchains, or simply hold your assets indefinitely.

Fastest Withdrawal Path (For Impatient Winners)

  1. PolyGram Wallet → Withdraw → Enter Coinbase deposit address (Polygon network)
  2. Funds arrive on Coinbase in roughly 5 seconds
  3. Immediately exchange USDC → USD on Coinbase
  4. Bank transfer completes: 1-2 business days (no charge with Coinbase One membership)

FAQ

Is there a minimum withdrawal amount?
Crypto withdrawals have no floor. Fiat off-ramps typically require a minimum between $10-25 based on your payment processor.
Are withdrawals taxable?
Simply withdrawing USDC generally carries no tax consequence — the taxable moment occurs when you win the prediction market bet (capital gain realisation). Always consult your local tax advisor regarding your specific circumstances.
How do I know my withdrawal is secure?
Every withdrawal executes as a transparent transaction on the Polygon network. You can always confirm completion by searching your transaction ID on Polygonscan.com.
