Opening an account on PolyGram is considerably quicker than establishing a conventional brokerage relationship. Within approximately 5 minutes, you can complete your account setup and execute your initial prediction. Below is a comprehensive breakdown of all funding options at your disposal.

Method 1: Credit or Debit Card (Fastest)

PolyGram's integrated fiat gateway accommodates all major payment cards across most jurisdictions. Here's how it works:

  1. Launch PolyGram via Telegram
  2. Go to Wallet → Deposit
  3. Choose "Card Payment"
  4. Specify your deposit value in USD/EUR/GBP
  5. Verify your card details
  6. USDC credits appear in your wallet within 30-60 seconds

Fees: Approximately 2-3% card processing charge (typical for digital asset on-ramps)

Method 2: USDC Transfer from Exchange

Already holding USDC on a major exchange? This route typically offers the lowest cost for depositing funds.

  1. Access Wallet → Deposit within PolyGram
  2. Retrieve your Polygon wallet address for deposits
  3. From your exchange account (Coinbase, Kraken, Binance), request a USDC withdrawal to the Polygon network
  4. Ensure you select "Polygon" as your destination chain — avoid Ethereum mainnet due to substantially higher costs
  5. Your USDC will appear within 30-120 seconds

Fees: Your exchange's withdrawal charge (usually $0-5) plus negligible Polygon transaction costs

Method 3: Self-Custody Wallet Transfer

Should you already possess USDC in MetaMask, Trust Wallet, or another Polygon-enabled wallet application:

  1. Obtain your PolyGram deposit address via Wallet → Deposit
  2. Access your wallet application and transmit USDC on Polygon to this address
  3. Authorise the transaction through your wallet interface
  4. Your USDC will be credited within 2-5 seconds on the Polygon network

Fees: Polygon network charges exclusively — ordinarily under $0.01

Method 4: Ethereum Bridge (Advanced)

For those with USDC residing on the Ethereum mainnet, the Polygon Bridge enables you to migrate your assets to Polygon:

  • Visit bridge.polygon.technology
  • Move your USDC from Ethereum across to Polygon (approximately 15-20 minutes required)
  • Subsequently transfer from your Polygon wallet into PolyGram

Fees: Ethereum network charges (presently between $5-30 based on current network activity)
