​
Transfer from Wallet

Send USDC from your crypto wallet (MetaMask, Uniswap, or any Web3 wallet) to SportToken.

​
Overview

If you have USDC in a self-custody wallet like MetaMask, Uniswap Wallet, or any other Web3 wallet, you can transfer it directly to SportToken. This gives you full control over your funds.

​
Requirements

  • A Web3 wallet (MetaMask, Uniswap, Rainbow, etc.)
  • USDC on Polygon network
  • Small amount of MATIC for gas fees (~$0.01)

​
How It Works

  1. Click the + DEPOSIT button in the header
  2. Select “Transfer from wallet”
  3. Connect your wallet (if not already connected)
  4. Enter the amount of USDC to transfer
  5. Confirm the transaction in your wallet
  6. Wait for network confirmation (1-3 minutes)
  7. Funds appear in your SportToken wallet

​
Network & Token Details

Important: You must send USDC on Polygon Network. Sending on other networks may result in loss of funds.
  • Token: USDC (USD Coin)
  • Network: Polygon (MATIC)
  • Token Contract: 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359

​
Fees

  • Network gas fee: ~$0.01 - $0.05 in MATIC
  • No platform fee for wallet transfers
  • Much cheaper than Ethereum mainnet

​
Getting USDC on Polygon

If you have USDC on Ethereum or another chain:

​
Option 1: Bridge

Use the official Polygon Bridge:
  1. Go to wallet.polygon.technology
  2. Connect your wallet
  3. Bridge USDC from Ethereum to Polygon
  4. Estimated time: 7-8 minutes
  5. Gas fees: ~$5-15 on Ethereum

​
Option 2: Exchange

Buy USDC directly on Polygon:
  1. Use a centralized exchange that supports Polygon withdrawals (Coinbase, Binance, Kraken)
  2. Buy USDC
  3. Withdraw to your wallet address on Polygon Network
  4. Much cheaper than bridging

​
Supported Wallets

Any wallet that supports Polygon network:
  • MetaMask (most popular)
  • Uniswap Wallet
  • Rainbow Wallet
  • Trust Wallet
  • Coinbase Wallet
  • WalletConnect compatible wallets
  • Hardware wallets (Ledger, Trezor)

​
Adding Polygon to MetaMask

If you don’t see Polygon network in MetaMask:
  1. Open MetaMask
  2. Click the network dropdown (top of the app)
  3. Click “Add Network”
  4. Select “Polygon” from the list
  5. Or add manually:
    • Network Name: Polygon
    • RPC URL: https://polygon-rpc.com
    • Chain ID: 137
    • Currency Symbol: MATIC
    • Block Explorer: https://polygonscan.com

​

  1. Wallet confirmation: instant
  2. Network confirmation: 1-3 minutes (usually ~30 seconds)
  3. SportToken processes deposit: automatic

​
Troubleshooting

Transaction pending for a long time?
  • Check Polygonscan.com with your wallet address
  • Polygon is usually fast - delays are rare
  • If stuck, the transaction may need more gas
Insufficient gas fee?
  • You need a small amount of MATIC for gas
  • Get MATIC from an exchange or bridge a small amount
  • Alternatively, some wallets offer gasless transactions
Sent on wrong network?
  • If you sent USDC on Ethereum, BSC, or another chain (not Polygon), contact support immediately
  • Include your transaction hash and wallet address
Transaction failed?
  • Check you have enough USDC + gas fees
  • Ensure you’re connected to Polygon network
  • Try increasing gas limit in advanced settings

​
Benefits

  • Low fees (just network gas)
  • Works with any Web3 wallet
  • Privacy - no KYC required for wallet transfers
