USDC, which stands for USD Coin, is a stablecoin issued on the Ethereum blockchain. As an ERC-20 token, USDC transactions on the Ethereum network may incur gas fees. Gas fees are the costs associated with processing transactions on the Ethereum blockchain, and they are paid in Ether (ETH). Therefore, when you send or receive USDC on the Ethereum network, you may need to pay gas fees to miners to confirm and record the transaction on the blockchain.
