The process of exchanging USDC ERC20 for Visa Mastercard EUR through a crypto exchange usually consists of several stages. First, the user selects an exchanger through Obmify, where they can compare the conditions of different platforms and choose the most profitable exchange. After selection, a request for exchange is created, specifying the amount, bank card details, and the wallet address from which USDC will be sent. Next, the user transfers USDC from their wallet, after which a transaction occurs in the ERC20 network. When the service receives confirmation of the transfer, the exchange procedure begins. At this stage, USDC is converted to EUR, after which the funds are transferred to the Visa Mastercard. The user receives money in their bank account, where they can use it for payments, transfers, or cash withdrawals. In some cases, exchange services may require registration or KYC for large transactions. Such verification enhances the security of the deal and complies with the requirements of financial systems.
