Before exchanging ERC20-standard USDC for Revolut, it is important to understand the specifics of how blockchain networks and financial services work. The ERC20 standard operates on the Ethereum network and is used for a variety of digital assets. It is within this infrastructure that USDC has become widely used. Each transaction on the ERC20 network is confirmed on the blockchain. After funds are sent from the user's wallet, the transaction is confirmed, and the asset is recorded in the system. Only then can the service begin converting the digital asset into EUR. The exchange process through the GroshX service begins with the creation of a request: the client specifies the required amount, Revolut details, and the cryptocurrency address for sending USDC. After that, the system generates the details for the transfer. When the user sends USDC from their wallet, a transaction occurs on the ERC20 network. Next, the service performs an internal check of the receipt of funds. After confirmation, the automatic exchange is launched and the digital asset is converted into euros. After the transaction is completed, the money is transferred to Revolut, and the customer can use it for payments, transfers, or storage in their account balance.
