1. Understanding C2C Trading
C2C trading, or Customer-to-Customer trading, is a transaction model where users can directly buy and sell crypto assets with fiat currency through a website or app, without the need for a third-party fund intermediary. In this model, buyers and sellers exchange cryptocurrencies and fiat directly on an online marketplace. The platform only provides services such as ad listings, trade matching, intent connection, and escrow, without acting as a financial intermediary or counterparty.
In the C2C model, sellers post ads and deposit their crypto assets with the platform. Buyers select suitable ads to initiate trades and make payments using fiat currency. After payment is confirmed, the platform releases the crypto assets. Throughout the process, the platform does not hold users’ funds but provides trust assurance at a technical level.
The C2C trading service provided by AstralX covers trading methods, operational procedures, key terminology explanations, and compliance risk reminders, helping users quickly understand and safely conduct fiat-to-crypto transactions.
