Crypton is a Tor-native service providing temporary, anonymous phone numbers for SMS verification, with a strict focus on privacy through its Monero (XMR) only payment policy. The platform allows users to rent a number for a set period to receive verification codes for various online platforms without linking their real identity. By using Monero, Crypton ensures that the payment itself cannot be easily traced on a public blockchain, offering a higher degree of financial anonymity compared to Bitcoin-based services.
