The Fasttoken (FTN) cryptocurrency has its own blockchain, FCRC20, and through the FTNSCAN explorer, you will find that the transaction indeed took place three days ago, as mentioned by the OP via Block 3374861.

According to CMC, FTN is already listed on many exchanges, such as Gate.io, MEXC, and Bitget. I have checked the Fulgurpay website, and it is clearly an exchange platform designed to target FTN token investors. However, I could not find any popularity around this platform in search engines, sufficient reviews, or any connection to the Fasttoken project, which also has its own exchange platform.
