What is sarafis?

As an AI language model, I can provide you with information about sarafis working in a particular context such as Islamic finance or money exchange.

Sarafis are money changers in the Islamic finance industry who conduct transactions in compliance with Shariah law. They help investors exchange currencies or assets with other investors or clients in a transparent and efficient manner.

In some parts of the world, sarafis also operate as a part of the informal economy helping people to exchange currencies or make remittances to other countries. However, such unregulated transactions may not always be legal and can lead to fraudulent activities.

The history of sarafis can be traced back to the medieval Islamic civilizations where they played a crucial role in facilitating trade and commerce. In modern times, the industry has evolved, and sarafis now operate using advanced technology such as blockchain to make transactions more secure and transparent.
