The problem TokenMart solves

Brand Tokens provided after a certain transaction will be used on this brand alone which is not the case now as the platform tells where the tokens applies.It also helps the brand to retain their customers
Long trusted customers are taken with all the care in the world, provided by loyalty tokens which have even higher benefits than brand tokens.
Customers can verify at all times what is happening as their transaction is on the blockchain. It helps to build more trust as right now users can't see what is the process of token generation and further use.

Challenges we ran into

When to provide loyalty tokens to users and at what value.
Provide users with an intuitive dashboard to manage tokens, and view rewards, and token expectations if continue to buy.
Changing tokens allocation if window shopping is more. Integration of some tracks like hedera and Circle API Integration .
