Takk Token

Blockchain app using Etherium Smart Contracts, Solidity, and ERC721.

Takk is an ERC721 token that represents a moment of gratitude shared between two people.

A user(Q) who does a good deed receives 1 Takk as gratitude for the deed from another user(T). The user who did the good deed(Q) now has 1 Takk in their wallet and can use their Takk to pay other users as gratitude when the situation arises. (i.e. T paid Q 1 Takk for doing something good)

Features to Look Forward to:

• Second token feature : Hafna can be sent to users who do bad deeds
• Hafna will automatically remove 20% of user's Takk, then continues to remain in the user's account for 3 days
• During the 3 days, if more Takk is recieved while Hafna is present, 50% of the Takk will automatically be sent to the user who originally sent the Hafna (i.e. Q received a Hafna from T, now Q pays T 50% of Takk recieved in the following 3 days)
• Users can exchange x Takk to buy 1 Hafna to send to another

Demo

Example of a User's webpage with gratitude tokens in their wallet. Sending/transfering a gratitude token ID 3 in my wallet. Sending/transfering a gratitude token ID 5 in my wallet. My list of gratitude tokens after sending/transfering desired tokens. View of the receiver's webpage. Error message received upon attempting to create a token on your own account.
