Previous steps to test the protocol:

1. Add and configure mumbai-testnet in your metamask wallet https://docs.polygon.technology/docs/develop/metamask/config-polygon-on-metamask/
2. Order MATIC tokens from faucet polygon https://faucet.polygon.technology/
3. Order AAVE faucet USDT tokens https://staging.aave.com/#/faucet
4. Add the UCP token contract to our metamask
5. Enter the site https://nrdzlizkmtj3.usemoralis.com/ and connect metamask in the mumbai network
6. Select any of the available products and accept the transaction
7. After accumulating the UCP tokens, at the bottom of the page, place the amount of UCP you want to exchange for USDT and claim cashback.

What is the Universal Cashback Protocol?

Universal Cashback Protocol was born as a decentralized solution for the cashback service using smart contracts, without intermediaries, using UCP (Universal Cashback Protocol) as token. The initial proposal developed works as follows: Affiliate companies can generate rewards with UCP tokens for the purchase of products, by accumulating UCP for purchases, it allows the user to exchange UCP tokens for USDT and buy more products.

General objectives:

• Promote the inclusion of people without technical knowledge in the Crypto economy through granting Cashback benefits in a simple way.

• Adopt Blockchain technology in everyday use cases.

• Expose to the general population the benefits and options obtained from decentralization.

What does this project contribute to the community?

We believe that everyone wins: The idea is that more people can approach the ecosystem of Blockchain and cryptocurrencies in a more friendly way. And all people make purchases of different products on a daily basis. Consumers: they will be happy to make a profit on their purchases. Companies: we provide the tools for a simple cashback process avoiding bureaucracy and technical knowledge. It may sound utopian, but we believe that with this project we are contributing to build freedom, and for us that is priceless.
