Eaze: Make Payments without an internet connection.
Problem: During our travel to EthAccra, we couldn't pay for food in Togo because of a lack of internet connection and we didn't have their local currency to make the transactions.
At that moment we realized that our blockchain knowledge was useless because the natives didn't understand crypto and blockchain and we couldn't access the internet.
Solution: Introducing Eaze, a platform that allows its users to make payments anywhere in Africa without an internet connection, This is possible with the use of USSD and the Blockchain.
How it works:
Onboarding:
USSD PAYMENT:
Our Business Model:
TAM (Total Addressable Market ) - Africa has a total of 55.3 million cryptocurrency holders across 33 countries.
SAM( Serviceable Addressable Market ) - Our Target Users is 20% of our TAM which is 11 million users. These users make at least one transaction per day - which equates 11 million transactions.
Scalability Plans
