### PolkaSend is a Mobile-First wallet, cash out ramp and Point of Sale Superapp. We combine TradFi through Rapyd with Web3 to improve Financial Inclusion in Mexico and LATAM ## Category: Web3/Blockchain Tooling, Moonbeam Bounty 1 # Introduction and Problem Almost 4 years ago Vitalik Buterin, co founder of Ethereum posted in twitter this message: At that time it grabbed the attention of almost the entire crypto space and the answers regarding that question were mostly a big “Not many if at all”. Of course, there have been isolated projects that try to work with the developed world with several big names attached, but not to much avail. Cryptocurrencies and blockchain technology from that time onwards has mostly been used by a few early adopters and some others, but were mostly already banked, educated people, even in the developing world. Now, let’s ask that same question today; How many unbanked have we banked by the year 2021? Despite having made great progress and having outliers like the country of El Salvador, outside of that, the progress is almost null. Most of the same people that are into crypto today have been in for years and are the same elite, educated, previously banked ones, it has not reached those who are not. We can say that because our team lives in one of those developing countries that countless projects try to portray as a target for financial inclusion, which is Mexico. And yes, Mexico is the perfect target as it is the largest issuer of remittances from the US and it will break $42Billion this year alone. Of course, remembering that the US is the biggest sender of remittances in the world. It is important to mention that, according to the World Bank, 65% of Mexican adults do not have any type of bank account and only 10% save through a financial institution, in addition to the fact that 83% of Mexican adults do not have access to electronic payment systems. These circumstances limit the potential of the sector to place the resources of savers in productive projects that generate economic development and well-being for the population. And crypto is not doing better than the legacy system, most of the users are people like our team, tech savvy with a certain degree of education and already banked. # Solution PolkaSend is a Mobile-First wallet, cash out ramp and Point of Sale Superapp. We combine TradFi through Rapyd with Web3 to improve Financial Inclusion in Mexico and LATAM System's Architecture: - All Moonbeam transactions are controlled through [web3.js](https://web3js.readthedocs.io/en/v1.8.0/) and [WalletConnect](https://walletconnect.com/) on mainnet. - Thanks to the Rapyd APIs we can manage users, checkout, swap and KYC of our app. (https://www.rapyd.net/) # Main App Screens: - In turn, through Rapyd and Moonbeam we can have total control of the movements and transactions of our account in both Crypto and Fiat. - Crypto - Fiat - The KYC of our application is controlled by Rapyd and to confirm it, the documents must match the user's registration. - Through Moonbeam we can also make transfers directly between Moonbeam Wallets. - First we must click on the pay button. - We must select if we want to Recieve or Scan/NFC (by default the app opens the Recieve option).
