Project Overview

SentiPay is a non-custodial cryptocurrency wallet that allows transactions with multiple currencies, including Bitcoin, Ethereum, Litecoin, and many others, across different wallets (crypto and fiat). The SentiPay Wallet enables consumers, merchants, and investors to transact, store, swap, send, buy, and earn cryptocurrency through a single mobile application. It securely holds your private key and provides 100% control over your funds.

Project Requirements


The client aimed to develop a mobile wallet and launch it in South Africa's non-crypto market. Until now, there had been no means for users in the country to trade cryptocurrencies. The BloxBytes team created the SentiPay wallet, enabling users to purchase digital coins with their credit cards. The client requested a mobile wallet capable of handling multiple transactions involving both crypto and fiat currencies.


The challenge was to develop a mobile wallet that could manage funds and cryptocurrencies since the app’s primary goal was to launch SentiPay’s token and enhance its usability. Consequently, people could purchase cryptocurrencies with fiat money or dollars directly, bypassing traditional exchanges. One of SentiPay’s major hurdles was the fact that all significant exchanges adopt USDT as the standard currency for buying cryptocurrencies.

BloxBytes Solutions


As a technology partner, we developed SentiPay wallet which allows users to buy cryptocurrency with their credit cards. This platform converts South African Rands into desired cryptocurrencies and connects them to USDT. To facilitate trading on UniSwap, we created the app’s ERC-20 token, called ZARC. We designed the app with dual modes, consumer and merchant, so users could switch modes in seconds. In addition, we developed a built-in swap feature to enable users to exchange crypto with no KYC. In compliance with local data restrictions, we integrated a South African provider of Know Your Customer (KYC) services to verify the identities of our South African customers.

Results - This is where BloxBytes comes in


The SentiPay platform features Rand Cash (ZARc), a stablecoin developed on the Bitcoin Cash blockchain. Wallet users are encouraged to adopt low-fee cryptocurrencies like XPR, XLM, and BCH to reduce fees and expedite transactions. The SentiPay Wallet supports the following cryptocurrencies: Bitcoin Cash (BCH), Ripple (XPR), Stellar Lumens (XLM), Tether (USDT SLP), and Rand Cash (ZARc).Transactions on SentiPay are free, and consumers earn 1% reward points on each transaction, while merchants are responsible for the transaction fees. Additionally, merchants can offer reward points at no cost, further saving on transaction fees. We ensure that all users accumulate at least $2 (USDT) worth of rewards points before they can use them to cover miner fees and any additional blockchain fees. As a result, the SentiPay Wallet represents the future of payments—cheaper, faster, decentralized, and more convenient than any other system, exclusively developed by BloxBytes.
