Zcash KaiOS Wallet

Proposal Name: Zcash KaiOS Wallet

Applicant Background: KaiFoundry is the leading technology solution providing company working in the world of KaiOS Creating all types of Gaming, News, Social Media and Blockchain apps for the people using the KaiOS platform. We already have 5 applications deployed on KaiOS with a cumulative user base of more than half a million users.

We are looking to create the first KaiOS wallet for Zcash ecosystem. KaiOS brings the best of smartphones to affordable devices. Audience accessing this OS are first-time internet users from Asia, Africa, and South America.

KaiOS is the third largest OS in the world with 160 million plus running devices. A wide audience of newly onboarded Internet users don’t have access to Web 3.0, due to unavailability of dApps, building on the KaiOS Platform. We need to provide the access to Zcash ecosystem to the KaiOS users who are from countries like Africa, Asia and South America.

Problem Statement: Currently there is no KaiOS wallet available for Zcash. KaiOS is the world’s third largest OS with active 160 million plus devices particularly from countries like Africa, Asia and South America. There’s a great opportunity to on-board these users into the Zcash ecosystem and empower them with Zcash payment solutions.

Proposal: We will be creating a mobile wallet for low specs phone working on KaiOS that has 160M+ users globally where people can create and import their wallet where they can do transactions and share address either via whatsapp and other social media platforms or through scanning QR codes of the addresses that makes transactions easier. We will make a comprehensive and easy to use UI to ease the onboarding process for the KaiOS users into the Zcash ecosystem.

Welcome to the forum @KaiFoundry :wave:

As KaiOS devices are low specs, do you think it’s possibe to implement shielded mobile wallets for it? And from what I know, KaiOS users are usually first-time internet users with limited internet connection. Do you have a proposed solution for this? Zcash shielded transactions require users to have good internet connection. Or, are you planning to have a Zcash wallet with only transparent support?

Anyway, good luck with the proposal!


Thank you @aquietinvestor

Hello @tokidoki , I hope you are doing well.

Almost all of the KaiOS phones could run YouTube streaming smoothly. In fact the new KaiOS devices even support 4G network. Internet connectivity is not an issue with most of the KaiOS users. This is something that we have seen with our past applications as well already live on KaiOS appstore.

Our current approach would be create wallet with both transparent and shielded addresses support.

Thankyou for your questions, I appreciate you taking out time to read through our proposal.

Hi team, the number of KaiOS users are in excess of 170 million devices. There is strong demand for crypto apps which can be demonstrated by our application hodlinfo which alone has more than 200K users on KaiOS. Hodlinfo shows the prices of different crypto.

Now building further for KaiOS users we wanted to offer Zcash wallet to them so that they can experience the privacy features of Zcash. We are fully capable and experienced in working in KaiOS ecosystem and will deliver a high quality Zcash wallet.

Zcash has set aside 1.5 million USD budget for wallet this year and we are just requesting $40,000 which can be easily attributed a fair ask. We request foundation to look at the growth coming to Bitcoin from countries in Africa, South America and South Asia. These nations have particularly unstable national currencies and citizens have a tendency to buy crypto. We can easily tap into these nations with the KaiOS. This wallet will surely contribute to the growth and reach of Zcash and KaiFoundry is well positioned to deliver the wallet.
