12 Accelerator Projects Building CityCoins utility

share this

Last week the Stacks Accelerator announced its second cohort of projects, including twelve focused on adding new utility to the CityCoins protocol.

The breadth of applications among these twelve projects—gaming, health, DeFi, conservation, housing, and more—shows just how powerful and flexible the CityCoins protocol is.

Read on to learn more about these projects, their teams, and how you can support and participate.


Zeer, led by co-founders Adam Jones, Eli Feight, and Tanmoy Khanra, supports social justice with blockchain technology. Zeer achieves this by providing a next-gen 911 or “panic button” app integrating a blockchain chain-of-custody method to record and preserve crime scene evidence.

In an emergency, simply open Zeer manually or speak your secret safeword into your device, and Zeer automatically calls 911 and begins live streaming video and location data to your emergency contacts and first responders. All evidence recorded by Zeer is backed up in the cloud with distributed ledger technology.

With help from the Stacks Incubator, Zeer is incorporating CityCoins to reward prosocial behavior via gamification.

The service is available now in beta. Learn more about Zeer here.


Stacks Degens

Stacks Degens, led by Bowtied Sir Jonathan, brings GameFi to CityCoins. Built on Stacks and secured by CityCoins, Stacks Degens builds the foundation of P2E games on Stacks through their racing game, Degen Racer. Players race their Degen NFTs against other token holders to win badges, crypto (like STX or CityCoins), and even custom NFTs.

"We want players to earn through playing, but also take their winnings, stack it, and earn yield that way when they're not competing." Read a recap of the first CityCoins Builders showcase for more on Stacks Degens.

Stacks Degens and Degen Racer are ready to play now. To mint a racer, start racing, and earn rewards, go here.


Efani, led by CEO Haseeb Awan — co-founder of Bitaccess (the world's leading vendor of Bitcoin ATMs) and Y Combinator alum—creates a next generation Wireless Network for mobile devices with a special focus on security. With Efani anyone can host a 5G cell tower and spin up their own carrier on Efani’s CipherZero network.

Why might someone want to run their own cell tower? Cyber attacks against personal phones are common and rising, and because of the difficulty, expense, and time required to get recourse, about 95% go unreported. Efani replaces your monthly cell service bill with a plan centred on increased security for your mobile devices. It does this by encrypting your personal data, protecting against SIM swap attacks via an encrypted SIM card, and including $5M in insurance coverage.

Efani is available now. Learn more here.

This allows shoppers to earn free perks while also helping merchants retain engaged customers.

Theopetra DAO

Theopatra is using web3 to make home ownership more affordable. It provides a next-generation real estate ownership and management model via its native token, $THEO. By letting portfolio managers and landlords stake equity from properties, it facilitates effective rent control for tenants to help keep housing affordable.

“If trends continue, we will be past 2008 debt-to-income ratios within 5-7 years in California,” explains founder Mel Anic. “To me, we need to solve this immediately.”

Inspired by the CityCoins model, Theopetra’s uses its yield to ensure that rent only raises by 1%, as opposed to the double-digit averages some cities see. This includes Miami, which recently used $5 million USD from its CityCoins wallet to combat rent increases for vulnerable populations.

Theopatra launches in June 2022. Learn more here.

E8 Internet

E8 Internet, led by CEO Kevin Grace, is building a next generation Internet service and redesigning the ISP experience via blockchain. E8 empowers Bitcoin-native internet of things (IoT) protocols as well as IoT micropayments for the Bitcoin money stack. Community members can use their CityCoins wallet to build hotspots and enable secure, fast, and reliable internet connectivity for their neighbors.

E8 Internet is available now. Visit their site to learn more.
