NYCCoin gives citizens and supporters the power to support, improve and program the city that never sleeps.

NewYorkCityCoin is the second CityCoin to launch, built to reward its holders through the Stacks Protocol.

NYCCoin supports NYC while rewarding holders through the Stacks Protocol.

How it works

CityCoins are powered by Stacks, a protocol that enables smart contracts on the Bitcoin network.


The community mines to create CityCoins

Mining CityCoins is performed by forwarding STX tokens into the smart contract in a given Stacks block, and is a one-way process. Miners are rewarded with new CityCoins tokens.


Stackers receive the STX spent to mine the CityCoins

70% of mining rewards are distributed to people who chose to stack their CityCoins (Stackers).


The city's reserved wallet grows

30% of mining rewards are sent (in STX) to a city's custodied reserve wallet.

The city can claim this and convert their STX to USD whenever they want.

NYCCoin is the second CityCoin

Why New York City?

New York City is arguably the cultural, financial, and media capital of the world. Where New York City goes, the world follows.

Over the past decade, New York City has emerged as a leading tech hub, and the city has done an incredible job at cementing itself as an innovation center. The city boasts both a brilliant workforce and the ability to attract talent from every corner of the world. This diverse labor pool, coupled with an abundance of venture capital for builders, provide a foundation for NYC’s future success.

As a testament to New York City’s growing appeal as a burgeoning tech center, Amazon recently announced an office hub with 25,000 employees in the Long Island City neighborhood of Queens. Google and Apple are similarly following suit, and have both announced major operations in New York City. And while these developments are encouraging, it’s important that the technologies that take up an increasingly significant portion of people’s lives remain in the hands of the people. That’s why NYCCoin is designed to enable more active forms of participation for a broader range of city residents and community members.

CityCoins is designed to leverage New York City’s energy, creativity, and entrepreneurial zeal for the city’s benefit. It will be exciting to see what New York City does with NYCCoin.

New York City has not partnered with CityCoins.  

CityCoins like NYCCoin are grassroots initiatives. As communities grow around CityCoins, they can encourage their mayor to claim the reserved city treasury wallet and begin putting its funds to use.

When miners forward STX to earn NYCCoin, 30% will go to the wallet reserved for the city. New York City may decide to claim the wallet’s funds at any time.

The NYCCoin treasury consists of STX, which is sent by miners when they forward the funds to a Stacks smart contract for the right to compete in a mining competition. Whenever STX is forwarded by miners, 30% makes its way into the city treasury.

Whenever the city wishes, they may access their reserved STX inside the wallet. At that point, New York City may use its treasury for whatever it likes, and can stack those STX to earn BTC.

What can NYCCoin holders do with their coins?

Anyone can mine NYCCoin, program NYCCoin via smart contracts, and even earn BTC from the protocol as it gets more usage.  
NYCCoin is a new way for developers to create applications and experiment with innovative use cases. Developers can create apps that use NYCCoin for access control (to digital or physical spaces), trading, lending, smart contract execution, and much more. For example, within two months of launching, a CityCoiner created a “Mint-with-MIA” feature for MiamiCoin. As a result, holders can now create or buy NFTs with their CityCoin.
