A community currency
to uplift Harlem

An economic platform to empower Harlem’s residents to earn crypto and inspire positive community actions.

Update on Harlem Coin - click here

Last year (2022) we introduced Harlem Coin, a community currency aimed at uplifting and empowering Harlem's residents. Since then, it has become clear that more development is needed for Harlem Coin to truly thrive.

We believe deeply in the promise of localized economies and impact currencies. However, the Harlem Coin ecosystem requires further planning and maturation before launch.

As part of a larger phased rollout, we will be relaunching Harlem Coin as part of the Holon City platform in the future. Holon City is our vision for interconnected local economies that put community first.

Though Harlem Coin is on hold for now, we remain committed to our mission of economic empowerment and community building in Harlem. We appreciate your patience and understanding as we work to develop the strongest possible foundation for Harlem Coin's success.

Please visit to learn more about our work and vision for community-driven economic development. We welcome your involvement and feedback as we build towards the relaunch.

Thank you for your interest and support. We look forward to sharing more soon!

What is a Social Token?

A social token is a cryptocurrency based on creating value and empowerment. Web3 is decentralized, co-creative, and based on ownership, where tokens align participants toward a common goal. Unlike non-fungible tokens (NFTs), these are identical, like a dollar. The utility is what’s important. 

What is the Harlem Coin’s environmental impact?

Harlem Coin is built on Celo’s blockchain – the world’s first to be carbon negative. Celo’s Proof-of-Stake (POS) consensus algorithm naturally requires a tiny fraction of the energy usage of Proof-of-Work (POW) algorithms as used by Bitcoin and Ethereum. It has achieved 8x carbon negativity by contributing daily offsets in association with Wren.

Is Harlem Coin a cryptocurrency?

Harlem Coin is a social token on the carbon-negative Celo blockchain. It does not qualify as a traditional currency but has its value in what it can achieve for the members of the movement.
