Announcing the FOAM Map Developer Grant Program


Foamspace is committed to building open and decentralized alternatives to current mapping and location positioning solutions. As part of that effort, a vibrant developer community that builds their own solutions using FOAM’s open-source standards and protocols is vital.

Today we’re excited to announce the FOAM Grants Program for projects building on the FOAM API. Accepted proposals will receive a grant of FOAM tokens between 50,000 and 500,000 per project for use directly in connection with the FOAM platform. The project’s proposed use of tokens should be directly tied to adding points of interest to the open registry of the FOAM Map and or tools build around the FOAM Map API.

“We’re now seeing a lot more community-led initiatives and tools,” King said. “It’s open source and the stakeholders are going to be the ones driving it going forward.”

For example, supply chain management expert Coleman Moore recently organized and led the first Foam Community Proposal call. Moore told CoinDesk the call had roughly 20 participants and he is already planning a followup call. He said that in his profession companies rely on proprietary services or volunteer radio beckons for data. So he believes an open source tool with economic incentives to keep the data clean, via the TCR, offers an attractive alternative.

“On top of [incentives], Foam uses a blockchain, which really adds value because if you can imagine a world where everything is connected to the internet you don’t want that to be controlled by a centralized network server,” Moore said.

Highlighting Moore’s point about incentives, Microsoft engineer Cody Born collected Microsoft Azure tools to support the Foam scavenger hunt, which rewarded people for verifying location data with a custom non-fungible token (NFT) of the buildings they added to the map. Born himself won several NFTs through one of the online scavenger hunts.

“I liked that scavenger hunt so much because it combined a lot of my interests – which are blockchain, TCRs, incentivization and collecting things,” Born told CoinDesk. “That motivated me to get more engaged in the Foam community and participate in the various forums.”

Examples of potential projects:

  • Map Games,
  • Tooling for FOAM Map Community
  • Code contributions for FOAM Map smart contracts, Bridges to existing protocols,
  • New map Interfaces and Designs using the FOAM Registry.

Of course, the developer Grants Program is not limited to the above. We want to hear your ideas, ranging far and wide. Please note that a separate grant related to FOAM Location will be announced as first testnets are deployed.


  • Grant recipients must use FOAM tokens in connection with the FOAM protocol.

  • Project should be open source and designed to use the FOAM API.

  • Project should be intended to benefit the FOAM protocol as a whole (Foamspace will not take any equity or commercial interest in your project)

  • We have an office space at the New Lab in Brooklyn, New York that may be used during development.

  • Project should provide documentation and share process with the FOAM community.

  • Projects with existing codebase are a plus.

Grants will be considered on a rolling basis. All projects approved by Foamspace may be made public in both name and application.

What should a proposal describe?

The project’s goal, scope and how it uses the existing FOAM API.
A clear description of intended outcomes based on a 1-3 month timeline. Team member’s relevant coding, research experiences and Github repo The amount of FOAM requested for intended use
How the project will share progress with the community

Submit your proposal to

We will open our office at New Lab, NYC during ETH New York (May 17 - 19, New Lab) for developers interested in FOAM. This also is great opportunity to meet our developer team and discuss your grant proposals in person. Sign up here:

A grant prompt we would love to see:

Visualizing the FOAM Map


The FOAM Map [web application](http://(https// a visualization tool for our token curated registry(TCR), which is a set of smart contracts used to curate points of interest(POIs),as well as our Signal registry, which is an NFT backed staking contract. There are several views in this web application, but they largely fall into two categories. The first set of views is useful for things like adding POIs or Signals and participating in challenges. The second set consists of data visualization tools that include things like the POI and Signal explorer, the Signal heat map layer, and the POI search capabilities. Our primary visualization tool for this is a Javascript library called makes visualizing geospatial data on top of Mapbox as simple as changing some layer configuration. The landing page has several compelling examples.


We’re interested in what you kinds of map visualizations you can come up with powered by the FOAM MAP API. We encourage you to use find tutorials and examples on their github) but you’re of course welcome to use whatever tools you want. Your task would be to explore that data and draw some conclusions from the visualizations. The visualizations

should also be compelling, which is why we recommend something like Some sample questions might be:

  1. How is FOAM Token staked in POIs distributed geographically?
  2. Do cartographers typically place POIs in a neighborhood, or are they posting globall?
  3. Does voting and challenging occur within user groups or is it global? I.e. do people tend to participate in challenges in a neighborhood or globally?


the ratio of views to replies / time ought to illuminate that something’s a miss


Hi Ryan,

This seems very interesting! I got introduced to FOAM project last weekend and have been deep diving on ways to contribute. This project looks a good entry point as I have previous background in data visualization research (, d3.js, openstreetmap). Will be deep diving to come up with a proposal for the same.


Great to hear! Looking forward to your proposal and get in touch if you have any additional questions.


Hi @arthur, @Ryan_foam,

Have sent a proposal your way on Would love to get your feedback, critiques on it.


@Prastut Great! Thanks for sending, received. Will follow up shortly, the first batch of applications have come in, all very innovative proposals.


Awesome!! Tools for visualizing map interaction could help design secondary applications… like games that incentivize users to place points.


@Ryan_foam Would you have awareness by when you would be able to arrive at a decision around the updated proposal that I had sent across?


Thanks @Prastut for following up and your patience, we will get back to you on your proposal this week.
