Meet Honeycomb – Connecting Smart Contracts to High Quality External Data; An API Marketplace

Asia Blockchain Review
September 28, 2020

EMURGO is excited to welcome Honeycomb, one of our latest batch members of the dLab/EMURGO startup accelerator in 2020.

What is Honeycomb?

Honeycomb is an API marketplace that links blockchain-based smart contracts to the datasets they need to create meaningful, real-world applications.

Honeycomb works by connecting premium API data providers to decentralized oracles. This makes the API available for smart contracts without a centralized point of failure, which is one of the unique properties made possible by utilizing blockchain technology.

On the Honeycomb API marketplace, smart contract developers can browse and access a wide library of APIs from various different categories. Through an easy-to-use interface, connecting smart contracts to the data that developers need is made extremely simple.

Why Should Cardano Developers Care About Honeycomb?

Distributed applications (dApps) that use smart contracts rely on datasets from around the world. APIs deliver this data. With the upcoming release of Goguen, (the phase of Cardano’s development which will launch smart contract capabilities) APIs are extremely important.

Data types from Honeycomb-listed APIs include: market data for both traditional assets and crypto, forex rates, weather data, flight data, city and population data, sports scores and much more.

These are necessary for Cardano dApp developers to create distributed applications in areas such as DeFi, insurance, trade finance, sports betting, or any data-rich dApp that requires data of events that happen outside of the blockchain that host the smart contracts.

Honeycomb estimates that over 80% of all feasible smart contract use cases can be covered by the data they help provide. Honeycomb is aiming to support the Cardano blockchain with the availability of APIs after the launch of smart contracts.

dLab/EMURGO Offers Technical & Business Mentoring to Increase Value

dLab/EMURGO’s guidance has been instrumental to helping the Honeycomb team grow and develop. According to Founder & CEO Heikki Vänttinen,

dLab and EMURGO have a wealth of knowledge on the challenges we face in making these novel smart contract use-cases possible, so they’ve been able to help us a lot along the way, both through asking the right technical questions and giving solid advice from the perspective of experienced builders in this space.

We definitely feel like we took home not only a lot of knowledge, but also some valuable contacts that can help us realize the potential of what we’re building with Honeycomb.
