Covalent at Scaling Ethereum: Winners Announced

Covalent is pleased to have been one of the sponsors of Scaling Ethereum Hackathon 2021 by ETHGlobal, offering a total of $3,000 (USDT) in prizes to developers integrating Covalent API in their projects!

The Scaling Ethereum hackathon is dedicated to ideas committed to upgrading the foundation of Ethereum and ETH2 with the overall goal of the event being to encourage developers to build with an entire ecosystem behind them. Covalent was honoured to be a part of this event. Hackathons such as Scaling Ethereum are ideal for developers to use Covalent's no-code solution to build and scale projects quickly. This is why over 100 projects including CoinGecko, 0x, and Balancer are powered by the Covalent API.

We received numerous submissions that showcased a wide range of creativity. From wash trading monitoring DApps with full graph visualizations to dashboards with on-chain analytics of how tokens flow through Layer 2 and sidechain from Ethereum. We are grateful to all the participants, fellow sponsors, and judges who made Scaling Ethereum Hackathon successful, and a special thanks to ETHGlobal for continuing to support developers who are building a fair future.

And without further ado, here are the top 3 Scaling Ethereum projects using the Covalent API, each winning $1000 USDT:

Covalent Scaling Ethereum Winners

CoinPort by JC AWE, Hunter Chen, Robert Weisz, Vadiraj Kulkarni, Spencer Renenger


Using easy-to-read visualizations from data sourced from the Covalent API, CoinPort offers insightful and detailed data on the history of your DeFi portfolio, conveniently all in one place.

The Covalent API is convenient for getting token info with price in an address.

Eth Hole by Fred Lin


Eth Hole provides robust on-chain analytics of how tokens flow through layer 2's and sidechain's from Ethereum.

On using the Covalent API, Fred Lin had the following to say:

We used the Covalent API to grab user token balances as JSON, we may also use it to get the individual pool balances. The token balances API was really easy to use and parse. it also contained data that we aren't using at the time but can be quite useful in the future, particularly the token icon images.

PixelProperty by Carson Roscoe


The community-driven, evolving digital canvas running on sidechain's with Connext bridges linking them. PixelProperty uses Covalent API to gather and handle all the data across multiple chains. Thus, forming an aggregated canvas.

It was very straight forward and easy to plug in with Axios.

Congratulations again to all the hackers and winners!
