Covalent API - builders program application

Shiden indexing grant


Developers who use the Covalent API to access all Class A endpoints (as defined in existing Covalent documentation) to pull all on-chain data to a level that is done similarly to other blockchains that Covalent has engaged with to date. Noting that items 6,7,8 are optional based on the Astar ecosystem, and will require smart contracts to be live on the platform but are not mandatory. These are ways which Covalent proposes to provide value on an ongoing basis.

About Covalent:

Our vision is to empower the pioneers of tomorrow by providing the richest and most robust data infrastructure for the entire blockchain ecosystem.

This is done by providing a single API to query any piece of data across 12+ blockchains, which is used by 10,000+ developers, and 300+ live projects including Coingecko, Zerion, Sovryn, 0X, NFTX, and hundreds of others.

How Covalent works:

Covalent is an ELT data pipeline that ingests all on-chain data which comes from blockchains. This can save developers hundreds of hours of development per year where they can focus on shipping products opposed to building or maintaining their own data infrastructure.


“Blockchains make data transparent, but by default that data is raw making it very difficult to analyze, interpret, and understand. Covalent is helping us create meaningful KPIs around Moonbeam platform usage. We are using these KPIs to understand the growth of our ecosystem and to focus our energy into the highest impact areas. Covalent’s comprehensive data set means we can iterate on and refine these KPIs as we learn more, without having to rebuild from scratch.” - Derek Yoo, CEO of Purestake / Moonbeam Network

@Ambassadors Feel free to post comments and questions here!


I don’t agree with 50% deposit/advance payment before any work is being done. 10% is more than good. The rest can be paid progressively every month depending on how much work is being done.

I haven’t actually used it, but as far as I read the explanation, I think Covalent is a good product. Therefore, I basically support this proposal.
However, as moonme points out, I think it’s a little problem to say that the deposit is 50%.

I support this initiative

I made this post, and I do agree. We would be happy to accept compensation once 100% of the work on the Covalent side has been completed.


Other than the Chinese lucky number aspect is there a tradition or reasons for the proposal costing $88,888.88?

It looks interesting for us and all good to me.

No significance whatsoever. It’s my lucky number, and it covers our hard annual costs.
