Project details

Looking to display data in real-time on your dApp? Guess, you've come to the right place.

Hello there, I'm Hammad, a full-stack blockchain developer and I have been working on web3 applications for a long time. In my journey, I have built subgraphs for multiple different projects including DeFi (Dexes/ CLMs, Liquidity Mining/ Staking), NFT, ICOs Interoperability (bridges), and hence have an in-depth understanding of The Graph protocol.

I can create a subgraph (for any blockchain that The Graph supports) to fetch blockchain data so you can power your front-end interfaces with real-time data.

Catalog's offering:

 • Subgraph for your dApp
 • A document explaining how you can query subgraph to fetch data.

Catalog requirements:

 • Smart contracts to index data from

I can also BUILD A CUSTOM INDEXER or frontend for your dApp, query subgraph or do web3 integration, or write a custom smart contract but these services are NOT covered in this catalog. Please check out my other catalogs or contact me to discuss further.

Please message me before ordering as I'd love to discuss the project with you in advance because the delivery time and cost vary from project to project.
