Discoverable rabbit holes on Zapper v2


Cost savings with Alchemy


Requests per minute to Alchemy's Infrastructure

We were already using Alchemy for Polygon and Arbitrum support. We tested Alchemy on Ethereum and never looked back. It resulted in higher performance and significant cost savings for us.

Pioneering Blockchain Data Discovery

Blockchain data is growing exponentially. Most of the data is disorganized, siloed, and inaccessible – making it hard to understand how the web3 ecosystem fits together. Unlike web2, where data is centralized, web3 data is owned by users. But mapping out how web3 transactions are related to each other, each with a unique user and action, is almost impossible. 

In service of their mission to make web3 accessible by translating on-chain information into rabbit holes that anyone can explore, Zapper wants to fix the web3 data discovery problem.

With the first web3 value graph, a map between NFTs, DeFi, apps, DAOs, wallets, and coins, Zapper has created radical interconnectedness across all aspects of web3.

Re-Building from Scratch With Alchemy

Building a first-of-its-kind web3 search engine requires reliable and scalable infrastructure. Previously, Zapper's portfolio display relied on a combination of different blockchain infrastructure companies, and they leveraged Alchemy for Arbitrum and Polygon support.

After conducting a variety of stress tests on different infrastructure providers, the results were clear: Alchemy’s service was the most performant, which translated into significant cost savings. Based on these results, Zapper transitioned to Alchemy for Ethereum and Optimism support, too. 

We ran a variety of benchmarking tests for different blockchain infrastructures. The results were clear: Alchemy was more reliable and stable across every type of request. This translated to significant cost savings for us.

Fast On-Chain Indexing

Zapper’s NFT indexer relies on on-chain data, ingested and stored in an easy-to-use, accessible database. Through this indexing, Zapper users are able to discover trending collections and relevant transactions as soon as they happen.

Maintaining Data Accuracy

Building a product designed to provide uniquely actionable insights requires that the ingested data is 100% accurate and reliable

As Zapper moves into the search engine space, they have started to utilize Alchemy’s Trace API, which provides an in-depth look at every transaction on the blockchain.

No other provider in web3 offers as many trace endpoints, which give developers the detailed on-chain activity insights necessary to interpret blockchain data accurately. Alchemy’s Trace API provides this in-depth data, thus making the information surfaced on Zapper more accurate.  

Initially we were not using traces and figured we were missing about 5-10% of collections. With the data accuracy of Alchemy’s Trace API, we receive the correct data for every call, 100% of the time.
