How to develop a Nansen statistics platform using Tokenview NFT API

5 min readSep 21, 2022

After the completion of the Ethereum merger, there was a short-term surge in NFT sales, such as BAYC’s daily increase of more than 180%. The information gap of the data on the blockchain, and the time difference often means the gap of assets. If such gaps need to be reduced, more specialized data analysis tools are required. Nansen is a well-known NFT data analysis tool in the blockchain field, including NFT Collections, Smart Money, etc., and is sought after by many NFT Fans.

1. Why is blockchain data worth analyzing?

With the proliferation of NFT projects, the demand for NFT buying and selling has increased, and Ethereum is gradually becoming a huge financial settlement network. When each NFT transaction requires an average settlement cost of more than ten dollars, the business itself must have corresponding investment or use value. On the other hand, one of the characteristics of the blockchain network is the “opening of ledger data”, which has huge data mining value, such as analyzing the consumption behavior of account addresses, income and expenditure details, etc. through these massive data.

2. How to develop a Nansen?

Data analysis tools are very important. How to develop an analysis tool similar to Nansen? The first step in data analysis is to obtain data, and it is an important step to analyze, filter, process, and then obtain NFT data from massive blockchain data.

Tokenview NFT API (https://services.tokenview.io/en/product/nft#utm_source=M&utm_medium=D&utm_campaign=medium) self-built multi-chain nodes, eliminating the time-consuming, labor-intensive and complex node construction, data acquisition, data analysis, effective data screening, data calibration and various steps such as verification, complete structured processing of the data, and provide various interfaces to access NFT data. Users can obtain data on demand, including on-chain transaction data, NFT Metadata, NFT market data, NFT ranking statistics, etc., and can quickly create NFT applications and projects to monitor market trends.

A. NFT Collection data acquisition

The NFT Collection data contains the transaction volume, market capitalization, trends, etc. of each NFT project in the NFT market. Tokenview API provides a full amount of NFT Collection data, including the collection name, creation time, 24-hour transaction volume and other basic data information. It can be quickly obtained directly through the Tokenview API.

The Tokenview API supports querying all ERC721 and ERC1155 contracts on Ethereum.

B. Smart Money Tracking: NFT transaction information and NFT ID

By paying attention to the collection transaction information, you can easily obtain the trading status and income of each user for different NFT projects. For example, you can obtain the transaction list of the BAYC NFT project through the following API, and then analyze the users who buy and sell BAYC, as well as the buying and selling process. The user’s income can be calculated by analyzing the user’s one-in-one-out transaction for the same NFTID.

3. Competitive advantages of Tokenview NFT API

A. Self-built multi-chain node cluster

Tokenview is a multi-crypto blockchain explorer that supports more than 120 public chains such as BTC, EVM, Layer 2, etc. It has built a node cluster with the largest number of public chain nodes, and provides rich, diverse and stable API. Efficient on-chain data analysis, cleaning and verification mechanism. The team has solid experience in public chain node construction, and has established multiple language versions and multiple public chain clients. Data is distributed on multiple node clusters around the world, effectively ensuring node stability the data is efficiently synchronized, and the data on the chain is diverse, which can provide various data required for blockchain applications in different fields.

B. Data Verification

The Tokenview NFT API data service has undergone strict iterative data verification to ensure the accuracy of data, the correct attributes of history and new NFT contracts, and correct transaction characteristics. Rigorous basic data is the first step in data analysis, especially for huge data. On-chain data is wrapped in on-chain transactions and smart contract calls. Its complexity and innovation require real-time updating of data parsing and contract understanding. The Tokenview NFT API adopts iterative data verification, layer-by-layer checks, and Data consumers in the blockchain field provide accurate, trusted, real-time data.

4. Summary

With the increasing importance of the encrypted economy in the world, on-chain data analysis will also become more and more useful. If there is a professional data analysis tool such as Nansen, it is bound to be sought after by blockchain users. Tokenview NFT API is a good helper for the development of blockchain data analysis platform. It not only supports 120+ public chain node clusters, but also provides data services that have undergone strict iterative data verification, so that data can be tracked in real time, rigorously and accurately. Using the Tokenview NFT API, you can easily develop a data analysis and statistics platform similar to Nansen.
