After the merger of Ethereum was completed, there was a short-term surge in NFT sales. For example, the daily growth rate of BAYC reached more than 180%.The data information on the blockchain chain is poor, and the time difference often means a gap in 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.

Why is blockchain data worth analyzing?

As NFT projects are blooming everywhere, the demand for NFT trading is increasing, and Ethereum is gradually becoming a huge financial settlement network.When each NFT transaction needs to pay 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 "ledger data disclosure", which has huge data mining value, such as analyzing the consumption behavior of account addresses and income and expenditure details through these massive data.

How to develop Nansen NFT data analysis tool?

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 parse, filter, process, and then obtain NFT data from massive blockchain data.

Tokenview NFT API self-built multi-chain node

(https://services.tokenview.io/cn/product/nft), eliminating the time-consuming and complicated steps of node construction, data acquisition, data analysis, effective data screening, data verification and other steps for developers, complete structured processing of data, and providing various types of access to NFT datainterface.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 and monitor market dynamics.

NO.2.1 NFT Collection data acquisition

NFT Collection data includes the transaction volume, market value, trend, etc. of each NFT project in the NFT market.Tokenview API provides a full amount of NFT Collection data, including 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 interface supports querying all ERC721 and ERC1155 contracts on Ethereum.

NO.2.2 Smart Money user tracking: NFT transaction information and NFTID

By paying attention to the transaction information of the Collection, it is possible to easily obtain the transaction status and income of each user for different NFT projects. For example, the transaction list of the NFT project BAYC can be obtained through the following API, and then the users who buy and sell BAYC can be analyzed.As well as the cost during the buying and selling process, the user's income can be calculated by analyzing the user's one-in and one-out transactions for the same NFTID.

Get the transaction list of the specified NFT collection

https://services.tokenview.io/nft/{public chain abbreviation lowercase}/blockdata/collection/tokentrans/{collection_address}/{page}/{page_size}?apikey={apikey}

Enter:

Public chain abbreviation: eth

Collection address:

0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d (BAYC contract address)

Page number: 1

Number of page number transactions: 20

Tokenview NFT API competitive advantage?

  1. Self-built multi-chain node cluster

Tokenview is a full-currency blockchain browser that supports BTC, EVM, Layer 2 and other public chains up to 120+. It has the most node clusters in the current public chain nodes and provides rich, diverse and stable API interfaces.Support, with an efficient on-chain data analysis, cleaning and verification mechanism, the team has solid experience in building public chain nodes, has established multiple language versions, multiple public chain clients, and data is distributed on multiple node clusters around the world, effectivelyEnsure the stability of nodes, efficient data synchronization, and diverse data on the chain, which can provide various data required by blockchain applications in different fields.

  1. Data validation

Tokenview NFT API data service has undergone strict iterative data verification to ensure the accuracy of the data, ensure that the historical and newly created NFT contract attributes are correct, and the transaction characteristics are correct. Rigorous basic data is the first step in data analysis, especiallyIt is a huge amount of on-chain data, wrapped in on-chain transactions and smart contract calls. Its complexity and innovation require real-time updates for data analysis and contract understanding. Tokenview NFT API adopts iterative data verification and checks at every level, to provide accurate, credible, and real-time data to data users in the blockchain field.
