Web3 wallet trackers provide comprehensive wallet analysis and tracking tools for cryptocurrency asset investors by integrating blockchain data APIs. Users can use wallet trackers to track the total assets and transaction history of specific wallet addresses, analyze historical transactions to discover trading trends, set asset price alerts, generate wallet reports, and mark important wallet addresses. Wallet trackers support cross-chain asset tracking and have wide data coverage. They have become an essential tool in the cryptocurrency market.When developing a Web3 wallet tracker, various types of data need to be processed, and there may be challenges in integrating and processing this data, including but not limited to the following basic data:1/ Blockchain transaction data: It is necessary to obtain and parse transaction data on the blockchain. This may involve handling transaction formats from different blockchain networks and addressing issues such as transaction confirmations and confirmations.2/ Blockchain state data: In addition to transaction data, it may be necessary to obtain other state data on the blockchain, such as the state of smart contracts or the current state of on-chain assets.3/ User wallet data: It is necessary to obtain the asset balance and transaction history of user wallet addresses. This involves interacting with users’ wallets and ensuring the security and privacy protection of the data.4/ Real-time price data: To display the real-time value of assets, it is necessary to obtain price data for cryptocurrencies. This may involve integrating with multiple exchanges or price data providers and handling price data from different sources.5/ Data security: As sensitive user data, such as private keys or transaction history, is involved, it is necessary to ensure the data security of the tracker, such as encrypted data transmission and secure storage.NFTs are a special form of cryptocurrency asset with uniqueness and non-fungibility on the blockchain. They have wide applications in digital art, gaming, and collectibles, and the rapid growth of the NFT market has been a significant trend in the digital asset field in recent years.In this context, NFTScan NFT API provides powerful tools for developers to easily and quickly access and analyze comprehensive data on the NFT market.
