This is part one of a multi-part evolving project. This is webapp solution will allow users to extract the blockchain data of the users' wallets. Data will be saved to a SQL server. The webapp will also periodically capture incremental data of the wallets. The webapp will then allow the user to view their wallet ledgers and token asset summary. To keep this project small and on budget, we will work only with the Ethereum blockchain. If you add BTC, TRX, EOS, NEO, LTC, we will also provide a bonus (negotiable). This project will be created as a PWA using VUEJS, VUEX, VUETIFY, etc. This will be completed in 4 weeks.

basically if you need to extract data from blockchain based on erc20 compliant tokens created by you, we need to create a dapp to interact with the smart contract. what you call as web app, we can create it to extract data from blockchain and save it to SQL. I have already created many smart contracts and Dapps earlier. pls msg me , I will give you the smart contract address to check. thanks
