Polygon blockchain data analysis

This project to understand how to correcly pull data from blockchain to get some outputs.

OpenSea NFT transactions related to some user

We pulled data from Polygon blockchain, so there were 5 transactions in total:

1. NFT transfer
2. Buyer -> Seller (payment)
3. Seller -> Fees acc
4. Fees acc -> OpenSea fee
5. Fees acc -> Royalty to NFT creator

As a result we've got next table structure:

transaction_hash              string      #0xabcdef92893
block_time                    timestamp   #2022-01-01 01:00:00

buyer                         string      #0xd0d0d0
seller                        string      #0xe0e0e0
total_sell                    decimal     #0.5

block_number                  int         #4830198
