Question

Q6. Find the wallet that collects Opensea fees. Make a dashboard showing how much Opensea has earned through Polygon transactions.

Part1

Methodology

A transaction fee is paid to the miner for processing the transaction. To find the address to which these fees are paid, we need to find the address that processes opensea transactions. For this purpose, we checked the transfer microtransaction for several nfts from several different collections. Please note that in this selection, we chose nfts that have at least a history of buying and selling. The contract address shared by all of them was equal to 0xf715beb51ec8f63317d66f491e37e7bb048fcc2d. Therefore, orchestrates all the trading activity on Polygon's OpenSea is 0xf715beb51ec8f63317d66f491e37e7bb048fcc2d.

Using the transactions, we are also able to find out that the coordinator address 0xf715beb51ec8f63317d66f491e37e7bb048fcc2d is also responsible for sending the collected fees and royalties to their intended destinations. Now, if every sale has a fee, it is logical to assume that the address that received the most deposits (by transaction count) from the coordinator address is OpenSea's fee collector address. With this in mind, the deposit counts from the coordinator address to each address for successful sales are found out. As expected, the result shows only one address that stands out from the rest, which is 0x5b3256965e7c3cf26e11fcaf296dfc8807c01073.

conclusion

The wallet that collects Opensea fees is 0x5b3256965e7c3cf26e11fcaf296dfc8807c01073

Part2

Now we want to check how much Opensea has earned through Polygon.

First, we earn daily through each of DAI، REVV, WETH and USDC tokens How much fee was charged? First, we calculate through each of DAI، REVV, WETH and USDC tokens how much fee is earned daily.

The total amount of fees received so far through these four tokens is approximately 339 thousand dollars.

Now, if we put together the graph of the daily fee earned from all 4 tokens, we can see that the highest fee is earned from WETH.

The chart below shows the total amount of daily fees received in dollars from all four tokens.
