    We already have a NFT collection published on the Polygon network. The collection is there on Opensea and it's linked to Instagram and Twitter accounts. Right now the collection has a trading volume of ~0.00 eth. What we need is to have a trading volume of at least 1 eth so that marketing the collection would make some sense. We expect the freelancer to have connections with an investor who's ready to adopt the collection. Please bid only if you have a connection with an investor or know how to increase the trading volume. I am ready to provide a link to the project in private chat.

    We are creating a smart contract and are having issues with implementing a small burn tax based strictly off of sells. We are looking for consultation and reviewing the code for it to properly work when using using Ropsten Test The created ERC20 will have tax on sells. We are trying to achieve this by creating a mapping(address => bool) where we set the pool address = true, and then in _transfer function checking if a recipient == to the pool, based on that there is either a normal transfer or a transfer that is taxed. The end goal is that on sales there will be a tax implemented, which will be allocated to a burn wallet. We are open to using other methods is necessary. The priority is for it to work on swaps. Below in the files you will see the current solidity code.

Because IoT objects are not logically connected to blockchain platforms, controller entities (based on RPi) forward all information needed for transaction forgery.
