Hi, I am looking for a smart contract to be created with a unique feature, on ETH chain. I would like a contract creating and deploying, it’s a very straightforward one generally, but I would like the following ability. I want to have a feature where is somebody tries to sell over a certain amount it blocks the transaction and blacklists the wallet from selling only. I would like the ability to control the amount that triggers the block and blacklist dynamically, via a non technical interface. I would like the ability to remove the blacklist status of a wallet via a non technical interface. I would like the ability to add a blacklist status of a wallet manually via a non technical interface. I would like all these features to work after the contract has been renounced. Is this something you could do?

Hi, I am Mark Joohn and I have full experience in developing frontend and backend for 8 years. I understand what you are looking for in terms of a smart contract creation with a unique feature on ETH chain. Specifically, I would like to have the ability to control the amount that triggers the block and blacklist dynamically via a non technical interface. I would like to be able to remove the blacklist status of a wallet via a non technical interface as well. Finally, all features should work after the contract has been renounced so they are accessible to users without the need to contact support afterwards. I believe that my skillset and experience make me the best fit for this project. If you give me the chance to work on this project please let me know if there is anything else you want me to clarify or include in my proposal?

Yes, it is possible to create a smart contract with the features you have described. The contract can be created and deployed on the Ethereum blockchain using Solidity programming language. To implement the feature where a transaction is blocked and the wallet is blacklisted if the sale amount exceeds a certain limit, you can use a modifier in the contract that checks the sale amount and compares it to the limit set by the contract owner. If the sale amount exceeds the limit, the transaction can be blocked and the wallet can be blacklisted. To make the limit dynamic and controllable via a non-technical interface, you can create a function in the contract that allows the contract owner to set the limit. This function can be called using a web interface or a mobile app. To remove the blacklist status of a wallet, you can create another function in the contract that allows the contract owner to remove the wallet from the blacklist. Similarly, to add a wallet to the blacklist, you can create a function that allows the contract owner to add a wallet to the blacklist. All these features can work even after the contract has been renounced, as long as the contract is still deployed on the blockchain and the functions are accessible via a non-technical interface.

As a Blockchain Developer with over 3 years of experience, I can create a contract that will allow you to whitelist or blacklist any wallet when a certain limit is reached. My expertise includes designing, developing, and testing smart contracts, implementing access control for stakeholders through NFT-based whitelisting smart contracts, developing decentralized exchanges, NFT marketplaces, and tokenization of assets. I have also conducted smart contract audits to ensure security and adherence to best practices. Thank you, looking forward to hearing from you to discuss further details.
