Hello ,sir...
How are you?
I have read your description as carefully and I am in interested in your task.
I have rich experiences in Solidaty,Cryptocurrency, Blockchain, Ethereum, SmartContract.
Using smart contract, I have saved data and read it from transaction in node js, Go project.
and then, developed Ethereum ERC-20 smart contract.
In the meantime, I mastered Solidaty and Solidaty developement enviroment such as remix and geth.
To compile and delpoy the solidaty code by using Web3 package, Solc package, is no problem for me.
It is best solution to save data from hacking and destroy.
I can promise about my skill and I will provide good quality result and service.
I hope to get chance to work with you as long term. Best Regards.
