We need a smart contract (solidity) that allows a user to send 0 eth to the contract and then receive a specified amount of tokens. The user will pay for the gas. The number of tokens the user can receive is currently stored in a csv file in the format "address, qty" The contract owner must be able to deposit a certain amount of the tokens in the contract to cover for the distribution

Hi, all the characteristics that you ask for your project I have already solved in my own projects. I'm currently working on the realization of a blockchain game, in which I'm precisely the developer of solidity. Reading the description of your project raises a question, what kind of token are we talking about? I look forward to working with you. Greetings. Alejo

Hey I can have this done for you today. I have made exchanges, crytpogames, and token contracts so this will be fairly straight forward. The only issue is that the amount each person can withdraw will have to be stored on the blockchain and not in a csv file. How many addresses are in that table?

Hi, I am a blockchain and smart contract developer, creating cryptocurrencies and launching ICOs for about 2 years. I can write exactly the smart contract logic for your requirement. In addition to creating the cryptocurrency, I can also write smart contracts to manage the ICO for you - completely according to your specifications. My previous works include: - LynPay - BaltiCrypto token - CargoCoin - NoxusCoin - Cryptocricket You should hire me because I am always available, provide top-notch work quality and will not rest until you are satisfied with the product delivered. Hoping to take this forward.
