We need to build an Ethereum Contract with API. The ethereum contract will have the following characteristics. 1. It will allow for tokens in it's wallet to be withdrawn via an API. 2. The tokens to be withdrawn via API should be able to be selected and changed. 3. Transaction fees are to be paid by the contract wallet. 4. Its API Key should be entered at the time of submitting the contact. 5. The API Key can be disabled and changed by contract owner only. 6. The Contract can be paused and started. The contract is to be developed and sent to me so that I can launch it. Please no not ask to be paid by paypal or other method.

Hello, i would like to work in your project, but i need to make some observations to your requirements: 1.- On ethereun gas fees are always paid by the one who makes the transaction, those fees can't by paid from a contract, one workarround could be to make the contract send the expent amount of gas to the caller. 2.- You should NEVER store some kind of key within a contract because, even it's set to private, contract code can be read with anyone, ans stored variables too, also when you send a transaction the infor is broadcasted so anyone can catch the key. made that observations just for security measures. I'm a solidity and dapps developer, if you share with me more information i can give you an idea of what can be done.

Hi, I'm Naveen and have developed quite a few ERC20 tokens on ethereum myself that are live. Developing a contract using solidity on ethereum is a familiar space and could do it anytime. I would like to talk to you about the details of the project so we could get up and done.
