This is a company which will NEVER drug test its employees. There will never be disciplinary action ta...

    Hello, I want a website similar to Amazon. But that the payment is made through cryptocurrencies and other functions that I will comment on privately. I want the crypto to go to the website wallet first and then when the buyer accepts the service as received, the money will automatically go to the seller's wallet. There are no ethereum contracts as we don't want to be saddled with their huge gas fees. Only experienced people, no wordpress, don't waste my time. If the project is carried out well, there is a high possibility that they will be hired again for a much higher salary for a long period of time. Please put this word at the beginning of your message to ensure you have completely read the project description: "Wallipal"
