Hello, I work with Adobe Illustrator, and can create vector logo for you. I can provide .eps, .pdf, .ai, .svg, .png, .jpg source files. Your project is really interesting, I have never been working with blockchain companies, and I think that it can be useful experience for me. We can discuss creating several test conceptions for logo before hiring, but it would be great to know more details of your project. Please message me if you are interested. We can discuss any details of project in chat. Thank you for your consideration, with best regards, Maria!
