Nice lettermark. I think the chainlink as part of the W is a clever idea, but it just doesn't play out well. Maybe try without the link? Or modifying it? The colors and wordmark are pretty straight forward. I am leaning towards all uppercase, like you have, bold font.
Good job on the lettermark. The wordmark now needs something to distinguish itself. It's straight forward and meets basic requirements. Feel free to get creative with it. Something special.
