My idea is: Umbrella.
- It refers to the 'everything app' - everything under the same umbrella
- It also creates impression of safety, safe place during the crypto storms
- If I was to design a logo for that it would be in a style of Chaplin(or even Mary Poppins) holding an umbrella as a cool, simple, siluette.
Crella
Your Crypto Umbrella
Unfortunatelly, there is already a caligraphy marketplace on crella.net so I would also consider Crylla (even though that blurs the Umbrella part of the name)
