One of my favorite ideas re: consumer crypto development is from "Product-led protocol development" from @dwr.eth 
https://danromero.org/product-led-protocols.html

TLDR: 
To successfully develop a new protocol, start by building a high-quality initial application that attracts a significant number of engaged users, which will in turn draw developer interest and encourage diverse, thriving client ecosystems.

To take this a step further, how can you extend your protocol with new differentiating features beyond just a smart contract on some execution environment?

This is one of the things /eigenlayer enables.
