I would say design. Because stakes.social is building creator economy. As most of you know, metaverse and nft projects nearly made more attention than defi projects overall in crypto.
Creator economy will probably pull more attention than even nft or metaverse. NFT (mostly pulled digital artists, while creator economy will pull millions of people). I dont think stakes.social look ugly. But it should be more exciting. For example sushi.com. Their design is fresh and exciting.
Creativity needs to be exciting to pull more eyes.
My second suggestion would be an direct swapping between chains. Ethereum to Arbitrum right now for example. With one click upper right corner. Also i can suggest putting the dev bridger to stakes.social also. So someone can directly swap it. Also a live gwei toggler maybe to the website on right upper corner. These should be little details but they are usefull.
I think we definetly need to have a mobile app. Maybe in 2022, i am sure it will take time. But many people do use crypto from their phones.
I think dynamism is important. Most people who are into crypto right now likes dynamism. Easy to use + good looking is the killer shot. Even though i am a long term staker. sTokens are kinda complicated to me.
For example when Perks systems come, we should have an eaiser to use and understand sToken/Perks mechanism.
Also i believe Perks should really easy to understand when someone joins to the stakes.social.
Also one other suggestion i can tell is. I think its hard to find the project to stake for. We should definetly make it easier in long term.
I.E what kind of creator would you like to stake and the preferences on the sides.
Other than that, stakes.social is really cool. Its one of the few apps that i didnt had any problem on using even from phone. Transactions are pretty fast for eth network
