Safemoon is an entire ecosystem including their own exchange, not just a token. There is going to be a "cold" wallet coming out soon too. There will be a full tokenomics system for all coins (such as earning coin just for holding bitcoin) although thats going to work on the exchange, and I just assume the wallet will be integrated but I dunno how this will all work and if it will work directly on the wallet.
The wallet is going to be better interface that trustwallet, implement saved contacts and hold other tokens, and will have a reliable price which has been a constant problem with trustwallet.
You will be able to buy tokens directly, but this feature probably wont be on right away.
You should be able to transfer from trustwallet to safemoon wallet for free, but be aware Bitmart is under control of a centralized system so its going to be their own final call. I just transferred mine out and they took all the tokenomics out as a fee ahead of time instead of losing the tokens over the transfer.
There is going to be fun stuff on the wallet such as "savings jar" and setting goals. Potential to buy goods and services.
Hold to cancel feature, such as setting yourself 10 seconds to change your mind if you make a mistake.
Physical Safemoon Card may be implemented into the app, not sure if confirmed but probably.
Built in crypo calculator, probably also useful for tokenomics.
Safemoon is trying to build an empire.
