yes crypto wallets can help, although if you want to go deeper this direction, I would say it is important not to use crypto in "encryption" and "digital asset" contexts without further elaboration on which one you are talking about.

reason being that its not clear if you are confusing the contexts or if the reader is. to the delight of cryptography aficionados who may not like the newer asset-based context, it looks like you did it correctly, but people in the crypto-asset space have abstracted the cryptography aspect so well that they would be confused.

the downside is that you will likely be relegating yourself to just the crypto-asset market, which has its own nuances as well as being a general anathema to some of your potential supporters who just want to ramble incoherently against crypto-assets.

fortunately, in crypto-assets your small project with just a few hundred users will probably make orders of magnitude more money than your big project with hundreds of thousands of users.

could you have just used a database? maaaaybe

could you have just made a lot of money while lowering your overhead costs by offloading your entire backend to the wallet and blockchain? definitely
