We also think we offer something that might be of interest to users looking for alternatives to coinjoin:

 - blinded submarine swaps
 - reverse submarine swaps - though both of these are with counterparty risk
 - internal transfers,
 - regular blinded on-chain deposit/withdraws, against (currently) 0% fees - this might change at some point in the future
 - Economies of Scale

The privacy implications of our product are enormous and pretty revolutionary if used correctly: your withdrawn funds will be consisting of any deposit made by other users, including your own.

Given a large enough userbase and correct usage of our product (for example: timing & non-unique withdrawal amounts) we believe that a very high degree of on-chain privacy can be achieved.

Though of course there is (as of right now) a significant catch: we are a centralized entity. While all of our communications are provably-honest and privacy against us is retained using blinded schnorr signatures, we can at any point in time break that promise.

We think our product stacks up very well against currently existing mixers
 
 + free internal transfers - allows you to transfer btc to a friend off-chain / with privacy
 + complete lightning integration - make blinded lightning transfers
 + provably-honest communications
 + blinded-sig scheme - provable privacy against the mixer
 + cheaper - only pay network fees as of now
 + can be used as a day-to-day wallet - added privacy + no additional transactions required in comparison to traditional mixers
 + insert withdrawal as a batch transaction - only pay for the output space ~31 vb
 + open-source software
 - incorrect use or lack of use by other users can make it easy for blockchain heuristics.

compared to CoinJoins:

 + more flexible - withdraw any amount at any point
 +- may or may not offer better on-chain privacy. This is something that largely depends on how many users we have and how you use us*.
 - centralized - requires custody over your funds
 + cheaper ?
 + can be used as a day-to-day wallet - added privacy + no additional transactions required in comparison to traditional coinjoins
