Swapping your coins with another user does not result in an on-chain transaction, so technically it would be invisible to blockchain analysis, provided the withdrawal transactions don't leave any unique fingerprints such as by using unusual nlocktimes or similar (I've not examined the code closely enough to know if this is the case). This could be a good or a bad thing, depending on your specific use case. If you need to hide the fact you are using ChipMixer or a coinjoin, then this wallet could do that. However, this also means that unlike ChipMixer or a coinjoin, the coins you receive are not unlinked from their history. From a blockchain analysis point of view, any coins you receive from this wallet will still have their full history attached, and will simply have gone through a single intermediary address before arriving at your wallet.
