mythril VS rotki

There are some paid tools and some free ones. A few that come to mind are ConsenSys MythX (based in part on the open-source Mythril), ShiftLeft, Oyente, Octopus… maybe best to just check out ETHSecurity’s list.

When you say "formal verification methods", what kind of techniques are you interested in? While using interactive theorem provers will most likely not become very widespread, there are plenty of tools that use formal techniques to give more correctness guarantees. These tools might give some guarantees, but do not guarantee complete functional correctness. WireGuard (VPN tunnel) is I think a very interesting application where they verified the protocol. There are also some tools in use, e.g. Mythril and CrossHair, that focus on detecting bugs using symbolic execution. There's also INFER from Facebook/Meta which tries to verify memory safety automatically. The following GitHub repo might also interest you, it lists some companies that use formal methods: practical-fm

There is also Rotki which might be more feature rich https://github.com/rotki/rotki

-Rotki: https://rotki.com/ Management

There's also https://rotki.com/ an open source tax software, but it's not so accurate when things get complicated

Check out https://rotki.com/ it's the best free one I've found. Still doesn't compare to a good paid service though

I don't know what company you're talking about? Is it https://rotki.com/? I'm sticking with https://cointracking.info though. I tried a lot of different ones and this one is best for me with multiple wallets, exchanges, derivatives and crazy amount of transactions.
