Can Tangem block access to the wallet?

Tangem doesn’t have its own servers that connect to blockchains. It is the app on your phone which communicates directly with the blockchain. This means that we cannot with operations in any way. Tangem's philosophy is to provide users with a technological solution for interacting with crypto assets and nothing more. The wallet protocol looks like this: card <-> application <-> blockchain.

Besides, we don't conduct registration or verification of users, so we don't know their geolocation, citizenship, etc. This means we can't identify a particular user to block their wallet access (even if that were possible). All we can hypothetically find out is your IP address, which can still be changed with a VPN if necessary.

Plus, our app is open source and published on GitHub. With some skills, anyone can study it, make sure it's secure and compile the app.
