I think it's a natural thing, because every transaction we make on a wallet, there will definitely be a record of evidence that we can see, with that we can know whether our transaction was successful or not, and the company from the wallet platform clearly does not have access to our wallet, if you may know what wallet you use?
I am using HubrisOne wallet https://www.hubrisone.com/ they have a lot of security features like fingerprint and facial recognition. I have never lost a single Dollar using this app. I have access to both my BTC and ETH private keys. But I want to know if the company have access to my account or not. check this smart contract to see what I am talking about https://etherscan.io/tx/0x0ac1c7aba4d4a7c9fe09a51133d352af0b67695a03201c443f45a4cd63ca46d0..
