My mist-wallet is used for purely for dapp development. To fuel my future ambitions, I went to an online exchange and bought some ether coins and used a mobile-only wallet for these real ether. When trying to research how a mobile wallet differs from Mist-wallet, it seems mobile wallet is a contract and my mobile wallet company participates on my behalf in EVM. If this is the case, how can I trust my mobile wallet company? Can my mobile wallet company transfer all the currency I got into their own and blame it on hackers? TIA
The theory is that a wallet client should be open-source and the community will vet the code to make sure there are no trick or devilry within. Unfortunately, as The DAO recently exposed, mistakes are often left noticed and exploited by bad attackers.
Unless you have coded the client yourself, you can really never be sure of how safe your private keys are.
