Discussion Can you control your wallet if you sign in with just an email?
Last week, I signed into a DeFi app with my email, and it created a wallet for me. I didn't have to write down a phrase or anything like that. I funded this wallet and also swapped a few tokens to test it.
If the wallet is accessed via email login, then whoever controls that email controls the wallet. So I don't know if it is as safe as a traditional wallet. This feels a lot like an exchange account rather than a DEX.
The app that I tried claims to be non-custodial. They also say the private key is split into multiple parts, so they can't access it on their own. On Solana, Jupiter also works the same way. You sign in with an email, and it handles the wallet for you.
I am trying these wallets for the first time, so I have a few questions.
Can I export the key and move it to a normal wallet, or is it tied to that one email and the app forever? If you've used one for a while, did you ever actually export it?
