I right away want to apologize if I ask something silly. The entire Blockchain topic is a bit more complicated than I thought
I just installed MetaMask in my browser and got the option to create a new wallet or use an existing seed. As I meanwhile have an app on my smartphone and one on my desktop, I already know the procedure to have all showing the same wallet, so I opted the “i have a seed”.
After entering my seed phrase, the balance was zero. It was then that I realized, that it would not really make sense to enter the seed of a BITCOIN wallet in MetaMask, as this is on a completely different blockchain, thus showing ETH instead.
The wallet that I used as seed is a “Trust Wallet”, potentially keeping different coins, including ETH - but I have none in there. So the zero balance would be expected. Right?
Did I by this operation create a new wallet in the Ethereum Chain with the same(?) fingerprint as the wallet on the Bitcoin Blockchain? Will this cause problems in the future if I ever do cross currency trade? Or is this the expected behaviour, as “Trust Wallet” states that “all currencies share the same seed” anyway?
Since the phrase does recreate the private key out of nothing, could I have connected someone else’s wallet by entering a (valid) phrase that has not been “created” before? There was no hint like “this wallet does not exist, do you want to create it?” or such.
But IF I once fill one of the wallets with ETH, should they show up in both, as “they are the same because they share the same seed”?
Yes, I’m a rookie. :-/
