Sorry for this newbie question, but i never was the fully technical interested guy and use cryptos mostly as a USER.
So is it in any way possible to connect for example BTC and LTC in one chain?
And/Or is it possible to "Deposit" BTC in a chain to release the coin xyz - and on the other side a way to burn these new coins to release the "deposited" BTC again?

I really hope u understand what i mean - sorry english is not my passion...
