How does a crypto change utilise HD wallets in apply?

I perceive that HD wallets at the moment are trade normal. I additionally perceive that “HD” refers back to the know-how of the pockets itself, therefore a HD pockets may very well be omnibus or particular person. This stated, I don’t perceive how this works in apply, and the place limitations apply. Particularly:

  1. I perceive that an change might use omnibus wallets for operational effectivity. E.g. they might conduct inner netting between purchasers in an omnibus to avoid wasting the price of on-chain fuel charges. Nevertheless, if every shopper has their very own little one key pair and due to this fact handle throughout the omnibus, can crypto transfer throughout the HD pockets to completely different little one key pairs? If not, how do they conduct inner netting? If that’s the case, does this imply one might obtain crypto to 1 little one key pair, and merge/ship from a special handle?

  2. Can the grasp non-public key transfer crypto from all of the little one/grandchild key pairs directly, or does it merely exist as a way by means of which to derive little one/grandchild non-public keys?

  3. Will an change usually produce a brand new public key and due to this fact handle for every shopper in an omnibus, or will purchasers generally share the identical key pair in addition to HD pockets total?

  4. If little one key pair A obtained 1 BTC, and little one key pair 2 obtained 2 BTC, the HD pockets would include 3 BTC in keeping with the grasp public key. This stated, if I wished to ship 3 BTC as a single transaction, might I accomplish that? If that’s the case, which handle would the three BTC go away from? (little one key pair A, little one key pair B, the grasp public key, or a brand new public key?)

Thanks upfront, I respect there are a number of questions right here that might not be properly knowledgeable.
