Hi, I've read (from Stellar-base Python SDK quickstart : https://stellar-base.readthedocs.io/en/latest/quickstart.html#using-the-stellar-live-network ) that we have to make the operation "createAccount" in the transaction in order to activate an account which hasn't any xlm yet. What if we send lumen to that account the usual way ? Without the operation "createAccount" Thanks for your time, Darosior

Yes that's why i'm asking the behaviour of a transaction of a transaction send to such an account

Tx to create an account

From my understanding, the account isn't active on the network if you just post it to the random generated key pair.

Then it will fail.
