New mint need a credit for Solana

[berscoin]

Hello,

I test :

const mint = await spl.Mint.create(connection, 6, alice.publicKey, alice);

I got an error : Transaction simulation failed: Attempt to debit an account but found no record of a prior credit
I think that first, I should airdrop some lamports for Alice to do this.

But if Bob also has no sol/lamports how he can transfert to Alice ?
Maybe solution is to create one main account who can pay all fees of these transactions without airdroping sol to everyone ? But is it possible?

Thanks in advance.
