Make the newly created wallet visible on the chain

If you are running out of funds for test purposes, I’d recommend working on a local node. This way you can use your own genesis wallet and seed funds programatically. Obviously this is not possible in a live testnet.

@danielbate In this case, is it possible to make it look like paymaster?

Could you elaborate on the scenario please?

Additionally, you could use a predicate to transfer funds where the predicate could also pay the fees of the transaction, check out this test case that we use internally.
