Question for limitations in the use of MOVE in TESTNET

Hi,

I want to get some experience with MOVE.

So I wan’t to try to write some Contracts similar to ERC20 Contracts in Ethereum or similar to an ERC721.

I have seen that the etoken.mvir implementation only has some asserts in the code.

Is it true, that up till now, you only have the Chance to write and test contracts and not to interact with them?

If this is true, can you tell me when a testnet with less limitations would be published?

Is my idea general valid? So Is it possible to have own contracts implementing own Tokens (like a real Euro on Libra Stable Coin)?
