Now the only problem is getting some Testnet4 coins. For some reason the faucet on mempool.space blocks me from getting any.

If you want an easy way to access Testnet4, looks like Melvin Carvalho has got you covered.

Of course, you can also download Bitcoin Core and set `chain=testnet4` or `testnet4=1` in your bitcoin.conf file.
