Is Tectum the only real way we scale Bitcoin?

I try to focus on projects that say they aim to scale Bitcoin. I’ve looked at Projects like Stacks which had to pivot cause they realized they couldn’t do what they hoped to. I’ve seen Zenon claim they are going to but yet have a working product. So far Tectum seems to be the only one and ironically it doesn’t actually scale Bitcoin but simply swaps ownership of wallets. It’s an elegant design and I have started to give up that btc can even scale.
