Decentralized options to borrow against Bitcoin holdings?!?

What decentralized options are available for people to permissionlessly borrow against their Bitcoin? I am familiar with crvUSD from Curve Finance and thUSD from Threshold Network, but are there any other options?

I’m particularly interested in solutions that maintain a high level of decentralization and security, without the need for intermediaries. Additionally, it would be helpful to know about any protocols or platforms that might offer competitive interest rates or unique features. With the growing adoption of Bitcoin finance, I believe it’s crucial to explore all possible options.

Could anyone share their experiences or insights on this topic? Are there any emerging platforms or established ones that I might have missed? Your feedback and suggestions would be greatly appreciated.
