Hey SN,
Founder of CyberHornet here and wanted to share a little more on our Swarm product we announced last week.
Our objective with Swarm is to bring Bitcoin to Layer 3. For us, that means total interoperability between Bitcoin L1 and L2s, secure self-custody wallet design (with the ability to recover from a lost key) and a user experience that means your Grandma can stack sats.
I'm all about building this in the open so even our first testnet release will be available for early access.
