Hey Stacker friends 👋

After some serious trial and error, I finally got Specter Desktop v2.1.1 running smoothly on Start9 – and yes, it works with Bitcoin Core v28! This was a missing piece for many who wanted to run the latest Bitcoin Core while using Specter for multisig and hardware wallet setups.
🛠️ What I did:

Forked Start9Labs/specter-startos

Updated Specter to v2.1.1

Switched to the new start-sdk build process (since embassy-sdk is deprecated)

Adapted the Makefile accordingly

Verified everything with a successful build and sideloaded .s9pk on my Raspberry Pi

🧪 The Result:

Works like a charm!

Integrated with Bitcoin Core v28

Pull request submitted: #56 on GitHub

Repo: Funman2/specter-startos

💡 Why this matters:

Specter is one of the best tools for managing multisig setups with hardware wallets. Getting it to work with modern Bitcoin Core versions on Start9 opens up a lot of flexibility and keeps sovereign stack users up to date.
🤝 Help wanted:

Test the .s9pk if you’re running Start9
