So how do you see it: we take the Specter's codebase to build on top of it, but it's not a Specter anymore or what? The original repository is under MIT license, I don't see an issue here.
Just pushed the full v1.0.1 “Enclave-Merge” release a few minutes ago, if you refresh the repo you’ll see the Secure Enclave code baked into the main tree, not just the README tweaks you diff-ed earlier.
🚀 v1.0.1 “Enclave-Merge” released – Secure Enclave signer now in main tree.
Key points
- Mac Secure Enclave key + Touch ID = 1 cosigner
- 2-of-3 multisig wizard (add Coldcard, SeedSigner, etc.)
- No cloud, no telemetry – PSBT via QR/NFC

We haven’t published a formal roadmap yet. We’re still collecting early feedback before locking down priorities. If there’s something specific you want to see, let us know (or open an issue/feature request). We’ll post a proper roadmap to the GitHub repos and Wiki soon. Thanks for the nudge!
The fee subtraction logic in create_psbt incorrectly always subtracts from the first recipient, ignoring the subtract_from parameter. This can lead to misconfigured transactions. and Command Injection via subprocess.Popen with shell=True
Good catch, thanks for bringing these up.
Fee subtraction logic: You're right; the current implementation overly simplifies and defaults to the first recipient. We're tracking this and are actively working on a patch to correctly respect the subtract_from parameter across multiple recipients.
subprocess.Popen with shell=True: We're aware of this. Although our current usage sanitizes inputs thoroughly, using shell=True isn't ideal from a security perspective.
Really appreciate the scrutiny. If you're open to it, we'd welcome a PR or a deeper security review from your side - happy to discuss a bounty for quality fixes too!
Hey, thanks for pointing that out, but don’t worry, nothing malicious going on.
The main Specter Desktop repo you're looking at only had its README updated because that's just a fork reference. The actual Secure Enclave integration code is entirely in our dedicated specter-enclave repository:
Everything there is open source and MIT-licensed, and the binaries we distribute are reproducible from that code. Definitely take a look yourself, we encourage reviews, audits, and any scrutiny!
Let me know if you have more questions or find anything unclear - I’m happy to walk you through it!
Yep, that’s ours.
We host the .dmg on https://downloadmacos.com to keep the file delivery fast and signed from a domain we control (GitHub's CDN had some issues with visibility in certain regions).
The build itself is fully open-source and reproducible - the exact source code is on GitHub.
As for the Secure Enclave - yeah, Apple actually exposes a really nice interface for it through CryptoKit. It’s limited (by design), but more than enough to generate and safely seal a Bitcoin key inside the chip. You just can’t get the key back out, which is kind of the point :)
Let me know if you want a walkthrough or want to poke at the code - happy to dive deeper.
It seems there was an issue with the repo visibility, I've re-uploaded it to https://github.com/CryptOpenDevelopment/specter-enclave
The Touch ID / Secure Enclave magic isn’t in that two-commit demo branch at all. All the code lives in a separate module (specter-enclave) that we keep in its own repo and pull in at build time. The README edits just point macOS users at the notarised DMG. Nothing is “only in the binary” , you can reproducibly rebuild the exact same DMG from source in about 15 minutes.
