Currently, all Nostr clients store private keys within their apps, whether as a web extension or mobile app.
With Satochip, we provide a secure element to store private keys externally, enhancing security.
This beta version is CLI-only for now, but with positive feedback, we may develop software integration.
For example, you could use Amethyst (or similar apps) with a Satochip NFC smartcard, keeping private keys outside the app—boosting security without sacrificing convenience.
On desktop, Satochip works with a conventional smartcard reader, and with proper integration, a single card could be used across multiple Nostr clients.
Community builders != contractors
The goal here is to incentive the community around a project. People can top up the sats vault for a specific feature. Other can help. Collaborative tool with Bitcoin rewards.
Trust is definitely the main concern.
The company's reputation could be leveraged in this process. If the bounty is clearly defined with specific milestones and KPIs, that might be sufficient.
To manage participation, a whitelist can be implemented. This means that anyone wanting to take part in a specific bounty must be approved by the bounty organizer. Additionally, the number of whitelisted participants working on a bounty can be publicly displayed.
The bounty itself should be complex enough to deter mercenary developers while incentivizing high-quality contributors.

Who on earth is screenshotting their seed phrases? There are plenty of secure solutions for properly storing them: pen and paper (though I wouldn’t recommend it), metal plates, Seedkeeper, KeePass...
h bar for a first post! First time using Stacker.news. Click like a monkey on every buttons :) Don't blame me.
For the more adventurous, you can find compatible JavaCards for just a few dollars. However, be cautious—it's a bit of a jungle, and often the cards sold don’t actually meet the advertised specifications.
Smartcards are incredibly powerful yet often underrated! They can be used to securely store a variety of Bitcoin-related secrets, including your seed phrase, PIN code, and wallet descriptor. All of this data is safely stored within the secure element, and access to the memory is protected by a personal PIN code, ranging from 4 to 16 characters.
