SATSLINK: Multipurpose Communications Device by Coinkite

• "At its core, Satslink is a peer-to-peer, hackable multi-purpose device. It features a secure element, as typical of Coinkite products, allowing the user to securely store private keys within the device."

"Being dissatisfied with the connected and DIY options, we felt the need to create a better hot platform. Bitcoin is expanding scripting/mpc options and we now have Nostr. Someone had to make a good connected and portable device for developers and enthusiast to create the next generation of freedom functionality,” NVK, founder at Coinkite, told Bitcoin Magazine.

• “The initial target is developers and enthusiasts,” NVK said. “But, because of the consumer friendly form factor, they will be able to start using anything the community creates. Like hot and sovereign lightning wallets and Nostr clients!”
• SATSLINK is priced at $189.99 and is currently available for pre-order on Coinkite's store.
