A physical cartridge that lets you use your GameBoy as a cold storage wallet, generate mnemonic phrases and save them securely offline. No firmware updates ever.

With all the drama around the recent Ledger hardware wallet update, we realized the need for truly offline cold storage that minimizes trust. What started as a fun idea now seems to be a really important product. Trusting the supply chain for new security devices can be scary because we don’t know who has messed with a device, but I know exactly where the GameBoy on my shelf has been for the last 20 years. I’m hoping Game Wallet will be a fun way for more people to take their private keys completely offline. The future of digital sovereignty is in your hands. Packaged in a truly offline hardware wallet with the certainty of no firmware updates.

This is probably one of the most unique things I've seen in a long time! Please tell me how you came up with this idea?

Ha! Cool! How much will it cost? And does the cartridge work for the NDS too? (The GBA game port, of course)

@anna_0x Thank you!! We're still working on the exact price because its going to depend on the supply chain, that will be announced really soon. No DS support, but maybe other devices in the future.

very fun I love the 2nd life it gives it.

This is really awesome. I like the retro love as well as the tech and message. Nothing is more reliable than a GB cartridge 😬😀 Almost no need to write down the seed. And open source? 🧐 Sign me up!
