At Frostsnap ❄ we're making
bitcoin self-custody easy.
With Frostsnap you can start with a single device that plugs into
your phone. In the Frostsnap app, you can create a new wallet.
Actions are sent from the Frostsnap app to the device where they are
confirmed.
If you want to upgrade the security of your bitcoin wallet, you can
connect more frostsnap devices and seamlessly upgrade to a
multisignature wallet protected behind multiple keys.
For example, with three frostsnap devices you can create a 2-of-3 where you need to sign on any two of the devices in order to spend funds.
With frostsnap, we've devised a way to create additional access policies to the same wallet, such as a "spending key" where a single device can spend up to some user defined limit per day.
Or a user could create an additional set of multisig keys for inheritance. Suppose you create an additional 3-of-3 and share those keys amongst trusted parties.
Advancements of cryptography allow us to build an upgradable, personalized, and intuitive self-custody experience. Frostsnap is building out this vision.
FROST provides great privacy, scales well with fees, and is malleable (can add or remove signers after key generation!). 🪄 polynomials ❄.
SatSale is a lightweight payment processor written in python -
SatSale.org.
You can connect SatSale to your own Bitcoin node or clightning/lnd
node. SatSale also supports xpubs, lightning addresses, woocommerce
point-of-sales and more! It can be used to spit out unique addresses
like we see around this page (test em).
With blind signatures you can have a server sign something, without
them learning what they have signed. This is powerful for building
coordinators or authorities that respect user privacy.
