Welcome to 21.dev 🧰

Equipping developers with the tools they need today to build the Bitcoin apps of tomorrow.

🚧 Pardon Our Dust 🚧

This organization is the new home for swift-secp256k1 (previously known as secp256k1.swift).

Although things might appear sparse at the moment, we are actively renaming our libraries to better adhere to assumed package standards and transferring some repositories from their current locations. These changes are intended to provide a more stable developer experience moving forward and minimize potential disruptions.
