The Cashu protocol

Cashu is an open Ecash protocol for anyone to implement. The specifications, called Cashu NUTs (Notation, Usage, and Terminology) describe how to implement the protocol. Multiple Cashu client libaries make it easy for developers to write their own wallets.

  • Nutshell is the reference mint implementation in Python.
  • Cashu-rs-mint is a mint implementation in Rust using CDK.
  • Chamberlain is a mint implementation with an Integrated LDK Node using CDK.
  • Moksha is a Cashu wallet and mint written in Rust.
  • Gonuts is a mint written in Golang.
  • nutmix is another mint written in Golang.
  • Coconut is a Cashu mint written in Zig.
  • Cashubrew is a Cashu mint written in Elixir.

Wallets

  • Nutshell is a CLI wallet available through PyPi. It comes with builtin Tor, supports multiple mints, and can send and receive tokens on nostr, and supports pay-to-script-hash (P2SH) tokens.
