Lightwalletd

A stateless server that serves light clients with blockchain information. It fetches blockchain data from zcashd, processes them to reduce data, and stores it in a database. This allows light clients with different requirements to get relevant data without interacting with zcashd directly.

Resources

Quick info

  • Parallelize-able, stateless, and containerized
  • Can run virtually on the cloud (EC2, GCP, AZURE, Docker, etc.)
  • Not using load balancers, orchestrators, schedulers (yet)
  • Metrics, stress tests, and testing done (ask us)

Android

We maintain a SDK that allows for wallet functionalities (address management, send, receive, etc.), documentation of the APIs, and a demo app that exercises the SDK.

Resources

Quick info

  • Native Android SDK and app, written in Kotlin
  • Architecture: targeting ARM64, ARMv7 and x86
  • APIs: We support API 16+ but we optimize for API versions 21+
  • Android SDK Threat Model

iOS

We maintain a SDK that allows for wallet functionalities (address management, send, receive, etc.), documentation of the APIs, and a demo app that exercises the SDK.

Resources

Quick info

  • Native iOS SDK and app, written in Swift
  • Less mature then Android SDK but working towards parity
  • Targeting the latest (past two 2 years) iPhones

WASM

A minimal functioning demo web wallet that allows desktop OSes to use shielded addresses and separates web-specific wallet functionalities.
