Building ZK Apps That Run on Your Phone

" summary

Morro packages Rust code into mobile bindings and ties into Circom, Halo2, Noir and RISC Zero so circuits compile once and run on iOS/Android; the CLI workflow is literal: morro init / morro build / morro create scaffolds a Rust workspace, generates per-architecture iOS/Kotlin bindings and mobile app templates, and supports Swift/Kotlin/Dart SDKs; examples include geolocation, Semaphore membership, Aadhaar QR, and a RISC Zero ECDSA proof that runs on-phone in 90–120 seconds.
