This demo is adapted from Solana Mobile DApp Scaffold for the tutorial Token-gating Saga Genesis Token. This demo is a mobile dApp development tutorial using Helius DAS API and React Native to token-gate a collection. Follow the tutorial on the Helius Blog.

Install v20.9.0 NodeJS to use yarn.

Install the Android SDK tool and set the ANDROID_HOME variable.

Configure a Saga/Android for mobile development: In settings, tap the Build Number option 7 times until the ‘You are now a developer!’ pop-up is visible. Search and enable Developer Options and enable USB Debugging in the same dropdown.

Open the repository in a code editor and bring up a terminal.

cd app/
