This repository is a React Native library that integrates Paystack payment processing into mobile applications using a WebView-based modal. It provides a `PaystackProvider` component that wraps the app and exposes a `usePaystack` hook for initiating transactions. The library handles parameter validation, generates an inline Paystack checkout page, and communicates payment events back to the app via WebView postMessage. It also supports deep linking for payment channels like Zap, intercepting specific URLs and opening them via the OS. The architecture follows a Provider pattern with context, making the payment functionality accessible throughout the app. The code is written in TypeScript with full type definitions and includes a test suite using Jest. However, the package.json contains unrealistic dependency versions (e.g., react@^17.0.1) indicating potential maintenance issues. The core utility functions for URL routing and external URL opening are well-designed and could be reused in other projects.
