You need to choose which Solana library you are using, as the setup differs significantly. ## Choose Your Path ### 1. Modern: `@solana/kit` (Recommended) **Use this if:** - You are starting a new project. - You prefer the modern, lightweight, functional API of `@solana/kit`. - You want better tree-shaking and smaller bundle sizes. **Instructions:** [Open Solana Kit Guide](./solana-kit.md) ### 2. Legacy: `@solana/web3.js` (Maintenance Mode) **Use this if:** - You are maintaining an existing project heavily reliant on `@solana/web3.js` v1. - You need specific legacy dependencies that haven't migrated to `@solana/kit`. - You understand that `@solana/web3.js` is heavier and no longer the primary recommendation for new apps. **Instructions:** [Open Solana Web3.js Guide](./solana-web3js.md) ## Quick Comparison | Feature | `@wallet-ui/react-native-kit` | `@wallet-ui/react-native-web3js` | | :--- | :--- | :--- | | **Solana Lib** | `@solana/kit` | `@solana/web3.js` (v1) | | **API Style** | Functional, Tree-shakeable | Object-Oriented, Monolithic | | **Bundle Size** | Smaller | Larger | | **Status** | **Recommended** | Maintenance / Legacy Support | --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/wallet-ui) — claim your Tome and manage your conversions.
