AppKit

AppKit by Reown is a comprehensive full stack software development kit (SDK) designed to streamline the creation of onchain applications with rich user experiences. It enables developers to onboard millions of users quickly by integrating social and email embedded wallets, web3 wallet login, crypto swaps, fiat on-ramp, and multi-chain wallet support. AppKit supports major blockchain ecosystems including EVM-compatible chains, Solana, and Bitcoin, making it a versatile choice for cross-chain dapps.

The toolkit offers a wide range of SDKs for popular frontend frameworks and platforms such as React, Next.js, Vue, Nuxt, Svelte, React Native, Flutter, Android, iOS, and Unity. This broad platform support allows developers to integrate AppKit seamlessly into web, mobile, and gaming environments. Key features include smart accounts, sponsored transactions, and one-click authentication methods like social login and Sign-In with X (SIWX), which simplify user onboarding and transaction signing.

AppKit differentiates itself by providing a chain-agnostic core and embedding wallets directly into apps via social and email authentication, reducing friction for end users unfamiliar with traditional web3 wallets. It also supports Telegram Mini Apps, enabling developers to build blockchain-enabled experiences within Telegram. The SDK requires connection to Reown's proprietary infrastructure and is governed by the Reown AppKit Community License, which outlines usage terms including commercial thresholds and redistribution rules.

Developers can get started by choosing the appropriate SDK for their platform from the extensive documentation and examples provided. Migration guides are available for projects transitioning from Web3Modal versions 1 to 5. The project maintains active development and community support through Discord and GitHub, making it suitable for teams looking to build scalable, user-friendly blockchain applications quickly.
