+### [Stellar AppKit](https://github.com/SagantaHQ/stellar-appkit)
+
+**Stellar AppKit** is an open-source, framework-agnostic application SDK for building Stellar dApps. It provides a unified application layer for wallet connectivity, authentication, session management, transaction UX, and Soroban.
+
+Unlike wallet connectivity libraries that primarily focus on connecting applications to wallets, Stellar AppKit is designed to provide a broader set of application-level primitives.
+
+Key features include:
+
+- Unified Stellar wallet connectivity
+- **Sign in with Stellar** authentication
+- Server-side authentication and session validation
+- Session management
+- Transaction previews, simulation, and risk detection
+- Soroban transaction lifecycle abstractions
+- Desktop modal and mobile bottom-sheet wallet UX
+- UI integrations for **React, Vue, and Svelte**
+- Support for **25 languages**, including Chinese
+- Framework-agnostic core SDK
+
+Stellar AppKit's published roadmap includes:
+
+- A React Native bottom-sheet UI with Expo compatibility
+- A smart-account/passkey signer and gas-sponsorship hook for the Soroban invoke pipeline
+

 A stripped-down wallet where you can check an account’s XLM balance and send simple payments on Testnet and Mainnet. Account Viewer's [source code](https://github.com/stellar/account-viewer-v2) is also useful and instructive for developers building wallet-related features into their applications.

 ### [NEAR Intents](https://docs.near.org/chain-abstraction/intents/overview)
 
-NEAR Intents is a multichain transaction protocol for wallets that allows users or AI agents to simply state the outcome they want (like swapping Token A for Token B), and then lets a network of off‑chain market makers (called solvers) compete to fulfill that request; once the best solution is selected, it is sent to the user for approval, then execution is verified and executed through a Verifier smart contract on NEAR.
