+
+**Fuel Agent Kit** is an open-source AI agent toolkit designed specifically for the [Fuel](https://fuel.network) network. It enables AI agents (powered by LangChain, OpenAI, Anthropic, or Google GenAI) to autonomously interact with the Fuel blockchain, execute transfers, trade on decentralized exchanges (Mira DEX), and fetch real-time Pyth network data.
+
+---
+
+## ⚡ Features
+
+* **AI-Ready Infrastructure:** First-class integration with `@langchain/core`. You can plug these tools directly into your `AgentExecutor`.
+* **Asset Transfers:** Secure and autonomous `transfer` functionalities built on top of the official `fuels` SDK.
+* **DeFi Integrations:** Pre-built modules to interact with **Mira Dex** (`mira-dex-ts`) and fetch accurate oracle feeds via **Pyth Network** (`@pythnetwork/pyth-fuel-js`).
+* **Swaylend Operations:** Supports interactions with lending protocols.
+
+---
+
+## 📦 Installation
+
+To use `fuel-agent-kit` in your project, install it alongside its peer dependency (`fuels`) and your LLM connector of choice.
+
+```bash
+npm install fuel-agent-kit fuels
+```
+
+If you are using LangChain and OpenAI:
+```bash
+npm install langchain @langchain/openai
+```
+
+---
+
+## 🚀 Quickstart
+
+Below is a minimal example demonstrating how to initialize the `FuelAgent` and utilize its built-in tools.
+
+```typescript
+import { FuelAgent } from "fuel-agent-kit";
+import { ChatOpenAI } from "@langchain/openai";
+import { AgentExecutor, createReactAgent } from "langchain/agents";
+import { Provider, Wallet } from "fuels";
+
+async function main() {
+  // 1. Initialize the Fuel Wallet and Provider
+  const provider = await Provider.create("https://mainnet.fuel.network/graphql");
+  const wallet = Wallet.fromPrivateKey(process.env.FUEL_PRIVATE_KEY!, provider);
+
+  // 2. Initialize the Fuel Agent Kit
+  const agentKit = new FuelAgent({
+    wallet: wallet
+  });
+
+  // 3. Extract the LangChain-compatible tools
+  const tools = agentKit.getTools();
+
+  // 4. Set up your LangChain standard agent
+  const llm = new ChatOpenAI({ temperature: 0 });
+  const agent = await createReactAgent({ llm, tools, prompt });
+  const executor = new AgentExecutor({ agent, tools });
+
+  // 5. Run it autonomously
+  const result = await executor.invoke({
+    messages: [
+      { role: "user", content: "Transfer 0.1 ETH to fuel1... address." }
+    ]
+  });
+
+  console.log(result.messages);
+}
+
+main();
+```
+
+---
+
+## 🛠️ Architecture
+
+The toolkit provides highly modular actions under `src/`:
+- `FuelAgent.ts`: The central orchestrator uniting all available sub-modules.
+- `/transfers`: Logic handling native asset and token transfers.
+- `/mira`: Decentralized exchange interactions.
+- `/swaylend`: Lending protocol interactions.
+- `/read`: Data inspection (balances, chain-state, Pyth oracle).
+
+---
+
+## 💻 Contributing

+We welcome community contributions! Please read our [CHANGELOG.md](CHANGELOG.md) for versioning history.
+
+1. Fork the Project
+2. Create your Feature Branch (`git checkout -b dev/AmazingFeature`)
+3. Commit your Changes (`git commit -m 'Add some AmazingFeature'`)
