+
+**MVP Demo:** [safe-tx-simulator.vercel.app ](https://safe-tx-simulator.vercel.app/)
+
+---
+
+**Projects This Work Could Be Useful For 🌍:**
+
+ - **Wallets** – Boosts wallet safety with transaction previews 
+

+
+ - **Ethers.js** – Complements its ecosystem with simulation tools
+
+# Project Overview 📄
+
+## Overview
+
+**Tagline:** Simulate, Secure, Succeed: TxShield prevents Web3 transaction losses.  
+**Description:** TxShield is a transaction simulation platform designed to protect Web3 users from:  
+- Failed transactions  
+- Excessive gas fees alerts
+- Phishing contract detection alerts 
+- Honeypot contract detection alerts  
+
+These issues have cost Ethereum users over **$103 M** from **2018–2024**. Built with **Ethers.js** and **Next.js**, TxShield previews transactions, provides accurate gas estimates, and flags risks such as:
+
+> **High Gas Fees Detected:** Possible Honeypot!
+
+It targets **21 M+ MetaMask and other wallets users if this service implemented in wallets as an API**, enhancing transaction safety and trust across(multiple chains in future to cover the market):  
+- Ethereum  
+- Polygon  
+- Optimism  
+- Polkadot/Kusama (planned)
+
+**Relation to Substrate/Polkadot/Kusama:**  
+TxShield aligns with Polkadot’s vision of a secure, interoperable Web3 ecosystem by providing a safety layer for transactions. While currently Ethereum‑focused, we plan to integrate with Polkadot parachains (e.g., Moonbeam) to simulate cross‑chain transactions, leveraging Substrate’s modularity for custom safety modules.
+
+**Team Interest:**  
+Our team is driven by the mission to eliminate preventable losses in Web3, inspired by real‑world cases like the **$100 K failed transaction incident on Ethereum**. We aim to build trust in decentralized systems, making Web3 accessible and safe for all.

+
+## 🧩 Ecosystem Fit
+
+#### 🎯 Fit in Polkadot/Substrate/Kusama
+TxShield strengthens the Polkadot ecosystem by adding a critical security layer for users interacting with parachains and dApps—especially cross-chain platforms like Moonbeam. By detecting malicious contracts (honeypots, phishing and in the future more) before execution, it directly tackles one of the biggest adoption hurdles in Web3: user trust and transaction safety. This aligns with Polkadot’s vision of a secure, interoperable, and user-friendly decentralized internet.
+
+#### 👥 Target Audience
+- **Primary:** Wallet users (MetaMask, Polkadot.js) seeking safe transactions  
+- **Secondary:** Parachain/dApp developers integrating TxShield’s API  
+- **Tertiary:** Web3 educators & communities promoting secure practices  
+
+#### 🛡️ Needs Addressed
+- Prevents financial losses from scams ($103 M+, 2018–2024)  
+- Reduces gas fee overpayments via precise estimates  
+- Builds user confidence in cross‑chain interactions  
+
+#### 📈 Evidence of Needs
+- **Scam Reports:** Ethereum scam losses highlighted in Etherscan & Chainalysis reports.
+- **Forum Discussions:** Safety tools frequently requested on r/ethereum & Polkadot forums.
+- **Case Study:** A $100K failed transaction (2023) shows urgent need for pre-simulation
