**De.Fi has launched Advanced Shield**, an automated security tool designed to protect crypto wallets from common vulnerabilities. The platform addresses a critical security gap: forgotten token approvals that can lead to wallet drains months after initial authorization. **Key features include:** - Instant vulnerability detection across all connected wallets - Automatic flagging of risky token approvals - One-click bulk revocation of suspicious permissions - Continuous 24/7 wallet monitoring - Multi-chain scanning across 40+ blockchains The tool consolidates all active approvals into a single dashboard, eliminating the need to check multiple blockchain explorers. Users can set up protection once and maintain ongoing security without manual intervention. [Try De.Fi Shield](http://de.fi/shield)

De.Fi has introduced a **Wallet Health Widget** that provides users with a security score ranging from 0-100 for their crypto wallets. The widget functions similarly to a credit score but focuses on wallet security. It highlights risk issues in red and provides recommended actions to address vulnerabilities. Key features include: - Instant health score assessment - Clear identification of security risks - Actionable recommendations for improvements The tool is designed to help users navigate DeFi with greater confidence by making wallet security more transparent and manageable.

De.Fi has introduced a new approval management system that helps users identify and revoke risky smart contract permissions. **Key Features:** - **Filter by Risk**: Sort approvals by date, exposure level, contract name, or security issue - **Pool Search**: Look up any pool by name or contract address to verify safety - **Issue Tab**: One-click access to all unsafe approvals without manual searching The tool flags risk levels (Low/Medium/High) and allows instant revocation of dangerous permissions. Users can access it through More > Approvals in version 8.29. **Common High-Risk Approvals Detected:** - Unlimited token transfer permissions - Staking/withdrawal access rights - Contract upgrade backdoor permissions - NFT transfer/burn rights The platform recommends regular checks as some authorized DApps may retain access to funds even after initial approval.

**The Problem**: Most DeFi users unknowingly maintain dozens of active token approvals—essentially leaving digital doors unlocked for potential exploits. **The Solution**: Advanced Shield provides automated protection by: - Scanning wallets across 40+ blockchains for active approvals - Identifying risky or outdated permissions - Enabling one-click bulk revocation of suspicious access - Organizing all approvals in a unified dashboard **How It Works**: 1. Connect your wallet 2. Automatic scan detects all active approvals 3. Revoke access from unused or suspicious dApps instantly The tool includes a Wallet Health Score and detailed exploit reports, eliminating the need to manually check multiple blockchain explorers. All operations are executed on-chain for transparency and security. [Check your wallet with DeFi Shield](https://de.fi/shield)
