Description

AegisWeb3 is a free cybersecurity browser extension incubated by PeckShield, a leading blockchain security company. It provides real-time protection against scam tokens and phishing websites, safeguarding users during activities such as swapping, minting, staking, and exploring Web3 on Chrome. The extension continuously monitors for malicious threats and offers tools to inspect transactions, revoke risky approvals, examine smart contracts, and report scams.

Features

  • Real-time Anti-phishing: Advanced machine learning algorithms scan for suspicious activity 24/7, detecting and blocking sophisticated phishing scams before they compromise your crypto assets. This is especially useful when browsing unknown dApps or clicking links in social media messages.
  • Transaction Simulation: Before you sign a transaction, AegisWeb3 simulates it and displays the expected outcomes, such as token transfers or approval changes. This brings clarity and certainty when dealing with complex signatures, helping you avoid malicious contract interactions.
  • Approval Revoke: You can inspect all token approvals granted to dApps and revoke those that are risky or no longer needed. This prevents potential threats to your funds by terminating permissions that could be exploited.
  • Smart Contract Examination: With one click, you gain insights into a contract's security, liquidity, and transaction flow. This is useful before interacting with a new token or DeFi protocol to assess its legitimacy.
  • Report Risks: Users can report blockchain scams, such as phishing websites or scam tokens, directly through the extension. The AegisWeb3 team follows up and verifies reports, contributing to community safety.

AegisWeb3 currently supports Ethereum, BNB Chain, Polygon, and Fantom, with plans to add Avalanche, Arbitrum, Optimism, and Cronos in the future. This multi-chain support allows users to stay protected across various ecosystems.
