About Blockaid

Blockaid is a security platform that simulates blockchain transactions in real-time to detect malicious behavior before execution. It protects users and wallets from phishing, malware, and scams across chains.

Blockaid is a cutting-edge onchain security platform designed to offer real-time protection against fraud, scams, financial risks, and smart contract exploits. The platform is built to seamlessly integrate with leading wallets, dApps, exchanges, and blockchain protocols, ensuring that both users and infrastructure are safeguarded at every layer of the web3 ecosystem. What makes Blockaid unique is its combination of threat intelligence from both onchain activity and offchain signals, leveraging machine learning and AI to proactively detect malicious behavior.


Launched in 2022 by a team of elite security experts, including former Israeli cyber intelligence operatives, Blockaid has rapidly established itself as a trusted partner for companies like Coinbase, MetaMask, Uniswap, and OpenSea. With offices in New York and Tel Aviv and over $83 million in funding from leading investors like Sequoia and Google Ventures, the project continues to grow and protect the web3 landscape with unmatched precision. Visit Blockaid to explore their full suite of security solutions.

Blockaid is redefining the security standards of the web3 ecosystem by providing a full-cycle platform that monitors, detects, and responds to threats in real time. The solution is deeply embedded across the transaction lifecycle — from pre-transaction simulation to post-event investigation. Unlike traditional web3 security solutions, Blockaid does not rely solely on post-mortem analysis or static audits. Instead, it introduces real-time defense mechanisms that automatically detect and mitigate threats such as phishing, wallet drainers, fake dApps, and OFAC-sanctioned address interactions.


The platform covers a wide range of attack vectors through modular features like Transaction Security, dApp Scanning, Token Scanning, Address Validation, and Cosigner — a component that validates each transaction even when signer devices may be compromised. Clients can also monitor smart contracts, bridge systems, validator nodes, and multisigs with customized rule-based detection engines and automated mitigation workflows. This allows institutions to deploy alerts, revoke approvals, pause contracts, and protect treasury wallets before financial losses occur. More details can be found on Blockaid’s official website.


Blockaid's impact has been proven at scale: with over 3.7 billion transactions scanned, $180 billion in assets secured, and 300 million attacks prevented, it remains one of the most battle-tested security platforms in the blockchain industry. Whether for consumer apps, financial services, or DeFi platforms, Blockaid delivers solutions to meet stringent regulatory requirements and operational needs without compromising performance. Competing platforms such as SlowMist, and Chainalysis provide threat analysis tools, but Blockaid distinguishes itself by its native, real-time integration across leading dApps and wallets.

Blockaid FAQ

  • Blockaid uses internet-wide scanning and sandboxed analysis to identify malicious dApps before they go live. By monitoring new domain registrations, crawling the web, and analyzing user interactions in a controlled environment, it flags risks early—often within minutes—protecting users in wallets like Coinbase Wallet and Rainbow.

  • Yes, Blockaid’s AI-powered detection engine connects onchain behavior with offchain signals to detect organized fraud, including pig butchering scams and social engineering attacks. Its real-time monitoring across dApps, wallets, and exchanges enables proactive threat detection across multiple vectors simultaneously via Blockaid's platform.

  • Blockaid supports EIP-4337-enabled wallets by simulating and validating Account Abstraction transactions in real time. It ensures the accuracy of transaction previews, detects anomalies, and blocks interactions with malicious contracts, enhancing the security layer for smart wallets like those integrated with MetaMask and Backpack.

  • Blockaid provides compliance-grade audit logs and automated reporting tools that help meet AML and OFAC obligations.
