Blockaid, founded in 2022 and headquartered in Tel Aviv, provides real-time transaction and application-layer threat detection for wallets, exchanges, and decentralized apps, protecting end users from phishing, scams, and malicious smart contracts. The company delivers its security as an embeddable API/SDK that simulates and screens transactions before signing, rather than relying on after-the-fact blockchain forensics once funds have already moved.
Blockaid has raised through a Series B with credible named customers including MetaMask and OpenSea, and backing from top-tier investors — real, verifiable adoption at meaningful scale in the Web3 ecosystem. Its durability, like most Web3-specific infrastructure, is tied to continued crypto and Web3 adoption more broadly rather than being independent of that market’s trajectory.
