Blockaid
Blockaid is a web3 security company that acts as a real-time trust layer for onchain finance, simulating and validating blockchain transactions before they execute to stop scams, drainers, exploits, fraud, and compliance risks. Its detection engines are embedded inside major wallets, exchanges, and protocols - including Coinbase, MetaMask, Uniswap, Stellar, and OKX - screening hundreds of millions of transactions a month and protecting hundreds of billions of dollars in digital assets. Founded in 2022 by former Israeli cyber-intelligence operators, the New York- and Tel Aviv-based company has raised roughly $89 million and is expanding from consumer wallet protection into institutional compliance infrastructure.
Merkle Science
Merkle Science is a blockchain analytics and predictive risk intelligence company that helps crypto exchanges, financial institutions, government agencies and Web3 businesses detect, investigate and prevent illicit cryptocurrency activity. Founded in Singapore in 2018 by Mriganka Pattnaik and Nirmal Ak, it uses behavior-based machine learning rather than static blacklists to power its two core products - Compass for real-time transaction monitoring and compliance (AML/KYC/CFT), and Tracker for cross-chain forensic investigations across 10,000+ assets and 200+ bridges.
Veridise
Veridise is an Austin-based blockchain security company spun out of the UToPiA program-analysis research group at the University of Texas at Austin. It hardens Web3 by pairing expert human auditors with proprietary tools built on formal methods, fuzzing and program analysis. Veridise audits smart contracts, zero-knowledge circuits, blockchain implementations and dApps, and has completed 150+ audits for infrastructure protocols including Scroll, Linea, Succinct, Manta Network, RISC Zero and Semaphore.
Drosera Network
Drosera Network is a decentralized incident response protocol that aims to be an 'immune system for Ethereum.' It lets DeFi protocols deploy 'Traps' - small, off-chain-defined smart contracts that continuously monitor on-chain state, detect anomalies or exploits, and trigger automated emergency responses (like pausing functions) before an attack drains funds. A decentralized network of Operators watches those Traps and pushes verified responses on-chain, turning security from an after-the-fact audit into a live, programmable defense layer.
