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.
Ido Ben-Natan
Ido Ben-Natan is the co-founder and CEO of Blockaid, a blockchain security company that protects crypto wallets, apps and users from scams and onchain exploits in real time. A veteran of Israel's Unit 8200 and the Office of the Prime Minister, where he led a cyber security R&D team and won the Israel Defense Prize, he launched Blockaid in 2022 to bring nation-state defensive expertise to Web3. The company is trusted by Coinbase, MetaMask, Kraken, Uniswap and Stellar, and has raised roughly $89 million from investors including Ribbit Capital, Sequoia, GV and Greylock.
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.
Fernando Reyes
Fernando Reyes, known on-chain as FDR, is the founder and CEO of Drosera Network, a decentralized incident response protocol building what he calls an 'immune system' for Ethereum. A former US Army Cyber Protection Brigade operative, he also founded Groom Lake, a Web3 security firm staffed by ex-military and intelligence personnel that hunts hackers and recovers stolen crypto. In February 2025 Drosera raised $4.75M led by Greenfield Capital to ship its 'Traps' technology - customizable Solidity smart contracts that detect and neutralize exploits before they spread.
