FailSafe builds autonomous penetration testing and continuous offensive security systems for applications, APIs, cloud infrastructure, and AI. Its SWARM platform deploys threat-model-driven AI agents that discover, chain, and exploit vulnerabilities, with findings mapped to MITRE ATT&CK, OWASP, and NIST CSF.
Sigma Prime performs blockchain security audits and research, auditing offchain code, ZK systems, blockchain infrastructure, and smart contracts. It also offers an embedded security engineer role, security training, and blockchain infrastructure operations, and publishes audit case studies.
Oxygen is a DeFi prime brokerage service built on Solana and powered by Serum's on-chain infrastructure. It lets users earn yield, borrow from peers, trade directly out of their pools and get trading leverage against a portfolio of assets. It uses multiple uses of the same collateral, cross-collateralization and order-book-based pricing.
K3 Capital is a DeFi asset and risk manager that has deployed liquidity on-chain since 2021. It runs non-directional strategies focused on interest-rate arbitrage, liquidity provisioning and early-stage protocol participation, and offers the Absolute USD Return Fund, Enhanced ETH Fund and BTC Yield Fund. Its Labs arm has contributed to projects including sBOLD and Gearbox.
Statemind is a blockchain security firm offering smart contract audits and security work, with stated expertise in Solidity and Vyper. Its audit process is described in five steps, from project review and code checks through interim reports and final verification.
BlockSec Phalcon Security is a platform for protocols, liquidity providers and traders, L1/L2 chains and exchanges to detect attacks, receive alerts and take automatic actions. It scans transactions at the mempool stage and can place a transaction ahead of an attack to block it. The site describes configuration by importing addresses or using templates.
Blockaid is a real-time onchain security platform for web3 builders. It offers transaction security, address scanning, token scanning and dApp scanning, and combines its data network with a policy engine so threat verdicts reflect both its intelligence and customer policies. It also lists end user protection, onchain monitoring, crypto fraud prevention and cosigner products for wallets, DeFi operators, exchanges, banks and asset managers.
