3F Mutual supports crypto risk protection, bug bounties, coverage, or security review workflows.
Blockhead is a crypto portfolio tracker, cross-EVM block explorer and interface for dapps and web3 infrastructure. It supports tracking tokens, NFTs and DeFi balances, and provides charts for visualising web3 activity. It covers Ethereum and other Ethereum Virtual Machine-based chains.
API3 provides data feeds and pays dApps for using them. It reports more than 100 data feeds on every chain. AirnodeHub is described as a marketplace where agents discover, call and pay for APIs, with the data source paid for each response. It is in early access and expected to keep changing and pivot.
Cyfrin is a blockchain security firm helping protocols and institutions reduce risk through smart contract audits, formal verification, penetration testing, incident response, and security and risk advisory. It also provides security research and enterprise education and certifications.
Web3 Antivirus is a security suite for Web3 users. It includes a browser extension, a MetaMask Snap, a free security API, wallet risk analysis, and an address poisoning monitor, aimed at protecting against phishing, wallet drainers, and other blockchain threats.
DeFiSafety helps with crypto security, portfolio tracking, auditing, risk monitoring, or asset protection.
AlphaPing operates mandate-driven, non-custodial on-chain credit vaults with defined risk boundaries and verifiable on-chain accounting. Vaults include USDC- and LINK-denominated mandates that apply over-collateralized credit, programmatic liquidation, isolated risk compartments and deterministic exit rules. The project states its vaults target institutional use cases and are not intended for discretionary trading, yield aggregation or retail-oriented speculation.
