Blockaid Crypto Fraud Prevention is a fraud detection solution designed for cryptocurrency exchanges, fintechs, and banks. The platform monitors both onchain and offchain signals to detect and prevent crypto fraud schemes, with specific focus on pig butchering scams and money muling activities. The system uses a unified engine to track threat signals across fake investment sites, social engineering scams, onchain exposures, and behavioral patterns. Detection algorithms work even when blockchain addresses are new or user patterns are limited, predicting malicious intent before funds move. The platform provides real-time monitoring and detection capabilities that identify fraud patterns early in the attack lifecycle rather than after funds have been transferred. It includes investigation tools that provide intelligence and visual links to help fraud teams analyze and resolve scams. Blockaid offers REST APIs and SDKs for integration, with continuous threat updates and dedicated engineering support. The solution is integrated with web3 wallets and interfaces, allowing the system to access data across the cryptocurrency ecosystem and block threats directly on its network. The platform supports multiple blockchain networks including Ethereum Mainnet, Base, Optimism, Polygon, and other EVM chains. It provides a unified interface for fraud, security, product, and engineering teams to collaborate on fraud prevention efforts.
