Blockaid Onchain Monitoring is a security platform designed for monitoring and protecting blockchain assets and infrastructure. The platform provides real-time visibility into threats across smart contracts, wallets, treasury wallets, multisig wallets, sequencers, externally owned accounts (EOAs), mempools, validators, and bridges. The system uses machine learning models to detect various threats including malicious transactions, malicious tokens, compromised frontends, suspicious function calls, multisignature approvals, suspicious transfers, MEV attacks, majority collusion attacks, and liquidity anomalies. It monitors the entire web, wallet interactions, and critical blockchain infrastructure components. The platform enables automated incident response through custom workflows and real-time alerts. Response capabilities include alerting security operations teams via Slack, denying cosigner signatures, unwinding positions, revoking approvals, changing parameters, pausing contracts, and notifying third-party wallets. Investigation features include analysis of money laundering patterns, OFAC interactions, and comprehensive incident reports with detailed audit trails. The platform provides automated threat analysis to reduce investigation time. Compliance capabilities include automated reporting and comprehensive audit logs to meet regulatory requirements. The platform is integrated with web3 wallets and interfaces, providing visibility across the blockchain ecosystem. Deployment is designed to be completed in under 20 minutes with flexible APIs and engineering support.
