blockINT review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

blockINT is a blockchain intelligence platform from Block6IQ for cryptocurrency investigation and forensics. It is aimed at investigators, law enforcement, and security researchers who need to examine Ethereum activity, identify wallet entities, or follow transaction flows. Access is cloud-based through the web and API, and the product also includes community threat reporting through its C3 database, where suspected crypto fraud can be reported anonymously and without charge.

Its investigation capabilities combine Ethereum transaction monitoring and a block explorer with wallet address investigation, entity identification, transaction graph visualization, and fund-flow tracing. DeFi position tracking, risk scoring, sanctions screening, community threat reports, and watchlist management extend that workflow from tracing into risk review. The API supports address and domain screening, report search, and batch screening of up to 50 addresses. Those features make blockINT a fit for teams whose work centers on Ethereum wallet analysis and screening, rather than organizations seeking documented coverage across multiple chains.

Pricing is usage-based for API screening: the vendor lists a cheapest paid request at $0.01, with API access through x402 micropayments or an API key. The vendor also states that API keys include 10 free calls per day, while fraud reporting is always free. This structure gives occasional users a low-cost way to make paid checks and lets people submit community reports without a fee, but regular screening requires attention to usage and payment method. Choose blockINT when Ethereum-focused tracing, screening, and fraud reporting align with the investigation; teams needing broader blockchain coverage should consider an alternative with documented multi-chain support.
