How does the addon work?

Foresight API simulates unsigned transactions to classify what they will do if executed. It can provide either a quick English description or a full classified preview with tagged transfers and actions. Developers gain clarity on complex interactions without executing the transaction.

Yes, the Foresight API addon runs simulations and screens for risks before signing. It checks against malicious contract and sanction lists without exposing sensitive data. This enables safer transaction processing.

How to use the addon?

Activate Foresight API via your RPC provider like GetBlock. Use one of its endpoints—describe, preview, or screen—with your unsigned transaction object. You will get back a human-readable summary or detailed simulation and risk assessment.

What services does the addon offer?
