Pre-transaction Simulation

Pre-transaction simulation explains what an unsigned transaction is expected to do before the user signs or broadcasts it.

The intended flow is:

  1. A wallet or application prepares an unsigned transaction.
  2. SUMUN simulates the call against a selected chain state.
  3. The result summarizes execution, state changes, asset movements, approvals, and risk signals.
  4. The user or integrating wallet decides whether to continue.

Relevant signals can include unlimited approval, unexpected asset transfer, privileged upgrade calls, dynamic external calls, delegate calls, and reverts.

The public simulation API is currently in Preview. A simulation reduces uncertainty but cannot guarantee final mined execution or safety.
