prepare_tx
ActiveTool of gulltoppr
declared in 0.1.2
Prepare a contract WRITE for the user to sign. Returns an UNSIGNED transaction, its simulation, a human-readable summary, an abi.ninja signing deeplink, and warnings. IMPORTANT: this tool NEVER signs or broadcasts. Present the summary + simulation + warnings to the user and hand them the `deeplink` — they sign in their own wallet. If `warnings` is non-empty (decompiled ABI, proxy, or a reverting simulation), surface it.
