What multicall does on Tron

ParameterTypeRequiredDescription

Parameters from the server's own tool schema.

Why multicall needs a policy

The tool explicitly states it executes 'read-only functions', meaning it only retrieves data from the blockchain without any side effects. Despite the word 'Execute' in the description, the 'read-only' qualifier makes this a Read operation. The batch nature doesn't increase severity since no writes occur.
