Module sui::protocol_config

This module provides access to protocol configuration feature flags. Feature flags control the availability of various protocol features and are enabled/disabled at specific protocol versions during epoch changes.

Function is_feature_enabled​

Checks if a specific protocol feature flag is enabled.

Restricted to internal use within the sui-framework package only. If we need to use it in sui-system, we can add friend declarations. We should never need to expose this to user packages.

Arguments​

  • feature_flag_name - The name of the feature flag as bytes (e.g., b"enable_vdf")

Returns​

  • true
    if the feature is enabled in the current protocol version
  • false
    if the feature is disabled

Aborts​

  • Error code 0: Feature flag name not found
  • Error code 1: Invalid feature flag name (not valid UTF-8)

Example (for framework use only)​

use sui::protocol_config;

if (protocol_config::is_feature_enabled(b"enable_accumulators")) {
// Accumulators are available
};
public(package) fun is_feature_enabled(feature_flag_name: &vector<u8>): bool
