Secrets are stored in Secret structs that automatically zero out memory when dropped:
use secrets::memory::Secret;
let secret = Secret::new("sensitive_data".to_string());
// ... use secret.expose() ...
// Memory is wiped when `secret` goes out of scopeProtocol-level security: .env contains pointers, not actual secrets:
use config::advanced::{AdvancedConfig, SecretPaths};
let config = AdvancedConfig::from_env();
if config.secret_paths.is_configured() {
// Fetch from Vault using configured paths
let jwt = vault.get_secret(&config.secret_paths.jwt_path.unwrap()).await?;
let db_creds = vault.get_dynamic_creds(&config.secret_paths.db_path.unwrap()).await?;
} else {
// Fall back to auto-generated secrets (development mode)
let jwt = std::env::var("JWT_SECRET")?;
}Config-driven limits prevent catastrophic failures:
use config::advanced::AdvancedConfig;
let config = AdvancedConfig::from_env();
// Check withdrawal limit
config.safety_controls.check_withdrawal_limit(50000.0)?; // β
OK
config.safety_controls.check_withdrawal_limit(150000.0)?; // β Err: exceeds limit
// Check if system is paused
config.feature_flags.check_global_pause()?; // Blocks all operations if pausedToggle features without redeployment:
let flags = &config.feature_flags;
flags.check_bridge()?; // Returns error if bridge disabled
flags.check_airdrop()?; // Returns error if airdrop disabled
if flags.debug_mode {
println!("Debug info available");
}Built-in metrics collection:
use utils::metrics::get_metrics;
let metrics = get_metrics();
metrics.increment_secret_fetches();
metrics.increment_transaction_validations();
// Generate Prometheus output
let prometheus_output = metrics.generate_metrics();
// Available at: http://localhost:9090/metricsEnable background rotation loop:
use config::advanced::AdvancedConfig;
let config = AdvancedConfig::from_env();
if config.feature_flags.auto_rotation_enabled {
tokio::spawn(secrets::rotator::rotation_loop(
config.rotation_config.refresh_interval_secs
));
