## Feature Flag Implementation

### Backend Feature Flags

```go
type FeatureFlag struct {
    Name        string
    RequiredTrack int
    Description string
}

var FeatureFlags = map[string]FeatureFlag{
    "address_full_detail": {Name: "address_full_detail", RequiredTrack: 2},
    "token_balances": {Name: "token_balances", RequiredTrack: 2},
    "tx_history": {Name: "tx_history", RequiredTrack: 2},
    "internal_txs": {Name: "internal_txs", RequiredTrack: 2},
    "analytics_dashboard": {Name: "analytics_dashboard", RequiredTrack: 3},
    "flow_tracking": {Name: "flow_tracking", RequiredTrack: 3},
    "bridge_analytics": {Name: "bridge_analytics", RequiredTrack: 3},
    "operator_panel": {Name: "operator_panel", RequiredTrack: 4},
    "validator_status": {Name: "validator_status", RequiredTrack: 4},
    "protocol_config": {Name: "protocol_config", RequiredTrack: 4},
}
```

### Frontend Feature Flags

```javascript
const FEATURE_FLAGS = {
    ADDRESS_FULL_DETAIL: { track: 2 },
    TOKEN_BALANCES: { track: 2 },
    TX_HISTORY: { track: 2 },
    INTERNAL_TXS: { track: 2 },
    ANALYTICS_DASHBOARD: { track: 3 },
    FLOW_TRACKING: { track: 3 },
    BRIDGE_ANALYTICS: { track: 3 },
    OPERATOR_PANEL: { track: 4 },
    VALIDATOR_STATUS: { track: 4 },
    PROTOCOL_CONFIG: { track: 4 },
};
```

## Permission Mapping

    "weth.wrap",
    "weth.unwrap"
  ]
}
```

}
```

## Feature Gate Logic

### Backend
```go
func HasAccess(userTrack int, requiredTrack int) bool {
    return userTrack >= requiredTrack
}
```

### Frontend
```javascript
function hasAccess(userTrack, requiredTrack) {
    return userTrack >= requiredTrack;
}

function isFeatureEnabled(featureName, userTrack) {
    const feature = FEATURE_FLAGS[featureName];
    if (!feature) return false;
    return hasAccess(userTrack, feature.track);
}
```

## Feature Flag API Endpoint

### GET /api/v1/features
Get available features for current user.

```json
{
  "track": 2,
