* **Batch Operations**: Efficient handling of multiple token operations
* **IPFS Integration**: Decentralized storage for token logos and images

#### System Architecture

The Token Registry consists of several interconnected smart contracts:

1. **TokenRegistry**: The main contract handling token registration and status management
2. **TokenMetadata**: Manages additional token information and metadata fields
3. **TokenEdits**: Handles the proposal and approval of token information updates
4. **Helper**: Provides utility functions for batch operations
5. **TokentrollerV1**: Manages governance and access control
