# Token Design and Interoperability

Details are provisional and may be updated during development.

Arichain's token system provides native token bridge functionality through a unified registry.

#### Unified Token Architecture

**The Multi-VM Token Challenge:**\
Traditional multi-chain systems require external bridges that create:

* **Security Vulnerabilities**: Third-party bridge operators can be compromised
* **Liquidity Fragmentation**: Same asset exists as different tokens on different chains
* **User Experience Friction**: Complex bridging processes and waiting times
* **Economic Inefficiency**: Multiple token supplies and price discrepancies

**Arichain's Solution:**\
A single, protocol-level native token registry that maintains canonical state across all VMs:

**Native Token Lifecycle Management:**

1. **Registration**: Native token (ARI) metadata recorded in global registry
2. **Multi-VM Deployment**: Native token representation deployed to all VMs automatically
3. **Supply Synchronization**: Real-time native token balance updates across all VM instances
4. **Multi-VM Transfers**: Atomic native token operations without external dependencies
5. **Audit Trail**: Complete native token transaction history across all environments

#### Global Native Token Registry

**Registry Architecture:**

```
Global Native Token Registry:
├── Native Token Metadata Store
│   ├── Token ID (ARI)
│   ├── Name & Symbol
│   ├── Decimals & Total Supply
│   ├── Supported VMs []
│   └── Creation Block Height
├── VM Instance Tracker
│   ├── EVM Native Representation
│   ├── SVM Native Representation
│   ├── Active Supply Per VM
│   └── Transfer Events Log
└── Native Token State Proofs
    ├── Merkle Proofs for Supply
    ├── Transfer Validation Proofs
    └── Integrity Check Results
```
