feat: ✨ Standardize currency system to HAVE token with Wei-based units ( #130 )
...
## Summary
This PR modernizes DataHaven's currency system by standardizing all
three runtimes (mainnet, stagenet, testnet) to use Ethereum-compatible
Wei-based units with HAVE as the native token name.
### Key Changes
#### 🔄 Currency Unit Standardization
- **Migrated from decimal-based to Wei-based system** (18 decimals)
- **Wei units**: WEI → KILOWEI → MEGAWEI → GIGAWEI
- **HAVE units**: MICROHAVE → MILLIHAVE → HAVE → KILOHAVE
- **Zero Existential Deposit**: Enables dust account support with
`insecure_zero_ed` feature
#### 🏷️ Token Naming
- **UNIT → HAVE**: Native token renamed to reflect DataHaven branding
- **Consistent terminology**: All constants, comments, and documentation
updated
- **Supply factors preserved**: Mainnet (100x), Stagenet/Testnet (1x)
#### ⚖️ Block Weights & Gas Configuration
- **Solochain-optimized**: Updated MAX_POV_SIZE and block weight
parameters
- **EVM compatibility**: Fixed GasLimitPovSizeRatio (u32 → u64) and
storage growth ratios
- **Proper fee structure**: Aligned with Ethereum standards
#### 🧪 Test Updates
- **Treasury tests fixed**: Updated to handle zero existential deposit
behavior
- **All tests passing**: Currency references updated across all runtime
tests
- **Storage hub parameters**: Updated to use HAVE token terminology
### Breaking Changes
⚠️ **Currency precision changed from 12 to 18 decimals**
- Applications using currency constants must update to new HAVE-based
naming
- ExistentialDeposit now 0 (was previously enforced minimum balance)
### Runtime Coverage
- ✅ **Mainnet runtime** (supply factor: 100)
- ✅ **Stagenet runtime** (supply factor: 1)
- ✅ **Testnet runtime** (supply factor: 1)
- ✅ **Storage hub parameters** (runtime params updated)
### Technical Details
#### Fee Structure
```rust
pub const TRANSACTION_BYTE_FEE: Balance = 1 * GIGAWEI * SUPPLY_FACTOR;
pub const STORAGE_BYTE_FEE: Balance = 100 * MICROHAVE * SUPPLY_FACTOR;
pub const WEIGHT_FEE: Balance = 50 * KILOWEI * SUPPLY_FACTOR / 4;
```
#### Block Configuration
```rust
pub const MAXIMUM_BLOCK_WEIGHT: Weight = Weight::from_parts(
WEIGHT_REF_TIME_PER_SECOND.saturating_mul(2),
MAX_POV_SIZE as u64,
);
```
## Test Plan
- [x] All runtime builds compile successfully
- [x] All unit tests pass across three runtimes
- [x] Treasury fee handling verified with zero existential deposit
- [x] Storage hub parameter compatibility confirmed
- [x] EVM gas limit calculations validated

## Summary by CodeRabbit
- New Features
- Introduced a unified currency module with HAVE units (18 decimals),
fees, and a deposit helper.
- Adopted dynamic block weight/length configuration (5 MB blocks) and
re-exported gas-to-weight constants.
- Improvements
- Switched all runtimes and pricing parameters from UNIT/NANO_UNIT to
HAVE/GIGAWEI.
- Updated deposits, fees, and rewards to HAVE-based values across
modules (including StorageHub and Snowbridge).
- Made existential deposit runtime-configurable; enabled zero-ED mode on
selected networks.
- Updated metadata hash and token metadata to reference HAVE (symbol
wHAVE, 18 decimals).

feat(operator): ✨ Multi-runtime support ( #38 )
...
Add support for multiple runtimes: `stagenet`, `testnet` & `mainnet`.
- Moved common types to `datahaven-runtime-common` crate.
- Made the node's command & service code generic over different
runtimes. Each runtime has a `dev` & `local` genesis config preset.
- More types / constants can be moved to the `datahaven-runtime-common`
crate ... this will be done in subsequent PRs.
