## 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 ## Files Modified **27 files changed, 728 insertions(+), 342 deletions(-)** - Runtime lib.rs files (currency module definitions) - Cargo.toml files (insecure_zero_ed feature) - Configuration modules (block weights, gas limits) - Test suites (currency constant references) - Storage hub runtime parameters --- 🤖 *Generated with [Claude Code](https://claude.ai/code)* <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## 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). <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Ahmad Kaouk <ahmadkaouk.93@gmail.com>
