bytes operations +- Core version activation queries + +## Usage + +### Building + +```bash +cargo build --release +``` + +### Generating Bindings + +To generate bindings for your target language: + +```bash +cargo run --bin uniffi-bindgen generate src/dash_network.udl --language swift +cargo run --bin uniffi-bindgen generate src/dash_network.udl --language python +cargo run --bin uniffi-bindgen generate src/dash_network.udl --language kotlin +``` + +### Example Usage (Swift) + +```swift +// Initialize the library +dashNetworkFfiInitialize() + +// Create a network info object +let networkInfo = NetworkInfo(network: .dash) + +// Get magic bytes +let magic = networkInfo.magic() +print("Dash network magic: \(String(format: "0x%08X", magic))") + +// Check if core v20 is active +if networkInfo.isCoreV20Active(blockHeight: 2000000) { + print("Core v20 is active!") +} + +// Create from magic bytes +do { + let network = try NetworkInfo.fromMagic(magic: 0xBD6B0CBF) + print("Network: \(network.toString())") +} catch { + print("Invalid magic bytes") +} +``` + +### Example Usage (Python) + +```python +import dash_network_ffi + +# Initialize the library +dash_network_ffi.initialize() + +# Create a network info object +network_info = dash_network_ffi.NetworkInfo(dash_network_ffi.Network.DASH) + +# Get magic bytes +magic = network_info.magic() +print(f"Dash network magic: 0x{magic:08X}") + +# Check if core v20 is active +if network_info.is_core_v20_active(2000000): + print("Core v20 is active!") + +# Create from magic bytes +try: + network = dash_network_ffi.NetworkInfo.from_magic(0xBD6B0CBF) + print(f"Network: {network.to_string()}") +except dash_network_ffi.NetworkError.InvalidMagic: + print("Invalid magic bytes") +``` + +## API + +### Network Enum + +- `Dash` - Dash mainnet +- `Testnet` - Dash testnet +- `Devnet` - Dash devnet +- `Regtest` - Regression test network + +### NetworkInfo Class + +#### Constructors +- `new(network: Network)` - Create from a Network enum value +- `from_magic(magic: u32)` - Create from magic bytes (throws NetworkError) + +#### Methods +- `magic() -> u32` - Get the network's magic bytes +- `to_string() -> String` - Get the network name as a string +- `is_core_v20_active(block_height: u32) -> bool` - Check if core v20 is active at height +- `core_v20_activation_height() -> u32` - Get the activation height for core v20 + +### NetworkError Enum + +- `InvalidMagic` - Invalid magic bytes provided +- `InvalidNetwork` - Invalid network specified + +## License + +This project is licensed

Issues Fixed + +### 1. **dash/src/consensus/params.rs** +- **Issue**: Catch-all arm silently mapped unknown networks to "regtest-like" params +- **Fix**: Replaced with explicit panic for unknown networks +```rust +// Before: _ => Params { ... regtest-like params ... } +// After: other => panic!("Unsupported network variant: {other:?}") +``` + +### 2. **dash/src/blockdata/constants.rs** +- **Issue**: Unknown networks silently treated as Regtest for genesis block +- **Fix**: Added explicit unreachable! for unknown networks +```rust +// Before: _ => Block { ... regtest genesis ... } +// After: other => unreachable!("genesis_block(): unsupported network variant {other:?}") +``` + +### 3. **dash/src/address.rs** +- **Issue**: Unknown networks defaulted to testnet prefixes, risking fund loss +- **Fix**: Added unreachable! for all prefix matches +```rust +// Before: _ => PUBKEY_ADDRESS_PREFIX_TEST +// After: other => unreachable!("Unknown network {other:?} – add explicit prefix") +``` + +### 4. **dash/src/sml/llmq_type/network.rs** +- **Issue**: Wildcard arm could mask incorrect LLMQ selection +- **Fix**: Replaced all catch-all arms with unreachable! +```rust +// Before: _ => LLMQType::LlmqtypeTestInstantSend +// After: other => unreachable!("Unsupported network variant {other:?}") +``` + +### 5. **dash-network/src/lib.rs** +- **Issue**: TODO placeholder returned misleading value for core_v20_activation_height +- **Fix**: Added explicit values for all networks with panic for unknown +```rust +Network::Devnet => 1, // v20 active from genesis on devnet +Network::Regtest => 1, // v20 active from genesis on regtest +#[allow(unreachable_patterns)] +other => panic!("Unknown activation height for network {:?}", other) +``` + +### 6. **dash-network-ffi/src/lib.rs** +- **Issue**: Unknown variants silently mapped to Testnet +- **Fix**: Added panic for unknown network variants +```rust +// Before: _ => Network::Testnet, // Default for unknown networks +// After: unknown => panic!("Unhandled Network variant {:?}", unknown) +``` + +### 7. **key-wallet/src/address.rs** +- **Issue**: from_str required network parameter when version byte already identifies it +- **Fix**: Modified to infer network from version byte +```rust +// Before: pub fn from_str(s: &str, network: Network) -> Result +// After: pub fn from_str(s: &str) -> Result +// Infers network from version byte (76=Dash mainnet, 140=testnet, etc.) +``` + +### 8. **key-wallet-ffi/src/lib.rs** +- **Issue 1**: Hard-coded coin-type breaks Testnet/Devnet +- **Fix**: Use network-specific coin types +```rust +let coin_type = match self.network { + Network::Dash => 5, // Dash mainnet + _ => 1, // Testnet/devnet/regtest +}; +``` + +- **Issue 2**: Network enum needs repr(u8) for FFI stability +- **Fix**: Added repr attribute +```rust +#[repr(u8)] +#[derive(Debug, Clone, Copy, PartialEq, Eq)] +pub enum Network { + Dash = 0, + Testnet = 1, + Regtest = 2, + Devnet = 3, +} +``` + +- **Issue 3**: Pattern matching Base58 variant incorrectly +- **Fix**: Changed from tuple variant to unit variant +```rust +// Before: kw::Error::Base58(err) => ... +// After: kw::Error::Base58 => ... +``` + +## Testing Impact + +- All catch-all patterns now explicitly panic or use unreachable!, preventing silent misconfigurations +- Network inference in address parsing maintains backward compatibility while being more correct +- FFI bindings now have stable enum representations +- Coin type derivation now follows BIP44 standards for test networks + +## Migration Notes + +For users of `key_wallet::Address::from_str`: +- The function no longer requires a network parameter +- Network is inferred from the address version byte +- For validation against a specific network, use the returned address's network field + +For FFI users: +- The Network enum now has stable numeric values (0-3) +- Address parsing still accepts a network parameter for validation \ No
