Warning
This SDK is in early stages of development and different crates may have different levels of conformance and testing rigour. The completeness of one crate does not imply the completeness of others.
As with any alternate implementation, unintended deviations from the reference implementation (i.e. Dash Core) are possible and must be accounted for as a risk when building on this SDK. If requirements demand strict conformance guarantees, it is recommended to interface with Dash Core through RPC, REST or ZMQ instead.
base-sdk is a parsing and stateless verification SDK for Dash's layer 1 blockchain.
| Crate | Description | CI (develop) | Coverage |
|---|---|---|---|
| dash-num | Hash blobs, 256-bit arithmetic, compact target encoding |  |  |
| dash-p2p-core | P2P message types and wire format |  |  |
| dash-params | Chain parameters for mainnet, testnet3, and regtest |  |  |
| dash-pkc | BLS (legacy + IETF) and secp256k1 operations |  |  |
| dash-pow | Proof of work scheme |  |  |
| dash-primitives | Blocks, transactions, payloads, governance objects |  |  |
| dash-script | Script opcodes, classification, and address derivation |  |  |
| dash-types | Shared byte and integer newtypes, serde helpers |  |  |

All crates support these standard features:
| Feature | Description | Crates |
|---|---|---|
| (baseline) | no_std + alloc, always available | All |
std | Enable standard library support | All |
serde | Enable serde serialization (where applicable) | num, p2p-core, pkc, primitives, script, types |
full | Enables all non-conflicting features | All |
Specific crates define additional features:
| Feature | Description | Crates |
|---|---|---|
aes_hw | Enable hardware-accelerated AES on supported platforms | pow |
bls | Enable standard and legacy BLS support | pkc |
codec | Enable Bitcoin-compatible wire support | types, pkc |
ecdsa | Enable secp256k1 support | pkc |
simd | Use SIMD backends (requires nightly) | pow |
