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.
