### `dedot` subpath packages

By default `dedot` package only re-exports primitives from `@dedot/api`, `@dedot/providers`, `@dedot/shape`, giving you enough APIs to connect to the network & making on-chain interactions. It also comes with a few subpath packages giving access to APIs to working with ink! contracts, known-codecs, utility functions...
