This library provides a clean wrapper around all the methods exposed by a Polkadot/Substrate network client and defines all the types exposed by a node, this API provides developers the ability to query a node and interact with the Polkadot or Substrate chains using Dart.
This library is funded by Web3 Foundation via their Open Grants Program
This repo is a monorepo for polkadart and related packages.
| Packages ____________________ |
Description ___________ |
|---|---|
 |
The core package that provides tools to connect and interact with the Polkadot or Substrate chains. It abstracts the complexities of the network protocols and offers straightforward APIs. |
 |
A command-line interface tool that generates dart language types and corresponding definitions by interpreting the chain's metadata. |
 |
Manages keys and addresses for Polkadot/Substrate accounts. Contains cryptographic functions related to creating keys, signing transactions, and managing user identities on the blockchain. |
 |
SCALE (Simple Concatenated Aggregate Little-Endian) is a codec used by Substrate to efficiently encode and decode data. Contains a dart implementation of this codec. |
 |
Implementation of the SECP256k1 elliptic curve used in the ECDSA (Elliptic Curve Digital Signature Algorithm) for cryptographic operations, which is widely used in various blockchain platforms. |
 |
Implementation of Schnorrkel-based signature scheme used in Substrate. Contains functionalities related to this scheme, such as key generation and signing. |
 |
SS58 is a cryptocurrency address format used by Substrate. This package includes utilities to encode and decode these addresses. |
 |
BIP39 (Bitcoin Improvement Proposal 39) pertains to the generation of mnemonic phrases for cryptographic keys. Creates human-readable phrases that map to the keys used on Substrate-based chains. |
 |
Provides the necessary tools to decode the metadata provided by a Substrate blockchain node. And can be used to easily decode constants, extrinsics, events, and other data written in the chain. |
You can run all tests from the library by running docker compose up;
Or if you have Melos installed globally you can run melos test.
