Here, we provide a list of tools available for your development needs. They are sorted by context. If you're actively maintaining a tool that might be useful to other Polkadot, Kusama or Substrate developers, feel free to .
Please see the page.
- Polkadot dashboard block explorer. Supports dozens of other networks, including Kusama, Westend, and other remote or local endpoints.
- Blockchain explorer for Polkadot, Kusama, and other related chains. .
- Blockchain explorer for Substrate chains. .
- Polkadot & Kusama Blockchain explorer.
- Network information including what nodes are running the chain, what software versions they are running, sync status, and location.
- Polkadot network monitoring and reporting using Matrix (Riot / Element) chat. Users may create custom bot plugins. .
- A Telegram bot for monitoring on-chain events of Substrate chains.
- Polkadot network statistics (includes Kusama). Shows network information and staking details from validators and intentions. .
- A node monitoring and alert server for validators.
- A CLI tool and JS library to monitor on chain states and events.
WebAssembly related tools and projects.
It is designed for high-performance, copy-free encoding and decoding of data in resource-constrained execution contexts, such as the Substrate runtime. It is not self-describing in any way and assumes the decoding context has all type knowledge about the encoded data.
It is used in almost all communication to/from Substrate nodes, so implementations in different languages exist:
The following tools help you extract and structure data from a Substrate node.
- The original Rust implementation of the Polkadot Host.
- A C++ Polkadot implementation of the Polkadot Host developed by .
- A Go implementation of the Polkadot Host developed by .
- Helper functions for offline transaction generation.
- Blockchain development platform written in Rust. The Rust version of the Polkadot Host is being built with Substrate.
- Comprehensive documentation and tutorials for building a blockchain using Substrate.
.
- A collection of debug tools and libraries around substrate chains. Includes tools to calculate NPoS elections offline, disk usage monitoring, test templates against chain state and other pallet-specific helper.
- A tool for easy changing of Polkadot or Substrate dependency versions.
- A tool to easily launch custom local parachain-enabled Polkadot versions.
- A Truffle-inspired local development environment for Substrate.
- Copies the state of an existing chain into your local version and lets you further experiment on it.
- A tool for verifying runtime versions against on-chain proposal hashes.
- A tool to spam your node with transactions for the sake of benchmarking.
- A set of JavaScript utilities making life with Substrate a little easier.
- A tool to benchmark Substrate by flooding it with requests.
- VueJS-based starter kit for custom user interfaces for Substrate chains. .
- Repository of the UI.
- ReactJS-based starter UI for custom user interfaces for Substrate chains.
- Key management in a Chrome extension.
Polkadot-JS Common provides various utility functions that are used across all projects in the @polkadot namespace and is split into a number of internal utility packages. The documentation and usage instructions are provided at .
This allows you to create and load accounts in JavaScript. It is helpful for creating wallets or any application that will require the user to write to chain. .
Utility functions like checking if a string is hex-encoded.
Useful cryptographic utilities for developing with Polkadot.
Command line interface for the polkadot API. .
