Zombienet
Project Links
Description
Zombienet lets developers define local Polkadot and Substrate network topologies in TOML or JSON, launch their nodes through native, Podman, or Kubernetes providers, and run assertions against on-chain storage, metrics, logs, events, and custom scripts. The project distributes executable releases and remains under active development.Category: Developer Tooling
Parity SCALE Codec
Project Links
Description
Parity SCALE Codec implements SCALE (Simple Concatenated Aggregate Little-Endian) serialization and deserialization for Rust. It is designed for Substrate types and resource-constrained environments such as blockchain runtimes, and provides encoding, decoding, compact encoding, and derive functionality.Category: Developer Tooling
Subxt
Project Links
Description
Subxt provides statically typed and dynamic interfaces for submitting extrinsics, accessing on-chain data and runtime APIs at specific blocks, subscribing to new blocks, and interacting trustlessly through a built-in light client. It supports WebAssembly and browser use, FFI integrations, and offline workflows, and is used by Polkadot ecosystem tools, relayers, and ink! smart-contract testing.Category: Developer Tooling
Substrate Connect
Project Links
Description
Substrate Connect is a browser-based light-client project for Substrate-based blockchains. It provides packages including @substrate/connect, discovery protocol components, and light-client extension helpers, plus example implementations for dApps, wallets, and browser extensions in the Polkadot ecosystem.Category: Developer Tooling
Product SDK
Project Links
Description
Product SDK provides a unified app entry point plus leaf packages for typed chain access, transaction submission, signing, key derivation, contract interactions, cloud storage, statement-store messaging, cryptography, and developer utilities.Category: Developer Tooling
Polkadot SDK
Project Links
Description
Polkadot SDK is an open-source Rust blockchain framework and monorepository. It consolidates the former Substrate, Polkadot, and Cumulus repositories and provides components, templates, documentation, and tooling for building Polkadot and parachains.Category: Developer Tooling
JAM
Project Links
Description
JAM is a protocol combining elements of Polkadot and Ethereum. It provides a permissionless service environment, resource-priced execution, and secure parallelized computation across a validator network. Official documentation describes it as a prospective chain intended to succeed the Polkadot relay chain and support rollup-oriented computation.Category: L1
Substrate API Sidecar
Project Links
Description
Substrate API Sidecar is a Node.js/TypeScript service and npm CLI package that connects to Substrate-based nodes and exposes REST endpoints for account data, blocks, runtime metadata, transactions, staking, and related blockchain operations. Parity has deprecated it in favor of the separate Rust-based Polkadot REST API; its final feature release will receive only critical-security backports, if any.Category: Developer Tooling
Polkadot Bulletin Chain
Project Links
Description
Polkadot Bulletin Chain is a Parity Technologies reference implementation of a storage parachain for the Polkadot ecosystem. It stores arbitrary data under content identifiers, supports IPFS/Bitswap retrieval, authorization-based writes, configurable retention and renewal, cross-chain integration with People Chain, Rust and TypeScript SDKs, and a browser console. Official materials describe it as experimental and actively under development, with current deployments on test networks rather than Polkadot mainnet.Category: Decentralized File Storage
Individuality SDK
Project Links
Description
Individuality SDK is a standalone Parity Technologies project providing an in-development People-chain upgrade and integration pallets for interoperability with chains such as Asset Hub. The code is experimental, unaudited, actively developed, and explicitly separate from the official People chain.Category: Developer Tooling
Substrate
Project Links
Description
Substrate supplies modular components for blockchain runtimes and networks, including networking, consensus and runtime development. Its former standalone repository was consolidated into the Polkadot SDK; the maintained Substrate code remains part of that SDK.Category: Developer Tooling
