An Ethereum-compatible smart contract parachain on Polkadot

Hyperbridge is a hyperscalable coprocessor for verifiable, cross-chain interoperability

Picasso Kusama and Composable Polkadot parachains

A decentralized lending & staking protocol built on top of the Polkadot ecosystem.

OAK(Onchain Autonomous Framework) is a unique blockchain built on Substrate framework with event-driven smart contract VM, autonomous transactions, and on-chain scheduler.

KILT blockchain node

Parity Substrate(-based) chains usage and development support

A trustless, cross-chain bridging protocol.

SORA is a new economic system aimed at creating a supranational, world economic system with built-in tools for decentralized finance (DeFi). The SORA network implements a new way of parachain architecture on Polkadot and Kusama network, with the capability to bridge external blockchains (like Ethereum) to the Polkadot ecosystem.

Frequency: A Polkadot Parachain

DataHighway Node. A blockchain being built with Substrate to become a parachain on the Polkadot network. Planned features include a decentralized LPWAN roaming hub for LoRaWAN IoT devices and network operator roaming agreements, participative mining, an inter-chain data market, and DAO governance. http://www.datahighway.com

Fork your substrate-based blockchain state and run all kinds of simulation tests on the runtime.

NeuroWeb Network is a decentralized Artificial Intelligence blockchain designed to incentivise knowledge creation, connectivity and sharing through Knowledge Mining.

Polkaholic - Substrate Chain Block Explorer for Polkadot/Kusama Chains and Parachains

The Subsocial parachain, built with the Substrate framework, provides the blockspace and social primitives needed to build a decentralized social graph.

The Ajuna Node for Kusama and Polkadot

SORA is a new economic system aimed at creating a supranational, world economic system with built-in tools for decentralized finance (DeFi). The SORA network implements a new way of parachain architecture on Polkadot and Kusama network, with the capability to bridge external blockchains (like Ethereum) to the Polkadot ecosystem.

DAO as a service parachain for Polkadot. Built with Parity Substrate. Supports various pluggable voting systems.
