agent-substrate / substrate

Agent Substrate: the core system

QuipNetwork / quip-validator

A rust implementation of the Quip Protocol forked from Substrate

paritytech / polkadot-sdk

The Parity Polkadot Blockchain SDK

polkadot-js / apps

Basic Polkadot/Substrate UI for interacting with a Polkadot and Substrate node. This is the main user-facing application, allowing access to all features available on Substrate chains.

hyperledger-solang / solang

Solidity Compiler for Solana, Polkadot and Stellar

subsquid / squid-sdk

TypeScript ETL toolkit for indexing Ethereum, Solana, and Substrate data, sourced from SQD Network.

polkadot-js / api

Promise and RxJS APIs around Polkadot and Substrate based chains via RPC calls. It is dynamically generated based on what the Substrate runtime provides in terms of metadata.

polkadot-js / extension

Simple browser extension for managing Polkadot and Substrate network accounts in a browser. Allows the signing of extrinsics using these accounts. Also provides a simple interface for compliant extensions for dapps.

moonbeam-foundation / moonbeam

An Ethereum-compatible smart contract parachain on Polkadot

AstarNetwork / Astar

The dApp hub for blockchains of the future

novasamatech / parity-signer

Air-gapped crypto wallet.

AbdelStark / madara

Modular stack to build Starknet based scaling engines written in Rust

arcships / rutis

A plugin runtime for software that iterates on itself — the substrate where agents write, swap and hot-reload their own plugins in Rust, TypeScript, Python and Go, across processes and machines.

agent-substrate / env

An agentic environment abstraction for Agent Substrate

ai-on-gke / substrate-gke

Substrate customizations on GKE

Dicklesworthstone / franken_drone_geometry_reconstruction

Agent-native, evidence-grade operating substrate for turning owner-authorized drone video into metrically honest semantic digital twins

AreevAI / areev

Self-improving agents, governed. Areev is the substrate for adaptive agents — agents that get better from their own history, under human authority, in steps you can inspect, undo, and re-measure.

agent-substrate / always-on-agent

Run always-on messaging agents on Agent Substrate. A multi-tenant gateway holds the channel connections while each conversation runs as a suspendable actor, so presence stays warm and cognition suspends to reclaim compute. Reference implementation built on OpenClaw.
