Overview
Polkadot Agent Kit is a modular, open-source toolkit designed to simplify the development of agent-based applications and bots for the Polkadot ecosystem. It provides reusable components, utilities, and patterns for interacting with Polkadot and Parachain networks, supporting both core blockchain operations and higher-level agent logic.
Purposes
- Empower developers to build intelligent, automated agents and bots that interact with the Polkadot ecosystem.
- Abstract away complexity of multi-chain operations, transaction management, and agent orchestration.
- Lower the barrier for developers to build on Polkadot and foster a robust ecosystem of agent-based applications.
Key Features
Substrate's Light Client Connection
Connects to Polkadot, Kusama, and parachains via the Smoldot Light Client for decentralized, trustless network access without centralized RPCs.
Wallet Management
Provides a unified interface for managing multiple Polkadot-compatible wallets, including Sr25519 and Ed25519 key types.
Cross-Chain Transactions
Facilitates token transfers and operations via XCM (Cross-Consensus Messaging) between Relay Chain, Asset Hub, and Parachains.

System Overview
The Polkadot Agent Kit follows a layered architecture with clear separation of concerns. The system is organized as a monorepo containing four core packages and supporting infrastructure.
