Polkadot RPC
폴카닷 개요
Polkadot operates as a Layer 0 relay chain that provides shared security and cross-chain communication for independent blockchains called parachains. Rather than each blockchain maintaining its own validator set, Polkadot's relay chain validators secure all connected parachains simultaneously. Interoperability occurs through Cross-Consensus Messaging (XCM), enabling parachains to communicate while maintaining sovereignty.
Polkadot provides the Substrate framework for building custom blockchains. Developers write parachain runtime logic in Rust using Substrate's modular architecture. The platform exposes multiple API interfaces—the Polkadot JSON-RPC API for relay chain operations, Substrate API Sidecar for RESTful queries, and Asset Hub API for the system parachain that handles token transfers and NFT operations.
Interacting with Polkadot's APIs
Polkadot supports JSON-RPC API methods for querying blockchain state and submitting transactions, Substrate API Sidecar for RESTful access to historical data and account information, and Asset Hub JSON-RPC API for parachain interactions. Developers can use Polkadot.js libraries or standard HTTP/WebSocket clients to communicate with Polkadot nodes.
The Quicknode Polkadot documentation is continuously evolving as the network undergoes upgrades and changes, so we highly recommend cross-referencing with the official Polkadot documentation for the latest updates and features.
Make Polkadot API Calls
The quickest way to start building on Polkadot is to create a Quicknode endpoint and send your first JSON-RPC request.
Quicknode provides managed Polkadot endpoints, giving you immediate access to Polkadot Mainnet without the overhead of running infrastructure. These endpoints offer:
- 높은 신뢰성 – 가동 중단 시간을 최소화하도록 설계된 전 세계에 분산된 인프라
- 향상된 성능 – 프로덕션급 앱을 위한 지연 시간 및 요청 처리 최적화
- 통합 생태계 – Quicknode 마켓플레이스의 전용 API(애드온) 및 Streams와 같은 제품을 통한 추가 기능

지원되는 네트워크
Quicknode provides access to the following Polkadot networks:
Quicknode's Polkadot endpoint provides access to both AssetHub and Relaychain networks through a unified interface.
AssetHub handles most current operations including token transfers, NFT management, and parachain state queries. REST API calls target AssetHub by default:
# AssetHub (default)
curl 'https://your-endpoint.pro/blocks/head'
Polkadot Relaychain provides access to relay chain data, validator information, and historical records. Prefix REST API calls with /rc to access the relaychain:
# Polkadot Relaychain
curl 'https://your-endpoint.pro/rc/blocks/head'
JSON-RPC methods operate without network prefixes and maintain standard compatibility across both networks.
