Polygon RPC
Polygon Overview
Polygon PoS is an EVM-compatible, proof-of-stake sidechain for Ethereum . The Polygon Proof-of-Stake (PoS) network is designed to address scalability challenges within the Ethereum ecosystem and consists of a consensus layer called Heimdall and execution layer called Bor . The network architecture includes:
- Heimdall Layer: A set of proof-of-stake Heimdall nodes running in parallel to the Ethereum mainnet, monitoring the set of staking contracts deployed on the Ethereum mainnet
- Bor Layer: Bor is Polygon PoS's block producer — the entity responsible for aggregating transactions into blocks
- Ethereum Integration: Core contracts on the Ethereum mainnet incorporate a key feature for security and functionality: the exit queue
- Checkpoint System: A checkpoint of the validated transactions is created and submitted to the core contracts on the Ethereum mainnet every 30 minutes or so
Public checkpoint nodes serve as validators in the Polygon PoS architecture and ensure security through periodic state commitments to Ethereum.
Interacting with Polygon's APIs
該 erigon_* 以及 trace_* method namespaces will be deprecated on Amoy Testnet (July 1, 2026) 以及 Mainnet (July 15, 2026) as Quicknode migrates from Erigon to Bor. Use the debug_trace* namespace and eth_getLogs as alternatives. See Polygon Labs' Erigon sunset notice for details.
All your favorite Ethereum tools (Foundry, Remix, Ethers.js) work seamlessly on Polygon, with the same familiar UX . The JSON-RPC API extends standard Ethereum methods with Polygon-specific functionality for accessing the sidechain's unique features.
You don't have to worry about the underlying architecture while moving or deploying your dApps to the Polygon PoS network as long as it is EVM-compatible . However, developers should understand Polygon's checkpoint system and dual-layer architecture when building applications that require cross-chain functionality or validator interactions.
Make Polygon API Calls
The quickest way to start building on Polygon is to create a Quicknode endpoint and send your first JSON-RPC request.
Quicknode provides managed Polygon endpoints, giving you immediate access to Polygon Mainnet and Mumbai Testnet without the overhead of running your own infrastructure. These endpoints offer:
- High reliability – globally distributed infrastructure designed to minimize downtime
- Enhanced performance – optimized latency and request handling for production-grade apps
- Integrated ecosystem – additional functionality through specialized APIs and Quicknode add-ons
Visit the QuickStart page to create your endpoint and send your first request.
