A Polygon RPC endpoint is a URL that connects an application to a Polygon node. It lets you read balances and smart-contract state, estimate gas, submit signed transactions, and retrieve blocks and transaction receipts through JSON-RPC. Chainstack provides HTTPS and WebSocket endpoints for Polygon PoS.
Create a Chainstack account, deploy a Polygon PoS node on mainnet or Amoy, and copy the HTTPS or WebSocket URL from its access details. The free Developer plan includes 3 million request units per month, 25 requests per second, and one node. No credit card is required.
Yes. Use Polygon RPC to read onchain balances, token approvals, outcome-token transfers, and settlement transactions. Use Polymarket’s APIs for market discovery, order books, and order submission. Polygon RPC complements those APIs; it does not replace the trading API.
Yes. Use eth_subscribe over WebSocket for new blocks, contract logs, and pending transaction notifications. A pending-transaction feed reflects the transactions visible to the node. Full transaction-pool inspection with txpool_content requires a Dedicated Node with the namespace enabled on request.
Use archive access when your application needs smart-contract state or balances at historical blocks, such as portfolio reconstruction, financial reconciliation, analytics, or transaction investigation. Chainstack archive data is available from the Growth plan. A Dedicated Node provides isolated infrastructure for workloads that require their own resources.
Yes. Debug & Trace APIs are available from the Growth plan. Use methods such as debug_traceTransaction and debug_traceCall to inspect execution, investigate reverted calls, and troubleshoot contract interactions. Method availability depends on the node client and configuration.
Yes. Chainstack Self-Hosted supports Polygon PoS mainnet and Amoy deployments using Bor and Heimdall. You provide the infrastructure and an Ethereum layer 1 RPC endpoint for checkpoint tracking. Follow the installation guide and the supported-deployments documentation for current resource requirements.
Use the Chainstack Amoy faucet at https://faucet.chainstack.com/amoy-faucet. It tops up eligible wallets to 0.01 Amoy POL, with a claim available every 24 hours. Amoy POL is testnet currency for gas and testing; it has no monetary value.
Polygon PoS is EVM-compatible. You can connect Chainstack endpoints to ethers.js, viem, web3.py, Hardhat, Foundry, and MetaMask. Use the correct chain ID and endpoint for Polygon mainnet or Amoy.
Polygon PoS exposes an EVM-compatible JSON-RPC API over HTTPS and WebSocket. Mainnet uses chain ID 137; Amoy uses 80002. POL is the native gas token on both networks. Connect ethers.js, viem, web3.py, Hardhat, or Foundry to the corresponding Chainstack endpoint.
Use eth_subscribe for new blocks, contract logs, and pending transaction notifications. The pending feed reflects the node’s view of the public mempool. Transaction-pool inspection methods such as txpool_content require a Dedicated Node with the namespace enabled on request. Historical state queries and Debug & Trace APIs are available from the Growth plan; supported methods depend on the client and node configuration.
For Polymarket integrations, Polygon RPC provides onchain balances, approvals, token transfers, and settlement data. Market discovery, order books, and order submission use Polymarket’s own APIs.
Chainstack Self-Hosted deploys Bor and Heimdall for Polygon PoS mainnet and Amoy. You supply an Ethereum layer 1 RPC endpoint for checkpoint tracking. Use the Chainstack Amoy faucet to obtain testnet POL for development.
