Polygon RPC Endpoints, API & Dedicated Nodes

Build on Polygon with OnFinality RPC endpoints and dedicated node options for apps that need reliable access to Polygon PoS. Polygon is an EVM-compatible network, so teams can use familiar Ethereum tooling while benefiting from lower-cost transactions and faster app workflows.

Polygon RPC use cases

Polygon RPC endpoints let applications read balances, call contracts, submit transactions, query logs, and monitor receipts. The endpoint becomes part of the user experience for wallets, games, DeFi products, NFT tools, trading bots, analytics jobs, and backend services.

Common workloads include:

• User-facing dApps that need responsive reads and transaction status.
• Backend jobs that query logs, receipts, and contract state.
• Analytics or compliance workflows that need archive access.
• Debugging workflows that use trace data where supported.

OnFinality Polygon RPC features

• Network: Polygon Mainnet, Chain ID 137
• Protocol: EVM JSON-RPC
• Transport: HTTP and WebSocket
• Advanced access: Archive and trace support available
• Dedicated nodes: Dedicated Polygon node options for production workloads

What to test first

Start with eth_blockNumber, then test eth_call, eth_getLogs, transaction submission, WebSocket subscriptions, and the exact retry behavior your app uses under load.

Polygon mainnet and Amoy testing

Use Polygon Amoy for staging contract deployments and wallet flows before moving traffic to mainnet. Keep your testnet and mainnet endpoint strategy close enough that release checks catch real integration problems.

Next steps:

• Create or manage RPC endpoints
• Compare RPC pricing
• Read the Polygon Amoy RPC guide
• Open Polygon Amoy RPC

Polygon RPC and developer resources

Polygon teams usually arrive with an EVM app, wallet, game, or analytics workflow and need to know whether the endpoint supports their read, debug, and production planning needs.

Best fit: mainnet production workflows for dApps, wallets, DeFi, and backend services.

What builders usually check first:

• Read current chain state for apps, dashboards, wallets, and backend services.
• Submit transactions and monitor confirmations from Ethereum-compatible tools.
• Query logs, receipts, and historical state when indexers or analytics pipelines need more than the latest block.
• Debug contract behaviour with trace data where the network supports it.

Supported capability notes:

• Authenticated Polygon RPC/API access for dApps, wallets, DeFi, and backend services.
• HTTP and WebSocket support for app, backend, and integration workflows.
• Archive access for historical state, analytics, or compliance-style queries.
• Trace support for debugging transactions and deeper execution analysis.
• Dedicated node options when shared RPC no longer fits traffic or isolation needs.

Decision notes:

• Environment: mainnet. Protocol family: EVM JSON-RPC.
• HTTP and WebSocket support is listed for supported app and backend workflows.
• Archive support is available for historical state or older chain-data queries.
• Trace support is available for transaction debugging and execution analysis.
• Dedicated node options are available when the workload needs isolated resources or more operational control.

A quick connection check usually starts with eth_blockNumber, then moves into the exact methods your wallet, dashboard, bot, indexer, or backend service needs.

Planning the next step:

• Shared RPC is usually enough for early integration, prototypes, and moderate app traffic.
• Consider dedicated nodes when traffic becomes sustained, workloads are latency-sensitive, or isolation and monitoring become operational requirements.

• Create or manage RPC endpoints
• Review RPC pricing
