Support

Answers to common questions and 24/7 support regardless of subscription.

Questions? Answers.

What is Polygon and what are common dApp use cases?

Polygon is an EVM-compatible sidechain secured by proof-of-stake validators. It offers low fees and fast block times, making it popular for DeFi apps, NFT marketplaces, gaming, and social dApps.

Do Polygon RPCs support WebSockets for subscriptions?

Yes. Polygon public RPCs and most dedicated providers support WebSocket endpoints, enabling subscriptions such as eth_subscribe for logs, new blocks, or pending transactions.

How to estimate gas and handle EIP-1559 fees on Polygon?

Use the 1inch Gas Price API.

How to manually add Polygon to your wallet?

Use the following settings:

Mainnet:
Network name: Polygon Mainnet
RPC: https://polygon-rpc.com (plus other load-balanced endpoints)
Chain ID: 137
Symbol: MATIC
Explorer: https://polygonscan.com

What rate limits apply for Polygon endpoints?

Public RPCs are shared and rate-limited (exact thresholds vary). To avoid throttling with high-volume apps, use the 1inch Web3 RPC API.
