Question 1

Polygon Mainnet RPC: Chain Settings, Endpoint, and Connection Checks

Accepted Answer

Polygon Mainnet is the proof-of-stake, EVM-compatible chain identified by chain ID 137. If you searched for "polygon mainnet," you most likely need to connect a wallet, a dApp, or a backend service to it and want the correct chain settings and a working RPC endpoint without guessing.

This page gives you the chain settings first, then a public OnFinality endpoint you can test immediately, then the checks that separate a quick demo from a production-ready connection. It also explains when a public endpoint is enough and when a dedicated node or managed RPC plan makes more sense.

Polygon Mainnet is not the same as Polygon Amoy, the testnet. Keep the two separate in your config: the mainnet chain ID is 137, while Amoy uses 80002. Mixing them up is one of the most common reasons a deployment looks connected but never confirms a transaction.

Question 2

Mainnet Faucet: What It Is and When You Actually Need One

Accepted Answer

A mainnet faucet is a service that sends small amounts of real, mainnet tokens to a wallet address so you can pay gas or test a transaction on a production network. Unlike testnet faucets, which dispense valueless test tokens, mainnet faucets distribute assets that have market value, so they are rate-limited, captcha-protected, and usually capped at tiny amounts.

Developers typically look for a mainnet faucet when they need a few cents of native gas to deploy a contract, move a token, or verify a wallet flow on a live chain. The tradeoff is that mainnet faucets are scarce and heavily abused, so most teams treat them as a last resort rather than a primary funding path.

This page explains what mainnet faucets actually dispense, how to tell whether you need one or a testnet faucet, and how to configure your RPC connection so the tokens you receive are usable. If you are building on a chain that OnFinality supports, you can pair a faucet drip with a reliable RPC endpoint from the [supported RPC networks](/networks) list.

Question 3

When did peaq mainnet launch, and what does it mean for your 2025 build?

Accepted Answer

peaq's mainnet went live in 2024, moving the DePIN-focused Layer 1 from testnet experiments to a production network where machines, vehicles, and IoT devices can register identities and settle value on-chain. If you are building on peaq now, the launch date matters less than the operational question it raises: which RPC endpoint and node setup will keep your DePIN app responsive as device traffic grows.

This page covers the launch timeline, the Agung testnet relationship, the chain settings you need to connect, and how to decide between a public RPC endpoint and dedicated node infrastructure for production workloads.

Question 4

What is peaq mainnet and how do you connect to it?

Accepted Answer

peaq mainnet is the production Layer 1 blockchain for the DePIN (Decentralized Physical Infrastructure Networks) economy, designed to support real-world devices and machine workloads. This article explains what peaq mainnet is, its key features, and how to connect your applications using RPC endpoints, chain settings, and practical examples.
