Welcome to Polygon

Polygon is a scaling solution for public blockchain networks. Polygon PoS chain supports all the existing Ethereum tooling along with faster and cheaper transactions.

What is a Blockchain?

Blockchain is a shared, immutable ledger for recording transactions, tracking assets and building trust. Head over to Blockchain Basics section to read more.

What is a Sidechain?

Think of a Sidechain as a clone of a parent blockchain, supporting transfer of assets to and from the main chain. It is simply an alternate to parent chain that creates a new blockchain with its own mechanism of creating blocks (consensus mechanism). Connecting a sidechain to a parent chain involves setting up a method of moving assets between the chains.

Types of Interaction on Polygon

Query the Blockchain

Most blockchain interactions involve reading its state.

Alchemy offers a reference guide on how to make basic requests to the blockchain. Check out their guide on how to query Polygon.

Deploy Smart Contracts


Configure the Web3 RPC-URL to "", everything else remains the same.

Validator and delegator roles

On the Polygon Network, you can be a validator or a delegator. See:


If your goal is to become a validator, it is essential that you understand the Polygon architecture.

See Polygon Architecture.
