# Supported Chains

## Offsetdata Chrome Extension

The Offsetdata Chrome Extension supports several public blockchains, primarily on their respective testnets. Here are the currently supported chains:

**Polygon (MATIC):** The extension allows you to activate and manage web3 data on the Polygon testnet. Polygon is a scaling solution for Ethereum, offering fast and low-cost transactions.

**Base Chain:** The extension supports the Coinbase Base Chain. However, please note that the extension supports a testnet version of the base chain.

**Camino Network:** The extension enables you to activate and work with web3 data on the Camino testnet (Columbus).

**Binance Smart Chain (BSC):** The extension supports BSC's testnet, allowing you to manage web3 data on the Binance Smart Chain. BSC is a popular blockchain platform for decentralized applications (dApps) and token transfers.

**ZK-EVM:** The extension provides support for the Polygon ZK-EVM testnet. ZK-EVM combines zero-knowledge proofs with Ethereum's virtual machine (EVM), enabling scalable and privacy-preserving smart contracts.

> Please note that the Beta version of the extension focuses on testnet environments rather than the mainnet versions of these blockchains.
