The Metamask client is a web browser extension available on Chrome, Firefox, Brave and Edge. It offers a bridge between Ethereum blockchain (and other ERC-20 tokens) and your web browser. It’s the perfect tool to manage your NFTs or interact with DeFi services (Decentalised Finance), smart contracts, and other dApps (Decentralised Applications).

What are custom networks

A custom network is a non-Ethereum network that is EVM ready (Ethereum Virtual Machine). According to the Ethereum documentation, the Ethereum Virtual Machine ready network shares a lot in common with the Ethereum network. Among these similarities, these networks share the same addresses system meaning your addresses will be the same across all networks.

How to add custom networks

Open your web browser and click on the Metamask add-on icon.
