Set Up Your Environment

Before you begin deploying smart contracts on Metis, you need to ensure that your development environment is properly configured.

1. Install MetaMask and Connect to Metis

MetaMask is the most commonly used wallet to interact with dApps on networks like Metis. Here’s how to set it up:

Install Metamask

• Download and install the MetaMask extension for your browser.

• Create a new wallet or import an existing wallet using your seed phrase.

Add Metis Network to MetaMask:

To connect to the Metis Andromeda (Mainnet) or Sepolia (Testnet) network, you’ll need to manually add it to MetaMask.

Values	Andromeda (Mainnet)	Sepolia (Testnet)
RPC URL	https://andromeda.metis.io/?owner=1088	https://sepolia.metisdevops.link
Chain ID	1088	59902
Currency Symbol	METIS	sMETIS
Block Explorer URL	Andromeda Explorer	Sepolia Explorer

MetaMask will now be connected to the Metis network.

2. Get Testnet Tokens (Sepolia)

If you’re developing on the Metis Sepolia Testnet, you’ll need sMetis tokens to test your transactions and smart contracts.

1. Visit the Metis Faucet:

   • You can get free testnet tokens by visiting the official Metis Sepolia Testnet Faucet
