What is MetaMask Extension®?

As a non-custodial wallet, MetaMask gives you full control of your private keys, ensuring that you and only you have access to your funds. With MetaMask, users can:

• Store ETH and ERC-20 tokens
• Connect to Ethereum-compatible networks (like BNB Chain, Polygon, Arbitrum)
• Swap cryptocurrencies directly
• Interact with dApps, DeFi protocols, and NFT marketplaces like OpenSea
