MetaMask is one of the most widely used cryptocurrency wallets, enabling secure access to Web3, DeFi trading, NFTs, and decentralized exchanges like Hyperliquid. It’s available as a browser extension and mobile app, making it easy to connect to decentralized apps. To set up a MetaMask wallet, install the official extension or app from the MetaMask website or your device’s app store. Create a strong password, then back up your Secret Recovery Phrase — this 12-word phrase is your only way to recover your wallet if you lose access, so store it offline and never share it digitally. Once set up, you can receive tokens by copying your wallet’s public address or buy crypto directly through MetaMask’s integrated provider. After funding, connect to Hyperliquid or other DeFi platforms by clicking “Connect Wallet” and approving the transaction within MetaMask. This process is essential before you can trade perpetual futures, provide liquidity, or participate in on-chain DeFi features.
