Option 1: Import via Private Key

1. Open MetaMask and click the account circle in the top right
2. Select "Import Account" from the dropdown menu
3. Choose "Private Key" as the import type
4. Paste your private key (the 0x... string from the CLI output)
5. Click "Import" - your wallet will be added to MetaMask

Option 2: Import via Seed Phrase

1. Open MetaMask and click the account circle in the top right
2. Select "Import using Secret Recovery Phrase"
3. Enter your 12-word mnemonic (the word phrase from the CLI output)
4. Set a password and click "Import"

Import via Seed Phrase (Recommended)

1. Open Brave Wallet (Menu → More Tools → Crypto Wallets)
2. Click "Already have a wallet?"
3. Select "Import wallet"
4. Enter your 12-word mnemonic (the word phrase from the CLI output)
5. Set a password and click "Continue"

Note: Brave Wallet does not support direct private key import. Use the mnemonic seed phrase instead.

⚠️ Important: The generated mnemonic and private keys are displayed in plain text. In a production environment, consider:

• Storing seed phrases and private keys securely
• Using environment variables or secure storage
• Never sharing or committing mnemonics/private keys to version control
• Only import seed phrases you generated yourself
• Never share your mnemonic or private key with anyone
• Consider these test wallets only - don't store significant funds
• Use hardware wallets for production/mainnet funds
• Both the mnemonic and private key give complete control over the wallet
