Step-by-Step Setup Guide

1. Creating a New Wallet

• Choose "Create New Wallet" and set a strong password.

  • Note: This password protects local access—not your private keys.

2. Backup Your Seed Phrase

• Write down the 12/24-word recovery phrase offline.

  • Never store digitally (e.g., screenshots, cloud).

3. Adding Networks

• Default: Ethereum Mainnet. Add others (e.g., BSC, Polygon) via:

  Settings > Networks > Add Network  

Sending Crypto: Key Checks

1. Confirm the blockchain (e.g., ETH on Ethereum, BNB on BSC).
2. Verify the recipient address (double-check characters).
3. Gas fees: Adjust based on network congestion.

Using MetaMask’s Swap Feature

• Swap tab: Exchange tokens directly within MetaMask.
• Aggregator model: Compares rates across DEXs (e.g., Uniswap, SushiSwap).
• Caution: High slippage or fees may apply during volatility.

Avoiding Scams: Critical Rules

1. No DM support: MetaMask will never contact you via email/telegram.
2. Check URLs: Only use https://metamask.io.
3. Limit approvals: Audit contracts via Revoke.cash.
