1. What is Metamask?

Before we delve into the specifics of Metamask, let's clarify two fundamental types of cryptocurrency wallets: custodial and non-custodial.

• Custodial Wallets: In a custodial wallet, a third party holds your private keys and assets on your behalf. Think of a traditional bank account; the bank is the custodian of your funds. Examples include centralized exchanges like Binance
• Non-Custodial Wallets: With a non-custodial wallet, you maintain complete control over your private keys and assets. No third party can access your funds without your permission. Metamask is a prime example of a non-custodial wallet.

What is Metamask?

Metamask is a popular non-custodial cryptocurrency wallet that allows users to store and manage a wide range of digital assets across various blockchain networks. Launched in 2016, Metamask has quickly become a staple in the blockchain ecosystem, offering a secure and user-friendly interface
