## Metamask - Web3 Browser Wallet <a href="#metamask-web3-browser-wallet" id="metamask-web3-browser-wallet"></a>

Metamask is a browser extension that allows you to interact with Ethereum-based decentralized applications (dApps) directly from your browser. It acts as a wallet for storing Ethereum and other ERC-20 tokens. It also provides a way to manage your digital assets and interact with smart contracts.

* **Download:** [Metamask](https://metamask.io/download/)
* **Seed Phrase:** A seed phrase, also known as a recovery phrase or backup phrase, is a set of 12 or 24 words that are used to restore access to your cryptocurrency wallet. It's essential to keep your seed phrase secure and private, as anyone with access to it can control your wallet.
* **Private and Public Key:** In cryptography, a private key is a secret number that allows you to sign transactions and access your cryptocurrency. It should be kept secure and never shared with anyone. A public key is derived from the private key and is used to receive cryptocurrency. It's safe to share your public key, as it's only used for receiving funds.

RPC stands for Remote Procedure Call, and it's a protocol used by Metamask to communicate with Ethereum nodes. By adding Scroll Sepolia RPC to Metamask, you can connect to the Scroll network and interact with its blockchain.

### Faucet for Gas Fees and Bridge ETH to Scroll <a href="#faucet-for-gas-fees-and-bridge-eth-to-scroll" id="faucet-for-gas-fees-and-bridge-eth-to-scroll"></a>

In blockchain networks like Ethereum, gas is used to pay for transactions. A faucet is a service that provides users with a small amount of cryptocurrency for free, usually to cover transaction fees. The bridge allows you to transfer assets between different blockchains, such as from Ethereum to Scroll.
