Crypto 101

1. Install a wallet

A browser wallet holds your keys and signs transactions. Install MetaMask from the official site or search for it in your browser's extension store — only install from the store directly, never from a third-party download link. Alternatives that work just as well: Rabby (better phishing protection), Coinbase Wallet, or the built-in Brave Wallet.

During setup you'll be shown a 12-word recovery phrase. Write it on paper and store it somewhere physically safe. Anyone with those words controls the wallet — no legitimate site or support team will ever ask you for it.

2. Switch to Sepolia testnet

Click the network selector at the top of MetaMask and choose Sepolia. If it's not listed, go to Settings → Advanced and enable Show test networks. Sepolia is a free public testnet — ETH here has no market value.

3. Get test ETH

Faucets send free Sepolia ETH on request. Most require a Google or GitHub login to limit abuse. A few tickets cost Ξ0.005 each, so any faucet amount is plenty.

Paste your wallet address (starts with 0x, shown at the top of MetaMask) into the faucet and wait about 30 seconds for it to arrive. If one is rate-limiting you, try another.

4. Connect and play

Open the Quintile Lottery demo and click Connect wallet. MetaMask will ask you to confirm — this only shares your public address, it doesn't grant the site access to your funds. After connecting, buy tickets and watch a round play out. The no-wallet simulator is a good first stop if you want to understand the math before spending anything.
