From zero to your first on-chain action. This guide uses Sepolia testnet — no real money involved at any step. The same setup unlocks the live demos: the lottery, the raffle, and the synthCore Access Pass mint.
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. The amounts here are tiny — lottery tickets run ~Ξ0.005 and the SynthCorePass starts at Ξ0.001 — so any faucet amount is plenty.
| faucet | requires |
|---|---|
| Google Cloud Web3 Faucet | Google account |
| Alchemy Sepolia Faucet | Free Alchemy account |
| pk910 PoW Faucet | No account — runs in browser, slower but higher max daily volume |
| naterich.net faucet | No account — self-hosted browser proof-of-work; connect a wallet, mine ~7.5 min, it drips straight to you |
For the account-based faucets, paste your wallet address (starts with 0x, shown at the top of MetaMask) and wait about 30 seconds. If one is rate-limiting you, try another. The site's own faucet instead runs a proof-of-work in your browser and drips to the wallet you connect — no account, no third-party site.
4. Connect and play
You're set. Open any live demo and click Connect wallet — MetaMask only shares your public address, it never grants the site access to your funds. The same Sepolia test ETH covers all of them:
Quintile Lottery — buy a ticket and watch a round resolve on-chain, with roughly a one-in-five win rate. New to it? Start with the no-wallet simulator to learn the math first.
Raffle — sponsor-funded prize pots with open, token-gated, or allowlist entry.
synthCore Mint & Access — mint the SynthCorePass for standing access to finer-grain research. A one-off x402 pay-per-window activity feed is built but not live yet.
