Setting Up Your Wallet

Install MetaMask - This is the most beginner-friendly wallet for Ethereum networks. Go to metamask.io and install the browser extension or mobile app. Create a new wallet and securely store your seed phrase (write it down offline and keep it safe). Make sure you have the Metamask browser extension pinned for easy use. Add Sepolia Testnet - In MetaMask, click the network dropdown at the top left and search for Sepolia under test networks. Toggle turn test networks on.

​
Getting Test ETH

Use a Sepolia Faucet - Visit faucets like sepolia-faucet.pk910.de or faucets.chain.link. You’ll need to connect your wallet and request test ETH. Alternative Faucets - If one doesn’t work, try Alchemy’s faucet (requires creating a free account) or Infura’s faucet. These services often have daily limits, so you might need to wait between requests.

​
Getting Test USDC

USDC Faucet - Circle offers a USDC faucet. Make sure you select the Sepolia network. Add USDC Token - If you do not see the USDC show up in your wallet after a few minutes, you may need to add in the USDC token to MetaMask. To do this, in MetaMask, under the “tokens” tab, click the “more” icon to see “+Import tokens.” Paste the USDC contract address 0x1c7d4b196cb0c7b01d743fbc6116a902379c7238, and the token symbol and decimals should auto-populate.

Important Reminders

Never use real money - Testnet tokens have no real value and are only for testing and learning. Keep your seed phrase secure - This is your only way to recover your wallet if you lose access. The address you made will work on mainnet accounts that can hold tokens with value. Double-check networks - Always verify you’re on the correct testnet before making transactions. Gas fees - You’ll need some test ETH to pay for transaction fees (gas) when moving tokens around.
