How to Prepare for USDC Testing
This guide shows how to set up a wallet for Ethereum Sepolia, obtain test ETH (for gas) and Testnet USDC, and import the USDC token into your wallet.
1 – Install a Wallet that Supports Sepolia
Desktop example: Metamask Chrome browser extension
2 – Enable Sepolia Test Network
Open Metamask.
Tap or click the network selector at the top.
Turn on Show test networks.
Select Sepolia Test Network.
3 – Get Sepolia ETH (needed for gas fees)
Copy your Sepolia wallet address
In Metamask, select SepoliaETH → Receive → Copy address.
Visit a Sepolia faucet (e.g. Sepolia PoW Faucet).
Paste your address and request coins.
The PoW faucet requires a brief “mining” step that consumes CPU resources.
You will use this ETH later to pay gas when sending USDC.
4 – Import USDC Token (Sepolia)
In Metamask, still on Sepolia, choose Import tokens.
Paste the token address:
0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238
Metamask should auto-fill Token Symbol (USDC) and Decimals (6).
Confirm Import.
5 – Get Testnet USDC on Sepolia
Copy your Sepolia wallet address again (step 3.1).
Open the Circle Testnet Faucet.
Select Ethereum Sepolia as the network.
Paste your address and click Send 10 USDC.
Wait for the transaction confirmation in Metamask.
6 – Next Steps
Use the SepoliaETH as gas to send USDC in your test payment flows.
Repeat the faucet steps whenever you need additional ETH or USDC (most faucets have 24-hour limits).
For production, remove test networks and connect to Mainnet with real ETH and USDC.
