A SAFE PLACE TO PRACTICE
Set up test tokens
Practice the full agreement flow with assets that have no monetary value.
ContractOS Mock USD (cUSD-TEST) is a demonstration ERC-20 token with 6 decimals. It is not official USDC, not redeemable, and not a stablecoin. Never send real assets.
1. Choose your test network
You need a browser wallet and test ETH for gas. Base’s test-funding guidance ↗
2. Select or deploy a mock token
Use an existing ContractOS test token, or deploy the pinned token yourself. Your wallet authorizes deployment; ContractOS never signs for you.
3. Get test tokens
The faucet sends 10,000 cUSD-TEST once per wallet per token contract. This is a wallet transaction and requires test ETH.
