Testnet faucet

To use the testnet faucet, you need to have deposited on mainnet with the same address. You can then claim 1,000 mock USDC from the testnet faucet: https://app.hyperliquid-testnet.xyz/drip

If you are using an email login, Privy generates a different wallet address for mainnet and testnet. You can Export your email wallet from mainnet, import it into a wallet extension (e.g., Rabby or Metamask), and connect it to testnet.
