Step 5: Understand testnet limitations​

Rate Limiting​

Status: Rate limiting is not enforced on testnet.

Recommendation: Self-throttle to avoid abuse (10 to 50 requests per second recommended).

Faucet Deposit Cap​

Each wallet can receive up to 100,000 cumulative test USDC from the faucet.

Requests that would exceed the cap are rejected. The cap does not reset.

Market Data​

Source: Real Hyperliquid spot prices via WebSocket feed.

Behavior: Market data should be accurate, but testnet may have different liquidity than production.

Common Issues​

"Account has no funds" on testnet​

Cause: Account may not have been created yet, or balance was reset.

Fix:

  • Reconnect your wallet in the app
  • Reopen the wallet drawer to refresh the balance
  • If balance is still zero, check if testnet default behavior changed

"API key required"​

Cause: The app prompts for an API key before trading.

Fix: Follow the in-app prompt to create or connect an API key, then return to the wallet drawer.

"API key has no funds"​

Cause: The API key is connected but the balance is still zero.

Fix: Complete the faucet flow above and refresh the wallet drawer.

"I want to reset my testnet account"​

Use a different wallet address to create a new account.

"How do I get more testnet funds?"​

Use the faucet flow above to request more test USDC.
