#### Do I need a token to use HyperFlow?

No. No token is required for any HyperFlow product, and fee savings on perps/spot apply without holding or staking anything.

#### Which wallets are supported?

Any standard EVM wallet (injected or WalletConnect), plus email sign-in with an embedded wallet for a CEX-like onboarding experience.

#### Where do I get support?

The fastest channel is [Discord](https://discord.gg/GGDmD4K9CK). Announcements are posted on [X](https://x.com/HyperFlow_fun) and [Telegram](https://t.me/hyperflow_fun).

## Troubleshooting

#### My HyperEVM transaction failed: gas exceeds block gas limit

This is the HyperEVM **small-blocks** limitation: transactions signed with more than 2M gas fail unless your address has **Big Blocks** enabled.

**Check your status:**

```bash
curl --location 'https://rpc.hyperliquid.xyz/evm' \
  --header 'Content-Type: application/json' \
  --data '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "eth_usingBigBlocks",
    "params": { "address": "<YOUR_WALLET_ADDRESS>" }
  }'
```

**Enable Big Blocks:**

1. Deposit USDC to [Hyperliquid](https://app.hyperliquid.xyz/) (an active account is required).
2. Visit the [HyperEVM block toggle](https://hyperevm-block-toggle.vercel.app/) (a community-maintained tool), connect your wallet, and sign to enable Big Blocks.

Once enabled, high-gas transactions will process normally.
