## For Prediction Markets

To trade on Polymarket through Bullpen, you need USDC.e on Polygon:

1. Click **Deposit** in the app
2. Select **USDC on Polymarket**
3. Choose your deposit method
4. Funds arrive in your Polymarket balance

## For Perps Trading

You need USDC in your Hyperliquid perps account:

1. Deposit USDC to Hyperliquid
2. Transfer to your Perps account if needed
3. Ready to trade perps

## For Solana Spot

You need SOL for gas fees, unless you use gasless swaps for trades above \~$10. You also need the token you want to sell, or USDC/SOL if you are buying.

## Minimum Amounts

|               | Minimum                                  |
| ------------- | ---------------------------------------- |
| Solana gas    | \~0.001 SOL recommended                  |
| Gasless swaps | Available for trades \~$10 USD and above |
| Perps         | No strict minimum                        |

## Transferring Between Accounts

Use the **Transfer** button to move funds between Solana, Hyperliquid Perps, and Hyperliquid Spot.

Transfers within Hyperliquid are instant. Cross-chain transfers take 30 seconds to a few minutes.

See [Transfers](/features/transfers.md) for details.

## Withdrawing Funds

1. Go to your account/wallet section
2. Select "Withdraw"
3. Enter destination address
4. Confirm amount and network
5. Authorize the withdrawal

Withdrawals process immediately. Network confirmation times vary by chain.

## Troubleshooting

**Deposit not showing?** Verify the transaction confirmed on-chain. Cross-chain transfers may take a few minutes.

**Need gas for Solana?** Deposit a small amount of SOL, or use gasless swaps (minimum \~$10 trade).

**Perps account shows 0?** Transfer USDC from your spot or main balance into your perps account.
