​
Important considerations

  • Balance requirements — Must have sufficient balance in the source wallet
  • Instant transfer — Transfers are immediate within Hyperliquid
  • No fees — Internal transfers between spot and perp are free
  • Position checks — Cannot transfer from perp if it would cause liquidation

​
Use cases

  • Trading mode switch — Move funds between spot and perpetual trading
  • Capital allocation — Optimize fund distribution across trading strategies
  • Risk management — Move profits from perp to spot for safer storage
  • Liquidity management — Quickly reallocate capital based on opportunities
USDC in the spot wallet can be used for spot trading and token purchases. USDC in the perp wallet is used as collateral for perpetual positions.
When transferring from perp to spot, ensure you maintain sufficient margin for any open perpetual positions to avoid liquidation.
