Giving the HyperCore system address as the receiving address
Hyperliquid's docs describe 0x2222222222222222222222222222222222222222 as the system address that moves HYPE from HyperEVM into HyperCore (checked on 12 October 2026). That is an address you send to from your own wallet after the swap, if you want the HYPE in your trading account. Entering it as the receiving address here sends the payout into a system contract on someone else's behalf — not into your account.
