What is the Hyperliquid Referral Code?
The Hyperliquid referral code COINPERPS applies a 4% discount to the trading fees you pay on the protocol. Unlike the centralised venues on this page, that number is set by Hyperliquid itself rather than negotiated per partner, so every valid referral code grants the same 4%.
The discount is capped by volume rather than by time. It applies to your first 25 million dollars of trading volume and then stops, with no expiry date in between. Referrers earn 10% of the fees their referees pay, up to the referee’s first billion dollars of volume.
Hyperliquid is fully onchain, which changes the mechanics. There is no identity verification and no sign-up bonus programme, because there is no company issuing vouchers. Referral rewards are not swept into your balance automatically: you claim them from the Referrals page once they pass one dollar, and they arrive in your spot balance.
Two limits are easy to miss. The discount does not extend to vaults or sub-accounts, which the clearinghouse treats as independent accounts, and the referrer attached at sign-up cannot be changed later.
