The Assistance Fund and HYPE buybacks

Most exchanges keep their fees. Hyperliquid’s documentation says its fees are directed to the community instead: to the HLP vault, to the deployers of markets, and to the Assistance Fund. The Assistance Fund is the part that turns trading activity into steady buying of HYPE.

How it works

The Assistance Fund is a system address: 0xfefefefefefefefefefefefefefefefefefefefe. Nobody has a private key to it. Instead, the chain itself converts the fees it receives into HYPE “in a fully automated manner as part of the L1 execution”, in the docs’ words. No team decides when to buy or how much. It happens as a rule of the protocol.

An analogy: imagine a stock exchange whose rulebook says a fixed share of every commission must be used to buy the exchange’s own shares on the open market, and the bought shares are locked in a vault no one can open. That is roughly what the fund does, except the rule is enforced by code and the vault is a public address.

What feeds the fund

Source	What the docs say
Trading fees	The fund converts trading fees to HYPE automatically. Hyperliquid’s 101 page describes >$1B in annualized fees going toward buybacks.
Spot fees in other quote tokens	For spot pairs quoted in tokens other than USDC, quote-side fees go to the fund (HIP-1).
Aligned stablecoin yield	Under AQAv2, stablecoin deployers share ~90% of cost-adjusted reserve yield with the protocol, sent to the fund in 30-day intervals (USDH and aligned quote assets).
Outside projects (voluntary)	Kinetiq’s KIP-5 sends every KNTQ it buys back to the same address.

For scale: DefiLlama recorded about $901M in Hyperliquid fees over the 12 months to 4 November 2026 and about $85.7M in the last 30 days.

The numbers on 4 November 2026

From the Hyperliquid info API (tokenDetails for HYPE, 07:27 UTC):

Field	Value
HYPE held by the Assistance Fund	~48.65M
Value at the $85.15 HYPE perp mark	~$4.1B
Share of 1B max supply	~4.9%
HYPE “circulating supply” (API field)	~301.7M
HYPE “total supply” (API field)	~998.8M

The fund’s balance is about 16% of what the API counts as circulating supply.

“Burned” vs “held”: read the fine print

Hyperliquid’s fee docs say “HYPE in the assistance fund is burned, removing the tokens permanently from the circulating and total supply.” The API’s own fields treat it a little differently: the fund’s HYPE appears in a list of non-circulating balances, and the totalSupply figure (998.8M) doesn’t subtract it. So:

• If you count the fund as burned, effective total supply is roughly 950M.
• If you take the API’s totalSupply field at face value, it’s 998.8M.

Both describe the same coins. Data sites pick one convention or the other, which is why HYPE supply numbers differ between sources. The tokens can’t be spent by anyone either way.

Why it matters to you

• Buying is tied to usage, not to a treasury decision. When trading volume rises, so do fees and so does buying. When volume falls, buying slows.
• It shapes HYPE’s supply, not its price. Buybacks remove tokens from the market over time. They don’t set a floor and they can’t stop the price from falling.
• It’s verifiable. You can check the fund’s balance yourself on any Hyperliquid explorer or via the API.
