Status: sunset

Felix Exchange was a perp dex run by Felix, the HyperEVM lending protocol, under the onchain name flx. It used HIP-3, which lets anyone who stakes 500,000 HYPE deploy their own perpetual-futures markets on HyperCore, Hyperliquid’s trading engine and order book. flx listed stocks, indices, commodities and a few crypto markets, with USDH as collateral.

Felix has closed it. Its docs publish an FLX HIP-3 Sunset Guide, and on November 4, 2026 Hyperliquid’s info API showed all 16 flx assets delisted, with zero open interest and zero 24-hour volume: TSLA, NVDA, CRCL, COIN, XMR, GOLD, SILVER, OIL, GAS, BTC, COPPER, PALLADIUM, PLATINUM, USDE, USA500 and USA100.

How settlement worked

The sunset guide set settlement for Friday, June 19. The guide doesn’t print the year; June 19 fell on a Friday in 2026. Markets settled one hour apart, starting at 5:30 PM ET, in this order:

1. Commodities: Oil, Silver, Gold, Palladium, Gas, Platinum, Copper.
2. Equities: NVDA, COIN, TSLA, CRCL, USA500, USA100.
3. Crypto: XMR, USDE.

Prices were locked using RedStone oracle data:

Group	Settlement price locked to
Commodities	Friday 1 PM ET close
Equities	Thursday 4 PM ET close
Crypto	10-minute EMA ending Friday 4 PM ET

The guide’s settlement order doesn’t list flx:BTC, which the API also shows as delisted; we couldn’t confirm when or how that market settled.

What holders should do now

Positions on delisted markets can’t be reopened or traded. If you used Felix Exchange:

1. Check your Hyperliquid account. Look up your address on the official explorer or HypurrScan for any remaining balance after settlement.
2. Deal with leftover USDH. flx was USDH-margined, and USDH is being wound down. Bridge, the issuer, redeems at par through redeem.bridge.xyz after KYC; selling on Hyperliquid’s thin USDH/USDC book may cost you a discount. Details are in Native Markets / USDH.
3. Use official channels only. For questions, use the support routes in Felix’s docs. Ignore DMs and “claim” links, and check addresses against official links.

What it cost, for the record

flx used Hyperliquid’s HIP-3 base fee schedule: 0.090% taker and 0.030% maker at tier 0, twice the rate on Hyperliquid’s validator-run perps.

Felix is still running

The sunset covers only the perp dex. Felix’s lending products on HyperEVM, Hyperliquid’s smart-contract chain, are separate: the feUSD CDP (a Liquity v2-style stablecoin mint), Morpho-based Vanilla Markets and Felix-curated vaults. Those are covered in our Felix dossier and in HyperLend vs Felix. Felix has also said it is sunsetting USDhl, an M0-based stablecoin it built.

Alternatives

For stock, index and commodity perps on Hyperliquid today, trade[XYZ] runs by far the largest HIP-3 dex, and Paragon lists index and Treasury-yield perps. Ventuals, another USDH-margined HIP-3 dex, has also shut. All HIP-3 markets are leveraged, and deployers can halt and settle them, as flx shows.
