f(x) Protocol is Aladdin DAO's dual-token stablecoin and leveraged-trading platform on Ethereum. It mints fxUSD — a decentralized stablecoin backed by wstETH and WBTC — alongside fixed-leverage xPOSITION/sPOSITION tokens.
One collateral pool splits onto two pans. fxUSD (stable, senior) is paid first; xPOSITION (leverage, junior) absorbs every price swing. Slide the collateral price and watch the beam tilt.
fxUSD holds its peg — the pool still fully covers the senior claim.
xPOSITION is the residual equity: it eats the volatility so the stable side doesn't have to.

Existing decentralised stablecoins are either over-collateralised and capital-inefficient (DAI/LUSD) or rely on off-chain custodians (USDe) — and leveraged ETH/BTC trading typically requires perp DEXes with funding-rate exposure and instant-liquidation risk.
f(x) Protocol couples a leveraged-trading market for ETH/BTC with a stablecoin (fxUSD) minted from the same collateral pool. The long-leverage demand from xPOSITION holders subsidises the Stability Pool that defends fxUSD's peg, while users can exit fxUSD instantly by redeeming for wstETH or WBTC at the oracle price.
Category creator for the 'dual-token stablecoin' design — fxUSD is minted as a by-product of leveraged trading, eliminating funding fees and replacing instant liquidation with a Liquidation Brake. Fully on-chain, fully audited, no centralised custody.
