Creek

Creek is a gold tokenisation protocol on Sui that separates gold's value into a stable and a volatile component. Users deposit XAUm, Matrixdock's token backed one-to-one by a troy ounce of physical gold, and receive at a fixed ratio a stable-value claim called GR and a volatility claim called GY: GR collateralises zero-interest borrowing of the dollar-pegged GUSD, while GY amplifies gold's price moves with a claim on protocol yield and no liquidation line.

Pricing the store-of-value and the price-elasticity components separately lets one reserve serve conservative and aggressive demand, with collateral ratios and mint ratios written as contract parameters. Bullion is custodied by the issuer and checked onchain through reserve attestations. Cumulative volume has passed 8 million dollars, with more than 30 million dollars of XAUm, and lending and staking clear on Sui mainnet.
