infiniFi USD

infiniFi rebuilds fractional-reserve banking on Ethereum, tranches and all. Depositors hand over stablecoins and receive iUSD, a receipt dollar that the protocol backs by deploying the pooled funds into yield sources, lower-risk money markets like Aave and Fluid for liquid capital, higher-return strategies for capital that users agree to lock. Holders choose their risk: stake iUSD into liquid siUSD for a modest yield, or lock it into illiquid liUSD for more. A coded loss waterfall decides who absorbs a shortfall first, with locked, highest-yield holders in the front line and plain iUSD holders protected last, an explicit ordering most stablecoins leave unstated. Redemption runs onchain against those reserves through the protocol rather than a company. Launched in 2025 with tens of millions in early deposits, iUSD is a bet that transparent onchain fractional banking can pay more without hidden leverage.
