Size Credit Has Become 'Rheo'
Unveiling a new aesthetic - aligning with our mission to seamlessly coordinate DeFi's capital flows
We’re excited to announce that Size Credit is now Rheo!
DeFi has dissolved geographical borders, but not yet overcome its own divisions. Capital remains frenetic - pooled to largely stagnate, or evaporate without warning.
We built Size on the thesis that as sophisticated capital entered DeFi, demand for fixed-rate, fixed-maturity products would rise. A known cost of capital is a prerequisite for any institutional lender.
It was clear that existing fixed-rate AMM models would never scale. So we built our novel Term Structure Order Book (TSOB) - a model where offers express both rate and tenor, creating unified liquidity across maturities with depth.
Why ‘Rheo’?
‘Rheo’ means flow in Ancient Greek. While our model has shifted, our mission remains resolute: to coordinate DeFi’s capital flows.
The flow of new capital. The flow of adoption from variable rates to structured term premiums. The flow of trillions in credit that will one day course through DeFi.
