We are Ripae Finance, a cross-chain algorithmic stable coin pegged to each native chain we are deployed on. An Algorithmic Stable Coin (ASC) is a non-collateralized stablecoin tailored for improving price stability. The beauty of algorithmic stable coins is that they are much more capital efficient than their collateralized cousins. Ripae finance will, with its experienced team, work towards expanding this idea of capital-efficient algorithmic stable coin and build on previous iterations to expand the basis of the ecosystem.
