SFI

The initial application of the payback waterfall is split between two primary tranches. -A yield enhanced “A” tranche. -A risk mitigated super-senior “AA” tranche.

Added liquidity, when removed, is used to pay back the initial principal of AA holders before paying the principal and interest of the yield enhanced A tranche. In exchange for this enhanced return, participants of the A tranche must stake Saffron’s native tokens (SFI) to mitigate against failures on the underlying platform (such as Compound, Aave, or Curve). The Saffron protocol in this scenario acts as an escrow service for transfer of risk between A tranche participants and AA tranche participants. Saffron also includes an “S” tranche for allocating liquidity efficiently as it is needed based on a tranche balancing algorithm.
