Spectra is a protocol for future yield tokenisation.DeFi users can deposit their interest bearing tokens of other protocols during defined future periods and trade in advance the future yield that their funds will generate. Spectra works by placing Interest Bearing Tokens (IBT) or any yield-bearing asset for a fixed duration of time in a smart contract and issuing Future Yield Tokens (FYT) in return. The yield generated by these assets is directly received by the smart contract, and only the holder of the FYTs can redeem the corresponding underlying yield at the end of the period.As FYTs are regular ERC20 tokens, they can be freely traded, opening up a new market for future yield.
