Spectra is bringing fixed-rate markets and tradable yield to the Stellar network, introducing a new layer to its onchain economy. The protocol splits yield-bearing assets into two separate tokens to allow independent trading of fixed returns and variable yield exposure.
As an open, permissionless interest-rate derivatives protocol, Spectra takes a yield-bearing asset and divides it into Principal Tokens (PT) and Yield Tokens (YT). Once split, each component trades independently on its own market.
The Principal Token represents the fixed-yield side of the arrangement. Users purchase the principal at a discount to its face value, and at maturity, the token can be redeemed for its full fixed value, offering a predictable return over a set period. Meanwhile, the Yield Token gives holders exposure specifically to the future yield of the underlying asset without owning the asset itself, allowing the yield to be traded as its own instrument.
Commentator Marco Salzmann noted that the integration fits into a broader pattern on Stellar, which has been expanding across tokenized assets, lending, yield markets, and settlement infrastructure. Each layer builds upon the capital already present onchain.
Independent confirmation of the integration timeline is provided by Stellar’s Security Audit Bank, which lists an entry for "Spectra – Interest Rate Markets on Stellar." The associated Certora audit for the integration was completed on May 18, 2026.
Spectra is not alone in pursuing this type of infrastructure on the network. Another protocol, XCCY, is building a fixed-rate engine on Stellar designed to target fixed yield, fixed-rate borrowing, and hedging against variable interest rates. Both developments highlight rising sector demand for interest-rate tools on Stellar.
These developments align with the Stellar Development Foundation's 2026 strategy, which focuses on bringing more capital onchain and increasing the efficiency of existing onchain assets. Tools like Spectra provide participants with additional mechanisms to manage risk and return as more asset types settle on the network.
