Spectra launches on Flare, giving users a new way to trade and manage yield by splitting fixed and variable returns.

Summary

• Spectra goes live on Flare, enabling users to trade fixed and variable yield by splitting interest-bearing assets.
• By separating principal and yield tokens, Spectra lets investors lock in fixed returns or trade variable-rate exposure.
• Spectra’s yield tokenization brings new tools to Flare, supporting advanced DeFi strategies and boosting capital efficiency.

Spectra, a yield trading platform, is now live on Flare, introducing a new way for users to buy, sell, and manage yield from interest-bearing assets. The platform allows users to separate the fixed and variable components of yield, a structure that could expand how investors earn, trade, and manage returns across the Flare network.

How does Spectra work?

At its core, Spectra protocol splits any yield-bearing tokens (e.g. sFLR) on Flare into two parts that can be used independently. The Principal Tokens (PTs) represent the principal value of the underlying asset and are designed to reach their full face value at maturity. Holding PTs allows users to lock in a predictable, fixed return. 

Yield Tokens (YTs), on the other hand, represent the right to future yield that the asset will generate. YTs can be traded independently, giving users a way to speculate on or hedge against changes in yield rates.

By making yield itself composable and tradable, Spectra opens the door to new, flexible DeFi strategies. Users can lock in income, take on leveraged yield exposure, or use these tokens as building blocks for new products in the Flare ecosystem. The tokens could also serve as collateral in future lending protocols, adding potential utilities across the ecosystem.

The arrival of yield tokenization by Spectra marks a notable development for Flare. Developers and liquidity providers gain access to new building blocks for products such as fixed-rate lending, leveraged yield markets, or structured financial products. The model also increases capital efficiency by allowing the same assets to circulate across multiple protocols, which is an important characteristic for networks aiming to attract institutional participation.

Spectra introduces a core financial primitive to the Flare ecosystem — yield tokenization — which marks a major step toward a more mature, interconnected onchain economy.  Not only does this broaden the toolkit available to developers and liquidity providers, but it also strengthens the foundation for long-term ecosystem growth and institutional adoption. 

Who is it for?

Spectra allows anyone to launch their own yield-trading market for assets such as sFLR or FAssets and earn fees on swaps in a model similar to Uniswap. While this system attracts advanced DeFi users and institutions seeking control over on-chain returns, newcomers and the broader Flare community can also use Spectra.

The Fixed Rate tool in the Spectra app allows anyone to obtain PTs and lock in a known, predictable outcome, for example: pay 1 today, receive ~1.1 in X days. It’s a way for users to gain initial experience with yield while still leaving room to explore more advanced strategies over time.

What are the details of the initial pools and liquidity?

At launch, Spectra includes a liquidity pool for its native sFLR token that supports both fixed-rate (where PTs are minted and traded) and yield-leverage markets  (where YTs are minted and traded). Liquidity providers earn swap fees from PT and YT trading and may receive additional rewards such as rFLR or SPECTRA. Expanding liquidity across Spectra’s pools on Flare will be a priority in the early weeks, with Firelight’s stXRP expected to be added next, increasing the range of markets available to users and developers.

Users can engage with the protocol by holding PTs for fixed returns, trading YTs to adjust yield exposure, or supplying liquidity to support and earn trading fees. Spectra is now available on Flare, with more information accessible through its official website.
