Fixed Income DEX

The Challenge

Bringing institutional-grade fixed income trading on-chain is a fundamentally different design problem than spot or perpetual trading. The product needed to communicate complex bond market concepts — yield curves, duration, maturity, coupon rates — in a DeFi-native interface, all backed by Filecoin infrastructure.

The target users were sophisticated: TradFi professionals exploring on-chain bonds for the first time, and DeFi-native users who understood crypto but not fixed income markets.

The Approach

I designed order book interfaces for fixed income products, translating TradFi conventions into DeFi patterns. The key challenge was information density — bond traders need a lot of data at once, but DeFi interfaces tend toward minimalism.

• Yield visualisations: Interactive yield curves that make maturity and rate relationships intuitive, even for users new to fixed income.
• Maturity calendars: Visual timelines showing bond lifecycles, reducing the cognitive load of tracking multiple positions across different maturities.
• Order book clarity: Adapted limit order book patterns from equity markets to work with bond-specific parameters (face value, coupon, duration).

Key Design Decisions

I chose Bloomberg-style information density adapted for Web3 mental models. TradFi users arriving on-chain shouldn't feel lost — the interface speaks their language while being transparent about on-chain settlement mechanics.

Progressive complexity was crucial: the default view shows essential metrics (yield, maturity, rating), with drill-down to full bond specifications, historical pricing, and on-chain verification.

The Outcome

A live protocol enabling decentralised fixed income trading. The design system successfully bridges the familiarity of institutional finance interfaces with the transparency of on-chain settlement — proving that DeFi can serve TradFi-grade use cases without sacrificing usability.
