The Mission
“To make trading and liquidity provision more capital efficient and more compelling by aligning incentives directly with user activity.”
Core Objectives
- Deliver a fast, clean swap interface that surfaces rewards without adding friction
- Support concentrated liquidity tooling for both advanced users and newcomers
- Present incentive mechanics — gas rebates, swap rewards, trader points — transparently and intuitively
- Integrate deeply with Superposition's smart contracts for accurate pool interaction and transaction execution
The Challenge
DEX products often look identical and compete only on liquidity depth. New incentive models are hard to explain without cluttering the trading UX — traders want speed and clarity, not pages of DeFi theory. Reward systems can quickly become confusing or feel gimmicky if poorly presented, eroding trust before a user ever executes a swap.
The swap UI had to stay clean even with multiple reward types and route components visible simultaneously. Liquidity tools needed to support advanced LPs without intimidating new participants. Incentive mechanics had to feel transparent and worth engaging with — and the overall product had to communicate genuine novelty without sacrificing the credibility traders expect from a production-grade DEX.
What We Built
Swap & Liquidity Interface
A clean, fast-execution trading UI handling swap routing, slippage configuration and multi-reward display — keeping the experience focused without hiding Longtail's depth.
Incentive & Rewards UX
Transparent presentation of swap rewards, gas rebates and trader incentive mechanics — designed to feel credible and engaging without overwhelming the core trading flow.
Smart Contract Integrations
Direct integration with Longtail's AMM contracts for pool interaction, liquidity management and transaction execution — covering both standard and concentrated liquidity positions.
Portfolio & Position Interface
A position and portfolio layer giving repeat traders and LPs visibility over their active positions, accrued rewards and historical activity in one coherent view.
Technical Architecture
A front-end trading experience built on top of Longtail's concentrated liquidity AMM contracts — integrating swap execution, liquidity management, reward tracking and position management into a cohesive product layer designed for speed and transparency.
Real Impact.
Longtail delivered a production-grade DEX experience on Superposition — proving that trader-first incentive mechanics and concentrated liquidity can be packaged into a product that is both technically rigorous and genuinely compelling to use.
