NEXAPOOL

NexaPool is an automated market maker for pools of 2, 3, or 10,000 stablecoins. It unlocks capital efficiency by bringing concentrated liquidity to higher dimensions.

By bending liquidity into a torus-shaped universe, Nexa unlocks concentrated liquidity for three or more stablecoins at once. This isn't your usual 2D liquidity grid—it's an entirely new dimension where LPs can laser-focus around the sacred $1 mark, while still guaranteeing fair prices even if an entire stablecoin implodes to zero.

It's like Uniswap V3's surgical precision colliding head-on with Curve's bulletproof stability, and the result is something that shouldn't even exist, but somehow, it does.

Nexa is the AMM where capital efficiency doesn't just scale, it warps!

We built NexaPool as a next-gen AMM using Arbitrum Stylus for high-performance math on-chain.

At its core is a Torus Invariant, combining spherical and circular invariants to curve liquidity smoothly across multiple stablecoins. Swaps are solved using a custom Newton’s Method implementation with a gradient descent fallback for stability under edge conditions.

Running in Stylus gives us C-level speed and major gas savings versus Solidity. Frontend is built with Next.js 15, TypeScript, Tailwind, and Framer Motion, integrated with Pyth oracles for real-time prices and 1inch for smart routing.

We also implemented a custom WASM-optimized solver and dynamic fallback chaining, cutting computation gas by ~40%. Partner integrations: Arbitrum Stylus (performance), Pyth (price feeds), 1inch (routing).
