Category: DeFi · Decentralized Exchange · Web3
Platform: Web (Polygon Network)
Project Type: Automated Market Maker (AMM) & Yield Farming Protocol

Project Overview
PolySwap (https://polyswap.netlify.app) — built as PoliexSwap — is a decentralized exchange and high-yield farming protocol deployed on the Polygon network. It gives users the ability to swap tokens, provide liquidity, and earn yield on their assets directly from a non-custodial Web3 interface, without intermediaries and without leaving their wallets. Built by Cuboid, it sits in the same product category as PancakeSwap on BSC — but positioned specifically for Polygon's faster, lower-cost infrastructure.
The Problem
Ethereum's gas fees made DeFi participation prohibitively expensive for smaller investors. Binance Smart Chain addressed the cost problem but introduced centralization trade-offs many users weren't comfortable with. Polygon emerged as a legitimate Layer 2 alternative — fast, cheap, and EVM-compatible — but lacked a native, fully-featured AMM and yield farming platform at the time.
The opportunity was clear: a first-mover DEX on Polygon that combined token swapping, liquidity provision, and high-yield farming in a single, clean interface built for the Polygon-native user.
Our Solution
Cuboid designed and developed the full PolySwap platform — smart contract integration, liquidity pool architecture, yield farming interface, and wallet connectivity — on Polygon's EVM-compatible chain. The interface was modeled on the established DEX UX patterns users already knew from Uniswap and PancakeSwap, lowering the barrier to entry while delivering Polygon's speed and cost advantages underneath.
The platform was built to be genuinely non-custodial throughout — users connect their own wallets, execute swaps and deposits directly on-chain, and retain full control of their assets at every step.
Key Features & Capabilities
Token Swapping (AMM) — An automated market maker enabling direct token-to-token swaps on Polygon without order books, central servers, or custodial risk. Pricing is determined algorithmically by liquidity pool ratios, ensuring continuous liquidity at all times.
Liquidity Provision — Users deposit token pairs into liquidity pools and earn a share of all swap fees generated by that pool — passive yield tied directly to platform trading volume rather than speculative token price.
High-Yield Farming — Liquidity providers receive LP tokens representing their pool share, which can be staked in farming contracts to earn additional protocol rewards on top of swap fees. The dual-layer yield model — fees plus farming rewards — was positioned as the platform's primary value proposition for capital deployment on Polygon.
Non-Custodial & Permissionless — No sign-up, no KYC, no custody. Users connect a compatible Web3 wallet and interact with smart contracts directly. Any Polygon-compatible token pair can be added as a liquidity pool without platform approval.
Polygon-Native Performance — Transactions settle in seconds at a fraction of Ethereum mainnet gas costs, making frequent farming interactions and compounding strategies economically viable for users of any portfolio size.
Why Polygon
The decision to build on Polygon rather than Ethereum mainnet or BSC was deliberate. Polygon's EVM compatibility meant existing Ethereum tooling, wallets, and token standards worked without modification. Its transaction costs and speed made high-frequency DeFi interactions — swaps, deposits, harvest cycles — practical for retail users, not just whales.
Positioning PolySwap as the first high-yield AMM on Polygon was a first-mover bet on a network that has since grown into one of the most active EVM chains in DeFi.
Final Outcome
PolySwap demonstrates Cuboid's capability across the full DeFi product stack — AMM smart contract integration, liquidity pool architecture, yield farming mechanics, and a consumer-grade Web3 interface built for a specific chain's competitive advantage. It's a project that required both technical precision and an understanding of how DeFi users think about capital, risk, and yield. TOMI – Web3 Ecosystem Platform
TOMI is a Web3 ecosystem platform built to support blockchain-powered products, decentralized services, and digital ownership experiences. The website acts as the main entry point for users to understand the TOMI ecosystem, explore its products, and interact with Web3-focused services through a modern, scalable, and performance-driven web experience.
My role focused on developing and improving the frontend architecture of the platform using modern web technologies. I worked on creating reusable components, responsive layouts, and smooth user flows that could support a premium Web3 product experience across desktop and mobile devices. The goal was to make the platform visually polished while keeping it fast, reliable, and easy to use.
From a technical perspective, I contributed to Web3-related integrations, dynamic data handling, API connectivity, and blockchain-focused user flows. The platform required careful handling of asynchronous data, wallet-related states, transaction-driven interactions, and real-time updates from external services. I focused on making these flows stable, user-friendly, and scalable for production use.
Performance and scalability were also key priorities. I worked on optimizing page load speed, improving rendering behavior, managing reusable UI structures, and ensuring the website performed consistently across browsers and screen sizes. The implementation was designed to support future ecosystem expansion without making the codebase difficult to maintain.
The project involved technologies such as Next.js, React.js, TypeScript, REST APIs, Web3 integrations, blockchain data services, Git, and modern deployment workflows. The final result was a scalable and production-ready Web3 platform experience that helped present the TOMI ecosystem in a clear, technical, and user-focused way.
