SwapX — Meta-Aggregator DEX Swap Platform
A cross-chain DEX meta-aggregator that routes trades across multiple decentralized exchange aggregators to find the best net rate after gas, with MEV protection.
Overview
SwapX (live at swaap.info) is a cross-chain decentralized exchange meta-aggregator I co-founded alongside a technical co-founder who leads engineering. Rather than routing trades through a single DEX aggregator, SwapX queries multiple aggregators at once and executes through whichever offers the best net rate after gas, with cross-chain routing and MEV protection built in. My role is product and strategy: defining MVP scope, wallet and UX decisions, and writing the initial product requirements document, while my co-founder owns the technical build.
The Problem
Individual DEX aggregators each optimize routing within their own liquidity sources, but no single aggregator consistently offers the best price on every trade. Users who want the genuinely best rate have to manually check multiple aggregators themselves, and most don’t bother. Cross-chain swaps add another layer of friction, usually requiring separate bridging steps. SwapX’s premise is that a meta-layer over existing aggregators, plus native cross-chain routing, closes that gap without asking users to comparison-shop themselves.
Architecture
Aggregation Layer queries multiple underlying DEX aggregators, including OpenOcean and KyberSwap, in parallel for same-chain swaps, comparing quotes to route each trade to the best net price after gas.
Cross-Chain Routing uses LI.FI to handle swaps that span multiple blockchains, abstracting away what would otherwise be a manual bridge-then-swap process for the user.
MEV Protection is built into the execution layer to reduce the risk of trades being sandwiched or front-run during execution.
Product Definition, my primary contribution, covers the MVP feature set, wallet connection and transaction UX, and the initial requirements document that scoped what shipped in the first production version.
Results
- Live, production deployment at swaap.info
- Cross-chain swap routing functioning end-to-end via LI.FI
- Aggregates quotes across multiple DEX aggregators rather than relying on a single liquidity source
Technical Challenges
The main product challenge was scoping the MVP tightly enough to actually ship: cross-chain DeFi products have a lot of surface area (chain support, token lists, slippage handling, wallet edge cases), and deciding what to defer past v1 was as important as deciding what to build. That scoping work, along with the wallet/UX decisions and the initial requirements document, was my primary contribution to the project.
