Cross-chain DeFi trading aggregator

A trading desk that quotes across EVM chains and DEXes, executes the best route, and hides the bridge complexity behind one click.

The Problem

Sophisticated traders open four tabs and three wallets to find a real best price. Casual users get rugged by bad rates and obvious MEV. Both groups need an aggregator that's honest about what they're paying.

The Approach
  1. 01

    Built a quote engine that aggregates spot prices from major DEXes per chain and proposes the best route, including bridge legs.

  2. 02

    Implemented MEV-aware routing — preferring private mempools and slippage limits — disclosed to the user.

  3. 03

    Designed the UI to show a transparent fee breakdown: protocol, bridge, gas, platform — no hidden numbers.

  4. 04

    Wired wallet abstraction so a user signs once per transaction even when the route spans chains.

  5. 05

    Built an indexer layer on top of TheGraph for portfolio and history views.

Aggregators that hide the cost are part of the cost. Ours doesn't.

The Outcome
  • Better realised price for traders, with the maths shown.

  • Bridge UX collapses from three steps to one.

  • MEV risk surfaced, not hidden.

  • Casual users get an honest tool; pros get a serious one.
