SwaptoX solves the inefficiency of existing DEX aggregators by providing users with a transparent, multi-path swap engine.
Instead of only showing a default route, SwaptoX calculates and displays more than ten possible swap paths across Base, including gas cost estimates for each.
This allows users to choose the truly optimal route, making trading cheaper, safer, and more transparent.
In addition, SwaptoX offers advanced features such as token-to-token, token-to-ETH, and multi-hop swaps, all with a seamless UI and multi-language support.

One of the biggest challenges was ensuring stable multi-hop swaps across different liquidity sources, such as Balancer V2, Uniswap V2, and Uniswap V3 (on which many Base pools are built).
The routing engine often produced unstable results due to differences in pool structures and fee models. To solve this, I designed a custom path evaluation algorithm that normalizes these variations, enabling accurate and consistent multi-hop routing.

Another key challenge was maintaining reliable token-to-USD price feeds for hundreds of tokens.
Since not all tokens have direct stablecoin pairs, I had to build a hybrid approach that aggregates on-chain prices and fallback paths, ensuring users always see transparent and accurate USD values.
Together, these solutions made SwaptoX swaps both reliable and user-friendly.
