# Dex Aggregator for Jediswap v1 pools

This is a lightweight dex aggregator. It exposes a simple REST based API service to get trade quotes for a token pair and manage the underlying datastore.

To compile `cargo build --release` (using rust version 1.80.0)

To run `cargo run --release` - dex_config.toml holds configurable values

Server will be available at http://localhost:3000

Sample query to get [trade quotes](http://localhost:3000/quotes?sellTokenAddress=0x53c91253bc9682c04929ca02ed00b3e423f6710d2ee7e0d5ebb06f3ecf368a8&buyTokenAddress=0x4718f5a0fc34cc1af16a1cdee98ffb20c31f5cd61d6ab07201858f4287c938d&sellAmount=10000000000&getLatest=true) - 

The `getLatest` query parameter lets you use pre indexed data (if false or not present) and get latest reserves data (if true)

The basic idea is to find all possible paths to trade between a token pair and then do gradient optimisation to optimise an objective function - maximise output when given an input amount and minimise input when given an output amount.
