+# Swap Aggregator Subgraph
+
+Basic subgraph for [Swap Aggregator Connector](https://polygonscan.com/address/0x403e1559ef503C12CF2ec8E07dBC592Ff298EEc3).
+Tracks all the calls made to the swap method and stores the data which includes:
+- connectors: The connector names array passed by the user to perform swaps on any, in preference order.
+- callData: Array of call data passed by the user - input details for the respective connectors.
+- eventName: "LogSwapAggregator(string[],string,string,bytes)"  
+- eventParam: Encoded data including connectors array, connector name where swap took place, eventName and eventParams returned by the connector where swap occured.
+
+Support added for Mainnet and Matic
+- Mainnet: [Swap Aggregator Subgraph](https://thegraph.com/hosted-service/subgraph/richa-iitr/swap-aggregator-subgraph?selected=playground) 
+- Polygon: [Swap Aggregator Subgraph](https://thegraph.com/hosted-service/subgraph/richa-iitr/swap-aggregator-subgraph-matic?selected=playground)
