 To handle an incoming swap request, the API processes the query through a series of strategies until one of them provides a valid response. The strategy pipelines are defined per chain in `/swapService/config` folder. The strategies can handle requests in multiple ways. The basic one is the balmy SDK strategy, which queries multiple DEXes and aggregators for a swap quote and picks the best one. Strategies can themselves run the pipelines recursively. ERC4626 wrapper can be configured for assets which are vault shares and are not supported by aggregators. The strategy will deposit or redeem vault shares and run the pipeline again, this time using the underlying asset of the vault. For a list of available strategies see `swapService/strategies` folder.
 
-The pipeline definition consits of an array of objects, selecting a strategy with it's configuration, and optional matching logic. In the following example, the pipeline is configured to query Pendle and LI.FI for swap of the Pendle PT tokens, and 1Inch and LI.FI for all other tokens.
