The following diagram summarizes the code architecture:
The TychoRouterEncoder and TychoExecutorEncoder are responsible for validating the solutions of orders and providing you with a list of transactions that you must execute against the TychoRouter or Executors.
Internally, both encoders choose the appropriate SwapEncoder(s) to encode the individual swaps, which depend on the protocols used in the solution.
The TychoRouter calls one or more Executors (corresponding with the output of the SwapEncoders) to interact with the correct protocol and perform each swap of the solution. The TychoRouter optionally verifies that the user receives a minimum amount of the output token.
The TychoRouterEncoder uses a StrategyEncoder that it choses automatically depending on the solution (see more about strategies ).
If you select the ExecutorStrategyEncoder during setup, you must execute the outputted calldata directly against the Executor which corresponds to the solution’s swap’s protocol. Beware that you are responsible for performing any necessary output amount checks. This strategy is useful if you want to call Tycho executors through your own router.
