-## Squid on Osmosis
+## Contracts
 
-The Squid contract to be deployed on Osmosis is responsible for handling two things:
-
-1. Receive swap path and minimum output amount and execute it. 
-    - Path is a sequence of pools that will be used to go from token A to token B, the same way as in the Uniswap V2 router.
-2. In case of a successful swap execute specified ‘after swap action’ which can be either bank send or contract call or ibc transfer.
-
-Since the only responsibility of this contract is to perform swaps it is stateless and does not require any ownership or pausable functions.
-
-The contract also handles fallback scenarios for ibc-transfers, in case of packet failure or timeout contract will transfer swapped funds to the specified ‘fallback_address’.
