**Note:** It is recommended to make direct function calls to the maker-otc contract if you are intending to build other smart contracts that communicate with the maker-otc contract or build a trading bot. Example of this is the [dydx exchange](https://dydx.exchange/). However, if you’re integrating this maker-otc engine for wallets or UIs, then it is recommended to use the [Oasis Direct proxy contracts](https://github.com/makerdao/oasis-direct-proxy).
