# Available oracles

The SmartPiggies app offers a handful of underlyings, but a limited and specific set. These have been tested, and each underlying requires a unique resolver to return the price of the underlying if the piggy is executed. Currently, SmartPiggies, supports its own oracles which fetch data when requested. As SmartPiggies requires certain features from an oracle, it is possible to use other oracles with SmartPiggies, if they execute in the way the SmartPiggies contract expects. If user would like more resolvers or the use of other oracle providers, please visit the SmartPiggies [discord](https://discord.gg/hQe39uG) to make requests.

The following is a list of available resolvers that can be used on the SmartPiggies platform.
