# The role of gas price updater bots in Mangrove

Mangrove needs the gas price to [determine the bounty](https://docs.mangrove.exchange/dev/protocol/technical-references/makers/offer-provisions#provision-calculation) of takers for removing a failing offer from a list. On chains where the gas price varies, Mangrove [uses](https://docs.mangrove.exchange/dev/protocol/technical-references/governance-parameters/global-variables) an [oracle](https://docs.mangrove.exchange/dev/protocol/technical-references/periphery-contracts) to get the gas price.

The role of the gas price updater bot is simply to push up-to-date gas prices to the oracle contract whenever the gas price changes significantly.
