Keeper Jobs

Suggest Edits

Keeper jobs occasionally poll a smart contract method that expresses whether something in the contract is ready for some on-chain action to be performed. When it's ready, the job executes that on-chain action. Examples:

  • Liquidations
  • Rebalancing portfolios
  • Rebase token supply adjustments
