Fees and income sources
The main source of income of a keeper is the task reward (provided by the task owner). Task reward is paid out in the native blockchain token, for example, ETH on Ethereum. Every time a keeper executes the transaction for a given task it receives the reward plus the gas compensation. The rewards are specified for each task individually.
Additionally, providers can offer incentives for task execution and provide arbitrary token reward for each task.
As described in the previous section, the gas is compensated based on the average gas price in the block where the transaсtion was included and mined. Thus, a keeper can both receive additional tokens (if the gas price it offered was lower than the block average, and the transaction was still executed), or loose (if it offered too high gas price, higher than the block average).
