This Tip is being proposed to Stakelink a fellow Thousand Validator member on Kusama.  He has developed a tool that can allow tasks to be executed based on substrate events an example of which is to execute staking reward payouts at the end of an era.  The convention at the moment is to execute a cron job every hour or 30 minutes to coincide with the end of an era.

This git repo can be found here: [https://github.com/stakelink/substrate-crond](https://github.com/stakelink/substrate-crond)

The developer has also mentioned that the tool can be extended based on any event found at [https://polkadot.js.org/docs/substrate/events](https://polkadot.js.org/docs/substrate/events) so those with specific use-cases can build upon it.
