# RAIRsync {% hint style="info" %} All of the configurations for RAIRsync are located in the RAIRnode env setup. Basically don't touch this repo unless you want to modify or extend it to other providers. {% endhint %} Configurations for RAIRsync are located in environment variables as well as hardcoded into the database. By running the database install script, you can auto configure a working system. By default we specify block numbers to start syncing at 4/30/2024. ## ENVS In RAIRnode these [2 environment variables](https://docs.rairprotocol.org/rairprotocol/codebase/rairdapp/rairnode/backend-variables-library#long-term-sync) specify the main syncing settings. ```yaml sync_contract_repeat_every = {minutes} ``` Type - Int Sets time intervals for the syncing of smart contracts. Only for data that changes onchain. Time between end of sync task and next time it starts. ```yaml sync_contract_task_interval = {minutes} ``` Type - Int Sets time intervals for the syncing of smart contracts. Only for data that changes onchain. Time between start of one sync and the next. Waits between blockch ## Database Specify which block number to begin syncing at by blockchain. This feature is currently hardcoded into the MongoDB.
