## How to integrate [RedStone Push](https://docs.redstone.finance/docs/dapps/redstone-push/)?

The RedStone Push model ensures that data is pushed into onchain storage via a relayer. Dedicated to protocols designed for the traditional Push Oracles model, that want to have full control of the data source and update conditions (heartbeat and deviation threshold).
Push model is available on both TAC Testnet & Mainnet.

## How to integrate [RedStone Pull](https://docs.redstone.finance/docs/dapps/redstone-pull/)?

The RedStone Pull model allows your dApp to utilize data feeds delivered “on-demand”, only when the data is needed. Thanks to the implementation of the EVM-connector library and extending your Ethers.js, your dApp will be able to attach signed data packages with timestamps to call data of your users’ transactions.

Please see the specific steps and ready code samples in the [Docs](https://docs.redstone.finance/docs/introduction).
