# Quick start

In our example, we covered these steps:

1. Emit event on the [Mainnet](https://etherscan.io/tx/0x9f89aae86d1b69cf63065bfc9f30478b6dc613b4655a857bc115a1275604b88c) chain 
2. Get proof of the event from the Signer
3. Receive event on the [Polygon](https://polygonscan.com/tx/0x3b9c04a4d3d0061173be7654724a9114441f125bc5912a4b31e9bb3f39b4223c) chain
