- [The Scroll Messenger — Docs](https://docs.scroll.io/en/developers/l1-and-l2-bridging/the-scroll-messenger/)
- [Transaction Fees on Scroll — Docs](https://docs.scroll.io/en/developers/transaction-fees-on-scroll/)
- [L1ScrollMessenger.sol — GitHub](https://github.com/scroll-tech/scroll/blob/develop/contracts/src/L1/L1ScrollMessenger.sol)

## Deployment
1. Deploy the ISM

```sh
forge script script/Deploy.s.sol:DeployHook --rpc-url sepolia --broadcast -vvvv
```
3. Set the authorized hook
> Note: you need to set both the ISM address and the hook address in the script
