## Deploy
Check config.js for actual values.
With `salt` = `0x0000000000000000000000000000000000000000000000000000000047941987` addresses must be:
1. `L1Unwrapper` - `0x3F615bA21Bc6Cc5D4a6D798c5950cc5c42937fbd`
2. `TornadoPool` - `0x0CDD3705aF7979fBe80A64288Ebf8A9Fe1151cE1`
Check addresses with current config:
```shell
yarn compile
node -e 'require("./src/0_generateAddresses").generateWithLog()'
```
Deploy L1Unwrapper:
```shell
npx hardhat run scripts/deployL1Unwrapper.js --network mainnet
```
Deploy TornadoPool Upgrade:
```shell
npx hardhat run scripts/deployTornadoUpgrade.js --network xdai
```
