```

* [`sv3dd-oaaaa-aaaar-qacoa-cai`](https://dashboard.internetcomputer.org/canister/sv3dd-oaaaa-aaaar-qacoa-cai) is the ckETH minter canister.
* The fee collector is the 0000000000000000000000000000000000000000000000000000000000000fee subaccount of the minter canister.
* The transfer fee is 2_000_000_000_000, which is around 0.004 USD, roughly in the same bullpark as ckBTC transfer fees of 10 satoshi.
* We enable the ICRC-2 support because it's required for the ETH withdrawal flow.
