You can input standard asset Id (as seen by pallet-assets) and as output you get H160 address of that asset.

## Account32Hash

For calculating `Account32Hash` ([here](https://github.com/paritytech/polkadot/blob/master/xcm/xcm-builder/src/location_conversion.rs#L25)), we provide a dedicated command. However, the possible `MultiLocation`s format is limited to:

1. `{ parents: 1, interior: X1(AccountId32{ network: Any, id: 0x<id>}) }`
2. `{ parents: 1, interior: X2(Parachain(para_id), AccountId32{ network: Any, id: 0x<id>}) }`

For the first case, use the following command:
```bash
xcm-tools account32-hash -a 0x84746218b9858233f45f99d742aa3ea2f31aeb5a525938f240fdee3000000000
5EKFVedcKtGBPytwgj9sbCTmjSr8wJTmhHuuWTz9RhMRrv1h
```
The value under `-a` is a SS58 public key.

For the second case, use the following command:
```bash
xcm-tools account32-hash -p 1000 -a 0x84746218b9858233f45f99d742aa3ea2f31aeb5a525938f240fdee3000000000

```
The value under `-p` is parachain Id, while `-a` is again public key.
