How do i find the address of the treasury?

Question

I have implemented pallet_treasury just like Kusama, how do i find the resulting address?

Answer 1

Find the pallet id in runtime first. Different networks might use different id. Kusama treasury pallet id

Use subalfred.

λ subalfred key 'py/trsry' --key-type pallet --network kusama
public-key 0x6d6f646c70792f74727372790000000000000000000000000000000000000000 PalletId(py/trsry)
kusama F3opxRbN5ZbjJNU511Kj2TLuzFcDq9BGduA9TgiECafpg29

Answer 2

import { stringToU8a } from '@polkadot/util';
import { encodeAddress } from '@polkadot/util-crypto';

const treasuryAddress = encodeAddress(stringToU8a("modlpy/trsry".padEnd(32, '\0')))

Answer 3

Here's another using just subkey:

$ HEX=$(printf "modlpy/trsry" | xxd -p)
$ PUBLIC_KEY=$(printf 0x%-64s $HEX | tr " " 0)
$ subkey inspect $PUBLIC_KEY --network kusama --public
Network ID/Version: kusama
  Public key (hex):   0x6d6f646c70792f74727372790000000000000000000000000000000000000000
  Account ID:         0x6d6f646c70792f74727372790000000000000000000000000000000000000000
  Public key (SS58):  F3opxRbN5ZbjJNU511Kj2TLuzFcDq9BGduA9TgiECafpg29
  SS58 Address:       F3opxRbN5ZbjJNU511Kj2TLuzFcDq9BGduA9TgiECafpg29
