How to Determine the SNS Treasury Token Balance?

Governance SNS Project Governance

Hello everyone,

I’m working on gathering information about SNS treasury tokens for various projects, and I’ve encountered a challenge I hope to get some guidance on.

My specific example involves the OpenChat project.

Goal:

I aim to identify how many tokens are in the SNS treasury.
For ICP, this process is straightforward:

  1. Go to the SNS page: ICP SNS Dashboard
  2. Locate the governance canister in the “Canisters” section: Governance Canister
  3. Derive its wallet address using the command:
    dfx ledger account-id --of-principal 2jvtu-yqaaa-aaaaq-aaama-cai
    This produces:
    a2200978cf15fa0d19b7c7eb75cc5d6d3ebabbacaec64a2a9a3f811277619c57
  4. Search for that account on the dashboard: Account Info

For the CHAT token ledger, I tried to follow a similar process. However, while the CHAT ledger balance shows 0, I noticed that funds are instead located in a subaccount: Subaccount Example

Question

What is the best way to derive and access this subaccount on-chain to confirm the treasury balance?

For context, I’m part of the ICPTokens team, and we are working to aggregate and calculate SNS token supplies.

Specifically:
Circulating Supply = Total Supply - Treasury Balance

We also aim to display what percentage of circulating tokens are locked in neurons.

Any advice or best practices would be greatly appreciated!

This is how the subaccount is calculated - ic/rs/nervous_system/common/src/ledger.rs at fd5c4949944cde2a7301449b84df2acb4211e618 · dfinity/ic · GitHub
