Question on Arbitrum DAO treasury reporting: how do we ensure numbers are audit-consistent over time?

Hello Arbitrum community,

I’ve been following several recent and past Arbitrum DAO proposals involving treasury spend, service providers, and incentive programs, and I wanted to raise a practical question around financial consistency over time.

Arbitrum DAO executes transparently on-chain, but when treasury activity spans:

  • Multiple wallets and contracts

  • Long time horizons

  • Multiple token types

  • Changing price environments

it becomes surprisingly difficult to answer a simple question:

“What is the authoritative financial view of DAO spending at a given point in time?”

In practice, I’ve noticed that:

  • Different dashboards often report different USD totals

  • Recomputing historical spend months later can yield different numbers

  • The assumptions behind pricing, timing, and classification are rarely explicit

  • Reviewers and delegates sometimes rely on different data sources

This raises a few concrete questions I’d really appreciate input on:

  1. For delegates and reviewers:

    • When evaluating past spend, which source do you personally treat as “ground truth”?
  2. For service providers:

    • What financial reporting format have you actually been asked to deliver post-payment?
  3. For anyone involved in audits or compliance:

    • Where does reconciliation usually break or become time-consuming?

I’m not proposing any tooling or changes here — I’m trying to understand how the DAO currently handles financial ambiguity when multiple reasonable interpretations exist.

Any real-world experiences or opinions would be extremely valuable.

Thanks.
