feat: testing private events from Aztec.nr by benesjan · Pull Request #20640 · AztecProtocol/aztec-packages

Note: We will probably want to merge Serialize and Deserialize traits before merging this as it would make the diff smaller - waiting for response from Mitch to see whether it's a good time to do that change.

@nchamo LMK if you would not feel comfortable enough yet to review this. Can re-assing if that's the case.

+/// Returns up to `MAX_PRIVATE_EVENTS_PER_TXE_QUERY` private events of type `Event` that were emitted by
+/// `contract_address` and available in `scope`.


This is inaccurate as it is missing the fact that it only searches the last block. It also does not explain wtf scope is.

Somewhat addressed in 3361896

But I am not sure about this:

This is inaccurate as it is missing the fact that it only searches the last block.

Do you mean by that "up to last block"?

By searching only the last block I imagine events emitted in the last block. Or is your mental model here that "last block" contains any state that got accumulated by the chain up to that block?

I don't know the code of TXE enough to be sure here.

I may have been wrong when I wrote this, as it seems like the oracle does search from genesis all the way to the latest block.

Wraps the low-level oracle so users don't need to import and call the oracle directly. This provides a higher-level API consistent with the rest of TestEnvironment. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Short first paragraph, clarify that only last block is searched, explain what scope means (event recipient), mention self.emit, and point users to TestEnvironment method instead of using the oracle directly. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Move experimental warning to top of section as a note block. Use env.get_private_events instead of importing the oracle directly. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

@nventuro Re-requested a review here even though the PR is not yet finished as I need some clarifications - left the questions in unresolved discussions above.

Also please LMK if merging merge-train/fairies to this branch messed up the Github view of "changes since last review". If it messed it up I will wait with resolving conflicts for after the review finishes next time.

nventuro · 2026-03-31T20:02:34Z

I'd hold this off until we need it, given it's not high priority right now and would either go unused or subject users to API churn.
