@OriolMunoz-da please check if these changes (and further below in this file) are OK, (ignoring noHoldingFeesOnTransfers) otherwise I have to keep getTotalAmuletBalance around in the store, but I would prefer to just delete more.

noHoldingFeesOnTransfers.supported is true for all networks now, so you shouldn't need the fallback
the issue is in tests though, because it depends on the latest ACS snapshot which might not be available (as it's computed every 3h)

+              .flatMap(_.totalSupply)
+              .valueOrFail("total balance not yet defined")


for example here, how do you know that a snapshot was generated?
(maybe there's a forceSnapshot somewhere that I'm not seeing)

always forcing now in getTotalAmuletBalance in ScanAppReference

Lgtm minus the comments Oriol already made, thank you!

I assume we already discussed this with product (probably while I was out), if not let's ofc do that so noone gets surprised by it.

-                sum_cumulative_change_to_initial_amount_as_of_round_zero -


we should also be able to cleanup the dbs and txlog parsers further, perhaps in multiple steps:

make the columns here and in the scan txlog only required for the balances nullable

stop writing those fields

eventually nuke those columns

I'd suggest to move this to separate PRs but let's make sure we push through at least 1 and 2 as it meaningfully simplifies the code.

Good idea, thanks

I'll add another PR follow up for this.

Added #3563 for leftovers

I'll do this later though, rather first see what more can be removed and then simply do it all at once.

+    - ``/v0/total-amulet-balance`` and ``/v0/wallet-balance`` endpoints have been removed.


I suggest mentioning the replacement endpoints here and also mention that the existing endpoints are already deprecated. "deprecated endpoints have been removed in favor of X" just sounds much nicer than "Y has been removed"

ray-roestenburg-da · 2026-01-15T11:16:17Z

Also removed wallet-balance usage in scan_txlog.py and everything that was using it (removed option --scan-balance-assertions)

ray-roestenburg-da · 2026-01-15T12:54:58Z

FYI I will not merge this until I get OK from Product (we have discussed before, but to be certain)

thanks!

any reason not to make this an error instead of an optional? it seems like we really always expect amulet to be present

yeah can do that, it's only used for testing now anyway

nit: read this from whatever config we have for this instead of hardcoding the string

not sure I understand why this changed now but it does seem correct 🤷

I also don't know, I did a npmFix and npmLint at some point..
