0011340: instance names are case-sensitive!

Wed, 08 Apr 2026 14:07:12 +0200

But (at least) in the taler://pay-template/ case, I see the WebExtension wallet silently convert the instance name to lower-case. As a result, the merchant backend then doesn't find the instance and the payment does not work.

Please fix wallet-core (and possibly UIs!) to ensure instance names are treated as case-sensitive!

0010017: enable automatic monthly transfer to wallet via periodic transfer

Wed, 08 Apr 2026 12:46:21 +0200

We've had this request now from a customer in CH as well as from BEKI: They are used to doing automated periodic monthly wire transfers and would like them to automatically withdraw money into a Taler wallet. We should support this.

Note: requires also some exchange changes, as right now reserve public keys come with a UNIQUE constraint...

0011160: libeufin-* users fail to be added during installation on ubuntu 24.04 LTS

Wed, 08 Apr 2026 12:45:08 +0200

Ubuntu 24.04 (current LTS) ships systemd-sysuser version 255, but the modifier used in the ubuntu packages is only supported starting from version 257: https://www.freedesktop.org/software/systemd/man/latest/sysusers.d.html#u

Applies to both libeufin-bank and libeufin-nexus.

This is reported as an error in setup.log, but does not stop the regional currency deployment script, which it should probably do.

Intermediate solution is to edit /usr/lib/sysusers.d/libeufin-*.conf to remove the exlamation mark, then run `systemd-sysusers`.

Actual solution will
1. taler-deployment: fail regional-currency installation on error reported by postinstall of .deb package
2. libeufin-* use "u" instead of "u!" in the config files.

0010545: add error code in merchant spec

Mon, 06 Apr 2026 19:45:59 +0200

In order to handle failure gracefully.

Right now we are only showing the hint that comes from the server which is not good for end users. Maybe good for admins.

We need the same that we did on libeufin: all the possible error codes must be on the spec. Any code returned by the server that is not part of the spec will fall back to the present behavior which shows a generic error and the hint from the server.

With this enumeration the client must cover this path with a meaningful error with i18n or event create special ui to handle the failure better.

For example:

$ curl 'http://merchant.taler.test/private/orders' -H 'Authorization: Bearer secret-token:CEQDN7P9217ZWEDG46PKFKXGXMVY3P6VFFJX6ZCYNFG2SXETF3N0' --data-raw '{"order":{"amount":"KUDOS:2","summary":"w","products":[],"pay_deadline":{"t_s":1762289268},"wire_transfer_deadline":{"t_s":1762454868},"refund_deadline":{"t_s":1762454868}},"inventory_products":[],"create_token":true}'
{
"code": 2500,
"hint": "The merchant instance has no active bank accounts configured. However, at least one bank account must be available to create new orders."
}

0011231: Merchant: Some beta-test cases need to be replayed to (maybe) reproduce money losses in relation to bank transfers

Sat, 04 Apr 2026 08:49:04 +0200

A beta tester could replay (after some successful transfers) the following unsuccessful transactions:
1. Bank transfer with minimal amounts for verification of the bank account before a deposit could be effectuated (Taler Wallet -> bank account). The transfer of CHF 0.01 from the bank account takes the same amount of time as a transfer bank account -> Taler Wallet (which is to be expected). But the CHF 0.01 from the bank account did not arrive anywhere, neither in the Taler Wallet nor back in the user's bank account. This was tested with Alpian Bank and PostFinance.

2. The KYC process needed to be performed over and over again for every deposit Taler Wallet -> bank
"I would expect to have to make exactly one transfer from a bank account to a wallet and then always be able to send money back. However, depending on the bank, it seems that KYC is required again when sending money back. It also seems that KYC expires after a few days and has to be done again."

3. Bank -> Taler Wallet with transfer amount too small, money arrives but flagged as "fee"
"If you create a transfer in the Taler Wallet for, say, CHF 10.00, but the transfer from the bank is only for CHF 5.00, CHF 5.00 will arrive in the wallet and CHF 5.00 will be listed as a “fee.” Basically, this works OK, but the naming is a bit strange."

4. Bank -> Taler Wallet with transfer amount too high --> money gets lost??
"If you create a transfer in the Taler Wallet for CHF 10.00, for example, but the bank transfers CHF 15.00, CHF 10.00 will arrive in the wallet. The extra CHF 5.00 will remain missing and will not be transferred back."

0011307: copy+past of partial 2FA code doesn't work

Fri, 03 Apr 2026 17:04:18 +0200

The user thus can't paste the two blocks separately, which is confusing / counter-intuitive.

0011321: When changing settings, e.g., cut-off dates, browser jumps to /webui/#/orders

Fri, 03 Apr 2026 16:27:14 +0200

When changing settings, e.g., at a location like here

$site/webui/#/settings

after confirming the changes, UI loads

$site/webui/#/orders

0011333: Not possible to upload logo

Tried to upload logo to my.taler-ops.ch, get error, see attachment. Also logo in attachment

0011336: Weird behavior during adding the products

Fri, 03 Apr 2026 01:48:35 +0200

and then not possible to do anything anymore

0010755: write design document for self-provisioning page

Fri, 03 Apr 2026 00:03:35 +0200

We're flipping back and forth between different terminology, so we should document our decisions (and rejected alternatives) in a short design document.

0011272: wallet should provide flag to enable simple/deterministic coin selection [2h]

Fri, 03 Apr 2026 00:01:37 +0200

0009315: need tests for auditor KYC support [2d]

Fri, 03 Apr 2026 00:01:22 +0200

The src/auditor/test-kyc.sh is a starting point, but inadequate.

0011179: anastasis regression: test suite hangs

Thu, 02 Apr 2026 23:56:58 +0200

Seems something to do with "Running wallet run-until-done...", maybe some taler-harness API change? Please check.

0011338: doesnt cancel request when changing tabs

Thu, 02 Apr 2026 23:53:14 +0200

this leads to sometime show incorrect information on the order list page

0009433: auditor database garbage collection not implemented

We also need to figure out what that would even mean ;-).

0011213: In email auth code user "admin" is (always?) shown as login name

Thu, 02 Apr 2026 22:55:40 +0200

I see this the first time (introduced in taler-merchant v1.5.0?):

1.
Not sure if the login line in the email should even be showed, but in any case it's not admin; I used "mechant1_5_0" as username.

2.
Confusion login vs. username should also be avoided; if this line should stay, then I'd suggest to say username.

0011318: reserve open coin signature not over sufficient fields?

Thu, 02 Apr 2026 17:57:57 +0200

Currently, TALER_wallet_reserve_open_deposit_sign() does not sign over h_denom_pub, h_age_commitment *or* even the amount. This seems wrong.

0011052: exchange does not show global fees when no wire fee is configured

Thu, 02 Apr 2026 17:56:54 +0200

On the cyclos test exchange, I uploaded global fees, because I saw they're missing.

However, until wire fees are also uploaded via taler-exchange-offline, the global fees are shown as empty.

That's confusing / there is no warning or other kind of indication that something is wrong.

0010491: merchant backend should allow import/export/migration [meta] [14d]

0010995: cannot withdraw, wrong exchange

Thu, 02 Apr 2026 17:55:39 +0200

I have a wallet with TOPS-CHF. I am scanning a QR code with BFH-CHF. The BFH CHF exchange was not previously on this phone. I get an error "unexpected exception (message: Exchange https://exchange.taler-ops.ch/ is not usable for withdrwal, as account payto://iban/sandbboxx/DE... is not acceptable to the exchange". Alas, that's NOT the exchange the QR code I am scanning is referring to!

0011335: Review of strings on the settings page in the Merchant Backoffice UI

Thu, 02 Apr 2026 13:58:08 +0200

On the settings page in the Merchant Backoffice UI, a request for change makes sense: "Zahlungsdetails" --> "Zahlungsfrist" (in English: "Payment delay"). This is easy to do. Tested was v1.5.3 with instance talerstickers together with HM.

Moreover, the whole page needs a new feature in relation to the addition of time delays (under the scroll-down menu "Default cut-off times"): I suggest to insert plus symbols between the specific time delays (t.i. payment delay, refund delay, wire transfer delay) to clarify that these times are added to a period of time between payments and wire transfers that end up on the bank account (which is what merchants want to know in the first place).

After having reviewed the German strings in question this ticket will be then forwarded to the person in charge of the UI designs (t.i. contemporarily Vlada).
