04:24:09 <willyijinin[m]> After I sent a transaction, the view-only wallet can view incoming and outgoing transactions, can anyone explain why?
04:26:04 <selsta> View only wallets can't see outgoing transactions, they can only see change as incoming transaction.

04:43:08 <willyijinin[m]> I sent a transaction using view-only wallet rpc and offline wallet. Then I query my view-wallet-rpc and the balance includes outgoing txns.
04:43:08 <willyijinin[m]> But I find the screenshot more convincing. I have imported the view-only wallet onto my monero GUI and it also shows all the outgoing transactions and the correct balance that counts both incoming and outgoing transactions.
04:45:21 <entry1[m]> How can you send a transaction using a view-only wallet/key? Are you sure its not a hot wallet?
04:46:07 <willyijinin[m]> entry1: https://github.com/monero-ecosystem/monero-javascript/blob/master/docs/developer_guide/view_only_offline.md
04:46:07 <willyijinin[m]> This doc explain how with a combination of view-only wallet + offline wallet.
04:46:40 <selsta> willyijinin[m]: what is your exact question now?
04:47:04 <selsta> if you export/import outputs and key images you can see outgoing tx
04:47:13 <willyijinin[m]> Ok then.
04:47:15 <selsta> but if you just have a view key you can't
04:47:20 <entry1[m]> But you always need the private key to send funds, correct? How is it a true view-only wallet if you sent a transaction
04:47:53 <willyijinin[m]> @entry1 Please check the doc.
04:47:55 <selsta> entry1[m]: you sign the transaction from an offline wallet
04:48:16 <selsta> which has the private spend key
04:49:40 <willyijinin[m]> selsta: I understand you now. But this question derives from a more difficult issue. Please see this github issue:
04:49:40 <willyijinin[m]> https://github.com/monero-ecosystem/monero-javascript/issues/71
04:49:40 <willyijinin[m]> Do you know why?
04:52:29 <selsta> willyijinin[m]: can you try to add exportOutputs(true), same for exportKeyImages(true)
04:52:48 <willyijinin[m]> selsta: Why?
04:52:58 <selsta> so that it exports all outputs and key images
04:53:05 <selsta> otherwise it only exports new ones
04:53:59 <selsta> (assuming it defaults to false, which I don't know about this library, but it's worth a try)
04:56:46 <willyijinin[m]> selsta: It works but why exports all outputs and key images works? And if it works why the library defaults to only export new ones? woodser 
04:57:16 <selsta> it's just how it's done in monero code
04:57:31 <selsta> don't know the exact reason for it
04:58:55 <willyijinin[m]> selsta: Thank you very much.
04:59:19 <selsta> willyijinin[m]: https://github.com/monero-project/monero/blob/master/src/wallet/wallet2.h#L1384
04:59:33 <selsta> `bool all` defaults to `false`
05:00:12 <willyijinin[m]> Do you happen to know the answer to this question?
05:00:16 <willyijinin[m]> I call this `const result = MoneroUtils.validateAddress(address, net);`... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/2fa40dd3e1d100e9c4eb43913ff21a39458b51be)
05:00:43 <willyijinin[m]> selsta: 
05:01:23 <selsta> need to see your full code
05:02:36 <willyijinin[m]> This is my full code:... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/b30ad0b0df44e7ad80a903925ad1a2a2a6c764c5)
05:04:52 <selsta> nothing obvious, woodser might know
05:07:01 <willyijinin[m]> selsta: 
05:07:01 <willyijinin[m]> https://github.com/monero-ecosystem/monero-javascript/blob/master/docs/developer_guide/view_only_offline.md
05:07:01 <willyijinin[m]> In the doc, the view-only wallet exports the outputsHex to the offline wallet, and then the offline wallet immediately exports the keyImage to the view-only wallet?
05:07:01 <willyijinin[m]> I thought the "Related one-time private key x(keyImage) is specific to unspent output." Since I haven't specified the amount yet, how does the offline wallet know which output is being used next, and bond to the Keyimage?
07:20:19 <willyijinin[m]> Also, I don't understand why offline wallet need to export keyImages to view-only wallet, and then let view-only wallet to create a transaction, then export unsignedTx back to the offline wallet to sign? Can't offline wallet create the transaction and sign it since it already has the keyImages?
08:10:01 <kayabaNerve> willyijinin[m]: Key images solely specify the TX used as an input (as a ZKP). It doesn't have the private key needed to generate the proofs on destinations/amount out.
08:10:57 <kayabaNerve> I'm not overtly familiar with the exact process. IIRC the TX hash is signed as part of CLSAGs which is the ring signatures proving the key image's legitimacy and I couldn't comment on how the private key is used in relation to amounts out (if it is).
08:11:05 <kayabaNerve> But I can comment on why it's like this. Auditability
08:11:50 <kayabaNerve> If you have a charity which receives funds, and wants to prove it's not embezzling them, it needs to provide all key images (and ring signatures accordingly for a ring of 1). Then, checking if funds have been spent is as simple as checking for presence on the blockchain
08:12:08 <kayabaNerve> But if you published key images and they were sufficient... your charity just got robbed.
08:12:59 <kayabaNerve> ... wait, I may have misread this question. I'm sorry. I think I still answered the surrounding context though
08:13:34 <kayabaNerve> Offline wallets knows key images. Offline wallet doesn't know what's on the blockchain. View-only wallet does know what's on the blockchain. It can specify which inputs to use accordingly to prevent double spend attempts.
08:13:47 <kayabaNerve> Sorry for misunderstanding your question initially. Hope that helps
12:17:02 <jetsteel[m]> will.yijinin: for each transaction you recieve, there is an associated key image that can *only* be calculated if you have the private key.... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/382fd25bb617a3612adfdd1ad667655ad918d6b8)
12:21:33 <jetsteel[m]> will.yijinin: sorry for wall of text.
12:21:33 <jetsteel[m]> It was formatted before I sent it.
12:21:33 <jetsteel[m]> :/
12:24:29 <moneromooo> (each output, for clarity)
12:27:02 <hyc> ^right. for each output received, not for each txn received
12:28:11 <woodser[m]> will.yijinin: you need to call `await LibraryUtils.loadKeysModule()` before using `MoneroUtils.validateAddress()` so the wasm is ready to be used for synchronous utilities
13:15:26 <willyijinin[m]> jetsteel: woodser Do you happen to have java sdk or js sdk to decode the transaction with privateViewKey?
13:19:08 <willyijinin[m]> Actually get the address from the `vout.key` from the transaction, what the view wallet is doing.
