Thanks @ripcurlx, done! 👍

pazza83 · 2021-01-20T01:03:52Z

Hi @jmacxx thanks for this, much appreciated.

Please can you paste the text for https://user-images.githubusercontent.com/47253594/104983679-de267a80-59d2-11eb-9c2d-583bae1e73ac.png

So I can use the same info in the Wiki.

Many thanks

ghost · 2021-01-20T04:22:17Z

@pazza83

Trading using cash-by-mail (CBM) on Bisq requires that you understand the following:

BTC buyer should package cash in a tamper-evident cash bag.
BTC buyer should film or take high-resolution photos of the cash packaging process with the address & tracking number already affixed to packaging.
BTC buyer should send the cash package to the BTC seller with Delivery Confirmation and appropriate Insurance.
BTC seller should film the opening of the package, making sure that the tracking number provided by the sender is visible in the video.
Offer maker must state any special terms or conditions in the 'Additional Information' field of the payment account.
Offer taker agrees to the offer maker's terms and conditions by taking the offer.
MEDIATORS CANNOT MAKE JUDGEMENTS IN CBM DISPUTES. But they can help with smaller problems such as technical difficulties not related to scam attempts.

To be sure you fully understand the requirements of cash-by-mail trades, please see: [https://bisq.wiki/Cash_by_Mail]

If you do not understand these requirements, do not trade using CBM on Bisq.

ripcurlx · 2021-01-20T13:42:05Z

@m52go Could you please go over the new translations? Thanks!

ripcurlx · 2021-01-20T13:51:45Z

ACK from a functional perspective. Tried it on Regtest and everything seems to be working. But I want to wait for @m52go to proof-read the new translations before merging.

Small note on a carryover from before. Otherwise the main strings look good...I had edited them before already ;)

Yes, as far as I know @pazza83 is working on this one.

pazza83 · 2021-01-22T00:57:38Z

Yes going to get the wiki online this weekend.

pazza83 · 2021-01-22T01:34:19Z

Hi @jmacxx

Please see comment: https://bitcoinhackers.org/@pamaca/105594170227015360

I did initially think the role of the mediators would be the same with cash by mail as any other fiat payment. The mediators never really make a judgement, only a suggestion. It is the refund agent that makes the judgement when their suggestions are not accepted by at least one trader.

On the CBM issue there was some discussion about what the mediators would / would not be happy to mediate but no input was provided by the mediators to make a decision. Therefore, I think the dispute process should be the same as the other methods.

Therefore please can I suggest an edit to the second to last bullet point:

Change:

MEDIATORS CANNOT MAKE JUDGEMENTS IN CBM DISPUTES. But they can help with smaller problems such as technical difficulties not related to scam attempts.

to:

If there are any reasons dispute during the trade please initially try and resolve with your trade peer in Trader Chat. If you are unable to resolve in trade chat you can open up mediation where your mediator will be able to communicate with both traders and make a suggestion. If one party does not agree to the suggestion the trade will be arbitrated. For more information please see https://bisq.wiki/Dispute_resolution

huey735 · 2021-01-22T14:22:06Z

There seems to be an understanding that Mediators can cancel trades. I think that we should make an effor to point out that mediators can only point to Bisq's trade protocol and make suggestions.
Plus, hopefully, with your new tool @jmacxx and a guide written towards traders we could transfer a great deal of mediation to the traders themselves.

MwithM · 2021-01-22T16:41:35Z

I think that there is room for arbitration in this trades, even if it's small. Otherwise, indicating traders on how to proceed to payout and filming the unboxing doesn't makes much sense and should be all left in hands of particular terms set by maker.
Traders should know that it's very hard for mediators to find solid evidence in case of fraud and funds might get just sold and burned by burningman after being sent to DAO donation address if arbitration starts.

The lack of verifiable actions makes handling CBM disputes much harder. Mediators and arbitrators often won’t have a way to settle real disputes and decide payouts, but will help with technical issues.
Try to resolve disputes directly with your peer using trader chat. This is your most promising route to solving any CBM dispute.
If a trader rejects a mediation suggestion and opens arbitration, it could lead to lose both trading and deposit funds. Funds will be sent to a Bisq 'donation' address [HYPERLINK:https://bisq.wiki/Arbitration#Time-Locked_Payout_Transaction] and, if arbitrator doesn't find a proper payout, sold for BSQ by the burningman and burned.
Offer maker must state any special terms or conditions in the 'Additional Information' field of the payment account.
Offer taker agrees to the offer maker's terms and conditions by taking the offer.
BTC buyer should film or take high-resolution photos of the cash packaging process with the address & tracking number already affixed to packaging.
BTC buyer should send the cash package to the BTC seller with Delivery Confirmation and appropriate Insurance.
BTC seller should film the opening of the package, making sure that the tracking number provided by the sender is visible in the video.

I also move maker additional information to the top. I think it's more relevant.

pazza83 · 2021-01-22T22:52:16Z

I have based the following on @m52go's text and included @MwithM suggestions.

Trading using cash-by-mail (CBM) on Bisq requires that you understand the following:

BTC buyer should package cash in a tamper-evident cash bag.
BTC buyer should film or take high-resolution photos of the cash packaging process with the address & tracking number already affixed to packaging.
BTC buyer should send the cash package to the BTC seller with Delivery Confirmation and appropriate Insurance.
BTC seller should film the opening of the package, making sure that the tracking number provided by the sender is visible in the video.
Offer maker must state any special terms or conditions in the 'Additional Information' field of the payment account.
Offer taker agrees to the offer maker's terms and conditions by taking the offer.

CBM trades put the onus to act honestly squarely on both peers.

CBM trades have less verifiable actions than other fiat trades. This makes handling dispute much harder.
Try to resolve disputes directly with your peer using trader chat. This is your most promising route to solving any CBM dispute.
Mediators can consider your case and make a suggestion, but they are NOT guaranteed to help.
If a mediator is engaged, and if either peer rejects the mediator's suggestion, both peers' funds will be sent to a Bisq 'donation' address [HYPERLINK:https://bisq.wiki/Arbitration#Time-Locked_Payout_Transaction], and the trade will effectively be completed.
If a trader rejects a mediation suggestion and opens arbitration, it could lead to lose both trading and deposit funds.
Arbitrators will make a decision based on the evidence provided to them. Therefore, please follow and document the above processes to have evidence in case of dispute. For Cash by Mail trades the Arbitrators decision is final.
Reimbursement requests any lost funds resulting from Cash By Mail trades to the Bisq DAO will NOT be considered.
To be sure you fully understand the requirements of cash-by-mail trades, please see: [https://bisq.wiki/Cash_by_Mail]

If you do not understand these requirements, do not trade using CBM on Bisq.

ghost · 2021-01-23T03:29:15Z

@m52go
@pazza83 Looks like too much "wall of text". Also note last few lines got truncated.

By comparison here is @MwithM text. Still a lot but I like it better.

pazza83 · 2021-01-23T22:29:42Z

Hi @jmacxx

Ok, lets go with @MwithM's text.

I have added a holding page to the wiki that I will update this weekend.

https://bisq.wiki/Cash_by_Mail

pazza83 · 2021-01-23T22:42:23Z

Hi @jmacxx

Please can you let me know the following:

What is the security deposit amount. Is it set any differently from other payment methods?
Is the trade limit 0.25 BTC? This would be my recommendation.
I am assuming aging the same as other accounts that do not require signing?
I am assuming no account signing is required?
I am assuming CBM is available to all currencies. Will it be one currency per CBM payment account. This would be my recommendation.
What is the trade period? My recommendation would be 7 days.

Please can you post a screenshot of what CBM looks like at present when being set up in Bisq payment accounts.

I am assuming:

Account owner full name
Postal address
Currency

Jakub-CZ · 2021-01-23T22:53:58Z

@pazza83 As I'm in the middle of implementing your "wall of text", here's the screenshot:

There are only 7 currencies.
Trade period is 8 days.

Jakub-CZ · 2021-01-23T23:25:23Z

See PR #5110.
I went with the longer version. The unintended truncation is resolved.

pazza83 · 2021-01-24T00:01:22Z

Hi @Jakub-CZ

Is it possible to add for more currencies?

The big ones missing are:

CNY
JPY
KRW
BRL

It would be great though to not limit it and just let users select their local currency. Not sure the reason for the limitation?

Jakub-CZ · 2021-01-24T00:10:21Z

I guess so, but that question should be directed at @jmacxx or others.

I had nothing to do with this feature. I just wanted to translate the English texts initially, and only today I got dragged into this :)

pazza83 · 2021-01-24T00:13:43Z

Ok :)

@jmacxx please can you also let me know about #5092 (comment)

Many thanks

ghost · 2021-01-24T01:19:33Z

@pazza83

The big ones missing are:
CNY
JPY
KRW
BRL

I went with the list defined in Bisq known as MainFiatCurrencies.

public static List<FiatCurrency> getMainFiatCurrencies() {
    // Top traded currencies
    list.add(new FiatCurrency("USD"));
    list.add(new FiatCurrency("EUR"));
    list.add(new FiatCurrency("GBP"));
    list.add(new FiatCurrency("CAD"));
    list.add(new FiatCurrency("AUD"));
    list.add(new FiatCurrency("RUB"));
    list.add(new FiatCurrency("INR"));

I could add your 4 mentioned currencies to the list.

Or, if you prefer CashByMail to allow all fiat currencies I would change the checkbox grid layout into a combo box since it is a long list (156 currencies).

pazza83 · 2021-01-24T01:44:42Z

@jmacxx

Yes, I think all currencies would be best.

A combo box would be good. A better option would be something that just lets the user select one currency. Would the same setup as used on National Bank Transfer be possible (Select continent > select country)?

pazza83 · 2021-01-25T01:15:54Z

Hi the first draft of the Cash by Mail Wiki for Bisq is online

Please share your thoughts.

I am wondering if phone number should also be included at the payment account creation stage so that this can be passed on the the courier. Would Sellers of BTC using cash by mail be happy to share their phone number with the buyer / courier company to facilitate a smooth delivery?

m52go · 2021-01-25T17:29:28Z

@jmacxx @chimp1984 I don't understand the "contact information such as name or nym" field.

If the goal is to have a name for the mailing address, it could be specified in the postal address field.

Is it intended as a backup means to get in touch, in case trader chat doesn't work? Or is there another reason?

ghost · 2021-01-25T18:56:09Z

Hi @m52go. Yes I suppose it could have been just an address field. It is more common to separate name from address though. The user could put anything into the name/nym field and I was trying to highlight that freedom by explicitly mentioning "Nym".

If there are strong reasons for not having that field, let me know, I can remove it.

pazza83 · 2021-01-25T19:14:17Z

I agree with adding the name field. Whilst it could be added in the address field, if a user completed without a name, it could decrease the chances of a successful delivery.

m52go · 2021-01-25T19:14:50Z

No worries...I was testing it on regtest while editing documentation and was just confused by it.

I suggest one of the following.

Keep the field, make it optional, and change text to "Name or nym envelope should be addressed to (optional)"
Remove the field and change postal address field text to "Postal address (include name or nym package should be addressed to, if desired)"

Maybe (1) would be better if it increases chance of delivery.

m52go · 2021-01-25T19:16:20Z

Or if it's better not to be optional, that's fine too. I just think specifying that the purpose of the name is for addressing the envelope is important.

EDIT: in this case, text in suggestion 1 above could become:

"Name or nym envelope should be addressed to"
