Multiple currencies are suported, these are:

• EUR

From what I can see only EUR and BRL are the ones that are able to be withdrawn / deposited to and from a fiat account via SEPA or TED (Express Wire Transfer).

USD and GBP can be added in the app by exchanging other currencies / cryptos.

Stable coins; BUSD, USDT, USDC and DAI can also be deposited and used to send / receive payments.

How payments are made

Transfers take place using CapCodes. CapCodes are like coupon codes you can generate at any time and use it to transfer funds

CapCodes are an electronic cheque system that makes it possible to store amounts of money, precious metals or cryupto-currencies in a short code, easy to be written down, that can be written in a piece of paper to make transactions even when you are not connected to the internet.

When you generate a CapCode, you get a voucher (coupon code) that you must take note (don’t worry: it’s always possible to recover a CapCode that you have lost!). Such code stores funds in any of the currencies supported by Capitual, and you can share it with someone else, allowing the payment in any of these currencies. It’s needed to have a Capitual account to redeem a CapCode.

After generating a CapCode, the amount gets “locked in”, and is already deducted from your balance. If you have given up or will no longer need to use the CapCode, you can redeem it yourself, onto your own account. It’s also possible to track, from your account, whether a CapCode has already been redeemed.

For while, CapCodes are only available when accessing your account using a computer.

Payment amounts

Unconfirmed accounts have a fixed transfer limit of US$ 9,999.00. As this limit is reached, the account must be confirmed for continued usage.

Here is the XD for Capitual, this should be straight forward to add:

[BtcContributor]

@pazza83 I started working on this.

Two questions:

1. Are there any specific limitations / constraints for CAP account number? So that I can implement proper checks and validators
2. Not sure which is the correct Per-trade limit to set (See https://docs.bisq.network/payment-methods#supported-fiat-payment-methods) so to put correct limitations in Limitations field (see UI above).

Thanks!

[pazza83]

Hi @BtcContributor that is great news.

1. The CAP code number is as follows: CAP-XXXXXX (where XXXXXX are any 6 alphanumeric characters), therefore you can start with CAP- and leave the user to fill in the 6 alphanumeric characters.
2. 0.25 BTC buy and sell no signing required. 1 day trade window.

[BtcContributor]

Thanks @pazza83

I was asking question 2 as you wrote that there is a low risk of chargeback and fraud but you are saying that the trade limit is 0.25BTC that is used for high risk payment methods.

[pazza83]

Hi @BtcContributor

0.25 BTC is used for low risk payment methods.

Generally fiat payment methods do not go above 0.25 BTC

[BtcContributor]

Ok @pazza83 thanks for the clarification!

[BtcContributor]

Hi @pazza83, implementation is almost completed.

Could you please tell me which are the exact words you want as Info when adding this new payment account?

For example, when you try to add a Revolut account you see this:

You can find other examples here and near that: https://github.com/bisq-network/bisq/blob/master/core/src/main/resources/i18n/displayStrings.properties#L3458

Also the messages in various steps of buying and selling for both buyer and seller are needed.
See for example this: https://github.com/bisq-network/bisq/blob/master/core/src/main/resources/i18n/displayStrings.properties#L660

My advise is to check with other payment accounts what is needed for each trade step and then choose a text accordingly.

Maybe @m52go could help you.

This info should be provided for all other new payments method to add.

Thanks!

[pazza83]

Hi @BtcContributor many thanks I have taken a look.

I think Capitual can be done with using the default messages. Seems that is what is used for most trades?

portfolio.pending.step1.info=Deposit transaction has been published.\n{0} need to wait for at least one blockchain confirmation before starting the payment.

portfolio.pending.step2_buyer.pay=Please pay {0} via the specified payment method to the BTC seller. You''ll find the seller's account details on the next screen.\n\n

portfolio.pending.step2_seller.waitPayment.headline=Wait for payment

portfolio.pending.step2_seller.waitPayment.msg=The deposit transaction has at least one blockchain confirmation.\nYou need to wait until the BTC buyer starts the {0} payment.

With regards the information tag I am not sure when this appears in the process. I am assuming when something has changed from one Bisq version to another?

@m52go please can you let me know if you have a template you would like me to use for the text to add the payment methods. I have not completed any in app text before. Also it would be good to know what the text defaults too if nothing is entered.

Many thanks

[BtcContributor]

Hi @pazza83, as for the info message you can find that when you a add a new payment account.
Try to add a Revolut account and you will see where appears the screenshot in my previous post.

Once I have the final text, I can release the final code for Capital.

[m52go]

I'm working with pazza83 to figure out this text -- my fault for missing this exchange earlier.

There's no template yet, but I think it would be a good idea to establish some kind of general spec to make implementing new payment methods straightforward for any developer.

[pazza83]

Hi @m52go

I am scratching my head a bit with this task!!

Here is the reference file I am using:
https://github.com/bisq-network/bisq/blob/master/core/src/main/resources/i18n/displayStrings.properties

I think the custom strings for a 'NEW-PAYMENT-METHOD' that need to be defined by the payment maintainer are as follows:

portfolio.pending.step2_buyer.NEW-PAYMENT-METHOD=Please pay {0} to the BTC seller by using NEW-PAYMENT-METHOD (include any things to for buyer to be aware of)

portfolio.pending.step3_seller.NEW-PAYMENT-METHOD=The buyer has to sent you.... please check.... Only confirm receipt after you have received the funds. (include any things to for the seller to be aware of)

payment.NEW-PAYMENT-METHOD.info=Include any special instructions for the payment method that both buyer and seller might need to be aware of.

Additional custom fields for the fields themselves but I think these will all be self explanatory (based on field names as shown in graphic examples) and can be added by the devs?

Let me know your thoughts.
