I have added to the OP the steps for exporting and importing labels using Nunchuk Wallet. This software supports both the BIP-329 standard but also has a native export format.

* Nunchuk Wallet
Supports exporting labels: YES

Nunchuk supports exporting and importing labels in Nunchuk's export format or as JSON files according to the BIP-329 standard.

How to export labels with Nunchuk Wallet:

1. Open your wallet from the home screen.
2. Click on "View wallet config."
3. Click on the three dots in the upper right corner.
4. Click on "Export labels."
5. Select either the Nunchuk or BIP329 export format.
6. Enter the location where to save the .json file.

How to import labels with Nunchuk Wallet:

1. Open your wallet from the home screen.
2. Click on "View wallet config."
3. Click on the three dots in the upper right corner.
4. Click on "Import labels."
5. Select either the Nunchuk or BIP329 import format.
6. Find the location where you saved the .json file and import it.

Meanwhile, Chelsea defeated Paris Saint-Germain 3-0, unexpectedly. If Razed were to produce any statistics on this, I'm sure many people would have bet on Paris Saint-Germain.
And I would have been one of them. After the tournament PSG had played so far and the big names they had defeated, it was really unexpected to see them demolished like that in the Finals. Chelsea was incredibly efficient, turning their big chances into goals and defending nicely against PSGs attacking force. The result seems a bit too harsh. It really wasn't PSGs day. Maybe seeing the Orange Man made them nervous.

Re: Why smartcards are the future of seed backups - Ledger R. Key vs Seedkeeper

I think this is highly unlikely. If it were possible, it would imply that other wallet manufacturers have left open access to SEEDs on devices they've produced, which would be serious security flaw. As I’ve mentioned in one of my previous post somewhere here on forum, SEED must be backed up only once, right after it's generated. Whether the backup is done via NFC to smart card or through another secure method, SEED must then be sealed inside SE and never exposed again.
But we know that's not the case. If anyone had any doubts if sensitive data can be retrieved from secure element chips used in hardware wallets, those doubts should now be gone after we saw what is possible with Ledger Recover. Keys can be retrieved, copied, divided in shards, and sent over the internet to third parties. All that's needed is the right code to enable it. The question now is who will be crazy or stupid enough to officially follow in Ledger's footsteps?

I wanted to say the same thing hugeblack did. Splash is relatively new so it might not yet be on the radars of blockchain analysis firms and other enemies of privacy. Still, knowing which CEXs don't give the crypto that comes from Splash a negative rating and bad AML score is a valuable piece of information. @splash does that sound doable to you?

Also, will you consider adding other stablecoins to your platform besides DAI?

Re: Why smartcards are the future of seed backups - Ledger R. Key vs Seedkeeper

I believe this is because both Flex and Stax support NFC, as the backup method used by Ledger requires such communication channel. I’m sure if their other products supported NFC, they would also extend this backup to those devices.
That's true for the current range of available Ledger hardware wallets. But if the company wanted to, they could have developed Ledger Recovery key to be compatible with hardware wallets from other brands as well. I am not sure how many such devices that are equipped with NFC chips are out there. I think Cypherock is one of them and the Tangem Ring. I think OneKey communicates through NFC also.

The point I was trying to make in my previous post is that there is a purpose behind their decision to only support Ledger hardware. They want you to buy their devices if you want to use Ledger Recovery Key and vice versa.

I noticed something while playing around the exchange fields.
If you enter the coin information (From?, To?, Amount?, etc.), the exchange will show you the rates in the output info on the bottom left. However, if I switch from dynamic to fixed rate or vice versa, the exchange only shows the current exchange rate between the two selected pairs. It doesn't display the new amount the user will get. I would have to fill in an amount under the "Amount" field again. I think it would be better if the correct amounts are shown immediately after changing the rates.

Is BFG still only listed on dex? Because the last I knew BFG was listed on Biswap, but I have no idea if there are any CEX platforms that list it? It seems like there aren't any yet despite
Based on the information available on CoinMarketCap, the BFG token only trades on PancakeSwap and Biswap. The token has made a decent little pump in the last 7 days and is up almost 30% in that period.

Keep in mind that popular CEXs only list cryptocurrencies that have big trading volumes because they want to make money from trading and withdrawal fees. Tokens with low trading volumes basically have no chance to be listed. They could be listed on small CEXs but the numbers there are insignificant anyway.

Re: [New offer] Buy Trezor 5 or 3, get one free Trezor

but the main issue with some/most of them is the fact that they don't seem to offer similar promos when Trezor is offering some and to rub salt into the wound, the usually charge higher prices than the manufacturer [it differs from country to country, but IIRC someone mentioned paying double the price in comparison to prices shown on Trezor's shop].
This is understandable. They purchase their devices directly from manufacturers at wholesale prices and have to offer it to customers at a higher price to remain profitable. The manufacturer can afford to offer discounts and special promotions but that's not the case for a physical shop limited to a smaller circle of customers. At a discount they make nothing or very little. Trezor sells their products globally and anyone can purchase them online. Their userbase is much bigger. No one is going to buy from a physical electronics shop in city X except the people close to them.

No matter if we like it or not, Ledger is a profit-driven company. Its main goal is to help themselves and have as many people as possible buy their hardware wallets and services. That's why Ledger Recovery Key works exclusively with Flex and Stax. Do you like it? Buy a Ledger hardware wallet that supports it. And guess what? Thanks to their marketing efforts, people will.

The biggest advantages of Seedkeeper, in my opinion, is the price, support for desktop machines, and no hardware/software limitations as seen on Ledger Recovery Key.

Re: I bought a Trezor Safe 3 and I have a few questions

What do you think of Trezor's approach of providing two passphrase input options: Host or device?
Trezor Model One is the only one that requires that you enter passphrases through Trezor Suite. All other models allow you to choose, but the default behavior should be to enter passphrases on the devices themselves. It's an extra layer of security. Like you said, the passphrase alone isn't enough to compromise the funds in a wallet, but why allow even it to land in the wrong hands if there is a safer way to do it.

If customers still want a faster way to work their passphrases, then let them enter it on Trezor Suite and that's what the company does. The choice is theirs. I would always prefer the safer method.

1. "Non-custodial" - This term is used as a contrast to the process of regular CEX exchanges where users deposit their funds into a custodial wallet owned by the exchange, perform the swap in the exchange, and have the output currency in a wallet owned by the exchange, before they're able to withdraw into their own wallet (if they even do that).

2. "If you refuse my exchange, the website crashes, or something else happens, how do I get my coins out without your help?" - You're correct in that you'll have to trust us for a few minutes when we process and perform the exchange. We acknowledge this and we are ready to earn users' trust with time.
What you explained is the workings of a custodial service. The deposit addresses your users deposit to are under your control. You own the keys to them. It's exactly the same as with other instant exchanges. For instance, eXch, which was very popular on Bitcointalk. After reading your T&Cs and the mention of sending customers private keys, I thought that was the case with all swaps, but as you explained below, it isn't. Exchange owners seem reluctant to call their service custodial. You shouldn't be if your intentions are good. Your service isn't trustless and it's custodial but you can build a brand here if you do it right. There is a market to fill. I wouldn't give custody any importance in your OP. Most of us here know how instant exchanges work and someone could see it as annoying when claims are made that aren't correct. 

3. "Transmitting private keys to customers" - Currently this is only when we refund DAI -> X exchanges. If for some reason we are unable to perform the requested DAI -> X exchange, we would just transmit the private key of the receiving DAI address to the user (To simplify the process, so we would not have to 1. ask users for their refund address 2. send eth to the receiving address and 3. send the DAI to the refund address).
Got it, thanks. But why only for DAI and not also for ETH or all cryptos for that matter?

Hi GazetaBitcoin,

Thanks for considering my topic worthwhile as a translation project for The Alliance Of Bitcointalk Translators. It goes without saying that anyone is free to translate anything I write into any language they want to. I will add a link to finished translations at the bottom of my OP now.

@Pmalek, whether this feature is optional or not is beside the point. The reality is that its presence introduces a potential vulnerability i.e. essentially the "door" for the SEED phrase to leak from the SE and display in this case. In my opinion, this compromises the security, as the truly secure environment must ensure that SEED phrase is 100% sealed and inaccessible at all times after it was generated by wallet and saved by user.
We are saying the same thing but in different ways. Cool
I have no objections to what you are saying and my opinion is also that the feature shouldn't be there. My suggestion for creating a secondary firmware ensures that those who don't want any seed-extraction option are kept safe from any potential vulnerabilities that may be discovered in the future. No seed extraction code in my firmware means I won't suffer any consequences if something goes wrong with it. The users who are ok with the tradeoffs would then be the only ones whose security would be impacted in case of vulnerabilities with seed extraction.

Didn’t realize there were so many legal complications around gambling in the US. I knew some states had restrictions, but I didn’t expect that even deposits and payments could be blocked like that. No wonder many casinos just choose to ban US players altogether — looks like the easiest way to avoid trouble.
On top of that regulatory and compliance nightmare you also have Federal and State laws and those could be different. According to Federal laws, something could be illegal but the State in their territory makes it legal. In the end, who is right and who is wrong? Federal agencies could prosecute you while law enforcement in your State lines doesn't think you did anything illegal. 

Marihuana, for example is one such thing where there is a conflict between Federal and State laws. According to Federal laws, it's illegal, but some States have made it legal. In theory, the FBI or another Federal agency could arrest you for possession but the State you possess it in doesn't mind that you have it.

Welcome to the forum!
Like several other users, I am also hoping to see the Tor version of your exchange.

I think you should mention the fees in your OP. They are the same as eXch used to have.
I have noticed several instant exchanges calling themselves and their services as non-custodial. You have the same claim in your OP. So I have to ask: how is the swap process non-custodial? If I begin a swap and you give me a BTC address to deposit my bitcoin to, do I have the keys to this address? If you refuse my exchange, the website crashes, or something else happens, how do I get my coins out without your help? Your TOS mentions transmitting private keys to customers. Can you tell us a bit more about that?

I am reading your T&Cs.
You apply higher service fees for amounts exceeding certain amounts. For instance, >"1 BTC - 0.5%, >2 BTC - 1%". Why is that? Shouldn't users be awarded with lower fees for swapping bigger sums instead of paying more?

And yes, what Pmalek mentions and what I tried to highlight as a quite despicable part of firmware is code that's there to have the main secret leave the hardware device completely. Oh boy, this is a can of worms and we kicked it. Yes, I'm aware, my BitBox02 allows a backup on a microSD card. Is this equally wrong as Ledger's Recovery service crap? You judge!

Displaying the wallet's recovery words again on demand feels kind of wrong to me, too.
As long as it's an optional feature that is not forced on you, then each user can decide whether or not to use it. Ideally, Bitbox shouldn't have it either. A separate seed extraction firmware can easily be developed by developers if they wanted to. At least Bitbox doesn't send this data remotely over the internet to other parties for "safe-keeping" (that we know of). It's a local digital backup. If the feature gets merged into the firmware that everyone uses, then end-users don't really have a choice. The code is forced on them. The option is there and can be activated anytime by the click of a button or a switch. It's far from ideal.
