Where are your services available? What are your plans about expanding your business in South East Asia, especially in India?
reply
Our services are already available pretty much anywhere. We are a non-custodial solution. Which means we facilitate peer-to-peer payments and not for a single second do we hold user funds. So regulations are not a problem (at least at this stage). We'll see how things evolve. Basically you can already use Flash in India if you want! Feel free to reach out to us, we can help you get onboarded!
We will soon be addind support for more currencies (visually, we only use lightning of course) to help user onboarding. We want to make payments easy and to the same standard as companies like Stripe. The difference is that since we're non-custodial, you can get started and monetize in 2 min, literally. No need for KYC or anything like this
reply
The KYC is a big problem here. The government doesn't let us buy or sell Bitcoin without it. The government taxes 31% actually for any profits you make with Bitcoin and any sats you recieve as gifts.
I don't know how does flash work but people here are t ready to accept Bitcoin payments for goods or services because everyone thinks that it's kind of illegal to accept Bitcoin.
Does flash change Bitcoin to USD in real time?
reply
Oh yes, I actually heard already that the government is pretty agressive against bitcoin in India :/
Are these taxes on top of the typical taxes you have to pay for business sales? Unfortunately, it might not be interesting for local payments just yet, but it might be an option for selling abroad. Maybe products can be charged for at a premium, allowing the cost of taxes being less felt at the end of the day. In the end, governments change and all of this will be legal. And when it does change, it will be all of a sudden. Being early is great. That's part of the reason why we made Flash free to setup. We only charge a fee after the merchant earns.
We do not currently provide btc to usd in real time. We do want to provide such services, but only through partnerships. The moment we are the ones to do this, we will have to start KYCing our users and other issues can follow for merchants. We want to stay as far away as possible from that, and need to find the right partnerships + integrations to solve for this.
reply
Thanks. I don't know how the taxation would be for business sales because it's not clear from whatever rules the government has mentioned and I've never come accross a merchant, not even in the biggest cities, who can tell me how these work.
The rules only mention that there's a flat 30% + 1% TDS applies to profits made through virtual digital assets. The rules also mention than VDAs aren't currency and they can't be used as legal tender, I assume this means "can't be used as MoE.
reply
Hmm yeah that's pretty bad indeed, and definitely lacks clarity. We plan on doing research around local laws around the world for accepting bitcoin payments and managing accounting + taxes. Look out for that, as we want to release it in Q1 :) I hope we'll be able to answer these questions for a lot of people!
reply
Thanks. I'll curiously wait for the release.
Until then I'm also looking for the clarity on these. If I'll meet one merchant, I'll update you.
reply
No questions. Just thanks for building and for showing up here!
reply
Thanks for reading! Happy to answer whatever question I can :D
reply
Finally someone with some sense.
reply
I had no idea about Flash, but I've seen your documentaries and they're fantastic! Great work advocating for Bitcoin. Thanks for all you do! Any plans for a new doc?
reply
Thanks for that! Happy you enjoyed my previous work! I think storytelling is an amazing tool for passing messages across and orange-pilling at scale. The next step is payment solutions that are as simple as in the fiat world to bring people into the world of self-custodial, peer-to-peer, KYC-free payments. That's the purpose of Flash. A great personal story and a big reason for starting Flash was the custody of my ad revenue held by YouTube for months, while all I wanted was to be paid!
Regarding a next film, I answered this to another question here :) Yes: The Fight for the US Dollar: https://youtu.be/SHXnHmKEQsE?si=lchwq2U7f54AP2bR Have been super busy with Flash, but I'm lucky to have people part of the production that are super passionate and want it to be finished. We have all the interviews, a first very basic version and the script. So we're going to move on this again. We want it to be released in 2025!

Hi Pierre, with all of your programming knowledge, which one language do you recommend for someone interested in showing an interest in Bitcoin lightning?
reply
Hey! Go for Javascript! Particularly take a look at these libraries:
  • alby-js-sdk: https://github.com/getAlby/js-sdk
    • Use it for all payment experiences. Particularly the Nostr Wallet Connect part. You can easily build apps and connect wallets like Coinos, Alby, soon the Flash wallet too and directly allow for push and pull payments
  • nostr-tools: https://github.com/nbd-wtf/nostr-tools
    • Use this for the nostr stuff, particularly think about it as user management. So for example Flash users, Primal users, FeDi users, etc, can all log into your app directly.
Also, make sure to code with a tool like ChatGPT - will make the learning process more pleasant and definitely will speed up your work!
Good luck and reach out if you need any help!

Brilliant thanks Pierre 🫂

Nice flashing tool, look's really promising.
  • What have been the biggest challenges building it?
  • How many people in the team?
  • When more integrations are planned to be released?
  • Why 1.5% fees, when the avrg on the space is 1%?
  • What's "Physical PoS"? Are you planning to provide hardware too?
reply
Thanks! We're excited to have you test it, and happy to help!
  • I think the tech is tough. And removing friction in the user onboarding. There's a lot that can go wrong and adoption doesn't work if users don't understand how to use it.
  • There's 7 people working with us right now! Not all full time, though!
  • We are releasing Woocommerce and Shopify next week! We're super excited about this. Next will be Wix, likely in February!
  • 1% fees are done by Opennode and Speed. I think it's alright, but they are custodials. We believe a non-KYC environment and self-custody is better. And it comes with a price. If you price yourself higher, you are more exclusive. And with our new integrations, we will be the bitcoin payment gateway with the most tools out there, in full self-custody. That said, we are still exploring our pricing strategy and plan to offer different plans to different users, based on usage, etc. Our fee system is already built with flexibility.
  • Physical PoS is the one you would use in-store, in person. As opposed to a "digital PoS" that could be used for an app like uber eats for example. (This is also coming soon btw)
Hope this answers it all! :D

That's a great start, really. Well done!
1. The webapp is really user-friendly and had no problem registering and start playing around. 'll see no issue to onboard users, if not the fact that some may lack understanding of bitcoin itself. So maybe on-page education could be a bonus for newcomers. However, the onboarding tool is really useful and well-structured. 3. Really looking forward for these two first integrations. 4. This apprach make a lt of sense now. The detail on not being KYC is a big deal, I was loking around to see if there was any detail n that. Did not find any on the landing page... It could be maybe more esplicit? Or you prefer keep it as a hidden gem? WHat if "authorities" at some stage force you to implement it?
reply
Thanks for the feedback on the web app! We're about to upgrade it even more to walk the user through the full setup and land on exactly the right page to get started for what he's looking for. Our focus is really on the user experience and guides in the platform, so I'm happy you picked this up.
That is a good point. No KYC is indeed a big deal, but we want to be careful on not confusing new users either. We are still trying to find the right way to show these groundbreaking features for payment processors, without overwhelming the users. I mean they'd get slammed with "No KYC, non-custodial, peer-to-peer, instant global payments, etc". For a non-bitcoiner, each of these is a rabbit hole in itself hehe
But education is a next step we want to be able to unlock in-app in as many places as possible, including in our documentation and as part of our soon-to-come onboarding checklist. This even gave me an idea: we could have an "Education checklist" in addition to the onboarding checklist. Very easy, very useful.

What's the biggest obstacle to Lightning really taking off in your opinion?
reply
User experience is a tough nut to crack. Because you need to balance ease of use and setup with self-custody. Custodial solutions are easier of course, but I don't think it's really worth it. For self-custodial use-cases then it gets tricky. Channel managemnet, liquidity management, etc. I do think we're at a turning point, though. Where smarter developers than me have solved a lot of these tricky points and make it easier for developers like me to build and focus on user experience. We're still figuring out a bunch of these issues ourselves at Flash, but the next releases we make will be great in terms of user experience and app connectivity. It's just a few weeks away now!

What the doneness of steaks do you prefer?
reply
Haha! I love my steaks, you have no idea! I eat some multiple times a week. And it depends who makes them! At a so-so restaurant I'll often ask for rare, because they'll likely overcook them. At better ones medium-rare is fine. I rarely trust them to make them as good as I do. I try to keep them medium rare when I cook. I have a whole process (like most people I suppose) and know how to get them just right for my taste!
reply
Yes, I'm on the same position. No matter how they call it, I'd like to get medium in results

Hello Pierre Corbin, a real pleasure my name is Miranda, I am CEO and founder of Xnova Solutions, online project of IT solutions, one of my current visionary desires is to include the payment by LN , of BTC in my network, I would like to know more about your network, wallet and especially how to apply it to my platform.
my web link: https://xnovasolutions.mitiendanube.com/ this is the Xnova project.
one of the problems I have faced is the KYC, in NiceHash when I set out to do BTC mining and receive payments in another wallet outside the NiceHash platform. I would like to know more about your wallet project, no escrow, just GPL license, how would it be? i would like to know more about LN at this moment is the payment network that i use with SN, using a custodial wallet. waiting for your precious answer. thanks for being in SN. sats for all.
reply
Hey Miranda, it's nice to meet you!
KYC indeed sucks. Both for you and for your users depending on what your platform also does. Happy to help you understand this better for your business and see if maybe we already some tools that can help at Flash. If not, happy to try to find a solution together :) Please write an email to me directly and we can take it from there: pierre.corbin@paywithflash.com

What is your favourite movie? Do you prefer to watch at home or in the theatre?
reply
I love going to the movies. I feel like a little kid then, every time! And I had a period of going at least once a week. Recently, though, this has changed. First of all I feel like there aren't a lot of movies that are worth going to the movies.. So I'm more of a home watcher.
Favorite movie... It's hard to say, but I really grew up with a passion for UK gangster films: lock stock and two smoking barrels, layer cake, snatch, etc. Many of my friends hate me because I love rewatching films, and I always like most films. "Yeah, but the lightning was perfect" kind of movie geek. There was no way I wouldn't get into film with this attitude.
reply
What, if any, regulations in the bitcoin industry would you like to see changed?
reply
The travel rule towards self-custody sucks. And the fact it's coming into the EU and UK is horrible. But we'll manage to get around this. I think it'll force builders to get more into the 2 core principles: self-custody and peer-to-peer. At Flash, we're about to change the game for business payments. We already never tough user funds, but as soon as our self-custodial wallet is live, we'll really be able to provide enterprise quality payment experiences, that are fully peer-to-peer and self-custodial. This is what drives me forward. Because building anything that doesn't follow these 2 standards is just not worth it. We're reaching the stage in bitcoin development tech that it is becoming easier to build such things. And it's the way forward for the internet. But all the businesses or exchanges relying on custody, they better buckle up, because I think it's going to be a touch blow for them in the short term.

I'm always excited to see more innovation in the self custodian space. It's amazing to me how few people control their own bitcoin.
reply
100%
But from building I understood it. It's so much easier to go the easy way and choose custody. After all, that's why banks and companies like Stripe do it. Even if it's a temporary custody. But this will change soon. The tech is mature. And I hope we are the ones at Flash that will lead the way, and make it easy enough, well documented, interoperable and fun so that all others join the movement. We want to show them how

What was the most surprising thing you learned building flash?
reply
Pivot pivot pivot. You hear this a lot, be open to change and questioning yourself. But when it's the week of the first release to the world, and then on the day before, you decide with your co-founder to change gears completely because it's too niche, and the work you did in the last 6 months is not good enough... It's tough. But that's how startups work, so you go with it and it somehow works out.
The next thing is resilience. Bootstrapping is tough, we went the route of raising money. And if you doubt for a second, if you lose vision, if you stop pushing, sending reminders, to the point where you feel like you're annoying everyone, I think you won't make. Persistence is key.
reply
What excites you most about your roadmap in 2025?
reply
Well, Q1 is going to be about stabilising our current tools and the release of our self-custodial wallet. I can't wait for this already, as it will be a completely new type of wallet, and the best integrated for earning through Flash and for subscriptions.
We have new groundbreaking things planned following Q2 for which we already have build Proof of Concepts. Too early to talk about in details but it's about unlocking true pay per click experiences, via automated micro transactions in full self-custody.
reply
Awesome, will have to check those out! Thanks for showing up here and for your contributions to the space! It’s gonna be an amazing year!

Thanks for the question and reading. Very happy to be here! I agree, 2025 will be an amazing year!

reply
What's been the most difficult part of building Flash?
reply
Well, now that we raised money, the difficult part is patience. Of course now we're no longer building Proof of Concepts that just work. Now it has to be production ready. And the whole building cycle has changed, and has slowed down. It makes it much more difficult, especially when there are partnerships and people waiting for us to finish. Always feels like we're lagging behind the demand and it really gives FOMO as it feels like opportunities are slipping away. But they rarely are. Other businesses are also slow ;) No stress, always take a breather, as long as we move forward every day, we're winning.
reply
Are you Polish or just living in Poland? Very curious what the Bitcoin situation is looking like over there! Is there a decent meetup scene?
reply
I just live in Poland. I'm French and Spanish. Lived in Poland most of my life, though. There is a nice meetup, but the organiser is always travelling so they happen too sporadically. The bitcoin scene otherwise is pretty small. A lot of crypto stuff instead. But we try to change this. I co-founded the Bitcoin FilmFest, and it happens every year in Warsaw. Next edition will be May 23-25. You should come! Last year's was amazing, and the biggest halving celebration in the world!
reply
What's your favourite Bitcoin podcast and why?
reply
I have to admit I listen very little to bitcoin podcasts nowadays... I used to listen to What bitcoin did a lot. It really got me into bitcoin, and was a great inspiration for my documentary. So there were plenty of ideas from there. But now, I spend all day on bitcoin topics already for work, I tend to listen to audiobooks or business/product focused podcasts

Welcome. Thanks for this.
What is the biggest hurdle you face in terms of merchant adoption?
reply
The technical aspects of bitcoin, and the lack of easy tools. I think this will all change tbh, but the truth is that we are constantly redirecting users outside of our app for a wallet, an then connecting it to Flash. It's great, but a new concept in Bitcoin with little compatible wallets. I think this will change soon, though. We will soon release our wallet, it will have amazing features and will be super simple, working both on mobile and on desktop, automatically, no hassle, full self-custody. It's gonna be a special one

I do. And she's the best. Super supportive, always. I always say it: without her, Flash wouldn't exist. It's great to build a business, but you need a partner that can accept the dedication you have to something other than her, but that will also help with ideas and push you to do things you're naturally not comfortable doing.

What's something you believe about bitcoin that few bitcoiners agree with you on?
reply
That the crypto crowd is better at building than bitcoiners.
And that's just to my point about user experience, dev experience, etc. Somehow they get it right. I think crypto is just better at building something, making it fun and sticking around. On the other side, bitcoin devs are great at building amazing tech, make it open source, and move on to the next thing.
But that's great, now that I got into building in bitcoin, I realised the land of opportunity that there is. Because I will build and stick to creating the use-cases, thanks to the amazing tech that was built before me
reply
The bitcoin protocol wasn't designed to replace modern banking and payment applications. For instance you can't charge a bitcoin wallet with a recurring payment as it only allows for push payments. But that's something a lot of companies today rely on hence stripe became a very valuable fiat company. What are your thoughts how bitcoin and lightning and possibly other protocols can catch-up to the features the digital economy needs today, starting with recurring payments but also other things like apple pay.
reply
Well, that's what we're trying to change. Although bitcoin was created only as a push payments network, ~1.5 years ago, Bumi from Alby developed a great new tech called Nostr Wallet Connect. This brings pull payment functionality to bitcoin. Which is truly groundbreaking, because it unlocked direct debit in self-custody. I think this is a game changer that will allow users developers amazing use-cases, while never holding user funds, thereby going around all current regulations, and using bitcoin the way it was meant to be used: peer-to-peer and in full self-custody. At Flash, we're trying to build the strong use-cases that leverage this and can mimic the payment experience of direct debit in fiat. We offer recurring payments for subscriptions for example. We automate our fee capturing thanks to this too.
