Why are businesses moving payments onto stablecoin rails?
Brian Butler of Polygon Labs says cross-border firms want to move capital instantly and must match rivals' rates. Ran Goldi of Fireblocks describes a newer cohort, banks among them, starting proofs of concept after the GENIUS Act. Luis Medeiros of Protofire calls adoption still thin.
The default use case coming in is like, hey, I want to send capital globally instantaneously, right? And that leads to a better prefunding model, which leads to more efficiencies. ... If your competitor has better rates than you, you have to fix your problem, right?
Brian Butler, Payments Lead, US, Polygon Labs · Episode 4, 17:19If you look at the last 12 months, it's a totally different cohort. It's everything after GENIUS Act. It's people who now say, okay, we've heard a lot about this. It seems that there's some value. Let's say you're a bank. We're not 100% sure, but now we can touch it. Let's do a POC.
Ran Goldi, Chief Payments & Network Officer, Fireblocks · Episode 6, 21:44It's still a thin layer of TradFi, right? It's not huge adoption ... TradFi players see that we already have a legal framework that allows them to go there and to experiment, at least. We see things happening mainly on stablecoin rails for cross-border, and also tokenization of funds and assets distribution onchain, mainly.
Luis Medeiros, Field CTO and CEO of Arenas.fi, Protofire · Episode 4, 05:51Are stablecoin payments cheaper, or just faster?
Brian Butler of Polygon Labs says stablecoins mainly fix latency for now, which improves prefunding economics. Ran Goldi of Fireblocks also puts the savings in prefunding capital rather than in the transfer itself. Kostas Asimakopoulos of DDSC says users mostly notice faster, cheaper transactions.
Cross-border payments is really broken, right? ... Right now stablecoins are really solving a latency issue. I wouldn't say we're getting to the pricing part just quite yet. ... If you can solve for latency, that leads to better prefunding, which leads to better economics for these cross-border money movers.
Brian Butler, Payments Lead, US, Polygon Labs · Episode 4, 07:05The one thing that we see a lot of people skeptical about is, I guess, saving on capital requirements of prefunding, especially around not just the banks but also remittance companies. And once they start doing it, again, they don't look back, because they realize there's a lot of savings there. ... Again, not because the transfer itself is cheaper.
Ran Goldi, Chief Payments & Network Officer, Fireblocks · Episode 6, 58:06We are actually making money movement more efficient, and we do it in a way that they won't, most of the time, realize that something has changed in the back. They will only realize that transaction times are faster, cheaper and the likes.
Kostas Asimakopoulos, Head of Partnerships, DDSC · Episode 6, 03:44Will stablecoins replace card payments?
Kostas Asimakopoulos of DDSC describes paying at a UAE card terminal without a card, then agreed cards stay for the foreseeable future. Pooja Shah of Rain expects cards to stay relevant for three to five years, while some agent companies look at stablecoin rails.
You can go around and pay on a card terminal, not with a card directly. ... The card terminal there is just the acceptance device. So we also have to start thinking that cards that we are all used to not necessarily need to be in the mix anymore.
Kostas Asimakopoulos, Head of Partnerships, DDSC · Episode 6, 24:29Getting all of those merchants globally to accept either a local, sort of government-backed payment rail that's real time, or some just native stablecoin payment mechanism ... it may happen. It just may take a really long time. So I think in the timeframe we're talking about, three to five years, cards are still going to be relevant.
Pooja Shah, Head of Product, Rain · Episode 6, 30:11I didn't say that cards will go anywhere, right? I mean, for the foreseeable future at least, for sure. ... What Visa and Mastercard have built is something that you cannot switch overnight, and actually you don't want to.
Kostas Asimakopoulos, Head of Partnerships, DDSC · Episode 6, 33:33We talk to a lot of agentic companies who, they come to us because they want to issue agents cards to spend online, just with e-commerce. But increasingly we are starting to see a lot of these companies just thinking about ... machine-to-machine payments and how those will just occur directly over stablecoin rails.
Pooja Shah, Head of Product, Rain · Episode 6, 30:11What stops corporate treasurers from holding stablecoins?
Emma Landriault, speaking in a personal capacity, said client treasurers would want to check each stablecoin's reserves. Eric Queathem of Velocity thinks appetite outside Web3 is low but changing, starting with payments. Brian Butler of Polygon Labs says most recipients still want local currency.
Corporate treasurers were looking at how they would hold different stablecoins and essentially saying, well, if we are going to look at holding these at scale, right, on our balance sheet, then we need to be able to risk manage them. Meaning every single stablecoin ... what are the reserves made up of.
Emma Landriault, Global Head of Kinexys Labs, J.P. Morgan Payments · Episode 5, 28:46I think the reality is there's not a lot of appetite today for corporate treasurers to be holding balances onchain, unless you're a Web3 native business. I think that's changing, though. ... I think payments is always gonna be the starting point into holding value onchain and broader treasury management.
Eric Queathem, Founder & CEO, Velocity · Episode 6, 36:25We're still not at this stage where people are receiving the stablecoins and then just holding it. ... We're taking these stablecoins and still off-ramping them into local fiat ... because again, these different businesses or merchants still want to get paid in their local fiat in order to perform all the transactions they still need to make.

Where do stablecoin payments still get stuck: off-ramps, KYC or privacy?
Kostas Asimakopoulos of DDSC says off-ramps fall back on traditional rails, which limits instant payouts at weekends. Pooja Shah of Rain points to missing data on who transacted before the off-ramp and to KYC across providers. Eric Queathem of Velocity flags publicly visible corporate balances.
I think the bottleneck here we see is only the case of off-ramping, because then we will rely on traditional rails. And this will limit us from offering the instantaneous payout that we might like if, for example, somebody requests that during a weekend.
Kostas Asimakopoulos, Head of Partnerships, DDSC · Episode 6, 45:31The big concern that folks have had in providing off-ramp services for third parties in the space is just the risk, and how do you get the data you need, especially given that one leg of the transaction is onchain and you don't really know who are the parties that have transacted up until the point of the off-ramp.
Pooja Shah, Head of Product, Rain · Episode 6, 55:20KYC is something that comes up a lot, especially when partners of ours are working with many different providers. And they think it should be trivial to basically integrate multiple providers into one solution, and that the KYC just magically sort of resolves itself. But that's just not how it works, as I think many of us realize.
Pooja Shah, Head of Product, Rain · Episode 6, 59:25For corporate use cases, we still haven't yet solved for what does a publicly traded company, who now has balances and money movement being visible publicly onchain somewhere, do? And so I think that's probably one of the next big themes that we've got to solve and figure out how we support.
Eric Queathem, Founder & CEO, Velocity · Episode 6, 48:59Which stablecoins can a business accept under UAE rules or MiCA?
Kostas Asimakopoulos of DDSC says UAE retail payments allow only dirham-backed stablecoins. Alex Radu of Pulsar Money says a MiCA compliant app can still accept other stablecoins and bridge them to USDC. Pooja Shah of Rain says some regulators expect treasury layers to be licensed.
Many are unaware that for retail payments in the UAE only dirham-backed stablecoins are allowed as per the central bank, no other foreign stablecoin or any other crypto token.
Kostas Asimakopoulos, Head of Partnerships, DDSC · Episode 6, 24:29We need to have every single aspect of the app to be MiCA compliant, including the stablecoins. ... But that doesn't mean that you cannot basically have an integration where you accept multiple other stablecoins and abstractize everything, and basically bridge everything to USDC, for example, in the interface.
Alex Radu, CEO & Founder, Pulsar Money · Episode 6, 27:16In certain markets that we are launching in, the regulators that we work with there expect those layers to also be licensed. ... As stablecoins go mainstream, just integrating with the existing guardrails that exist in traditional finance will start to increasingly become very important.
Pooja Shah, Head of Product, Rain · Episode 6, 53:01Do banks need their own stablecoin or a deposit token?
Ilia Shirobokov of ADI Foundation calls tokenized deposits a bit more natural for banks, though stablecoins came first. Emma Landriault, speaking in a personal capacity, described a deposit token that leaves the deposit unchanged. Eric Queathem of Velocity doubts most banks need their own stablecoin.
What's interesting is today they try to just repeat the first mover steps. ... That's why we see originally, firstly, stablecoins and not tokenized deposits, despite the tokenized deposits [being] a bit more natural thing for banks, for example. But still I would use stablecoins firstly as well, because stablecoins, okay, I've seen the story, it works, nice, it's safe.
Ilia Shirobokov, Head of Blockchain, ADI Foundation · Episode 4, 08:45What's interesting with this is, a client can mint a deposit token, make a transaction, and then very, very quickly off-ramp into their account, and there's no change in the actual liability or the asset that they were holding at all.
Emma Landriault, Global Head of Kinexys Labs, J.P. Morgan Payments · Episode 5, 31:03I think there's too many banks who think that they can have their own stablecoin and it's gonna actually create a lot of value. ... The primary use case for stablecoins today is payments. In order for payments to be effective onchain, you need liquidity at both sides.
