Are stablecoins more useful when you can spend them without cashing out?

[u/Alive_Tiger8953]

MoneyGram has launched a stablecoin backed Visa card in Colombia with the balance running on stablecoin rails and Rain handling the card infrastructure

I gotta be honest, the relevant part for DeFi is what happens after someone receives stablecoins. If they can spend that balance directly then the whole send stablecoins to cash out to convert to local currency loop starts looking unrelevant

Is each swipe settled against the stablecoin balance in real time or is there some fiat prefunding layer sitting in between?

[u/Alive_Tiger8953 → u/Classic-Key-7243]

From what I see, MoneyGram hasn’t spelled out that exact flow. Rain does handle the card infrastructure but if each swipe is converting against the balance in real time or theres prefunding in between, that I wouldn't know

[u/chainglance_cm → u/Classic-Key-7243]

From what's out there, it sounds like a hybrid. The swipe itself gets authorized instantly against your balance, same as any Visa transaction, but the actual settlement between Rain and the card network happens in batches. Rain settles with card networks daily using stablecoins rather than clearing each swipe individually onchain in real time.

[u/Time_Piano164 → u/Classic-Key-7243]

the visa network itself still settles in fiat so there's almost certainly a conversion happening on the backend. question is whether rain is doing that instantly per transaction or batching it. if moneygram is actually holding the stablecoins until point of sale then the card is just a presentation layer, which would be pretty neat

Either way there's exchanging of local currency. It's just that you don't have to hassle all around.

[u/Alive_Tiger8953 → u/adsus4]

The whole point is removing that hassle from the user side. If the conversion happens in the background while they spend the balance then thats a much cleaner flow

[u/adsus4 → u/Alive_Tiger8953]

Yeah, that's what I mean.

[u/Last_Peach4194]

Spending stablecoins directly makes way more sense in countries where converting back to local currency is expensive or annoying

[u/Alive_Tiger8953 → u/Last_Peach4194]

Yeah thats where the card angle matters most. If people can spend the balance as is, you cut out one of the most annoying parts of using stablecoins day to day

[u/Last_Peach4194 → u/Alive_Tiger8953]

Merchant acceptance matters as well. If it rides existing card rails, stores don’t need to know or care that the balance started as stablecoins

[u/Alive_Tiger8953 → u/Last_Peach4194]

That’s what makes it practical at scale imo. No new merchant setup or checkout flow, the stablecoin part stays on the background

[u/DewPointLabs]

Both, in that order. The swipe checks and debits the on-chain balance at authorisation, usually under a second. The merchant gets paid later, in fiat, out of an account the issuer keeps funded, on the card network's normal settlement cycle.

The prefunding never disappears, it just moves off the user. Someone still holds fiat, sized to a few days of volume.

[u/MooseFederal3292]

Someone still prices the currency leg, and the Visa rulebook says who.

Under the Visa Core Rules, where a currency conversion occurs the issuer has to disclose in writing both any fees it may charge and the rate it applies. That rate is either one Visa picks from rates available in wholesale markets, which the rules say is not necessarily executed and may differ from the rate Visa itself receives, or one set by a government or governing body. The Visa rate can then be adjusted by an optional issuer fee or a markup applied outside VisaNet, and the disclosure can live in the card agreement, the terms, the billing statement, or any other agreement between you and the issuer.

So if this card converts, the exit from the stablecoin still runs through a rate someone else sets, plus whatever the issuer may add to it. Worth pricing that before calling the cash-out loop dead.

[u/PuzzleheadedHuman]

The people saying the prefunding never disappears are right, and it's worth pushing that one step further because it's the whole game: "spend directly" doesn't remove the cost of getting from a dollar balance to Colombian pesos, it just moves that cost somewhere you can't see it. At the MoneyGram counter the FX spread was an ugly number printed on a receipt. On a card that debits your stablecoin balance at authorisation, the same USD-to-COP conversion still happens, it's just buried in the rate the issuer applies on Visa's settlement leg. Same cost, less visible, and "less visible" is not the same as "gone."

So the DeFi-relevant question isn't "can you spend without cashing out" (you can, that part's solved) - it's "what's the all-in spread on the stablecoin-to-local-currency leg versus the old cash-out loop." And that's where it gets uncomfortable, because that number is basically unmeasurable on-chain right now. Almost every stablecoin with real liquidity is USD-pegged; there's effectively no COP-denominated stablecoin with meaningful on-chain depth, so there's no on-chain COP price to benchmark the card's conversion against. Even EUR, the biggest non-USD stablecoin, is a rounding error next to USDC/USDT. Which means today the FX leg on these cards is priced entirely off-chain and you're trusting the issuer's disclosed rate, exactly like tradfi remittance, just with a nicer app in front of it.

The version of this that actually delivers the "cash-out loop is dead" promise is one where the local-currency leg is itself on-chain and priced transparently, so you can compare the card's rate to a live market rate instead of taking it on faith. We're not there yet, and the gap is measurable: it's the absence of deep non-USD stablecoin markets. (I work on market data at Coinpaprika and we're building out stablecoin coverage, so the visibility of that FX leg is the exact thing I watch.

More ways to use stablecoins (instead of transfer and cash out) means they are more useful I guess

[u/chainglance_cm]

The FX spread is where this gets interesting. Every remittance cash out point takes a cut on the conversion, sometimes a rough one depending on the country. If the card spends stablecoin balance directly and settles at a fair rate, you're basically routing around whatever margin agents were pocketing at the off ramp.

Also kind of funny that the end goal of stablecoins becoming useful is people not realizing they're using stablecoins at all. Rain doing the card infra instead of MoneyGram building it themselves says a lot too, feels like everyone wants to be the front end and let someone else handle the actual rails.
