π¨ JUST IN: @Marqeta partners with @zerohashx for stablecoin-linked cards
Marqeta is bringing stablecoins into everyday card spending, with zerohash providing the stablecoin infrastructure. Stablecoin-linked cards will be usable at tens of millions of merchants worldwide.
Any Marqeta customer can now embed stablecoin payments into new and existing card programs without rebuilding core systems or taking on new regulatory burden.
I like this because, Marqeta has a lot of existing scaled customers who might want this feature. Think about Square, Western Union, DoorDash, Uber, Affirm Klarna and Ramp. Some of them already have stablecoin products.
The timing makes complete sense.
Visa ran 130+ stablecoin-linked card programs across 50+ countries last year and expects that number to roughly double in 2026. Volume grew 319% to ~$5.2bn.
Tiny next to Visa's $14 trillion, but growing faster than anything else on the network. Consistently.
And the demand is genuinely there. Companies like Kast let people in Argentina, Nigeria or the Philippines receive dollars and spend them directly. Netflix, Claude, flights. No currency switch, no local bank account required.
What I wonder about is whether Marqeta can compete on the economics.
The breakout player in this category is Rain. $1.95bn valuation, reportedly ~38x volume growth in 2025, and a structural edge: it's a Visa principal member operating from Puerto Rico, so it issues directly and keeps interchange the traditional stack splits three ways (sponsor bank, program manager, processor).
Marqeta in the US requires a bank underneath. That bank takes a cut.
So the fight in stablecoin cards comes down to this.
Marqeta has distribution: thousands of live card programs that can switch this on tomorrow.
Rain has economics: more interchange per swipe to fund rewards and win issuers.
Classic innovators dilemma.

Major narrative violation: The big banks ARE doing stablecoins.
@Zelle says it is expanding to India and will launch a stablecoin later this year.
For context: Zelle is the largest P2P money transfer service in the United States, larger than Venmo or Cash App, and built by the large banks.
The parent company Early Warning is owned by seven banks: BofA, Capital One, JPMorgan Chase, PNC Bank, Truist, U.S. Bank, and Wells Fargo.
They're launching the app in India but NOT the stablecoin.
This makes sense as India represents the largest outflow of remittances from the US, flowing there.
India is, however, not particularly fond of crypto, so I'm not surprised to see Zelle being more cautious about naming the stablecoin for that corridor.
The @kontigo_app vs Checkbook & JP Morgan drama is pure πΏ.
I wanted to give it some context. Because the claim of "banking system is evil and outdated" is simply wrong and lacks context.
Here's what I think is really going on
JP Morgan closed accounts for crypto startups Kontigo and Blindpay
The information reported that the account freezes were linked to business activity in high-risk regions, including Venezuela, and to gaps in customer identity checks.
From Tradeweb: βJPMorgan acted after seeing rising disputed transactions and chargebacks tied to these accounts. The bank said the decision was based on risk controls, not opposition to stablecoins themselves.β
To understand this, there are a few things we need to unpack:
π§ There are three players here. Checkbook, JP Morgan, and the start-ups themselves.
- JPM banks Checkbook.
- Checkbook "banks" Kontigo.
- Kontigo serves the End User.
EMVCo (the technical body behind Visa, Mastercard, Amex) is creating global standards for "agentic payments."
This is the biggest change in card payments since "tap to pay"
Here's how it works π§΅
Right now, AI agents are phenomenal at finding things to buy.
- Power users are starting to default to their research
- Can compare complex options and summarize
- And when people click through conversion is 2x to 5x higher
But...
There's no agreed way for payment to happen
- There's countless protocols
- x402 for agents accessing other tools
- ACP and A2P from Open AI and Google
- Visa and Mastercard have their own approaches
