πŸ§‘β€πŸ§‘β€πŸ§’β€πŸ§’ The Gang’s All Here

In 2019, Facebook tried to launch a global stablecoin called Libra, later renamed Diem. Visa, Mastercard, Stripe, and Coinbase all signed on. Regulators opened fire, the card networks fled within months, and the project died.

Seven years later, the same four are reportedly back at the same table, this time without Facebook and with the law on their side.

Stripe, Visa, and Mastercard are close to launching a joint stablecoin platform, according to three people familiar with the plans, and Coinbase is weighing whether to join.

No details of its function were shared, and every named party declined to comment or stayed silent, which usually means a thing is real enough to protect. The market filled the silence with fear as shares of both Circle and Coinbase fell on the report.

The detail that matters most is who is in the room. 

Visa and Mastercard are a duopoly that almost never builds anything together. Rivals of that size only join forces against a threat large enough to outweigh the cost of cooperating. eMarketer called it an unusual alliance driven by the need for scale to win stablecoin spend, and the threat is easy to measure. 

Stablecoins moved $33T onchain in 2025, past the $25.5T Visa and Mastercard cleared combined. The card networks are defending $13.5T in payment value that will run on their rails this year, and stablecoins let money settle without ever touching them. So the platform is defensive at its root. The four want to own the onchain layer and keep collecting the toll after money stops riding the cards.

Apart, none of them holds the full stack. Stripe brings issuance through Bridge and the Tempo chain. Mastercard brings BVNK and its compliance layer. Visa brings settlement across nine chains and a Global Stablecoin Advisory Practice. Coinbase brings the deepest dollar liquidity and the USDC relationship. 

The one thing none of them owns alone is a neutral layer that ties it all together, and a layer owned by one of the four can never become the standard, because the other three will not route their business through a rival's rail. This is the reason Visa and Mastercard exist in the first place, as bank consortia that built shared networks none of them controlled alone.

πŸ΄β€β˜ οΈ The Internet of Value

A fair objection sits here before we go further. What follows is a rough rambling of what I believe this project could be. 

As a crypto native, the first idea made no sense to me at first. Then I pictured the alternative, and nobody is going to open a wallet to mint ten million dollars, bridge them from Base to Solana, swap them into euros, and spend them, juggling a different protocol at every step.

Blockchains already settle payments, final and instant and peer to peer, with no clearinghouse anywhere in the flow, and removing that middleman was the entire point. The catch is that a blockchain settles one token moving on one chain. It does not turn USDC on one network into a euro token on another, or into spendable pesos in a merchant's account, and that conversion runs through a scattered chain of bridges, exchanges, and market makers, each with its own liquidity, spread, and risk. 

Blockchains are the internet of value, open and nearly free, and money riding on top still needs a trust layer, the same way the internet carried information for free yet Visa still had to exist to move money across it. 

The stablecoin boom made this sharper. Every bank and fintech now mints its own token, from PayPal's PYUSD to Ripple's RLUSD to Wells Fargo's WFUSD, which means more dollars, on more chains, with less connecting them. That fragmentation is the exact coordination problem clearinghouses were built to solve, and it came roaring back.

πŸ—½ Toll Booth or Token

With that said, two platforms make sense:

One, the clearinghouse. The base case, and close to what the reporting describes. 

A neutral clearinghouse lets any stablecoin on any chain clear through one system with finality, netting, and compliance, and it holds the pooled liquidity to convert between them in a single step, so a payment sent in dollars lands in euros or a local token without the detour. eMarketer described exactly this, a clearinghouse-style platform that could direct the lion's share of volume to one place and make the myriad of stablecoins interoperable. 

Clearing and settling between institutions that do not trust each other is the single thing the card networks have done best for fifty years. The platform ports that competency onto crypto rails, and whoever owns the neutral clearing layer collects a toll on everything that moves through it.

Two, the network dollar. A neutral coin backed by all four, built to be the common unit the whole system settles against. 

The catch is that a coin breaks the neutrality that makes the card networks money, since backing one token alienates Tether, Circle, and every other issuer they need on the rail. It is the boldest call, and the one most likely to never ship in this shape. 

Coinbase is the swing vote, because joining means betting against its own USDC franchise and the Circle revenue deal that renews in August, which is exactly why the market marked both down, and probably why the report said they were "weighing whether to join”.

So what's it gonna be, a toll booth, or the token that pays the toll?
