CZ My wife is the only person I know who saw this in a theater.

I like this post because there's a lot of attention on how we are moving stables and crypto into the future world of agentic buying, and it's a fun topic. But I don't necessarily agree with the idea that x402 and MPP are racing to become THE “internet’s payments layer.” I think some of the recent discussion about “layers” is slightly off, at least in a traditional payments sense. These aren’t layers. Or rails. They don’t sit in the stack as independent infrastructure. You don’t build on top of them the way you would a network or ledger. They’re application-level functions. (Ask yourself: would you have to rewrite your application to swap between them? If you do, they aren't layers.) Both are trying to answer the big question: how does agent-driven software identify itself and manage payments without a human in the loop? x402 does it one way. MPP does it another. But in both cases, the “how” lives inside the application. Why does this matter, besides me getting to be pedantic? Because calling this a “layer” implies the competition between them is about rails or underlying infrastructure, and I don’t think it is. That will matter in terms of who controls what and how they make money. (For instance, I don’t pay to use TCP/IP.) So this is a way to define an interaction model, and I think the hope by Coinbase and Tempo is that we eventually do see it as “infrastructure” and stop questioning how it’s delivered. We will just assume this is how agents buy things. All of that is to say that I don’t think the “layer” discussion is anywhere close to settled yet. There are still real competitors further down the stack who understand payments and will have a say in how this plays out.

🚨NEW: After a Senate Republican meeting on crypto market structure attended by White House Crypto Council Executive Director @patrickjwitt, @SenLummis told reporters negotiations around yield/rewards are making progress but remain “in a delicate state,” with the focus shifting from imminent legislative text to “who we need to be reaching out to.” “I think some major light bulbs were switched on during this meeting. So, there's a path forward that is not a path that I would have expected to encounter when I walked in the room,” said Lummis. Patrick Witt, who emerged from the meeting looking frustrated, had no comment on the meeting. @SenatorTimScott emerged, smiling as always, but declined to comment, noting he doesn’t speak to reporters in the hallways.


Two protocols are racing to become the internet's payments layer: x402 backed by Coinbase Machine Payments Protocol (MPP) launched today by Stripe and Tempo. How are they different? Short answer: x402 is more permissionless. MPP is more payments-optimized. Long answer: Assets - MPP accepts stablecoins on Tempo, plus fiat - x402 accepts all ERC20s, but no fiat. Scale - MPP's sessions primitive lets agents authenticate once, set a spending limit, and settle later, batching payments across many interactions. Better for agent scale. - x402 is still largely per-request, although it’s moving toward prepaid flows Settlement - MPP requires Tempo and Stripe. - x402 permissionless, chain agnostic What's better? imo, if MPP settled on any chain, it would be a clear winner. But it doesn't. And that's a huge drawback esp since it's unclear how decentralized and permissionless Tempo actually is.

Algorithm is better today than 3 months ago?


Mayor Zohran Mamdani recently got the political equivalent of what baseball players call a brushback pitch — a fastball deliberately thrown dangerously close to a batter’s head in order to intimidate the player, who must flinch or duck to avoid a devastating injury. The mayor is getting municipal chin music from the major bond-rating agencies: Moody’s formally changed its outlook on the city’s finances from “stable” to “negative,” and S&P Global Ratings opined that Mamdani’s budget plan will “make it difficult to sustain budgetary balance beyond fiscal years 2026 and 2027.” The negative outlook from the agencies is a warning, writes columnist Errol Louis. The next step could be a downgrade of the city’s bond rating, which would raise the cost of borrowing money for routine city operations. Mamdani maintains that the decision to revise the outlook is premature, pointing out that the city’s overall credit rating remains strong and has not been downgraded. But the message from Wall Street seemed crystal clear: Unless Mamdani adopts a more fiscally conservative approach, we will punish City Hall in the markets.
