This is equivalent to trying to sell a cop drugs while he’s in uniform in his police car.

Super cool 🇪🇺 initative!

@paulg @dadiomov Stablecoins transactions also have fees.

Card fees are just an artificial (and temporary) limitation. If Visa / Mastercard see volume slip away, they could reduce / remove them for a subset of transactions (especially micro ones).

@ankurnagpal @ankurnagpal welcome to my hometown! when are you going to be there?

I'm gonna be there too (19<>22/may), would be nice to catch up in person if you're still gonna be around!

also, DMing you a list of recs 🎯

[Matteo Gamba @sliver86]

The spend is primarily funded via credit card rails… but I expect a future where a pre-funded balance (powered by stablecoins) will be available within the Link Wallet, enabling micro-transactions and alternative payment use cases (e.g. deferred payments/BNPL)

[Matteo Gamba @sliver86]

As expected, @stripe just opened up @link (its wallet solution) to AI agents, enabling them to directly access all the information inside of the wallet (payment credentials, but not only) to autonomously complete online purchases on your behalf.

[Stripe @stripe]

Today, we’re launching the @link wallet for agents. It lets you securely empower agents to spend on your behalf. Your payment credentials are never exposed and you approve every purchase.

[Matteo Gamba @sliver86]

The owner of the wallet stays in control.

You get to approve all the transactions, and soon you will be able to granularly delegate more autonomy to agents, let them purchase without approval within specific previously approved boundaries (e.g. which merchants, what amounts).

[Matteo Gamba @sliver86]

@SaveOnSend Curios what is going to happen once that regulatory void will be closed (because it’s just a matter of time… especially with a technology that is intrinsically MORE traceable!)

[Matteo Gamba @sliver86]

@Harrisbro777 we need that energy to train AI models!

[Matteo Gamba @sliver86]

@Similarweb @Similarweb what about meta?

@RampLabs can do you successfully handle with 3DS authentication?

[Matteo Gamba @sliver86]

@SebJohnsonUK for those looking for the link: https://t.co/4pzzNeWzUk

[Matteo Gamba @sliver86]

@0xSammy This framework is a good first step, but it does NOT meaningfully solve the problem:
1) it requires ADOPTION at the entire industry level (including thousands issuing banks… good luck with that!)
2) it does not grant fraud LIABILITY SHIFT (the merchant remains responsible)

@aidaxbaradari @be_inaudible you should translate this video to German, instant product-market fit 🇩🇪 😅

@keyserfaty How is authentication (3DS) handled when requested? That’s an important piece to solve as well (actually, MORE important than accessing the card details)

[Matteo Gamba @sliver86]

The level of productivity enabled by AI is insane 🤯

[@levelsio @levelsio]

This week I decided to just permanently switch to running Claude Code on the server mostly on bypass permissions mode:

c() { IS_SANDBOX=1 claude --dangerously-skip-permissions "$@"; }

And for the first time in my life I think I've actually managed to outrun my todo list

What happened is I simply blasted through my to do list of features I had to build and bugs I had to fix

I've never shipped so fast and Claude Code almost made no mistakes, and when it did it they were tiny that weren't fatal (important because I'm mostly working on the server in production now)

Before I was always known to ship fast (also because I always work alone) but while I shipped new things would always build up on my features/bug board (my users can submit them there)

But this is the first week where I've been fast enough to outrun them

The board is actually empty!

As other people have written on here the real bottleneck is becoming myself and my creativity, not how fast I can ship. Because I think I ship faster now than I can come up with new ideas, or maybe my brain will adjust to this new speed (probably)

Also I feel another limit is becoming my own mental context window, as in how many things, features, bugs, projects, I can keep in my mind in parallel while building on all of them. It's a lot and I haven't reached that limit yet but I feel I might be close

I also noticed that you start going really fast the more you let it just go loose, before I was slow because I didn't trust it and I was scared it would destroy my code, now I just let it go. As @karpathy wrote, things feel like they've changed a lot around December last year when models became good enough to really code with and I feel the same

When I see other friends code with Claude Code I often notice they're slow because they still check everything, which is good of course, but I feel the better way would be to create some tests and just let it run freely and see if it can pass those

For me the tests are mostly just me checking out if the new feature on the site works or not, and in 99% cases it just does, and then I ask it to improve it further

Because I run Claude Code on the server in production, I don't have to wait for deployment anymore (although that took only 3 seconds anyway before, that still adds up), now it's wait for it to be done coding, I refresh the site and I test it, that feedback loop is how I work and it's made me WAY faster

Anyway here's what I did this week and the majority of these things were requested by people on the bug board, I'd say this is about 10x my normal output:

📸 Photo AI
- Built new image viewer and mobile image viewer
