Back in August I posted that we’d seen the feedback about changes to Phantom, especially the ones that made it harder to find the core actions users rely on day to day. We heard you loud and clear and are now rolling out a number of fixes. Here's an update on where that stands.
Send and Deposit buttons are rolling out front and center on the Home tab again, you can create seed phrases during onboarding, Apple Pay on-ramping now lands in seconds, not longer. These are the first of a much bigger set of changes rolling out now in response to your feedback.
We’ll keep shipping until we’ve made Phantom as easy to use as it used to be, so please keep the feedback coming.

Replying to @phantom
@phantom coming in at #30 on LinkedIn’s Top Startups 2026 👻💜 kinda iconic. love this for us!!
LinkedIn Top Startups 2026: The 50 U.S. companies on the rise linkedin.com/pulse/linkedin-…
Everyone thinks companies dump bad news on Friday in hopes it’ll get overlooked heading into the weekend.
Reality: they planned to put it out on Thurs, spent all week debating it and on Fri finally decided “F- it, just put it out as-is so we can deal with next week’s crisis.”
Exactly what I would expect (from a quiz I answered honestly)
You asked, we delivered. The @JoinFAI Field Guide to the Tribes of Silicon Valley is live now.
27 tribes, a few easter eggs, and a 3-minute quiz (just for fun).

The first mission of the Church is to help people be attentive to the profound questions of life: those concerning our origin and our destiny, as well as those concerning the meaning of love and suffering. The logic of profit at all costs and the manipulation of information risk exerting undue pressure on people to conform to a lifestyle centred on the consumption of material goods, but our hearts are made to look upwards. #GeneralAudience
If you are 40 years old and watched tv at 11:30pm when you were 13, you just know he's about to cut the string attached to his hip.
Look at this guy learning new things. The reason I like this video so much is because we’ve all seen Ben succeed and we’ve seen him fail. But anyone has the chance, right now, to do what he’s exhibiting in this video. Which is simply take the time to learn this new thing.
Ben Affleck (Hollywood star & Artists Equity CEO) talks about how he fine-tunes open video models by unfreezing weights and trained only the last cinematic layer so a film crew can hit real production standards.
for context, Ben Affleck founded InterPositive in 2022, a 16-person AI shop for film post and Netflix bought it in March 2026 for $587 mn in cash.
He needed that model because public video models were trained on his peers' films, and he did not think that was a real business. So InterPositive raised money, shot its own dataset for 8 months on a controlled stage, and used it only as late-stage training.
Each new film then trains a private model on its own dailies, so the production keeps the footage and the learning. That is the product Netflix paid $587 million for.

One time my 4y/o asked if she could look at my phone while I had X open. She posted something like "kbdn3j". It immediately got 1 like from @giancarloMKTS.
"Dada do you like what I typed?" I said, "Oh, yeah, and apparently so does...uhh...Chris Giancarlo, former CFTC commissioner. He's known as CryptoDad, kind of like Hester Peirce but..."
"can you just get my banana now?"
The author's copy just arrived! 📚 The New Adventures of CryptoDad, assisted by my son @lukegiancarlo. #CryptoDad comes out Oct 27. I think readers will really enjoy it. Pre-order:

Phantom's no-action relief from the CFTC is now available to all non-custodial software providers.
Few things make me prouder than being part of a team that sticks their neck out to change what's possible.
Even prouder when it starts to benefit the whole industry.
In March, Phantom became the first passive software provider to receive no-action relief from the CFTC. We're grateful to the CFTC for working with us to chart a new path for non-custodial software providers to connect people with regulated markets, all while the provider never holds users' funds or makes decisions about their trades.
Now the CFTC has opened that same path to other software providers, and that's a win for the whole industry. This is how it should work: software built to protect consumers, paired with regulated partners, giving more people safe access to the financial services they want 🤝.
I am so @Muse-pilled that I'm pouring personal information into Facebook like it's 2006 and I just woke after a questionably-themed party with a full SD card.

Arc is live in @phantom today.
Circle built it on a simple idea: money should be internet-native. Real-time, always on, settled fast, interoperable. We agree. Congrats to @arc @circle and @jerallaire.
Big picture: markets should be open to anyone, usable by anyone. Everyone should be able to control their own money, and plug into markets that never close. That's the freedom of open markets, and every rail like Arc gets more people there.
