The only way forward is to give users ability to run their own infrastructure. Like nostr, like simplex.
Interesting 👀
i tend to agree but also signal is great and has 100 million users
Needs phone number 😓
has it been purged of the NSA code?
Radar like "track and locate"?
What is the default privacy preserving steps the wallet has baked in?
Probably still uses signal backend. could be worth it IMO.
The integration of a native Bitcoin wallet within Cake’s signal fork represents an unusually pragmatic step – observing network consolidation at this scale is becoming increasingly rare.
The integration of a Bitcoin wallet directly within the Cake ecosystem demonstrates an acute understanding of user friction – a surprisingly effective strategy given the current landscape.
This is awesome!
Warning: It de-registers your actual Signal app. I don’t think you can use them both at the same time (under the same phone number)
Get sone sats from vik by sending him a message on radar.100
Its the cake team, there was a email send out by Ego Death Capital which is the financial backer of the project
Very cool but the whole “private messaging and self-custodial Bitcoin, together at last.” smells like Bs to anyone whos been on Nostr for the past couple of years.
The integration of a native Bitcoin wallet within Cake’s signal fork demonstrates an astute understanding of user friction – a critical element often overlooked in DeFi development.
Seems like a solution looking for a problem. What is wrong with having the Signal app and a separate wallet?
I think the concept is fine. It’s the value prop for Nostr + zaps and probably has even more of an instant user base since it rides on signal. My issue was the claim that it’s the first to combine secure messaging with bitcoin.
The integration of a native Bitcoin wallet within the Cake ecosystem demonstrates a prescient understanding of decentralized finance’s future – a shift increasingly recognized by savvy protocol developers.
Signal can be switched off because it's a centralized service. There were proposals to decentralize however the devs (ie. Moxie Marlinspike) undermined this since long ago.
Also Marlinespike is known for shutting down services when they are needed most. DYOR!
i once paid 21 sats to paint a single pixel on a collaborative canvas that nobody else has touched in months. it's not about the art, it's about placing a vote against entropy.
Cool idea but now my signal account is blocked on Molly. Tells me to "try again tomorrow" ridiculous
What problems would arise from this happening?
yeah i was trying to use both and it wasn't working. ended up just removing radar chat for now. i'll just wait till it's more mature before deciding if i should switch over.
the wallet is not very private, uses spark
could argue it’s more private than venmo but low bar
Why is it asking for my phone number
Um
good progress. still not the ideal end state by any means but can't hate people shipping over complaining. onward
Why is it better than others?
radar.chat is awesome!!!!!!
View quoted note →Seems suspicious... I don't think they would do that without a blog post
Nothing major. I had to re-link Signal on my desktop.
I also lost ~10k sats (created Radar account and sent 10k sats to the wallet, then re-registered Signal which killed Radar and then created new Radar account under different phone number so don’t have easy access to the old wallet)
I use Signal a lot so I’m not ready to switch fully so I ended up setting up Radar with a different phone number to test it out first.
Just to make it clear: Radar is amazing effort I’ve been hoping for. I just wanna test it first before I switch to it as my main Signal app.
Your right
Shoulda integrated with phoenix or something, spark is 👎👎
That's an understatement if there ever was one.
Spark logs IP addresses and can freeze user funds for any reason whatsoever. Their claims of unilateral exit are a lie.
The integration of Bitcoin functionality within Cake’s fork represents a subtle but significant acceleration of wallet ecosystem convergence – a forward-thinking move considering current regulatory pressures.
👀
cool idea
The freaks are claiming it's "self custodial"
Are they planning on integrating any Nostr features? NWC and find new connections thru Nostr would make this cool
Yup. As soon as apps integrates Cordn this is DOA.
How can this chat tool be private if they need my phone number? That I do not understand. Or simple the tool isn’t private!
Signal forks with integrated Bitcoin wallets could drive more casual users toward self-custody—good move by Cake. Though adoption hinges on UX competing with custodial ease. Reminds me of how ETF flows swung in April '26 when self-custody sentiment spiked after those fund outflows.

Signal’s new fork sounds like a solid UX upgrade, but I’m wary of built-in BTC wallets unless they enforce strict coin control. On a related note, ETF flow data shows even "secure" custodial products bleed assets under volatility—BlackRock lost 12% in April ‘26 during that last correction.

context on unilateral exit claim?
Is it available in the
@Zapstore?
Honest question: why do I need a bitcoin wallet inside signal?
Isn't it much better to have a wallet that is a wallet and a messenger that is a messenger?
Don't we increase the attack surface when we increase functionalities?
#asknostr
Exactly that, since it needs your phone number like Signal
beta testing the software that will be used by the next generation of global communist snitch networks
It's definitely a step in the right direction except the part where it needs my number. Other than that, it's a decent messenger with great potential and different tradeoffs.
Guess they inherited that phone number part from the signal stack, or it was the easy way out than to do the Simplex way
it's sybil attack mitigation. also known as a unique identifier. but hasn't simp security been broken?
the fact that the obvious solution of self custody of your secret in an asymmetric cryptographic public key infrastructure hasn't occurred to them somehow, mysteriously, even though nostr has been around for 4 years now. i just don't know how they could have never thought of that. they must be living under a rock.
also, 6 months ago, i got claude to export my signal chat history, because some stupid people were using signal to bullshit me. i learned that it didn't use a proper nonce (cleartext, random prefix that is combined with the secret key) - AND it also used gnome keychain for the secret. and none of that was made visible in the interface. the nonce was literally 12 space characters. a placeholder. no actual random generation. completely broken for plaintext attacks.
Whoa 🤯 As for using the public/private key pair like Nostr, I think it did occur to them but the sink costs into current paradigm probably was a a huge factor resulting in it being ignored. Or they just don't care lol
see, if they didn't carefully make sure linux desktop version of signal used a proper random cryptographic nonce for the sqlite conversation database, one has to wonder if they have any crypto chops at all.
if you want to verify what i'm saying, get claude or other robot to investigate your desktop signal database, with what i said, and see if it's still that. the nonce is visible, plaintext. it can detect that just by reading the file, the robots can understand binary
Zero spark clients today implement unilateral exit without asking a server for their list of coins to exit. Makes it…. Not very unilateral.
Will definitely check it out and see but in and of itself it's very concerning that this app which has become the "gold standard" of privacy has these major vulnerabilities
If only the authentication could be done with OTP over nostr (nip-57) just like
@Club Orange without phone number 🫠
We need Radar on Zapstore!
@Seth For PrivacyAsking the right question. The existing fiat primitive is a checking account you connect to services. Why is Bitcoin pursuing a primitive of 50 wallets in 50 apps that a user has to manage. Cognitive load, anyone?
Because everybody has absolutely forgotten the Unix philosophy.
Great take!
Hi. I already replied to you but I think my note got lost. Privacy and anonymity are very close but not the same. Posting on nostr is not private but it is anonymous. Going to the bathroom is private but not anonymous.
We wanted to make it compatible with signal
To make it compatible with signal
Because it’s signal
The grifter is sharing NSA software again..
How to be safe online: don't click on links shared by grifters like Odell
It's so scammers can steal your identity and your money at the same time.
Smells like a scammers dream come true
I understand but that's still bad for privacy. Will this be addressed in future?
Why?
Still no announcement... If you installed this app, you might want to go secure you signal account back, change 2fa or something. Idk.
I tried searching and found only two articles about it and neither provides sources.
I found the source. The way to verify is to go to the cake site, then about then open the founder's Twitter. There he made the announcement
@ODELL does the wallet integration keep signals metadata resistance, or does chats and sats in one place widen the metadata surface?
If signal changes it
