Upgrade your frostsnap app. And upgrade the firmware on your devices when you can.
Frostsnap v0.4.0 is out ❄ It fixes two security issues. We know of no user funds lost to either, and each has a published report. Update your app and device firmware. Also: firmware downgrade protection and dozens more fixes. frostsnap.com/security/updat…

I found a SIM implant in my friend's @Ledger Flex. He set it up but never used it, so no funds were lost. He bought it from @cryptobilis at their May 22 2026 Global Pizza Party, Raintree Club Kuala Lumpur. nRF9151 LTE module, eSIM module, v1.1 UFL antenna cc @MagicalTux
Can anyone who bought Ledgers from @cryptobilis confirm (either by replying here or DMing) that their wallets got drained, disassembled their devices and found a SIM implant in it? It seems like the only victims affected are those who bought from shady Lazada merchants, not CB

😂🤣 SHORT ETHEREUM (TICKER: $ETH) INTO THE FLOOR. IT'S OVER.
Replying to @rrwilliams
In this conversation, ETH refers to the Exponential Time Hypothesis, not Ethereum (ethereum:native ). No meaningful practical impact on Ethereum’s cryptography.

Bad: All these mutation tests were not getting cleared each time and ended up using more than 1tb of space in /target/debug for one project.
Good: claude loves mutation testing now which is great. Bad: A mutation test removed a guard which narrows processes to kill and killed very process on my machine.

Announcing LayerTree: a new tree-based scaling solution for Bitcoin that permits O(1), independent of the number of users in the system: xitter.gq/lightning/status/21108… A single UTXO can hold the balance of millions of users as an off-chain Merkle-sum tree. Transaction introspection techniques permit batched exit from the system in a single transaction w/o any pre-signing: layertree.tech
Introducing LayerTree, a non-custodial scaling solution on bitcoin that connects to Lightning. Using covenants, one UXTO can be shared by a million users. Any user can leave at any time in a single transaction. Users don't need to be online to receive. Funds never time out. LayerTree is the next step in bringing bitcoin to billions. Learn more: layertree.tech

It's remarkable that the Ledger supply chain infiltration was able to grow to the scale it did given that we were aware of these implants ~6 months ago (thanks @joegrand!)

WARNING: do not leave your tamper evident bags unattended near @sakak_musdom. While waiting for an uber at the frostsnap factory I gave him a mk3 in its original bag as a parting gift. Before the uber had arrived he had completely disrespected its bag. Don't be like him. Make sure to leave evidence when you tamper with hardware wallet packaging. It's part of the ToC.

If you watch until the end you'll see the blue strip is back. If you look closely you'll see that the new blue strip is missing a watermark. Keep in mind this was cooked up in literally <5 mins while waiting for uber. If you put in any kind of effort you have no chance at noticing the difference.

The simplest way to solve the ledger implant problem: When displaying 24 word backup do not show all 24 on the device. Show 12 on the device screen and send 12 encrypted to the companion app which shows them on the screen. Record them on the same card. Easy :^)

IIRC google’s result implies can break your keys in mempool with non-noisy superconducting circuits in ~5mins so hashing doesn’t protect you. Now the next pleb slop should be that you should have a 10-of-10 multisig even with a single seed to give you 50mins of protection.

I wasn’t going to comment since this is a really bad take IMO, but since it’s taken off I feel the need to. To my understanding, there is no evidence whatsoever pointing to a break of decades old hardness assumptions like elliptic curve cryptography. 1/n
Today I call upon the blockchain industry to calmly begin planning for "bunker mode". My personal recommendation is to set in motion a controlled mass migration of assets to fresh addresses, i.e. addresses whose pubkeys remain hidden behind a hash. Holders, starting with large and sophisticated ones, should consider moving the bulk of their funds to addresses that have never signed a transaction. And when they do sign one, they should also move remaining funds to a new address (possibly generated from the same seed phrase). Don't rush. While I believe there is cause for action a rushed migration would do more harm than good. Don't panic either. Moving assets to protected addresses is a simple, preventative step which does not require new cryptography or new wallets. IMO it is now reasonable to brace for the possibility that ECDSA breaks before qday, in the worst case in months not years. By "break" I mean fast private key recovery (e.g. in one week) on available hardware (e.g. a large GPU cluster). Recent days have been humbling for human mathematical intuition. Long-held, unquestioned hypotheses have fallen. This includes the n log(n) bound for integer multiplication and the 3SUM conjecture. In hindsight, May's unexpected disproof of the Erdős unit distance conjecture was our warning shot. Yesterday's OpenAI drop made it clear that mathematical superintelligence is upon us. They say there are weeks where decades happen. We are about to live through weeks where centuries of mathematical progress happen. Could our magic 64-byte ECDSA signatures be too good to be true? Was it just security through obscurity all this time? Elliptic curves feel especially vulnerable to superintelligence. Curves carry rich structure, with room for fancy tricks like Schoof, Frobenius, pairings. (By contrast, hashes are designed to minimise algebraic structure.) Separately, as Ewin Tang can attest, an efficient quantum algorithm sometimes foreshadows an efficient classical one. We should be open to the possibility of a classical counterpart to Shor that breaks elliptic curves and RSA at once. Also noteworthy is the striking under-representation of cryptographic breakthroughs among the 722 mathematical results OpenAI published. I've witnessed first-hand the US government censoring academic quantum cryptanalysis results. Backroom interventionism is my base case. I urge large, sophisticated actors to lead by example. Project11's "risq list" (bitcoin-risq-list.projecteleven[.]com) is a great tracker of exposed BTC pubkeys. Binance, Bitbank, Robinhood, Bitfinex, and Tether have an opportunity to harden their cold storage. Next month I'll address institutions in London in a live Q&A (forum.ethereuminstitutional[.]org/london-2026). Again, please do not rush. Wallets holding under 50 BTC enjoy partial cover from "Satoshi's shield", i.e. his 20K exposed addresses that hold 50 BTC each. Load-bearing signers like oracles and L2 security councils should consider rotating ECDSA pubkeys with every signed message and/or multi-signing with a hash-based schemes like SPHINCS. Exiting bunker mode safely will require post-AI cryptography. My inclination is to go all-in on hash-based cryptography and avoid structured mathematical assumptions entirely, whether from curves, lattices, or isogenies. A single battle-tested hash (e.g. from the SHA or BLAKE families) yields plausible post-AI security. The Ethereum roadmap on strawmap[.]org fully embraces hash-based cryptography with end-to-end formal verification as a response to the quantum threat. Those timelines must now be revisited and accelerated in light of mathematical superintelligence. I'll be pushing for maximum defensive acceleration.

It's hilarious that even the curl-to-sh command for codex updates suffers from accumulated AI slop. I can't even copy it because it line wraps. Run a curl-to-sh inside an explicit sh which pipes to sh?? Some magic environment variable is required??

At this point I'm more worried about nontrivial projects that *aren't* releasing a stream of security updates than those that are. Where are my BIOS updates? microcode updates?

Threshold signatures compatible with BIP SHRINCS. Massive step forward, even if it requires a trusted dealer.
1/ You've probably heard of SHRIMPS. But have you heard of PRAWNS? 🦐 After a months-long research effort, @danboneh, @benediktbuenz, Justin, Yavor, and @nazirkamilla are excited to announce a novel thresholdization scheme for one-time hash-based signatures!
