BEWARE TRAVELING TO 🇭🇰 HONG KONG WITH BITCOIN HARDWARE WALLETS
Hong Kong has updated enforcement rules under the National Security Law as of March 23, 2026.
Refusing to provide passwords or decryption assistance to police is now a criminal offense, covering ALL personal devices including phones, laptops, and likely hardware wallets.
The rule applies to everyone in Hong Kong, including US citizens, even if only transiting through the airport.
Authorities also have expanded powers to seize and retain devices they claim are linked to national security investigations.
Travelers are advised to understand the risks before entering or transiting through the region.

Decoy wallet, avian edition.

In the dry savannah and shrublands, a tiny bird, the Anthoscopus minutus builds its nest from spider silk and plant fibres
It builds a false entry and a blind chamber to avoid predation
Watch it close the ‘door’ as it leaves, leaving the false one ajar

Consider making a Border Wallet before you see the flames licking your neighbourhood.
Works great with multisig too.

I mean...
How is someone overlooking the power of @BorderWallets?
the fact you still have to write down your seed phrase 16 years after bitcoins launch is really dumb
everyones trying to build the next big l2 for bitcoin, but we still haven't even solved the fundamental issue of self custody
without an easy and safe way for the masses to self custody bitcoin, there is no point to anything we are doing here
can we stop fucking around and enable covenants so people can build out real solutions for this
@lianabitcoin @nunchuk_io @bitcoinKeeper_ are trying to solve these issues but with some form of covenants these guys would be able to work magic

S/o to the team at @BitcoinDesign, and in particular @hey_deeksha who, under the mentorship of @GBKS and his crew of volunteers, created an awesome new vision for BorderWallets.com!
We love this new look and can't wait to secure development help to bring it to life!

I will clear my diary for an interview but you’ll need to come to me @TuckerCarlson
30 Jul 2024
NEW: Tucker Carlson says he would "lay his life down for Bitcoin" if he could move from country to country with his BTC without being tracked. However, since he "can't do that," it is "less meaningful to him." 🤔

2 years ago today I launched @BorderWallets.
So many of you have helped our project in so many ways, that I can't actually name you all.
But what I can do is say that we would not have reached the number of people that we have done without each and every one of you. Thank you🫶

🧠🔑 Border Wallets 🏃♂️💨
For the last few months, @superphatarrow and I (with a touch of magic from @BitcoinQ_A) have been hammering out a way to make memorising secure #Bitcoin seed phrases easier and more reliable.
A quick thread 🧵👇🏻

Hear me out ...
Private keys as Lego builds a la @BorderWallets.
@SeedSigner scans them from each face and reconstitutes the key.
Your wealth is built with Lego. 👀

Our team talked about doing something like this during dev, but quickly realised that it destroys the entropy in the grids. While 70 grids is > 1 it still leaves only the patterns to be brute forced.
We strongly advise users to generate their own grids not just patterns. Sorry🫠
1 Jun 2024
Thanks to @borderwallets and @SparrowWallet i created two books for crossing the border securely with your seed phrases - a book full of entropy grids. Available at: amzn.to/4c2abwl

Full-marks for the presentation though - the covers and concept of making it look like a puzzle game are 👌
