You can run full Haskell Cardano node in a web browser. Also balance and submit transaction fully on a browser as well.

In contrast:
When you build a Bitcoin hardware wallet from off-the-shelf components, a supplier data leak doesn’t expose anything Bitcoin-related.
No one can tell those parts were meant for a wallet.
We have some difficult news to share. Unfortunately, one of our shipping providers has experienced a data breach that exposed sensitive order data. This affects new customers in the US, UK, Sweden, Colombia, Brazil, Italy, and Portugal who received an order within the 90 days prior to August 8th, 2026.
The data exposed:
- Full names
- Shipping addresses
- Phone numbers
- Email addresses
The incident affects 11,742 customers with full exposure (name, email, phone number, shipping address) and 1,947 customers with partial exposure (name, city, email). The breach is limited due to Trezor’s strict 90-day data storage policy (we were also able to negotiate the same terms with fulfillment partners, who follow the same policy).
All affected customers have been contacted separately by email.
Our systems and devices remain secure, but affected customers could experience an increase in phishing attempts.
NEVER enter your wallet backup on a website or share it with anyone, and only check for updates on official Trezor channels.
We are deeply sorry to the community and those affected.
We are investigating this situation and will post updates on our blog:

Introducing Mesh Skills: open-source AI skills for building with @meshsdk's developer platform.
Developers and AI agents can use them with Cursor, Claude Code, Codex, and any agentic tooling that supports skills to generate better integrations for transaction building, wallet operations, and smart contract interactions.
As the agentic economy grows, the context provided to AI systems becomes just as important as the code itself.
Use it now: npx skills add MeshJS/skills
Introducing Circle Skills: open-source AI skills for building with @USDC, EURC, @Arc, and Circle’s developer platform.
Developers and AI agents can use them with Cursor, Claude Code, Codex, and any agentic tooling that supports skills to generate better integrations for stablecoin payments, crosschain transfers, wallet operations, and smart contract logic.
As the agentic economy grows, the context provided to AI systems becomes just as important as the code itself.

Introducing Cometa.py a full Python binding for libcardano-c!
github.com/Biglup/cometa.py
If you work with Cardano in Python, this is for you. 🧵👇
Aiken is bundled inside, that means you can:
• Compute execution units locally
• Apply protocol parameters to scripts
• Perform script evaluation entirely offline
Repo: github.com/Biglup/cometa.py
Examples: github.com/Biglup/cometa.py/…
Docs: cometapy.readthedocs.io/en/l…

What is fascinating about yesterday's event is how Cardano recovered from a minority chain and got rid of the symptom while preserving most of the history and progress since the incident.

I am gonna go out on a limb and actually say this is pretty cool. Nakamoto style consensus without proof of work is extremely hard to build. The protocol functioned as designed in the presence of bugs.
Angel Castillo retweeted
some smart people tell me there is an earnest smart developer community in cardano, and now that the awful opportunistic money people have been washed out, the chain has a bright future
hard for me to tell from outside, but I hope the community gets its fair chance to thrive🦾🦾

My UPLC fest presentation:
- "Pushing the Limits of UPLC: Everything is Possible" -
is available. I cover some incredibly powerful smart contract design patterns and techniques. Please check it out if you are a dApp developer on Cardano.
Check the thread below.

Top-level domains .ada & .cardano?
Seems like a must-have to me, but it more seems polite and mature to align with the ecosystem on this. A lot going on in background already.
DReps, your call 🫶
Cardano support incoming :) projectcatalyst.io/funds/14/… 🚀

You plan to vote on @Catalyst_onX this weekend? Here is our recommendation with @_KtorZ_, Waalge and Julien for the Open Dev category: forum.cardano.org/t/catalyst…
In particular, I’d like here to highlight a few of these that are among our favorite picks this round.

In vegas's governance workshop we identified as community that one of the largest hurdles toward effective governance is lies on drep <> delegator communication.
We build to solve that problem🤙

First time doing interviews — yeah, I was nervous 😂
Still, nothing beats the excitement of helping the community grow with more devs.
More videos are coming, stay tuned 👀
