complex software is bad.
complex smart contract is terrible.

[Anthropic @AnthropicAI]

New on our Frontier Red Team blog: We tested whether AIs can exploit blockchain smart contracts.

In simulated testing, AI agents found $4.6M in exploits.

The research (with @MATSprogram and the Anthropic Fellows program) also developed a new benchmark: https://t.co/QpGPMqlDRG

If you’re sending a transaction that sends $500M:

Don’t use the Safe UI.

Use localsafe.eth.

Once all signatures are collected on the Safe UI, anyone can submit. And, you expose what you’re planning to do to the world.

Using localsafe has no backend.

You can still mess up using localsafe, but it’s harder.

Sorry this happened MegaETH and MegaETH team.

[sudo rm -rf --no-preserve-root / @pcaversaccio]

alright, after a week of work you can now fully simulate Safe transactions _locally_ before signing and verify the transaction hashes in parallel using my `safe-tx-hashes-util` with a single command (use the `--simulate flag` simply). This lets you check exactly how the transaction will execute before you sign. Everything is local. Everything what is executed is printed in the terminal. Transparency at all cost. You trust your RPC provider here so use a trusted endpoint or the preferred solution of running your own node. I know many still do not believe me but local-first, cli-based verification is the way to go. Not hosted UIs. My verification script is _one_ fucking Bash file. Everyone can audit it by looking at exactly one file. No dependency bloat.

🚨 EIP-7702 auto‑drain case
Leaked key → delegated to a malicious 7702 contract. After bridging, the contract fallback auto-forwarded native token in the same tx—no attacker tx needed. Looks like a bridge issue, but the wallet was already compromised.

Takeaways:
- Phishers love 7702: batch signatures = one‑click drain (we’ve seen multi‑million losses).
- With a leaked key, attackers use 7702 auto‑drainers to siphon any incoming native token instantly.

Advice:
- Key leaked? Removing the 7702 delegation is useless—they’ll re‑delegate. Treat the wallet as burned; migrate now.
- Don’t sign 7702 batches you don’t fully understand.

Stay sharp and sign carefully.

🚨 Another NPM supply chain attack

`@ctrl/tinycolor` (2.2M weekly downloads) shipped malicious versions that run an infostealer during npm postinstall to scan for and exfiltrate sensitive data. The payload abuses TruffleHog, a legitimate secret scanner.

Check if you pulled affected versions, pause installs/updates, and pin to known-good releases.

I recently realized that the best way to go faster is to really understand how big companies' code works deeply and see if there are gaps I can improve upon.

[Patrick Collins @PatrickAlphaC]

I made a 🦊 wallet plugin that:

1. Decodes your calldata
2. Uses that decoded data as input to an AI
3. Which then searches the web to see if the transaction has anything "fishy" about it.

Here is an example where you'd be sending money to the ByBit hackers, but it catches it!

From the world's highest IQ record holder : Jesus is returning soon. The end is near. To summarize my calculation regarding the return of Jesus Christ, here are the key points. Isaac Newton, the father of modern physics, believed that Bible prophecy is not symbolic mythology but a divinely encoded timeline governed by precise mathematics. He applied a prophetic equation: Y equals Y0 plus P, where Y0 is 800 AD (the year Pope Leo III crowned Charlemagne, marking the rise of the Holy Roman Empire as the prophesied political-religious power), and P is 1260 years, derived from the biblical “day-year principle” where one prophetic day equals one historical year (as supported in Ezekiel chapter 4 verse 6 and Numbers chapter 14 verse 34). The result: Y equals 800 plus 1260, which equals the year 2060. This number appears consistently in Scripture: the figure "1260" shows up in Daniel 7:25 and Revelation 11:3, 12:6, and 13:5, revealing a recurring divine pattern. Furthermore, Einstein’s theory of relativity proves that time is not fixed. In relativistic terms, time experienced by one observer is different from another, meaning that the phrase “this generation” in Matthew 24:34 must be understood as flexible, potentially spanning 70 to 100 years, not strictly 40. From a quantum physics perspective, prophecy acts like a wave of probability that collapses into reality only when consciously observed. This is expressed in the exponential formula: P equals 1 minus e raised to the power of negative lambda times t, where lambda represents the global prophetic awareness rate and t is time since Israel's rebirth in 1948. Using lambda equals 0.03 and t equals 77 years (as of 2025), the probability of prophetic fulfillment exceeds 90 percent.

To quantify this further, I define the Prophetic Convergence Score (PCS) as the average of five key indicators, each normalized from 0 to 1. First, earthquake frequency has increased dramatically in the modern era, with the U.S. Geological Survey noting a more than 10-fold rise in magnitude-6 or higher quakes per year compared to a century ago. Second, moral collapse is evident in the global normalization of abortion, sexual immorality, transgender ideology, and the legal persecution of Christian values trends that align with the “days of Noah” and “days of Lot” Jesus warned about. Third, technological acceleration, following Moore’s Law, has reached exponential levels: AI, genetic editing, surveillance, and global connectivity now mirror Revelation’s warnings of centralized control and human modification. Fourth, global gospel reach has crossed 90 percent according to missions agencies, with the Bible now translated into over 3,600 languages and satellite or internet evangelism penetrating even closed nations. Fifth, apostasy within the church is observable in the rise of progressive theology, LGBTQ-affirming congregations, and pastors who deny biblical authority all predicted in 2 Thessalonians 2 and 1 Timothy 4. Each of these indicators now registers above 0.9, yielding a PCS of 0.928 well beyond the convergence threshold of 0.9 that signals prophetic alignment.

Therefore, I, as the world’s highest IQ record holder, testify not by superstition but by reason, physics, history, and faith: the return of Jesus Christ is not only foretold. It is mathematically inevitable. The timeline is real. The variables are set. The King is coming soon, most likely before the year 2060.

Of course, only God the Father knows the exact day and hour of Jesus Christ’s return. Yet we can estimate the general timeframe because God has revealed prophetic signs and numerical patterns in Scripture. Though the exact date is hidden, clues through symbols and history help the discerning recognize the season. The Bible is not a mystery to remain closed, but a divine code meant to be explored. I’ve used logic, faith, and reason to study the signs God has already made clear.

@0xinfini online card is a game-changer: near-zero limits, no value lost, plus you earn ~5% interest automatically. Way ahead of other online card options.

[Patrick Collins @PatrickAlphaC]

We need to talk about hardware wallets.

1. If you have one, you're probably signing transactions without checking calldata.

2. If you don't have one, you're more susceptible to hacks.

One of these needs to change.
