The @battlechain testnet is now LIVE.
Come enter the ultimate red-team platform.
Give us feedback so we can launch mainnet very soon, and fix web3 security.
Patrick Collins retweeted
we will finally kill "stack too deep"
the next @ethereum update brings both:
1) the ability to deploy larger contracts
2) lets compilers fix "stack too deep"
eth dev is going to rip in Q4
Unrelated, for any crypto x CrossFit peeps:
I just registered for Battle at the Monument 2K26 on Oct 31, 2026

Hey all,
Some of you may have noticed, but I’m taking a little break from making content.
I’ll be back soon.
Thank you

Security at Lotus
Lotus is built on the belief that onchain lending should be underwritable. That standard applies to the protocol itself.
Our holistic security posture is built across three pillars: economic design, smart contracts, operational security

Every protocol we've audited faces the same gap. Code goes from audit to mainnet with real money and nothing in between. No staging. No adversarial testing. Just hope.
We built something to fix that. Introducing BattleChain. Trial by Fire. 🧵

whoops-a-daisy
🚨Taiko drained for ~$1.7M. Root cause: a private key committed to a public GitHub repo.
enclave-key.pem, the RSA key used to sign all of Taiko's SGX enclaves, sat in the public taikoxyz/raiko repo. That key is the whole trust model.
The attacker derived MrSigner from the public key, signed their own malicious enclave with the leaked key, and registered as a trusted prover. The L1 contracts trust any enclave whose MrSigner matches. It matched.
From there: forged SGX attestations on fake L2 blocks, processMessage() sets the message to RETRIABLE, retryMessage() does zero proof verification, funds leave.
No key theft. No social engineering. No SGX exploit. Just a .pem in a public repo.
Good opportunity to recall that SGX is broken. But here, nobody even had to break it.
It's just yet another key management failure. The whole system was only ever as strong as the secrecy of one RSA key, and that secrecy depended on a human not running git add . on the wrong folder. AI greps every commit of every public repo at machine speed. Assume that is already happening.
The only real exit: a verifier that checks a succinct validity proof of the L2 state transition. It trusts no enclave, no MrSigner, no operator discipline. It checks the math. In that world this exact attack becomes cryptographically impossible rather than operationally unlikely, because there is no privileged key whose leak forges the entire system. There is just a proof.
Stay safe.

My first Web3 security audit payout!
Could have been a lot better, but right now I'm actually one of the happiest men alive.🎉
Watched 4/5 @PatrickAlphaC 12/24 hour long videos, learned from past contest results, did a ton of reading and finally got some results.
Two wallets now support ERC-8213
The list is growing

1/ ICYMI: Clear signing is now live.
Hear how the Ethereum ecosystem is coming together to make transactions readable.
This one resource changed the trajectory for so many people. Some built their own audit firms, making millions by protecting billions, and many started making six figures a year.
Either they watched this, or recommend it anyway - youtube.com/watch?v=pUWmJ86X…
Gotta appreciate @PatrickAlphaC👏

1/ An exciting unlock for @ethereum builders participating in the Ethereum Security Subsidy Program…
As of today, we're onboarding a select group of AI scan and security tooling providers to the subsidy program, making sure projects at all stages of funding and audit readiness can harden their security with industry-leading providers.

🚨 BREAKING: Active supply chain attack across npm, PyPI, and Crates.io.
Socket detected TrapDoor, a crypto stealer campaign hitting 34 malicious packages and 384 versions and artifacts, with attackers repeatedly pushing new releases across ecosystems.
TrapDoor targets #crypto, #DeFi, AI, and security developers, stealing wallets, SSH keys, cloud credentials, GitHub tokens, browser data, env vars, and API keys.
Socket detected releases with a median detection time of 5 minutes, 27 seconds. The fastest detection occurred 58 seconds after publication.
