24x dev strategy
when running 24x claude code instances makes sense: 1. an initial agent scanned my repo looking for general improvements. it flagged 20 things. I liked 12 of them and told it to create a github issue for each 2. I opened up 12 tmux panes and ran `/fix <issue_number>` in each

Apparently, we've reached a point of no return where AI audit quality is indistinguishable from a human-made one. If you are using Solarity library, please update to v3.3.0 asap.

Monetary incentives for open source contributions have a big challenge, as they greatly incentivize LLM spam and make it even harder for maintainers to evaluate design and code quality. Even worse, they're one PR away from accepting a malicious patch disguised as a feature.

🚨 twitter is rolling out geodoxxing it shows country you registered in, county of app store you use, country you are connected from. right now visible to you when you click on joined date, soon to everyone. go to settings - privacy - about your account - use region/continent

this is disastrous that you needed to be terminally online and had less than 24h heads up to switch away from twitter showing your country to everyone. awful rollout with no user choice or consent whatsoever. this was the exact case for a terms of service update email that would

After years running SEAL 911 and coordinating incident response, we've identified a critical gap: while many protocols have strong smart contract audits, there's no standardized way for them to demonstrate operational security maturity. Today we're issuing an RFC for our newest

Be careful as lots of keeper/bot services are integrated into APIs that rely on Cloudflare for rate limits.

this is obviously a bait since it's 10x easier to find crashes in C code than to find logic bugs I don't even have to define invariants here

today I spent ~$100 on claude building a fuzzing campaign for https://t.co/vUSF6hptlj + fixing bugs it encountered extremely cheap if you ask me imagine if you could have the same for web3

🔥 New SEAL Frameworks just dropped! We’ve seen too many attacks via preventable infrastructure issues, weak multisig setups, and wallet security gaps. So we built new frameworks that any protocol can implement: → Domain & DNS security: https://t.co/DfrKequNo1 → Multisig

We’re excited to announce that Size Credit is now Rheo! DeFi has dissolved geographical borders, but not yet overcome its own divisions. Capital remains frenetic - pooled to largely stagnate, or evaporate without warning. We built Size on the thesis that as sophisticated

ONCHAIN CTF: Exploit the contract, keep the ETH I've loaded up this vulnerable contract (linked in reply) with 0.1 ETH. If you can find the solution to take the ETH from the contract, it's yours to keep No, there's no source code. Good luck Note: Be careful to ensure you don't
