❗ An issue was found with the v0.1.0 of the 4337 Canonical module for Safe. We ask teams using v0.1.0 module to disable it until v0.2.0 audit is completed. The audit of v0.2.0 is planned to be completed in the coming week. The new version will come with additional features.

Test in Prod is not passing the quorum for rPGF😢
As a core dev building OP Stack days & nights, it's a bit discouraging. Come on.

OP Michael@opmichael_eth
Test in Prod (@testinprod_io) literally built & now maintain OP-Erigon, are an OP Stack core developer, but are only on 8 ballots right now. IMO they are one of the clearest cases for RetroPGF. vote.optimism.io/retropgf/3/app…

@fasc1nate Technically it is more likely to Korean version of DIA not CIA because it is military based intelligence group. CIA equivalent of Korean was KCIA(now NIS), which is civil spy agency.
English
South Korea's version of the CIA recruited a suicide squad to kill North Korea's dictator, Kim Il Sung.
Eventually, the squad mutinied, murdered most of their commanders, and hijacked a bus to Seoul, which was eventually exploded with hand grenades, killing most of them.
The remaining survivors were secretly tried and executed.

@gakonst there are several kinds of optimizers
1) for hardware(e.g. fasttransformer)
2) by algorithm(e.g. quantization)
3) by hardware(e.g. TPU)
English
what categories of LLM hackers exist?
have seen fine tuners, jamstackooors, optimizers for hardware, codex libs, prod code academics
what else?

@ekzhang1 It may differ by culture. As an Asian, this might be rude at some point. Cuz we tend to deliver the message without revealing our identity directly. But, I haven't experienced it yet, another culture that might prefer direct conversation would like this way.

remind me in 20 years that I never want to send an email worded like this in my life. >:(
why do some of the most accomplished and incredible people in our industry, still act in bizarre, unpersonable ways. everything is about power, it seems.

@deadrosesxyz @bytes032 if you read audit report, you only see the red dots from the plane. if you read exploits, you are now can see the real problem.
English
@bytes032 read exploits/hacks instead of audit reports? why so?

I have been working in smart contract security for the past 10 months:
If starting over again, I'd do these from day 1:
- start contests immediately
- read exploits/hacks instead of audit reports
- avoid studying stuff I don't need at the moment
- write a POC for all my findings
- build a knowledge base with findings I found
- no CTF's (or just 1)
- spend less time caring about salty folks

I am now officially dropped out from @SeoulNatlUni today. should have done it earlier, feels like the only reason i was delaying this decision is that i was too lazy to get a signature from my prof

Breaking @erc4337 infra for fun
tl;dr
- erc4337 hash function is not generating consistent userOpHash
- manipulating userOp calldata can make inconsistent userOpHash
- I developed a wallet that generates same userOpHash for any userOpHash 🤯 and quite secure(but don't use it)

Disclosing the vulnerability that could have drained funds.
tl;dr
• latest commit of EIP4337Manager can be destructed but does not risk user’s fund
• 0.4.0 @safe based 4337 wallets are in risk of losing fund
• affected wallets are safely migrated
