A Disastrous Loss Of Funds And How To Avoid IT In The Future [In The Thread Below]
@bl4ckb1rd71 was using github.com/rainshowerLabs… for this a while back Lmk if u have specific feature requests and maybe I can add it?
The protocol @Balancer appears to have been exploited — about $70.6M in assets was transferred out, including: 6,587 $WETH($24.46 M) 6,851 $osETH($26.86 M) 4,260 $wstETH(~$19.27 M) etherscan.io/tx/0xd15520726…
The Solidity function dispatcher is a tree where: - Internal nodes perform binary splits. - Leaf nodes contain up to 4 function selectors, tested linearly. Protip 1: the `fallback` function's bytecode is generated twice in the bytecode. To reduce bytecode size, wrap the…

whenever i want to reverse engineer an exploit, this is what i use to guess functions sigs
🧩Sourcify is taking over openchain.xyz's signature API • Verified contracts auto-add new signatures • Playground → 4byte.sourcify.dev • Switch to api.4byte.sourcify.dev (openchain compatible) This week we're gradually shifting the traffic to our servers

Auditors & SC devs, thank me later: Clone any verified on-chain contract into a local Foundry project with `forge clone`. [PATH] is optional - it’s just where the code will be saved. Works on any EVM chain. Great for audits, bounty hunters and reverse engineering.

Here’s a powerful trick to get up to speed fast when reviewing unfamiliar smart contract code using @cursor_ai 👇
Introducing Private Multisig -- a special multisig where no one sees who votes or how votes on proposals. The ballots are encrypted, and the whole voting process is non-interactive. Achieved via ZKP + ECC ElGamal + DKG + HE. Trustless and permissionless. No TEE needed.
This is the power of YOLO, trained on a laptop for ~1 hour, with a Kaggle dataset. Oh, and just ~100 lines of Python. I can make a startup on this and it took me literally a couple of hours.
NEW: Investigations into the Hyperliquid whale who shorted the market just before Trump’s tariff announcement allegedly point to the World LibertyFi team for leaking the information.
1/ The investigation into the insider trading ring has taken a decisive step thanks to various sources whose identity I will keep anonymous. Garret doesn't seem to be the main actor. He is probably just a frontman, but this was the starting point for tracking the real insider…

1/ After posting the White House pictures, I have been contacted by various entities and after further researching, I decided to compress everything into a new post. It appears that some of the privileged info obtained by parts of the Hyperliquid whales shorting before the…

Foundry users, big update: Backtraces are here! Now failed tests (reverts, assertions, errors) show full stack traces - internal calls, fallbacks, line numbers, etc. No more blind debugging - you see exactly where and why it failed.
Foundry has a new release candidate: v1.4.0-rc3! Highlights include: backtraces, configuration inheritance & multi-chain configuration, forge fmt powered by Solar🌞, enhanced coverage guided fuzzing, custom precompiles & many performance improvements! $ foundryup -i v1.4.0-rc3
Q) When I work with Cyfrin I get paid straight away after an audit, but when working with firms X/Y/Z it takes weeks and even months to get paid. Why is that? Being asked this a lot over the last few months; without knowing the internals of firms X/Y/Z, there are a number of…
