Tip to auditors. A large chunk (if not all) of your job is to get your head around a codebase, and a diagram worth a million words. This is Renzo's completed queue withdrawal from the last Code4rena audit, generated automatically:

Reproducing the $41M Curve reentrancy hacks with Echidna demonstrates the simplicity and effectiveness of external on-chain fuzzing. It highlights how even basic reentrancy checks in fuzzing suites can uncover complex vulnerabilities and illustrates the critical role of

A little treat for Solidity devs. Once you understand this, you will be ahead of 99% of Solidity devs in understanding memory.

Fast Codebase Onboarding If you're new to a project, tell Cursor to create a Mermaid diagram of the codebase and chat with it. It will help you get familiar with the structure.

That is the easiest way to chat with a complete Github Repository!👀 Replace "github" with "gitingest" in the url, and you get the whole repo as a single string, paste into AI studio and use Google DeepMind Gemini 2.0 Flash Million Token Context video to ask questions! 🤯 Here

In case you want to sandwich Four.Meme trade, here is the sandwich bot code that made us $100K profit in one day 6mo ago and still works today: github.com/fuzzland/fourm…

Don't feed AI your entire codebase. LLMs don't read code - they match patterns. A CodeMap strips your code to its essential patterns and relationships. Show less code but show the right signals. Stop flooding the context window with noise.

It used to take me hours to write security reports, using AI now it takes minutes. How I use Cursor to write security review reports. The process is largely inspired by @0xEV_o post a few months ago. 🧵 Here's my workflow:

Logical reasoning and Q&A framework using OpenSPG and LLMs

The playbook is easy: 1) Make an mcp server that does something useful (e.g. making beautiful UI components) 2) Let people sign up for an api key, first 5 requests are free 3) Increase limits for $20/mo 21st dev did this really well

On Feb 17 2025 I reported a critical vulnerability to Scroll. $100m+ in TVL was at risk for more than 2 months. Anyone could force Scroll L2 into an indefinite re-org, halting the chain so that no user transactions would be included in blocks and the chain would not move

Holy shit... Tencent researchers just killed fine-tuning AND reinforcement learning in one shot 😳 They call it Training-Free GRPO (Group Relative Policy Optimization). Instead of updating weights, the model literally learns from 'its own experiences' like an evolving memory

Agentic traces contain perfect information about an agent’s behavior with every plan, action, and retry. But that information gets lost in a sea of JSON. So we built AgentPrism: open source React components that turn traces into visual diagrams for debugging AI agents. You can

I never run out of content to post anymore. Built an automation that monitors 50+ news sources, scores articles for relevance, and writes social posts automatically. It finds trending topics in my niche before they explode everywhere else. Saves me 15-20 hours monthly and

The dirty little secret of Prediction Markets... is that Arb bots make millions off of retail due to neg-risk market inefficiencies. I created a bot to capture the arb for the retail traders themselves. In the screenshot below, using this bot you would save $800 on a $10k
