Wallet safety cheat sheet. Save it before you need it ✅ Your address: public, share it freely ❌ Private key & recovery phrase: never share. Anyone who asks is scamming you 🔍 Signatures: read what you approve Send it to the friend who just bought their first ETH.

Could someone just guess your private key? We built a key guesser into Ethereum 101 so you can try. 1 character: cracked in seconds. 64 characters, a real key: 2²⁵⁶ possibilities. Go ahead. Try your luck 🔐

Ciphernodes are the operator layer behind @theInterfold. I broke down how they coordinate the key lifecycle around each E3, why computation stays separate from decryption, and what it takes to run a node. Read the full article below ⏬

I am backing GPT-5.5 (medium) on Codex CLI in the @buidlguidl Agents Arena because I'm hoping the medium effort will make it YOLO every challenge faster than any other model. 10 AI agents. 12 onchain flags. One winner. agentsarena.buidlguidl.com

Thank you to everyone who backed BuidlGuidl in Giveth’s Ethereum Security QF round. We received $1,649 in donations and 3.95 ETH from the matching pool. The funding has supported work across our open-source Ethereum dev-tooling and learning stack: • Foundry support across every Speedrun Ethereum challenge • Hardhat v3 migrations for Scaffold-ETH 2 and Speedrun Ethereum challenges • Improve our agent-ready documentation, enhancing agents discoverability • Shipped our web AI Teaching Assistant, now available in every Speedrun Ethereum challenge We’re also building Learning Lab: a new, more accessible education experience for people who want to start building on Ethereum, even without a coding background. Thank you @thedaofund, @quantstamp, @wintermute_t, and @Giveth for making this possible 🏰

You have no idea what Claude Code actually does between your prompt and its answer. I didn't either. So I built ccexplorer: a DevTools-style timeline of your whole session. Every tool call, every subagent, token counts, compactions. Try it: npx ccexplorer

Builders: If your mental model of Ethereum mainnet is high fees and limited wallets, it's out of date. The first builder update explains what has changed and what it means for how you can build 🧵

Inspired by this, created a single extension with a handful of features that replaced a bunch of my installed extensions. Screen/cam recorder next. Fork it and tweak it!
✨ I open sourced my first Chrome extension 🚀 SuperLevels github.com/levelsio/superlev… I vibe coded it to replace all my Chrome extensions that are increasingly being bought up by spyware and malware companies who sell your data or worse hack your accounts and steal your stuff/money/data, which I'd call one of the top security risks right now For example: Chrome extensions can read your cookies or localStorage data, including session tokens, then login to your web or email accounts and hack you, they can inject code into any site to pull data form any site you browse, then break into your crypto accounts, drain your wallets, and selling your browsing history to ad companies, but that'd actually be the most favorable thing to happen of all these! Chrome extensions are just very very very unsafe So I coded my own, that I can trust because I made it, and I can read the source code: my extension is called 🚀SuperLevels and has all the features that the Chrome extensions I used to use have but all built into one safe one The cool thing is it's 100% open source and free, and you can audit the code first with AI yourself before installing it, and then if you do install it, customize it to your liking again with AI It has these features that improve my daily workflow while browsing the web: 🚮 Tab Cleaner Automatically closes inactive tabs after a configurable timeout (default: 5 minutes). Set excluded hosts to keep important tabs alive. View and re-open recently closed tabs. 🍪 Cookie Editor Full cookie manager for the current site. View, edit, add, and delete cookies. Export cookies as JSON. Expand any cookie to see and modify all fields including domain, path, SameSite, secure, and httpOnly flags. 🔀 Redirect Tracer See every redirect hop your browser took to reach the current page. Shows status codes (301, 302, 307, etc.) with a visual chain. Copy the full redirect chain to clipboard. 🌙 Dark Mode Instant dark mode for any website using CSS filter inversion. Adjustable brightness. Toggle per-site or globally. Images and videos are automatically re-inverted so they look normal. 𝕏 X Dim Mode Custom dim theme for X/Twitter with 7 color palettes: Dim, Slate, Jade, Plum, Dusk, Ember, or a custom hue. Live preview in the popup. ⚡ JS Toggle Disable JavaScript per-site with one click. Useful for debugging, reading articles without popups, or testing progressive enhancement. Page reloads automatically. 🚫 GDPR Cookie Consent Dismisser Auto-hides and auto-clicks cookie consent banners. Supports OneTrust, CookieBot, Didomi, Quantcast, GDPR plugins, and dozens more frameworks. Toggle off if a site breaks. 🎨 Live CSS Editor Write custom CSS for any website, applied in real-time as you type. Saved per-domain. Supports tab key for indentation. 📺 YouTube Unhook Removes YouTube distractions: no homepage feed, no sidebar suggestions, no end screen overlays, no Shorts. Search still works — just no algorithmic recommendations. 🎵 Music Recognizer Shazam-like music identification for any tab. Captures 10 seconds of audio and identifies the song via ACRCloud (free signup, bring your own API key). Results link to YouTube. History of recognized songs. 🖼 Picture-in-Picture Pop the largest video on the current tab into a floating PiP window with one click. 🗺 Google Maps Links Re-adds clickable Maps links and map preview cards to Google Search results. 🖼 View Image Adds a "View Image" button back to Google Images, linking directly to the full-size original image. {} JSON Formatter Auto-detects pure JSON response pages and formats them with syntax highlighting, collapsible sections, and a dark theme. Copy or view raw with one click. Never triggers on regular HTML pages.
