Join us today on the Nogal stage at La Rural 5:45 PM!
Transaction Simulation Spoofing (TSP) is a new class of TOCTOU-based attacks that can drain wallets, users, and dApps alike. @theFrBrGuy, Founder of @IPSProtocol, will show at DSS how these attacks work and how to defend against them.

💣 We caught @ycombinator–backed @gecko_sec stealing two of our CVEs, one on @ollama , one on @Gradio. They copied our PoCs, claimed CVE IDs, and even back-dated their blog posts. Here’s the full story 👇

Thrilled to announce I’ve joined @Corkprotocol as CTO. After a great run working for top web3 projects, traveling to conferences, and winning hackathons, it’s clear where I want to focus: bringing TradFi onchain. 🧵 Let me share what convinced me to join Cork (+ we are hiring)

From a simulation that looks safe to a full wallet drain, that’s the risk we need to talk about. I’ll show how TSP + EIP-7702 can be a deadly mix, and how we can protect users while improving UX. Grateful to be speaking at @summit_defi and to share results from my @ethereumfndn

The winners will be those building infrastructures that embrace high standards, and compliance as essentials for integration, not as obstacles. Ethereum is taking the lead, industrializing its technology to become the backbone of the internet’s next layer.
Today we're entering Phase 2 of the Trillion Dollar Security initiative. Covering wallet security standard, solving blind signing, reducing likelihood of deploying vulnerable code, research for in-protocol security improvements, and more. See the full post in the link below:

Encoding and comparing would allow us to validate whether the original intent matches the actual outcome during block building. If they don’t align, the tx owner could choose to proceed, or cancel the transaction entirely. Does this model hold up? let's discuss.

Tx Simulation Outcome ~ Intents A user's intent can be defined by the simulated outcome of a transaction. If the simulation aligns with their expectations, it becomes the basis for their intent. Is that all? Nope, MEV is still a problem. But we might have a solution ↓

Web3 intents are making a comeback. To enable AI-driven or automated trading, intent-driven abstractions feel more relevant than ever. Revisiting this brilliant piece by @0xquintus & @gakonst surfaced two key insights... https://t.co/iCXUwGAst6

Crypto companies or employees will never ask to copy and paste: 1. Your private keys 2. Your seed phrase 3. Your account passwordsAlso: NEVER connect a USB key or cable you didn’t order from a trusted source. Same for cables are they could carry malware that infect your devices!
