Just went through OpenAI’s Oct 2025 report on “malicious use of AI” Some takeways from that is bad actors aren’t inventing crazy new AI hacks. They’re mostly bolting models onto old playbooks (malware, scams, info ops) to move faster & make fewer mistakes.

Most teams still treat security like a final checkbox before mainnet. We built QuillShield so security becomes a continuous adversarial game your own AI plays against you. Here’s how teams use QuillShield as their Red Team Co-pilot of Web3 👇

Now it's time to Test & ship: ngrok http 3000 → set NEXT_PUBLIC_URL → cast your frame (Use App). Generate frame env: npx create-onchain --manifest. Prod: NETWORK=base, set CDP_API_KEY_ID/SECRET, prod wallet, plus rate limits, logs & server-side validation.c For the full deep dive, hit Coinbase’s x402 Miniapps docs: docs.cdp.coinbase.com/x402/m…

Understand the MiniApp structure & How it works. Like x402 gates server routes. In middleware.ts price /api/protected (e.g. $0.01 on base-sepolia). Client wraps fetch with wrapFetchWithPayment; server verifies, Frame SDK enables miniapp UX. Keep secrets in env + enforce the right chain.

Before you start, You’ll need : • Node 18+ & pnpm 10+ • Wallet to receive funds • (Mainnet) CDP keys Do this :- -> Clone & install the repo -> Build the monorepo once -> Copy & edit your workspace -> Set env & run → open http://localhost:3000

Ever heard of Miniapps? Miniapps are lightweight apps that run inside Farcaster clients (e.g., Warpcast, TBA). Built with MiniKit, they feel native while leveraging Farcaster’s social graph and the user’s connected wallet. Now let’s ship one with in-flow USDC via x402 in under an hour. From “hello world” to paid features before your coffee cools. Dive in 🧵

Cooking something crazy? Can you guess👀

Did you know How it works? -> It analyzes your repo to build a threat model → Scans new commits against it → Reproduces issues in a sandbox → Attaches Codex-generated patches for one-click PRs. Plugs into GitHub & your existing workflow without slowing dev.

Meet Aardvark, @OpenAI's Agentic security researcher (private beta), powered by GPT-5 It thinks like a security engineer to help teams discover, validate & fix vulnerabilities across modern codebases continuously and at scale.

Think about what this unlocks 👇 • Open-source tools can now monetize via usage. • Indie devs can publish APIs without Stripe overhead. • SaaS teams can offer granular billing users pay only for what they consume. This is subscriptions → streams for the API economy

Enter x402 Protocol, a layer that lets you charge micro-payments per API call, directly on-chain. No middlemen, no billing dashboards. Just → Call → Verify → Pay. Example: a dev tool or AI agent could earn a few cents every time another agent hits its endpoint⚙️
