Seems like @RobinhoodCrypto is winning the race!

I guess these shielded pools, specially the permission-less ones and the ones that work with ZKPs will be the new haven for blackhats. New technology not much standards behind it in the industry yet and everyone uses a new implementation.

I just reserved my Cloudflare Wallet tag: 4rdii.cloudflare.pay. Reserve yours now at cloudflare.pay

Similar setup. BTC weathered that storm and will weather this one too.

Was it just me, or did everyone else also think embedded @privy_io wallets always had a recovery mechanism in case the integrating app went down? Given how their model works, I assumed there would always be a way for users to recover their wallet if an app shuts down and they hadn't exported their private key or seed phrase beforehand.

Here we go, another million-dollar marketing scheme by solana:pumpCmXqMfrsAkQ5r49WcJnRayYRqmXz6ae8H7H9Dfn to bring people back to its platform. And from the trading volume, it seems their mission was accomplished

One way I can see the $SPCX IPO and the whole US stock market going is that the SpaceX IPO will become quite a success earning retail a shit ton of money, but then on the upcoming Anthropic and OpenAI IPOs they're going to dump everything on retail to compensate their credit risks.

The CTF contract is not exploited, it’s an internal address we use for ops. POL was being sent to that address because it was in an internal refiller service that checks and refills balances every couple of seconds. All user funds are safe and the address is being rotated.

🔐 What if you could prove your trading strategy was profitable — without revealing the strategy itself? zkBacktest is live on my GitHub. Here's what it does. 🧵 --------------------------------------------------------- TL;DR ✅ 📊 Prove correct backtests of trading strategies over committed price data 🔒 Keep your strategy private — nobody sees your Pine Script ⚙️ Two proof backends: Winterfell AIR (custom STARK) + RISC Zero zkVM ✨ Blake3-committed dataset — no cherry-picking bars 🧮 In-circuit financial metrics: total return, Sharpe ratio, max drawdown 🚫 No-look-ahead enforced as a circuit invariant --------------------------------------------------------- 🔍 What is zkBacktest? You write a trading strategy. You run it against historical price data. You get a ZK proof that says: "This secret strategy, on this exact public dataset, produced these exact results." No trust needed. No fake backtests. No reveal of your strategy. Just math. --------------------------------------------------------- ⚔️ Why it matters: Backtesting has a credibility problem. Anyone can show you a pretty equity curve and claim their strategy worked. Without verifiable execution, it's hard to know what's real. zkBacktest addresses this directly: The proof commits to the dataset via #Blake3. The circuit enforces causal order: bar `t` cannot see bar `t+1`. Cherry-picking is structurally impossible. --------------------------------------------------------- ⚙️ How it works — two backends: Phase 1,2: #Winterfell AIR (#STARK) Custom STARK over the Goldilocks field. Strategy parameters are public. The AIR circuit verifies prices, positions, returns, and drawdown peaks across the trace. All constraints are degree ≤ 2. Phase 3: @RiscZero zkVM A #PineScript subset interpreter runs inside a zkVM. Strategy is private witness. Only the public journal is revealed: total return, Sharpe, drawdown, dataset, and its commit. The verifier cannot see your strategy. That's not a feature; it's a cryptographic guarantee. 🔒 --------------------------------------------------------- 🧩 The interesting part: No-look-ahead isn't enforced by convention; it's a circuit invariant. You cannot encode a look-ahead bug. The circuit won't allow it 🙅‍♂️ And the dataset commitment? Blake3 hash of every bar, in order. Swap one bar: proof breaks. --------------------------------------------------------- 🚀 Why this matters long-term: On-chain strategy marketplaces where sellers prove performance without revealing alpha. DeFi vaults that publish verifiable backtests before accepting capital. Quant funds where "here's a ZK proof" replaces "trust me." ZK applied to finance is still early. But the primitive is here. --------------------------------------------------------- Would you use something like this to verify a strategy before trusting a vault?

🤯CODE4RENA SUNSETTING. THE END OF AN ERA Thank you for everything, code4rena, forever in our hearts <3

1 year ago, I made a video about how blind signing would cause massive pain. Since then, we've seen hack after hack (recently, Drift protocol for almost $300M), where clear signing could have helped mitigate. Today, we finally have a systemic upgrade to wallet UX 👇
