Incredible! 🇺🇸🫡 American jet evades Iranian Shahid missile on February 28th surprise attack!



We’re down to just a few points left. We should have Clarity signed into law “within a few months.” ⏳⚖️🇺🇸


1/ Custodial wallets are live in Privy. Built to serve global businesses that desire a licensed custodian partner, clearer recovery paths, and institutional controls. After powering 120M+ wallets & $9B+ in monthly volume, we know custody must adapt to real-world requirements.



Big day for the Superchain. 🔴✨ We’re integrating ZK more deeply into the OP Stack, and are excited to announce that @SuccinctLabs is our first preferred proving partner in this area. Validity proofs are going — and withdrawals are about to get faster. Here's what that means. ⸻ THE 7-DAY PROBLEM Optimistic rollups have a 7-day challenge window. Anyone can challenge a bad state transition during that period. For most users, this is abstracted away with app-layer bridges. For institutions? Different story. Custody providers can't lock capital for a week every time they move funds off L2. Market makers need capital efficiency across positions. Treasury teams need faster withdrawal finality that matches traditional infrastructure expectations. The 7-day window was always a tradeoff. Now we're addressing it. ⸻ ZK CHANGES THE MATH With validity proofs, we don't wait for challenges. We prove the state transition cryptographically. When the proof verifies on L1, the withdrawal is final. The goal: instant, real-time withdrawals. ⸻ WHY SUCCINCT Their proving system works — fast proving, low costs, compatible with our existing architecture. @SuccinctLabs secures billions in TVL across the ecosystem. OP Succinct, their proving engine for the OP Stack, is a drop-in upgrade. Deploy one smart contract, spin up a lightweight proposer service. Everything else — sequencer, batcher, op-node — stays the same. We built the OP Stack to be modular for exactly this reason. ⸻ THIS ISN'T ABOUT CHEAP TRANSACTIONS L2s were never just "cheaper Ethereum." That framing missed it. The best Superchain deployments aren't discount L1s. They're doing things L1 structurally can't: * Sub-200ms blocks for real-time apps * Embedded distribution (Base: 110M Coinbase users) * Custom sequencing for specific use cases * Native identity infrastructure (World Chain) * Exchange-integrated DeFi (Ink) These bring real users, real distribution, real use cases that didn't exist before. ZK validity proofs unlock real economic efficiency for users & institutions. ⸻ WHAT THIS UNLOCKS * Custody providers can move client assets without locking capital for a week * Market makers gain capital efficiency across L2 positions * Treasury operations get faster withdrawal finality, matching expectations from traditional infrastructure ⸻ MULTI-PROOF FUTURE This is step one. The vision: OP Stack chains choose the prover networks that fits their needs. Different security tradeoffs, different cost profiles. Modular infrastructure, sovereign choices. After ZK goes live on OP Mainnet, every OP Stack chain can upgrade seamlessly. We’re bringing fast withdrawals with strong cryptographic security to the Superchain! ⸻ The OP Stack was designed for this moment! ZK for your Blockchain. Your Revenue. Enterprise Guarantees. Thanks to @SuccinctLabs and @pumatheuma for building what we needed. Full announcement: optimism.io/blog/optimism-…

Hinkal has integrated with @arc to enable confidential stablecoin transfers for enterprises moving treasury operations onchain. Private Send allows institutions to leverage Arc’s next-generation stablecoin infrastructure without exposing sensitive financial activity. Execution Flow: - Securely connect any existing wallet at send.hinkal.io - Enter the recipient’s public address. - Complete a confidential stablecoin transfer with one click. Configurable payout controls allow institutions to define how and when funds are delivered, further reducing on-chain visibility. - Split transfers: Distribute a single payment across multiple recipients - useful for payrolls and vendor payments - or break it into multiple smaller payouts to the same address. This limits transaction aggregation and keeps treasury-to-counterparty relationships private. - Scheduled transfers: Select a delivery window rather than sending immediately. Transfers are executed at randomized times within that window, preventing correlation between transaction initiation and receipt. Hinkal leverages Zero-Knowledge (ZK) technology to validate transaction integrity and proof of funds without ever accessing or storing user financial data. One-click privacy, as it should be!
