We are excited to invite you to join us for another Web3 Devs Underground event! 🔐₿ Two sessions. Two frontiers. One event. @Web3_Devs × @zama x @RitrekRecovery powered by @MasterkeyVC 📅 March 11th | 17:00 Israel Time | 16:00 CET | 10:00 EDT 📍 Live on X, YouTube & LinkedIn Register Here: luma.com/78qezjr0 Session 1 - FHE & Confidential Smart Contracts @poppyseedDev (Aurora Poppyseed), DevRel at @zama, breaks down how Fully Homomorphic Encryption (FHE) is bringing real confidentiality to the EVM - running computations on encrypted data without ever decrypting it. From private transfers to blind auctions, this is what on-chain privacy actually looks like. Session 2 - TimeLock Recovery for Bitcoin Backup @oren_z0 (Oren Zomer), Founder at @RitrekRecovery, walks through structured wallet recovery using Bitcoin Script - primary to secondary wallet, and what BIP-128 makes possible. Self-sovereign custody, done right. Two of the most technically dense topics in crypto infrastructure - in one session. Whether you're building on EVM or working with Bitcoin Script, this one's for you. 🔗 See full calendar: lnkd.in/dPBqaEMc @MasterkeyVC @SHAP0W @Amit_Masterkey @Web3_Devs @ELuttenberg789 @AlonKivity @al23xyz #Web3 #Bitcoin #FHE #Zama #ZeroKnowledge #BitcoinScript #Cryptography #Web3Dev #Blockchain #DeFi #SmartContracts #MasterkeyVC

@AkashMVerma1 @0x4Mica Amazing!!!

Coinbase just gave agents wallets. But wallets don't solve the real problem. AI agents will execute millions of micro-actions per day. No blockchain, no matter how fast, can handle a separate on-chain transaction for every single one. We built @0x4Mica. Agents transact instantly with cryptographic guarantees, and settlement happens later in batches. Thousands of micro-payments, one on-chain transaction. In this demo, I'm streaming a video, and each data chunk is paid for in real-time. Watch what happens when I switch from 4Mica credit to raw on-chain payments, and then ask to be switched back. Same stream. Same operator. Completely different experience.
