AI agents are signing transactions, holding keys, and moving real funds, usually with no guardrails at all. That's a brand-new attack surface, and your current security model wasn't built for it. Join us THIS WEDNESDAY for a deep technical session on securing autonomous agents, with Kevin Jones (@cryptomastery_), founder of @1clawAI and DevRel at @edgeandnode / @graphprotocol. What we're covering: • Why AI agents are a new class of attack surface • Giving an agent a leash (policy enforcement), a wallet (HSM-backed key custody), and a safety belt (pre-execution guardrails) • How @1clawAI secures the agent economy at scale • Practical patterns for builders shipping agents that touch real funds 🗓 Wednesday, June 17 🕔 17:00 IDT | 16:00 CET | 10:00 EDT 📡 Live on X, YouTube & LinkedIn If you're building or deploying onchain AI agents, this one goes straight to the core.

Two years ago, we started with a simple question. What will it take to simplify the integration of blockchain primitives with global financial rails? Today we’re launching LI.​FI Intents to help make that possible for every business in the world. A product we know this industry needs, a product we’ve built to solve some of the biggest challenges global fintechs face as they move into digital assets, a product we believe companies don’t need tomorrow, or even today, they needed it yesterday. How do we enable stablecoin payments? How do we unlock access to real-world assets for our users? How do we ensure we only touch compliant liquidity across blockchains? These are some of the biggest questions leadership teams across fintech are asking themselves right now. They’re the same questions we asked ourselves. And we knew they had to be solved. LI.​FI Intents is our answer. Every touchpoint of the stack is modular. The entire product is fully customizable to fit ANY business need. From the order type, to who the market maker can be, to how the transaction will be settled on blockchains, to which service providers your business trusts - everything can be shaped around how you want your product to work. As a builder myself, this is the kind of flexibility and abstraction I’ve been looking for in this industry ever since we started LI.​FI 5 years ago. And I’m incredibly proud that the LI.​FI team is delivering it. LI.​FI Intents is built to make crypto products easier to launch for businesses that want to move onchain, but have been slowed down by the complexity of it all. The enterprise stack for onchain finance. For all intents and purposes.

Top builders are in…

.@FarroYossi says " Every single venture firm should have an office in Israel." "I think one person really missing out on Israel right now is @a16z." "I'm calling out a16z. I think you guys should open up a venture firm in Israel this year." "Shabbat Shalom."

We’re pleased to welcome @SHAP0W , Managing Partner at @masterkeyvc , as a speaker at the Tokenized Capital Summit 2026 in Miami 🇺🇸 Shauli will share how emerging ecosystems are identified before they break out - covering founder-market fit, timing cycles, and how capital is positioned ahead of narrative shifts in crypto.

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

Code is not a crime

Some of our best hires were totally unqualified on paper. They always had the same qualities: entrepreneurial, high agency, smart, mission aligned, and they got shit done. If you’re hiring, especially in early stages, seek out & bet on these people. Don’t over-index on resumes.

Payroll is one of the most sensitive operations in enterprise finance. Today, we're bringing it on-chain, without compromising privacy or compliance. Ligero is live as an L2 on @EspressoSys, with on-chain payroll as our first production use case. We didn't build around the problems enterprises face, we solved them. Private salaries, instant stablecoin settlement, and regulatory compliance that's cryptographically guaranteed, not manually managed. And it all works within the tools and workflows your teams already use. Espresso is running it for their own employees, validating the system in a real, high-stakes environment. That's proof, not a promise. Dive deeper into how we built it👇 pages.ligero-inc.com/ligero-…

See you soon!

Working in crypto requires knowledge in cryptography, economy, finance, game theory, politics, and sociology. All these fields are in motion 24/7. Maybe people are leaving crypto because they need a bigger challenge

Today, Y Combinator is announcing that YC-funded startups can choose to receive their funding ($500k) in stablecoins. We believe stablecoins like @usdc are setting the stage for a new fintech renaissance and broader global access to financial services. Sending money should be as easy as sending a text message. Stablecoins make that possible: cheap, fast, and global, using currencies people already trust. Some of the fastest-growing YC startups in recent years like @get_aspora and @DolarApp use stablecoins to power faster, cheaper financial services across India and Latin America. Plus, with the passage of the GENIUS Act and growing adoption by financial institutions, we’re bullish. Whether crypto-focused or not, we expect many YC startups to use crypto in some way, from payments to banking to capital raising. If you’re building onchain, apply for our Spring ‘26 batch by Feb 9: ycombinator.com/apply

the agent ecosystem is exploding rn @bankrbot started the on-chain wave @moltbook became Reddit for agents (1.2M registered) now we've got pinchsocial.io as Twitter for agents agents building tools for agents humans just watching 2025 was humans using AI 2026 is AI using the internet

WhatsApp is not secure. Even Signal is questionable. Use 𝕏 Chat.

The Iranian Regime just projects their own strategy on Israel “Whose payroll are you on??” - Iran finances multimillion dollar internet astroturfing campaigns and bot networks “Israel’s genocide of Palestine” - Actually, it’s a war against Hamas who invaded their land. It’s the Islamic Regime that’s committing mass murder against a group of indigenous people - the Iranians “Zionism” - Actually, Judaism is the one religion that just wants to be left alone. On the contrary “Islam” is a religion that wants to totally dominate world and will do so by any means necessary. The narrative of the Islamic Regime simply takes its own strategy, and projects it upon Israel and psyops the west into believing it.
