    $3.1B gone. 69% from wallets. 17% from phishing, and 2025 isn’t even over yet. The biggest Web3 breaches this year didn’t come from broken blockchains - they came from how we build, sign, and govern around them. From Bybit's $1.5B cold wallet exploit (a UI-level attack on Safe{Wallet}) to the Cetus overflow bug on Sui Foundation - every case exposed the same flaw: even perfect code can fail when the system around it isn’t. So what actually went wrong? • JavaScript injection on multisig UIs • Reused math libraries in Move • Human approval chains with no policy guardrails Dive into the full breakdown: https://lnkd.in/gxuS2m6d

  • Most devs don’t struggle with code - they struggle with go-to-market. You can build something incredible, ship it, polish it, and still fail to find users. Squads proved there’s another way. Instead of chasing hype, they built a product so strong it marketed itself through Product-Led Growth. Look at where they are now: Top Solana projects like Jupiter, Drift, Pyth Network, Raydium Protocol, and Helius rely on Squads to safeguard their most sensitive assets - treasury, upgrade authority, and token minting. Each integration reinforces trust. Each user validates the product. Together, they’ve turned Squads into the security backbone of the Solana ecosystem - built not through hype or tokenomics, but through product excellence and open-source credibility. If you’re building in Web3, this story will change the way you think about go-to-market: https://lnkd.in/g_eFWnXt

  • Sometimes, not winning is just the beginning. That’s how Squads started - co-founded by Sean Ganser and Stepan Simkin. They didn’t win anything at the Solana Season hackathon. No token. No airdrops. No fancy marketing. Just pure, trust-first building. Fast forward to today, Squads secures over $10B+ in assets for some of Solana’s biggest projects. If you’ve ever asked yourself: - How do you market a product with a lean budget? - How do you build something people actually want to use? - How do you create long-term trust without hype? Then the story of Squads is your blueprint. Dive into Part 1 of our deep-dive series: https://lnkd.in/gsETdi9V   What’s one thing you think Web3 founders often overlook when building trust? Would love to hear your take 👇

  • Is RWA tokenization just a hype cycle? Or a real opportunity for success? If you follow the digital asset space, you've heard the skepticism: adoption is slow, most projects are just pilots, and the real-world volume is tiny. This skepticism is valid. The bottleneck holding back the trillion-dollar RWA opportunity isn't the vision; it's the lack of institutional-grade security infrastructure. In 2025 alone, over $2 billion has been lost to hacks, with private key compromise being a primary culprit. For institutions, this level of risk is unacceptable. To unlock the potential of RWAs, we must solve this billion-dollar security flaw. While traditional multi-sig wallets offer a partial solution, they lack the flexibility and scalability required for a multi-chain, institutional world. The real architectural shift is Multi-Party Computation (MPC) - a cryptographic system that eliminates the single point of failure by removing the concept of a "master key." It enables organizations to create highly flexible, off-chain security policies that mirror their internal governance. In our latest article, we break down the entire RWA infrastructure stack, from issuance to custody, and make the case for why a MPC wallet infrastructure is the key to moving beyond hype and into reality.

    What if deploying a Self-Hosted Stablecoin Custody Platform took One Command Line instead of one month? The Fystack team is excited to introduce Fystack Ignite - an open-source project that lets anyone self-host a #stablecoin #custody platform that’s secure, transparent, and cost-efficient without hiring a full devops team or paying for complex infrastructure. With just one command `./fystack-ignite.sh` you can launch a multi-chain custody system supporting Ethereum, Solana, Tron, BSC, Polygon, and more - in minutes, not months. Why Fystack Ignite? • Open Source & Transparent – full control over your data and security. • Multi-Chain Ready – scale your custody infrastructure across multiple blockchains without limits. • Simple & Cost-Effective – one command, zero devops hassle.  Walkthrough demo:: https://lnkd.in/g5Swgp35

  • Wallet compromises made up 23% of total crypto crime losses ($2.47B) in H1 2025 with Solana Foundation being the prime target, fueled by the memecoin hype. Everyone’s chasing 10x with $WIF, $BONK, or $POPCAT. But one malicious link, fake airdrop popup, or rogue dev can drain your wallet in minutes. We’ve seen it happen again and again. That’s why you need more than just caution - you need self-custody with control! With a self-hosted MPC wallet, you can define rules, set alerts, and block suspicious transactions before it’s too late.

    We know the pain of digging through endless logs just to debug a webhook. Sometimes it takes hours. That’s why we built Webhook Dashboard - a place where you can track every delivery with complete insights. Now it only takes 5 seconds to see: • HTTP status codes • Response details • Overall performance And if something goes wrong, you can retry failed webhooks instantly. Faster, simpler, and so convenient you’ll wonder how you ever worked without it. Check out the Dashboard ↓ https://lnkd.in/gVY75j7k

  • We keep hearing it from devs and users: “we need better wallet monitoring.” Yet most custodians and wallet providers still don’t offer it. For us, that’s essential. So we made it real. Advanced Monitoring is now live on Fystack. Get instant Telegram & Slack alerts for deposits, withdrawals, approvals, and balance thresholds. How it works ↓
