Perp DEXs are quietly winning the most important battle in DeFi. On-chain perps already do billions in daily volume and they're capturing it without custody risk, without KYC walls, and without a CEX deciding what you can trade. The infrastructure finally caught up: low-latency orderbooks, deep liquidity layers, cross-margin, sub-second execution. The "CEX UX, DEX trust" gap is closing fast. The next cycle won't be about whether perp DEXs can compete with centralized venues. It'll be about how much share they take. Self-custody leverage permissionless markets is a hard combination to bet against.

Castrum Capital is live in Bangkok 🇹🇭 Great energy, great people, and proud to be part of this amazing side event as an ecosystem partner.

We’re happy to share that Castrum Istanbul (@castrumistanbul) has joined the 2U2.ai journey as a strategic investor 📢 At 2U2.ai, we’re focused on exploring the future of AI-powered meme creation, remix culture, and viral storytelling within Web3.

🚀DAOKraft has raised $3.4M in private funding. Backed by Animoca Brands, Castrum Capital, Nodebase, Moniq Ventures, Blockwave Capital, and Mesh Fund. Building the Governance Intelligence Layer for DAOs — helping contributors make better decisions before voting. More soon.

Turkey processed $200B in crypto volume in 2025. 🇹🇷 Istanbul isn't a bridge between East and West anymore. It's the operating center for the next generation of Web3 capital. We've been building here since 2021. This city chose us back.

Most VCs write a check and disappear. 💸 We write a check. Then marketing, KOL distribution, guild activation, talent pipeline. Capital is where the relationship starts. Not where it ends.

Investing in Turkiye's crypto market isn't just a geographic bet. It's a macro hedge. Inflation forces adoption. A population that uses crypto to survive is more durable than one that uses it to speculate. 📈

We’re proud to announce that Castrum Capital is strategically supporting the @OriginsNetwork_. Looking forward to contributing to its growth and journey ahead.
