It's a wrap on June, and what a defining month for Cartesi. Emergency withdrawals are now live and being tested, tooling got sharper across the CLI, Rollups Node, and Explorer, and new demos and educational resources kept rolling out. Read the full blog ↓
Another Friday, another Cartesi Weekly 🐧 Here's what happened this week:
Rollups Node v2.0.0-alpha.12 is out. The main feature is emergency withdrawal. Authority, Quorum, and PRT applications can now be deployed with a guardian and a withdrawal output builder. For the first time, users can withdraw funds from a halted application and from accounts proven onchain, fully trustless end-to-end. New CLI commands cover the full lifecycle, and JSON-RPC adds ‘cartesi_listWithdrawals’ and ‘cartesi_getWithdrawal’. Full CLI walkthrough in the #rollups channel: → discord.gg/cartesi
The release also ships Cartesi Machine emulator 0.20.0. This version is for core devs and testers, so any feedback is welcome. See the full release notes: → https://github.com/cartesi/rollups-node/releases/tag/v2.0.0-alpha.12
On the DeFi front, we started the conversation on why DeFi needs an operating system like Linux and what the benefits are for builders. Give it a read. 10 reasons DeFi needs Linux onchain: → https://x.com/cartesiproject/status/2067246406763704757
DevRel lead Joao Garcia broke down what Cartesi changes for DeFi across three levels: for a kid, an engineering student, and a PhD. DeFi has always been about approximation (Black-Scholes, Monte Carlo, logistic regression) to fit a gas budget. Well, that doesn't need to be the case anymore: → https://x.com/joaopdgarcia/status/2067601502110179709

Joao also joined the ChainPatrol podcast this week. Insightful conversation and a big shoutout to the hosts for having us. Check it out: → https://x.com/ChainPatrol/status/2067684135515336752
Thank you to everyone who filled out our survey. You made your voice heard and your feedback matters. For the lucky ones, merch packs will be heading your way. You know the drill: unbox on socials for everyone to see.
That's a wrap, folks. Slide into the weekend in style and never stop building!
Our technical milestones are making it into L2BEAT monthly recaps, the go-to source for onchain transparency across the ecosystem. Worth reading through. ↓ https://l2beat.com/publications/monthly-update-2026-05
A reminder that every contribution matters, whether you’re building, researching, testing, creating content, engaging with the community, or simply asking thoughtful questions.
Open-source software is built together. So is Cartesi.
Last month brought a lot to catch up on. Dive into the latest ecosystem updates for tech releases, agentic dev tooling, DeFi demos, media highlights, and community news. ↓
Food for thought and good reading for the weekend.
Cofounder Erick de Moura on why Ethereum's real crisis isn't organizational but mythological, and what that means for every builder who has ever asked whether the hardship is worth it. Dive in ↓
Just in: contributors shipped an MCP server for Cartesi development. If you build on Cartesi with AI tools like Claude or Cursor AI this changes your experience.
Pair it with the skills and you have no excuses not to start vibe-coding today.
With the MCP server connected, your AI agent gets the right CLI commands, step-by-step skills for local dev, frontend, backend, asset deposits, L1 interactions and onchain deployment, plus docs, repos and articles by topic. All inline, no external fetches. https://server.mcp.mugen.builders/mcp
Time has come to say goodbye to hallucinated CLI commands, missed version details, and gaps in Cartesi-specific knowledge.
Resources are live and growing. Building on Cartesi has never been easier. Explore here: https://github.com/Mugen-Builders/MCP-Server
Our DevAd Lead Joao Garcia will be joining a panel on the House of Chimera space this Friday, May 22, to unpack AI beyond the hype alongside other industry players.
Expect sharp takes on where AI x Web3 is going.
