Not an IDE. A workspace.

Cursor changed how code gets written. Cowork mode changed how AI works — a real workspace where skills, tools, and connectors work together to get things done. Matterhorn 2.0 is that, built for Web3.

A marketplace of 100+ open-source Web3 skills. Every major protocol integration, deployment tool, and auditing framework — plug-and-play, written and maintained by us. One wallet for 20+ chains, all payments. Agents that build while you sleep. Sync your progress to Notion, Trello, Slack. If a connector doesn't exist yet, we'll build it.

Describe what you want — “build me a staking dashboard for Ethereum and Base, synced with my Notion board” — and the agents get to work. Contracts written and audited. Frontend built with wallet integration. Deployed across chains with gas optimization. Progress synced back to your tools. You come back to a working application.

One wallet. 20+ chains. All payments.

Right now, building across multiple chains means managing multiple wallets, gas tokens, RPC connections, and subscriptions scattered across the internet. Matterhorn collapses all of it.

Deploy to Ethereum. Bridge to Arbitrum. Pay for decentralized compute. Access cross-chain messaging. All from one wallet, one balance. No manual bridging. No subscriptions.

DePIN by default.

Every Matterhorn app ships to DePIN out of the box. Decentralized compute, decentralized storage, and decentralized indexing are all options — you choose the providers that fit your stack. No toggle, no premium tier, no opt-in checkbox — the default is the decentralized path. Because that is what “Web3” should mean, and because your users deserve infrastructure that isn't a single rug-pull away from gone.

You can still deploy to a classic cloud if you want to. That is a conscious choice you make, not a default you inherit.

UserShips it

Ship things people can trust.

Unlike a buggy web app, a vulnerable smart contract can drain wallets with no recourse. A reentrancy exploit doesn't give you time to push a hotfix. The builders who win in Web3 are the ones who ship things people can trust — not just things that came out fast.

Vibe-Audit is built into Matterhorn 2.0 from the start: AI security analysis trained on 100+ real audit reports, with human-in-the-loop review before anything ships. Not a feature we added. The architecture.

Universal Chain Abstraction

One wallet, one interface, 20+ chains. Deploy everywhere with a single command.

Crypto Cowork

The full agentic platform for building anything in Web3, not just an IDE.

One subscription. Pay for Matterhorn credits, use all our features. No protocol wiring, no wallet juggling, no surprise bills.

Who this is for.

The solo founder with a DeFi idea and no Solidity experience.

The Web2 developer who wants to add blockchain features without a six-month detour.

The experienced Solidity engineer who wants to automate the boilerplate and focus on the architecture that matters.

The enterprise team building supply chain, identity, or compliance solutions on a regulated stack.

Why we're not racing to ship code faster.

There's a crowded field of tools promising to generate smart contracts from a chat prompt. Most are racing to ship code fastest. That's the wrong race.

The builders who win in Web3 are the ones who ship things people can trust. The teams who go the distance are the ones whose workspace composes — where the chain, the wallet, the audit, the frontend, and the ops tooling all live under one roof.

Matterhorn 2.0 isn't a faster code generator. It's the workspace that makes building in Web3 feel native instead of fragmented.

Launching May 12. Get in early.
