Introducing Arbitrum Vibekit & the Trailblazer Fund 2.0

TL;DR

Building DeFi agents shouldn’t be a maze of tools, protocols and frameworks. With the Arbitrum Vibekit we’re making it radically easier for developers to build, test, run, and deploy DeFAI applications and agents that actually get things done, without reinventing the wheel each time.

Think of Vibekit as your starter kit for vibecoding powerful, flexible agents and workflows — whether you’re automating trades, managing liquidity, or experimenting with new UX ideas.

Use the light MCP-and-A2A based framework, the growing list of templates, web3-ready frontend, library of web3 MCP servers, and the onchain execution brought by Ember's intent-based MCP servers for a plug-and-play experience.

And to kick things off, Arbitrum is backing the launch with Trailblazer Fund 2.0: a $1M retroactive funding program focused on rewarding impactful DeFi agents, agent templates, and core contributions to the Vibekit framework. Check out the bounty board here

Vibekit — built and powered by Ember AI

Arbitrum Vibekit is an open-source framework for building DeFi agents that run on your machine, with your strategies, with fast and low-cost transactions powered by Arbitrum. It’s modular, production-ready, and built to plug into the Arbitrum DeFi ecosystem out of the box.

With Vibekit, you can:

• Customize plug-and-play templates to get from idea to working agent fast.
• Build agents using your private workflows and interact with DeFi protocols in real time.
• Deploy agents that talk to other agents, access off-chain data, and trigger actions, without needing to worry about anything beyond your strategy.
• Tap into powerful open standards like MCP, A2A, 402x, and in the next two weeks, Pectra.
  

Trailblazer Fund 2.0

As part of this launch, Arbitrum is introducing the Trailblazer Fund 2.0, a $1M initiative to support early contributions to Vibekit.

The goal is simple: support useful work that helps expand the agent ecosystem. This includes building agents, improving the developer experience, or connecting Vibekit to new tooling and DeFi protocols on Arbitrum.

We’re particularly looking for:

• Agents implementing profitable strategies in Arbitrum DeFi
• Frontend improvements or dashboards for running agents
• Contributions to the framework
• New tools or modules others can reuse
• Integrations with other agent frameworks or toolkits

See the Bounty Board here

Retroactive rewards that will be prioritized currently includes:

• Templates that execute complex DeFi strategies
• Open source contributions that expand the utility of the broader Vibekit agent ecosystem
• Frontend components such as trading history for Vibekit agents, PnL calculation, etc
• The creation of a backtesting suite for Vibekit agents

If you’re building something useful, or planning to, you can apply now.

What's Coming Next

We’re just getting started. In the coming weeks, you can expect:

• New agent templates and examples of DeFi strategies ready for production
• Deep integrations with more popular Arbitrum dApps and systems
• Support for more hybrid agent interfaces and AI UX flows
• Community bounties, workshops, and hackathons powered by the Trailblazer Fund
• Better docs, clearer guides, and smoother onboarding for new users and tools for developers
