Introduction
Crosschain. One word. One ethereum.
First, there was DeFi Summer. Then came NFT Summer and Onchain Summer. But this year, things are getting much more exciting. Welcome to the biggest crypto season yet: Crosschain Summer.
Across is kicking things off with the Crosschain Summer Bootcamp: a curated, hands-on educational experience for anyone looking to level up their understanding of crosschain interoperability. Whether you're a DeFi degen, a curious builder, or someone who just wants to get it, this is your chance to go deep, get smart, and join the wave.
Here's what you need to know.
Key Takeaways
Crosschain Summer is a movement to educate and empower Ethereum’s community around the future of interoperability.
The Crosschain Summer Bootcamp is a free, one-week program that teaches the fundamentals of crosschain architecture, bridging, and intents.
Complete the bootcamp and pass the exam to unlock guaranteed entry into the Across Ambassador Program, unlocking opportunities to contribute, earn, and lead in the interop space.
What is Crosschain Summer?
Crosschain Summer is a season-long tribute to the spirit of open collaboration, education, and innovation that has fueled Ethereum’s biggest growth moments. Inspired by Base’s Onchain Summer, we’re taking that same energy and pointing it toward the next frontier: seamless crosschain coordination.
At its core, Crosschain Summer is an invitation to the entire Ethereum ecosystem to come together and understand what makes crosschain tech work, where it’s going, and how we can all play a part in making it better. By fueling an ecosystem-wide celebration of interoperability, we aim to empower the Ethereum community with the knowledge, tools, and momentum to navigate and shape the network’s multichain future.
This is more than just about the vibes. It’s a movement. One that starts with education and leads to action, starting with the bootcamp.
Crosschain Summer is here.
What is the Crosschain Summer Bootcamp?
The Crosschain Summer Bootcamp is your guided path into the crosschain future of crypto. It’s a one-week, self-paced journey designed to give you the foundational knowledge, hands-on exposure, and community support to start thinking like a crosschain expert.
Understanding interop is essential, and the more people who get it, the better off Ethereum will be. So our goal is to make sure that you have the tools to traverse Ethereum's multichain landscape with confidence.
Note: The Crosschain Summer Bootcamp is a remote event hosted in the Across Discord server.
Why the Bootcamp Matters
Ethereum’s future is modular, and that future demands interoperability.
The Crosschain Summer Bootcamp helps you understand what that actually means. You’ll go beyond surface-level concepts to explore the technical and philosophical foundations of crosschain coordination. You'll learn why bridging exists in the first place, what’s broken, and how protocols like Across are working to fix it.
This is your onramp into the next evolution of Ethereum. And we’re making it accessible to everyone.
What You’ll Get
Over the course of about a week (at your own pace), you’ll dive into:
The foundations of crosschain architecture.
Security models and how trust assumptions impact bridging.
Why Intents, relayers, and capital efficiency set Across apart.
Real-world use cases that show crosschain in action.
Guest sessions from top projects building the future of Ethereum.
No fluff. No filler. Just high-signal education and a direct path to impact.
Crosschain Summer Bootcamp is filled with high-quality curriculum designed to educate participants on crosschain interoperability.
Test Your Knowledge and Earn Your Spot
At the end of the bootcamp, you’ll have the option to take an exam to prove what you’ve learned.
Pass the exam, and you will earn guaranteed access to the Across Ambassador Program: a next-level opportunity to grow as a contributor, connect with like-minded peers, and help shape the future of crosschain interoperability.
This is your chance to turn your newfound knowledge into action and join a growing network of mission-aligned builders across the Ethereum ecosystem.
What Comes After?
Graduating from the bootcamp is just the beginning. As an Ambassador, you’ll get:
Private Discord access and contributor roles.
A chance to receive exclusive Across merch and early invites to events.
A chance to earn monthly $ACX rewards, spot bonuses, and growth opportunities.
Real chances to contribute to content, growth, governance, and business development.
A front-row seat to the evolution of crosschain interoperability.
All we ask is that you show up thoughtfully, contribute creatively, and stay mission-aligned.
Becoming an Across Ambassador unlocks a plethora of opportunities.
