What is the OP Stack?

The OP Stack is a modular, open-source development stack that powers Optimism and other Layer 2 networks. It provides the infrastructure for building scalable Ethereum rollups with shared security and interoperability through the Superchain.

How can you help with my L2 launch?

I provide end-to-end consultation for L2 launches, from testnet to mainnet deployment. This includes technical architecture, go-to-market strategy, user acquisition, and scaling strategies based on my experience scaling Base to $10B+ TVL.

What's your experience with the OP Stack?

I was on the Base Core team at Coinbase, where I helped scale Base from testnet to over $10B TVL. I also serve on Optimism's Developer Advisory Board, giving me deep insight into protocol upgrades and the future roadmap of the OP Stack.

How do I book a consultation?

You can book a 30-minute consultation directly through my Calendly link on the site. For longer engagements or specific project needs, reach out via email at hello@opstack.org or DM me on X @wbnns.

What types of projects do you work with?

I work with teams building on the OP Stack, including new L2 launches, existing chains looking to scale, projects considering migration to OP Stack, and teams needing governance or decentralization strategies.
