Solving The Extensibility Problem with Griffin Dunaif of Halliday

In today’s piece, we’re taking a closer look at Halliday, a project that’s working to simplify and automate one of the most crucial yet complex aspects of DeFi—commerce across multiple chains.

Led by Griffin Dunaif, Halliday is focused on building the infrastructure that enables seamless value exchange between different blockchain networks, tackling the challenge of automating asset transfers, on-ramping fiat, and bridging the gaps between L1s, L2s, and L3s.

Commerce Automation is rooted in the idea that digital spaces—much like cities—require a balance of culture and commerce to thrive. While the blockchain world has no shortage of vibrant communities, the infrastructure to support efficient, automated transactions across chains is still in its early stages. Halliday is stepping in to address this gap by automating these processes, making it easier to transfer assets, manage liquidity, and integrate fiat into onchain systems.

One of the key highlights from Griffin’s vision is multi-chain expansion. With the number of blockchains set to grow exponentially, Halliday is preparing for a future with millions of interconnected chains. The focus here isn’t just on basic interoperability but on automating complex, multi-hop transaction workflows—think of going from fiat to a stablecoin on an L1, bridging to an L2, and then settling on an L3.

Halliday aims to make this process seamless and automated, allowing users and developers to interact with different ecosystems without the usual technical complexities. As they gear up for their protocol release in 2025, Halliday is positioning itself to be a crucial player in the evolving landscape of multi-chain commerce, driving the next phase of DeFi growth.
