Cuckoo Chain began as an audacious bet: that a small team and a global community could prove on-chain AI workloads at scale. Together, we did exactly that. Today we’re announcing that Cuckoo Chain is entering sunset mode, and we want to share not only the logistics but the lessons that will guide our next chapter.
This isn't a story of failure, but one of evolution. We set out to explore a new frontier, and the knowledge we brought back has illuminated a much clearer path forward. We’re immensely proud of what we built and even more excited for what comes next.
What We Achieved
The Cuckoo Chain experiment was a resounding success in demonstrating real-world engagement with on-chain AI. The numbers speak for themselves:
- Peak Daily Transactions: 300,000
- Lifetime Transactions: 888,884
- Unique Wallet Addresses: 57,089
These aren’t just vanity metrics. They represent the collective curiosity and creativity of real developers, artists, and tinkerers who stress-tested our Layer 1 network. They minted AI-generated art, deployed experimental smart contracts, and showed the world a glimpse of what permissionless AI can look like. For that, we are eternally grateful.
Sunset Logistics
Effective immediately, we are beginning the sunset process for the Cuckoo Chain. Our priority is to make this transition as smooth as possible for our community. Here is what you need to know:
- All core network services—including the public airdrop portal, staking and mining rewards, the cross-chain bridge, and the official block explorer—will be brought offline.
- The chain will be finalized at a specific block height, after which no new blocks will be produced. All on-chain activity and smart-contract execution will cease.
- We believe in the permanent value of open data. A full historical node dump, CSV exports of on-chain activity, and checksums for verification are available upon request. Please contact us at hello@cuckoo.network to receive a copy.
Why We’re Sunsetting
When we started, building a bespoke Layer 1 was the most direct way to achieve our technical goals. The landscape has since changed dramatically. In 2025, the rise of shared-security layers like EigenLayer AVSs, the OP Stack, ZK Stack, and various Hyperchains offers a new paradigm. These platforms deliver stronger economic guarantees, deeper liquidity, and a significantly lower operational burden than a stand-alone chain can realistically match.
Continuing to operate Cuckoo Chain would mean diverting resources to infrastructure maintenance instead of innovation. Shutting down the L1 is a strategic decision that lets us focus every dollar and every engineer on what matters most: building user-facing AI products that solve real problems.
What We Learned
Running a public blockchain in the wild was an invaluable learning experience. We’re sharing these lessons in the spirit of transparency and to help other builders in the space.
-
Throughput ≠ Product-Market Fit We successfully scaled to handle high TPS, but without a single, must-have application, much of that activity consisted of users looping assets through faucets to farm rewards. High throughput is a means to an end, not the end itself. Durable demand comes from utility, not just capacity.
-
Incentives Must Map to Utility Our airdrop and high-yield staking programs were effective at attracting an initial wave of users. However, these incentives primarily attracted opportunistic wallets that had little retention once the rewards tapered off. Future tokenomics must be directly tied to genuine product usage, not just passive holding.
-
Infrastructure Costs Compound The financial and human costs of maintaining a secure L1 are immense. Validator coordination, bridge security, continuous bug bounties, and third-party audits quickly consumed six-figure budgets. This capital is far better spent on developing the core AI features that differentiate our product.
-
A Fragmented Dev Experience Hurts Growth By creating our own environment, we introduced friction. Developers are accustomed to the mature tooling of EVM or the modularity of the Cosmos SDK. Our custom RPC quirks and missing libraries raised the barrier to entry, slowing down the organic growth of our developer ecosystem.
-
Security & Compliance Overhead Scales Non-Linearly Every new bridge or integration didn't just add to our security burden—it multiplied it. Each connection point became a new potential attack surface and introduced another layer of regulatory complexity, demanding constant vigilance and resources.
How We’ll Do Better Next Time
Our experience with Cuckoo Chain has given us a clear playbook for the future. We are not pivoting away from our mission but refining our strategy to execute it more effectively.
- Build on shared security, not against it. Our future services will launch as rollups or actively validated services (AVSs) that inherit consensus, bridges, and liquidity from established ecosystems like Ethereum.
- Lead with a flagship use case. We will dog-food our own technology, starting with our intent-centric AI coaching quests. This will show developers why they should build with us, not just how.
- Align tokenomics with real workload demand. We are moving away from blanket airdrops and toward revenue-share models and token rewards tied directly to usage metrics and service-level KPIs.
- Prioritize developer ergonomics. We will provide EVM-equivalent RPCs, comprehensive TypeScript SDKs, ready-to-use Hardhat and Foundry templates, and first-class documentation to ensure a frictionless developer experience.
- Practice progressive decentralization. We will start with a focused product, publish a clear roadmap for open governance, and keep sunset procedures documented from day one. Planning for every stage of a project's life cycle is a mark of maturity.

A Heartfelt Thank-You
This journey was only possible because of our incredible community. Whether you spun up a validator in the early days, minted your first AI collectible, reported a gnarly bug, or joined a late-night debate on Discord, you made Cuckoo Chain what it was. We are deeply grateful for every transaction, every pull-request, and every ounce of support you gave us.
We’re not slowing down—just shedding the parts that no longer serve the mission. Stay with us; the next chapter will move faster and reach farther.
