An End to a Seven-Year Journey on Mainnet
In a surprising move that highlights the fast-changing dynamics of the Web3 landscape, the core development team behind Harmony has formally proposed shutting down its standalone Layer-1 blockchain network after seven years of operation. Under the newly unveiled proposal, the network’s native token, ONE, will transition from its dedicated blockchain to the Ethereum ecosystem as an ERC-20 token, marking an unprecedented pivot for a prominent alt-L1 protocol.
The proposal outlines a complete sunsetting of the existing Harmony mainnet, accompanied by a final-block snapshot that will determine user balances for a subsequent token airdrop on Ethereum. Rather than maintaining an independent consensus mechanism and validator network, Harmony plans to harness the liquidity, security, and developer ecosystem of Ethereum to launch its next chapter.
Urgent Deadline for Users and Liquidity Providers
A critical component of the sunset proposal is the immediate call to action for active participants, decentralized finance (DeFi) users, and liquidity providers on the Harmony network. Because smart contracts, decentralized applications (dApps), and automated market maker (AMM) liquidity pools will not automatically migrate to Ethereum, users must manually unwind their positions.
Harmony’s team has strongly advised all users to withdraw their digital assets, close out smart contract interactions, and exit liquidity pools prior to September 10. Once the network reaches its final block snapshot, any assets trapped within un-migrated smart contracts or third-party protocols will become permanently inaccessible on the legacy chain.
- Token Snapshot: Balances of ONE will be recorded at the network’s final operational block.
- Ethereum Airdrop: Token holders will receive equivalent digital assets deployed on Ethereum’s ERC-20 standard.
- Contract Unwinding: Users must manually withdraw funds from decentralized exchanges, lending markets, and yield farms before September 10.
- Non-Transferable Infrastructure: Onchain applications, custom tokens, and smart contracts hosted on Harmony will not be ported over by the core team.
Pivoting to the “Remix Economy for AI Video”
The decision to sunset the underlying blockchain architecture is paired with a dramatic shift in strategic focus. Harmony plans to reallocate future token emissions and treasury resources toward an emerging venture dubbed the “Remix Economy for AI Video.”
As generative artificial intelligence transforms digital content creation, the team aims to establish decentralized infrastructure for AI-driven video synthesis, media remixing, and digital rights management. By leveraging Ethereum’s robust smart contract environment, the reimagined project seeks to align token incentives with AI content generation, viral video remixing, and creator monetisation tools.
By moving away from the resource-intensive task of operating a base-layer blockchain, the team expects to redirect computational, financial, and engineering overhead directly into AI model integration and user-facing applications. This aligns with a broader trend across the cryptocurrency sector, where infrastructure projects are increasingly integrating with artificial intelligence protocols to unlock new utility.
Historical Context: Rise, Vulnerabilities, and Competition
To understand Harmony’s pivot, one must examine its trajectory over the last several years. Launched during the height of the 2018-2019 blockchain expansion, Harmony emerged as an ambitious proof-of-stake network designed to solve Ethereum’s scalability bottleneck. By utilizing effective proof-of-stake (EPoS) and state sharding, Harmony promised fast transaction finality and micro-transaction fees.
During the 2021 bull market, Harmony experienced rapid adoption. It became a hub for popular decentralized applications, notably the cross-chain gaming hit DeFi Kingdoms, and attracted hundreds of millions of dollars in total value locked (TVL). However, the network faced a catastrophic setback in June 2022 when its cross-chain Horizon Bridge was exploited by malicious actors, resulting in a loss of approximately $100 million in digital assets.
The bridge hack crippled user trust, de-pegged key bridged assets on the network, and severely drained ecosystem liquidity. Despite subsequent efforts by the core team and community to restructure debt and restore operational stability, Harmony struggled to regain its peak momentum amidst an increasingly competitive market dominated by Ethereum Layer-2 rollups like Arbitrum, Optimism, and Base.
The Broader Trend: Alt-L1 Realities in a Post-Rollup Era
Harmony’s proposed transition underscores broader structural shifts within the crypto industry. During previous market cycles, alternative Layer-1 blockchains competed directly against Ethereum by offering higher throughput and lower fees. However, the rise of Layer-2 scaling solutions and modular blockchain architectures has fundamentally altered the competitive landscape.
Maintaining an independent set of validators, securing cross-chain bridges, and attracting developer talent requires immense capital and ongoing token emissions. For many mid-cap Layer-1 networks, the cost of securing a native consensus layer outweighs the benefits, especially when Ethereum now offers low-cost transactions through its own scaling ecosystem.
Conclusion: What Lies Ahead for ONE Holders
Harmony’s proposal represents a drastic yet pragmatic pivot from base-layer network operator to specialized application developer within the AI media landscape. While the sunsetting of a network marks the end of an era for its early adopters and validator community, the move to Ethereum offers a potential lifeline by tapping into deep liquidity and established security.
As the community reviews the details of the proposal, ONE holders and ecosystem participants must prioritize clearing their positions across Harmony smart contracts before the September 10 deadline to ensure a smooth transition into the upcoming AI video venture.
