Harmony floats plan to wind down its Layer-1 and migrate ONE to Ethereum

Harmony has outlined a proposal to retire its Layer-1 blockchain and transition its native ONE token onto Ethereum, according to multiple reports dated September 7. The plan would replace ONE with an Ethereum-based version of the token for existing holders. Some reports say the conversion could be handled automatically, without users having to submit claims. Key parameters—including the swap timeline, implementation method, and any conversion ratio—have not been disclosed in the reporting available so far. Harmony launched several years ago positioning itself as a low-fee, high-throughput alternative to Ethereum, built on a sharded architecture designed to scale transaction capacity. Despite its technical pitch, the network has struggled to sustain developer activity and liquidity at levels comparable to Ethereum and its Layer-2 ecosystem. The proposed shutdown reflects a wider industry trend: a number of mid-sized Layer-1 networks have seen usage decline as capital and builders concentrate around Ethereum, its rollups, and a smaller set of alternative chains such as Solana. Migrating to Ethereum signals an emphasis on its deeper liquidity, mature tooling, and security track record. A move would also place ONE holders closer to the largest base of DeFi protocols, exchanges, and wallet infrastructure, potentially improving custody options, trading access, and integrations with existing decentralized applications. The proposal is not described as final. Governance actions of this kind typically require feedback and approval from the community and/or validators before execution. Current reports do not cite a specific shutdown date for Harmony's chain or a firm schedule for when the migrated token would be tradable on Ethereum. Operational questions remain unresolved, including the future of Harmony's validator set, cross-chain bridge infrastructure, and applications deployed on the network. Projects built on Harmony would need to decide whether to migrate to Ethereum or another platform. Reporting to date has not detailed what support, if any, will be offered to builders during the transition. Market impact: A network wind-down and token migration could affect ONE liquidity in the near term as exchanges and market participants adjust to an Ethereum token standard. Trading pairs, wallet support, and exchange listings tied to the original Harmony chain would likely require updates to reflect the new asset. More broadly, the development underscores the consolidation pressure facing smaller Layer-1 ecosystems. FAQ - What is Harmony proposing?
