Harmony Proposes ONE Token Migration to Ethereum, Wind-Down of Mainnet by 2026
TREE NEWS reports: Harmony Protocol has announced a proposal to migrate its native token ONE to Ethereum and gradually shut down its mainnet. Citing threats from state-level actors and AI agents, the team stated that since the mainnet launch in 2019, the community has faced attacks and changes, but now is the time to fully close the network.
Key Details of the Transition Plan
- Validator transition: Validators can stop operating nodes from September 10, 2026, 7:00 AM Pacific Time. Harmony will compensate validators for the difference between their last block and the network’s final block issuance rewards.
- Compensation pool: Validators and delegators who shut down on time, sign agreements, keep staking, and take on governance roles in the new plan will receive one-time compensation paid quarterly, totaling $1.372 million.
- Token migration: A new ONE token will be airdropped on Ethereum mainnet, with exchange listings migrated. At the final block, tokens in user wallets, staking delegations, validator rewards, smart contracts, or centralized exchanges will be snapshotted. Holders, delegators, or validators need not take action or claim; new ONE will be airdropped to the same wallet addresses on Ethereum.
- Incompatibility warning: Multi-sig vaults, liquidity pools, and on-chain applications cannot be migrated. Users must exit all smart contracts by September 10, 2026.
The proposal is for reference only and non-binding; plans may still change.
Industry Analysis
This move underscores the growing security challenges faced by independent layer-1 networks. Harmony’s reference to state-level actors and AI agents highlights an evolving threat landscape where sophisticated attacks can overwhelm smaller chains. The decision to migrate to Ethereum—the most secure and battle-tested smart contract platform—reflects a broader trend of ‘security consolidation.’
For the RWA and DeFi sectors, this migration signals that interoperability and security are paramount. While Harmony may not have been a major RWA hub, its departure from being a standalone chain reduces the diversity of L1 ecosystems but strengthens Ethereum’s dominance. The compensation mechanism is notable: it attempts to fairly reward validators and delegators for their loyalty, setting a precedent for future network wind-downs.
Forward-Looking Perspective
If the proposal passes, we could see more small-to-mid-cap L1s considering similar exits, especially those struggling with security costs or low adoption. The migration process itself—snapshotting state and airdropping to Ethereum—serves as a template for token migration. However, the non-binding nature and long timeline mean that market participants should monitor governance votes closely. For ONE holders, the airdrop should be seamless, but those in DeFi protocols must act before the deadline. This event may also accelerate the trend of ‘Ethereum as a settlement layer’ for other chains, reinforcing its position as the ultimate security backstop.
