Harmony is officially sunsetting its mainnet and migrating $ONE to Ethereum.

After 7 years since 2019 launch, the team cites state actor threats and AI agent risks as too severe to continue. The network will shut down on Sept 10, 2026.

Key details:

Validator transition program: $1.372M compensation pool for validators who sunset nodes on time, sign agreements, and retain stakes. Option to become governors or join new AI video initiative with GPU subsidies and up to $1M revenue potential in year one.

Token migration: Full snapshot at final block. All $ONE in wallets, staking, rewards, contracts, and CEXs will be airdropped 1:1 to Ethereum addresses. No claim needed for holders or delegators. Multisigs and LP positions cannot migrate - users must exit contracts before Sept 10.

Total supply and emission rate unchanged. Future emissions allocated to new AI video economy mission, pending governor approval.

Contracts, snapshot calcs, and airdrop scripts will be published for public audit.

This is a rare full chain sunset with migration path. If you hold $ONE in smart contracts or LPs, you have ~18 months to exit or risk losing funds.
