Harmony Shutdown Moves ONE to Ethereum Amid Security Risks
Harmony has proposed a Harmony shutdown of its independent Layer 1 blockchain and a 1:1 migration of ONE to Ethereum as an ERC-20 token. A final-block snapshot would determine allocations for wallet balances, exchange holdings, staking delegations and validator rewards, with ordinary holders expected to receive tokens without a manual claim.
The plan remains non-binding. Harmony has not set the final block or permanent shutdown date, and says the token supply and emission schedule would remain unchanged. Multisignature wallets, liquidity pools and other smart-contract positions cannot migrate automatically. Users are being urged to withdraw affected assets before 10 September 2026.
The proposal follows repeated security failures, including the 2022 Horizon Bridge theft and a recent August exploit. The two reports cite materially different figures: one describes about 3.01 trillion forged ONE across six transactions, while the later report alleges nearly 4 billion unauthorised tokens, or about 26% of total supply. Harmony also cited risks from state-sponsored attackers and AI agents. It has allocated $1.372 million for eligible validators and delegators that shut down nodes on schedule and remain network governors. Some validators could support a proposed AI-focused economy involving GPU operators and creators.
For ONE traders, the Harmony shutdown creates risks of selling pressure, liquidity disruption, migration losses and uncertainty over token distribution. It could also strengthen Ethereum’s role as a settlement network for smaller chains. At the time of the later report, ETH traded near $2,508, with support around the low-$2,400s and resistance near $2,534. A break above resistance could target $2,700, while a fall below $2,400 would weaken its higher-low structure.
Bearish
The direct impact on ONE is bearish because the proposed Harmony shutdown follows major security incidents and declining ecosystem activity. The migration may trigger short-term selling as holders reassess recovery prospects, while users of liquidity pools, multisignature wallets and on-chain applications face operational risks. Conflicting reports about the exploit size and the lack of a binding final shutdown date add uncertainty, which can widen spreads and reduce liquidity.
The planned 1:1 Ethereum conversion and unchanged supply schedule could limit permanent dilution concerns if executed transparently. Ethereum migration may also preserve some utility and improve settlement security over the longer term. However, the need to withdraw assets from unsupported contracts, possible migration losses and uncertainty over the final distribution process are likely to keep ONE under pressure in the short term. Historical reactions to chain shutdowns and exploit-related migrations typically include elevated volatility, reduced market depth and precautionary selling. The overall price bias for ONE is therefore bearish, despite potential long-term benefits from Ethereum integration.
