Harmony Protocol to shut down and migrate to Ethereum amid AI and state‑actor threats
Harmony to wind down and move to Ethereum
Harmony Protocol announced on X that it will shut down its blockchain and migrate its ONE token to Ethereum. The decision was driven by concerns that state actors and artificial‑intelligence agents pose too great a threat.
Key points
- Harmony launched in 2019 and will close its network.
- The project will snapshot user balances and airdrop ONE to the same wallet addresses on Ethereum.
- Tokens locked in smart contracts cannot be moved; users have three days to withdraw them.
- Recent hacks, including an August 11 exploit that minted 3 trillion ONE tokens, have hurt the protocol.
- Ethereum itself has seen many security incidents in 2026, many linked to AI‑driven attacks.
Official X announcement
In a post on X, Harmony said the network would be sunset and that the ONE token would be safer on Ethereum. The message referenced “threats posed by state actors and AI agents.”
Migration mechanics
The migration will be based on a snapshot of user balances. Those balances will be airdropped to the same wallet addresses on Ethereum. Users who have funds deposited in smart contracts were given a three‑day warning to withdraw before the shutdown.
Security context
CertiK’s first‑half‑2026 report recorded 344 security incidents across blockchains, with 153 (about 44 %) occurring on Ethereum. The report suggests a rise in AI‑generated attacks. While Ethereum is considered a robust base layer, safety ultimately depends on the code of each individual project.
What is confirmed
- Harmony will close its network and move to Ethereum.
- The migration will use a snapshot and airdrop ONE to Ethereum addresses.
- Tokens in smart contracts must be withdrawn within three days.
- An August 11 exploit minted 3 trillion ONE tokens, which the team rolled back.
- ONE’s price fell more than 40 % over the past month.
What remains unclear
- Whether moving to Ethereum will protect ONE from future AI‑related attacks.
- Exact timeline for the full migration beyond the three‑day withdrawal window.
Why it matters
Harmony’s shutdown highlights how smaller blockchains are vulnerable to sophisticated attacks, especially as AI tools become more powerful. Migrating to a larger, more widely audited platform like Ethereum may reduce some risks, but the broader trend of AI‑driven exploits means security challenges persist across the crypto ecosystem.
Next steps
Users with funds in smart contracts should withdraw within the three‑day notice period. After the shutdown, ONE balances will appear on Ethereum, and former validators may take new roles as governors, AI video operators, or affiliates.
