Harmony has proposed sunsetting its Layer-1 mainnet launched in 2019 and migrating ONE to Ethereum via a final-block snapshot and ERC-20 airdrop. Multisigs, LPs, and on-chain apps will not migrate — users must exit before Sept 10. The proposal is non-binding and follows the Aug 11 cross-shard exploit.
Harmony has proposed shutting down the Layer-1 mainnet it launched in 2019 and migrating ONE to Ethereum as an ERC-20 via a final-block snapshot and airdrop.
The proposal is non-binding. Plans are subject to change.
Wallet balances, staking delegations, validator rewards, and exchange holdings would be captured automatically at the final block, with no claim required. New ONE would be airdropped to the same addresses on Ethereum. Total supply and the emission rate would remain unchanged.
Multisig safes, liquidity pools, and on-chain applications will not migrate. Harmony has urged users to exit those positions before 10 September 2026. The announcement does not describe a remedy for assets left in those contracts after the cutoff.
Any validator may cease operating from Thursday, 10 September 2026 at 7 a.m. Pacific Time. Harmony says it will compensate validators for the difference in emission rewards between each node’s last block and the network’s final block.
Validators who sunset on time, sign an agreement, keep stakes, and serve as governors would be paid in four quarterly instalments from a $1.372 million pool — equal to network-wide rewards issued in the one-year period before the 11 August incident.
The proposal follows an 11 August cross-shard exploit. An attacker abused receipt verification to mint ONE without a matching debit. On-chain analyst Juiceberg stamped roughly 4 billion ONE forged — about 26% of circulating supply — with about 2.8 billion moved to centralized exchanges. SlowMist logged realized extraction at approximately $3.2 million. Harmony rolled the chain back to 23:25:37 UTC on 11 August, erasing 109,126 regular transactions and 315 staking transactions.
Tokens issued through emissions would be reallocated to an initiative Harmony calls The Remix Economy for AI Video, subject to governor feedback. The proposal invites validators to join as AI video operators or affiliates, with first-year GPU subsidies and affiliate commission terms.

The SEC accelerated approval of Nasdaq Texas Rule 5711(d) under Order 34-106268, defining digital commodity and citing Bitcoin, Ether, Solana, and XRP as meeting eligibility. Funds may hold up to 15% NAV in non-qualifying assets. This is an exchange listing standard, not new federal commodity law.
Ledger CTO Charles Guillemet said about 4,000 BTC were pegged out of the Liquid bridge with an OP_RETURN whitehat message. Liquid said funds moved via SideSwap’s Peg-out Authorization Key, the key was not compromised, and LBTC deposits and withdrawals are paused. Other Liquid assets are unaffected.
U.S. Senator Cynthia Lummis said that if the CLARITY Act does not pass during the current Congress, the next real opportunity for market structure legislation may not come until 2030. She said finishing the bill now could avoid years of lost jobs, investment, and tax revenue.
