Harmony ONE Token Plummets 40% After 4 Billion Tokens Minted in Security Breach
  • Harmony’s ONE token plunged roughly 40% after an apparent exploit minted around 4 billion new ONE tokens, a move that could dilute the supply by about a quarter before the attack was slimmed down on-chain.

  • On-chain data suggests about 115 million ONE remained in minting addresses, with the rest moved to exchanges or deposit wallets; however, Cointelegraph could not independently verify these figures.

  • The token traded near $0.00087 at press time, down about 29% for the day after hitting a session low.

  • The article notes ongoing updates and urges readers to follow for the latest developments.

  • Options activity shows hedging for a potential move, with the $70,000 BTC call among the most traded and BTC strangles favored to profit from a sharp move in either direction.

  • Overall market participation remains subdued, with open interest in major assets like Bitcoin and Ether low, signaling limited momentum.

  • Pepeto promotes a zero-fee cross-chain swap engine and eyeing a Binance listing, arguing audited infrastructure and ready-to-use tools attract capital despite volatility.

  • The broader context includes ongoing blockchain security concerns, such as Ravencoin’s rollback discussions after invalid blocks, underscoring risks and trade-offs of rolling back transactions.

  • As of now, the size and location of excess supply, frozen funds, and rollback scope remain unresolved, leaving final resolution open.

  • Harmony’s validators were instructed to upgrade to implement the patch, with talk of a possible rollback to mitigate economic impact.

  • Derivatives positioning shows a bearish tilt among takers, with the long-short ratio at 51.36% shorts, indicating downward pressure despite overall market stagnation.

  • Monero (XMR) rose about 5.8% on the day, while AI-themed tokens like NEAR, FET, and TAO posted modest gains as AI optimism improves.
