Polkadot price jumps 10% after bridge exploit sell-off, eyes $1.42 resistance next

Polkadot's price rebounded over 10% after a sharp sell-off caused by a security breach on the Hyperbridge gateway, which allowed an attacker to mint bridged DOT tokens on Ethereum. The exploit did not affect Polkadot's core network security, easing investor fears and prompting a recovery from the oversold conditions near $1.15. With major exchanges resuming normal services, Polkadot tested resistance at $1.31, and a break above this level could lead to further gains toward $1.42 in the short term.
